We bring a bricked smartphone back to life. Lenovo p780 does not turn on after firmware Repair Lenovo p780 recovery after unsuccessful firmware

Most of the articles in the X-Mobile section are devoted to hacks and tweaks that require obtaining root rights, modifying the firmware, or replacing it with a custom one. However, not every reader is ready to subject their smartphone to such operations, fearing that they can turn the device into a brick or lead to instability in operation. Today I will debunk these myths and show that even in the most stalemate situation, bringing a smartphone back to life is not so difficult.

Destroying myths

Let's talk about what it really means to “turn a smartphone into a brick” and what other pitfalls can await the user on the way to changing the system and installing custom firmware. What glitches can be caught in this case and is it possible to kill a smartphone by reflashing it incorrectly? Will you lose the warranty forever or can the smartphone be returned to its previous condition? Can custom firmware really fail a smartphone owner at the most inopportune moment and are they worth it?

Myth 1. Incorrect flashing can kill a smartphone

A fall from the fifth floor can kill a smartphone, but not flashing it. The main problem that anyone who wants to reflash a smartphone faces is that during the installation of the firmware, a failure may occur, which will lead to its inoperability, and the smartphone will actually turn into a brick.

All this is true, but only on paper. To understand why, it’s enough to understand how the process of flashing a smartphone works and what system components are used. To be able to install third-party firmware on a smartphone, you need to unlock the bootloader (not in all cases), get root and install a custom recovery console (ClockworkMod or TWRP), capable of installing firmware with any digital signature.

The recovery console is stored in a separate partition of the internal NAND memory and is in no way connected with the installed operating system. After installing a modified version of the console, it will be possible to flash custom firmware or even another OS (Firefox OS, for example). If a failure occurs during the installation of the firmware, the smartphone will not be able to boot it, but the recovery console will remain in place, and all you need to do is boot into recovery again and reinstall the firmware.

In addition, any custom recovery console contains a backup/restore function, which allows you to make a backup copy of the main firmware and restore it unchanged (with all applications, settings and data) in the event that something goes wrong. In fact, the smartphone can be returned to its original state.

You may ask: what happens if the installation of the Recovery Console itself fails? Nothing, in this case the situation will be the opposite, when the operating system itself will remain in place, and the console will be lost. To deal with it, you just need to re-flash recovery directly from Android.

Hypothetically, one can imagine a situation where both the firmware and the recovery console are killed (although this is quite difficult to do), but even in this case, the primary bootloader, flashed into the permanent memory of the smartphone, will always remain in place.

Conclusion: it is impossible to kill a smartphone by installing third-party firmware through a custom recovery console. Either the recovery or the primary bootloader will always remain in place.

Myth 2. Custom firmware is unreliable

Firmware is different from firmware. On the vastness of the World Wide Web you can find a huge number of Android builds for every taste and color, and most of them are really slag, which can lead to instability in the operation of the smartphone and loss of some functionality. Therefore, the first thing to remember is that you should only deal with serious custom firmware developed by large teams of experienced developers. First of all, these are CyanogenMod, Paranoid Android, AOKP, OmniROM and MIUI.

Second. There are two types of firmware: officially supported and ported by third-party developers. The same CyanogenMod, for example, has an official version for the Nexus 4 smartphone, but does not have one for the Motorola Defy. But for Defy there is an unofficial port of CyanogenMod 11 from a developer with the nickname Quarx. The difference between them is that the CyanogenMod team is responsible for the support and proper operation of the first, while the second is Quarx personally. Official firmware versions are usually fully functional, but the correct operation of the latter depends on the third-party developer.

Well, third. There are stable and development versions of the firmware. Stable versions of CyanogenMod have the index M (CyanogenMod 11.0 M7, for example). This firmware version usually does not contain bugs. Development versions (in the case of CyanogenMod these are daily nightly builds) may contain bugs and are therefore not recommended for everyday use.

Conclusion: if you install a stable official version of the “normal” firmware on your smartphone, the risk of encountering bugs is minimal. Everything else is for experimenters.

Myth 3. Software that requires root rights can brick a smartphone

In theory, an application with root rights can do anything with the smartphone's firmware, including erasing it completely. Therefore, you need to be extremely careful with such software. The software we talk about on the pages of the magazine is completely safe and tested in our own skin. In addition, for all the time I have been using smartphones on Android (and this is starting from version 1.5), I never I haven’t encountered a situation where software with root support killed a smartphone.

Software distributed through Google Play usually fully corresponds to the stated characteristics, and if it led to a brick or left a backdoor in the depths of the smartphone, it would not last even a week in the store. In any case, here you need to follow the “trust but verify” rule and carefully read the instructions for using root applications.

Myth 4. Root rights make a smartphone vulnerable to viruses

What makes a smartphone vulnerable to viruses is not root rights, but the bugs used to obtain them. Rooting tools and viruses can exploit the same Android vulnerabilities to gain root privileges, so the fact that the device is rooted does not change anything. A well-written virus will not ask for permissions in the standard way, revealing its presence; instead, it will take advantage of the same vulnerability to obtain them covertly.

Moreover, having root, you get the opportunity to install the latest version of Android (in the form of custom firmware), in which these bugs are already fixed. Also, do not forget that most custom firmware allows you to disable root or create white lists of applications that can use these rights.

Myth 5. A rooted smartphone may fail

Software designed to obtain root does four simple things: launches an exploit that allows you to gain root rights in the system, mounts the /system partition in write mode, copies the su binary required to obtain root rights in the future to the /system/xbin directory, and installs the SuperSU or SuperUser application, which will take control whenever any application requests root privileges using su.

None of these steps can crash or kill the smartphone. The only thing that can happen is that the exploit will cause a segmentation fault and the smartphone will reboot, after which it will continue to work normally.

Myth 6. By getting root and installing custom firmware, I will lose the warranty

The guarantee is lost not from the fact of obtaining root, but due to its detection by the service center. Most devices can be unrooted using the Universal Unroot application or by reinstalling the stock firmware using the official application from the manufacturer.

There are, however, two exceptions to this rule. The first is the Knox system that comes pre-installed on new Samsung smartphones and tablets such as the Galaxy S4, S5, Note 3 and Note 10.1. Knox provides an increased level of Android security by responding to any firmware modifications and installation of third-party kernels and firmware. If the user performs these actions, the system sets a trigger that confirms the fact of the modification. The trigger is implemented in hardware (eFuse chip), so it cannot be reset to its initial position. On the other hand, it is not entirely clear whether the service center will refuse to repair the device on this basis. Second: the eFuse chip is installed on some other devices (for example, smartphones from LG), and it also allows you to accurately determine whether the smartphone has been rooted or flashed.

If we talk about custom firmware, everything is more complicated. Typically, the flashing operation requires unlocking the bootloader, and this can be done either using special exploits or using the smartphone manufacturer's web service. In any case, the unlocked bootloader will definitely indicate that the smartphone did not belong to a blonde.

On some smartphones, it is possible to lock the bootloader back, but you should learn about this separately, and also keep in mind that the newly locked bootloader will most likely receive the status Re-locked, and not Locked, as it was originally (this happens on HTC smartphones, For example). The only exceptions here are smartphones and tablets of the Nexus line, the bootloader of which can be locked and unlocked in three clicks without any dancing with a tambourine, and no one will find fault with anything.

INFO

On Linux, ADB and Fastboot can be installed separately from the Android SDK. On Ubuntu: sudo apt-get install android-tools-fastboot. On Fedora: sudo yum install android-tools.

To prevent Knox from interfering with root applications, you can disable it using the following command from the terminal: su pm disable com.sec.knox.seandroid.

conclusions

Getting root and flashing a smartphone are absolutely safe operations that cannot brick the smartphone for purely technical reasons. The only exception is an attempt to hack the bootloader in order to unlock it. In this case, the eFuse chip (if the smartphone has one) may work and block the ability to turn on the smartphone.

Fortunately, today smartphone manufacturers either prefer not to block the ability to turn on a smartphone with a hacked bootloader (by setting a trigger indicating the fact of such an action, as Knox does), or implement a special web service that allows you to painlessly unlock the bootloader with loss of warranty on the smartphone. which saves users from having to risk breaking the bootloader.

Problems that may arise during flashing

So, now let's talk about what problems can arise when getting root and flashing and how to deal with them.

Scenario one: after an unsuccessful flashing, the smartphone stopped booting

Unsuccessful flashing can be caused by several factors: the battery died and the firmware was only half filled; the firmware turned out to be faulty or intended for a different smartphone model. In the end, there was simply not enough space on the smartphone, which can happen when trying to install the latest version of Android on a smartphone that is three or four years old.

Outwardly, all these problems usually manifest themselves either in endless resets of the smartphone to the initial manufacturer logo, or in the so-called boot loop, when the boot animation plays on the screen for more than five to ten minutes. There may also be problems with the screen (multi-colored ripples) and a non-working touch screen, which also prevent the use of the smartphone.

In all these cases, it is enough to do one simple thing: turn off the smartphone by long pressing the power button, then turn it on while holding down the volume down button (some smartphones use a different combination), and after you get into recovery, reinstall the firmware (Install zip from sdcard - > Chooze zip from sdcard) or restore the backup (Backup and restore -> Restore). Everything is easy and simple.

Scenario two: the firmware works, but recovery is not available

This can happen after a failed installation or update of the Recovery Console. The problem is that after rebooting the smartphone and turning it on while holding down the volume down button, a black screen appears, after which the smartphone either resets or freezes.

Solving this problem is not easy, but very simple. You can install the recovery console on the vast majority of smartphones using the TWRP Manager, ROM Manager or ROM Installer applications. They themselves determine the smartphone model, download and flash the required recovery, without requiring a reboot. If you can’t restore the console with their help, just find instructions on the Internet for installing recovery on your device.

Scenario three: neither firmware nor recovery is available

To be honest, it is difficult for me to imagine such a scenario, but, as practice confirms, it is quite real. There are two ways to get out of this situation: use fastboot to upload recovery to your smartphone, or use a tool from the manufacturer to install stock firmware. We'll look at the second method in more detail in the next section, and I'll talk about fastboot here.

Fastboot is a tool that works directly with the device’s primary bootloader and allows you to upload firmware to your smartphone, recovery, and unlock the bootloader (in Nexus devices). Fastboot support is available in many smartphones and tablets, but some manufacturers block the ability to use it. So you will have to consult the Internet about its availability.

To access fastboot, you will need drivers and the Android SDK. When they are installed, open the command line, go to the SDK installation directory, then to the platform-tools directory, turn off the smartphone, turn it on with the volume buttons pressed (both) and connect it using a USB cable to the PC. Next, you need to find the recovery image in .img format for your device and run the command:

$ fastboot flash recovery image.img

Or even force the smartphone to boot recovery without actually installing it:

$ fastboot boot image.img

In the same way you can flash official firmware update:

$ fastboot update update-file.zip

You can find a recovery suitable for your device either on the TWRP website or in the XDA-Developers and 4PDA forums.

We return the smartphone to its original state

In this section, I will talk about ways to return your smartphone to clean stock, no matter what state it is in. These instructions can be used both to unbrick your smartphone and to remove traces of rooting and flashing. Unfortunately, I can’t talk about all possible models, so I’ll focus on the four most popular flagships: Nexus 5 (I call this sample the control one), Galaxy S5, LG G2 and Sony Xperia Z2.

Nexus 5 and other Google phones

Restoring Nexus devices to their original state is easier than any other smartphone or tablet. In fact, it is so simple that there is not even anything to talk about. In fact, all you need to do is install the ADB/fastboot drivers (on Linux you don’t even need them), download the archive with the firmware and run the script. The whole operation looks like this step by step:

from here.
Download and install Android SDK.
Download the archive with the firmware for the desired device from the Google website.
Turn off the device, turn it on with the volume buttons pressed (both) and connect using a USB cable.
Unpack the archive with the firmware and run the flash-all.bat (Windows) or flash-all.sh (Linux) script and wait for the operation to complete.
We launch the command line, go to the directory with the Android SDK, then platfrom-tools and execute the fastboot oem lock command to lock the bootloader.

For those who are interested in what the script does, here is a list of commands:

Fastboot flash bootloader bootloader-DEVICE-NAME-VERSION.img fastboot reboot-bootloader fastboot flash radio radio-DEVICE-NAME-VERSION.img fastboot reboot-bootloader fastboot flash system system.img fastboot reboot-bootloader fastboot flash userdata userdata.img fastboot flash recovery recovery.img fastboot flash boot boot.img fastboot erase cache fastboot flash cache cache.img

Galaxy S5

With the Galaxy S5 smartphone everything is a little more complicated, but overall quite simple. This time you will need the Samsung Odin application, which will be used to flash the smartphone’s firmware. Sequencing:

Download and install the latest version of Samsung USB drivers from here.
Download and install the latest version of Odin from here.
Go to the website samfirmware.com, enter the SM-G900F model in the search, find the firmware marked Russia, download and unpack.
Turn off the smartphone and turn it on with the Volume Down and Home buttons pressed, wait five seconds until a warning message appears.
Press the volume up button to put the smartphone into Odin mode.
We connect the smartphone using a USB cable.
Launch Odin, press the PDA button and select the file with the extension tar.md5 inside the directory with the unpacked firmware.
Click the Start button in Odin and wait until the firmware process is completed.

As I already said, this operation will return the smartphone to its original state, but will not reset the trigger installed by the Knox system (if it was in the standard firmware). Therefore, the service center may refuse to repair.

LG G2

Restoring the LG G2 to its factory state will also not cause any problems. The number of steps in this process is somewhat larger, but they themselves do not require special preparation and knowledge. So, what to do to return the G2 to factory firmware:

Download and install ADB Driver Installer from here.
Download the official firmware (Europe Open 32G or Europe Open) from here.
Download and install LG Mobile Support Tool, as well as FlashTool (goo.gl/NE26IQ).
Turn off the smartphone, hold down the volume up button and insert the USB cable.
Expand the FlashTool archive and run the UpTestEX.exe file.
In the window that opens, select Select Type -> 3GQCT, Phone Mode -> DIAG, in the Select KDZ file option select the firmware downloaded in the second step.
Click the CSE Flash button at the bottom of the screen.
In the window that opens, click Start.
In the next window, select the country and language and click Ok.
We wait for the firmware to finish, and then turn off and turn on the smartphone.

This is all. But keep in mind that, as in the case of Samsung, the smartphone will still have Rooted status, and this cannot be fixed.

Sony Xperia Z2

Now about how to return the Sony Xperia Z2 smartphone to its factory state. As in the previous two cases, this will require stock firmware and the official firmware utility. You launch the utility on your PC, connect your smartphone using a USB cable and start the update process. Step by step it all looks like this:

Download and install ADB Driver Installer from here.
Reset your smartphone to factory settings.
Download and install the Flash Tool from the official Sony website and the latest firmware from here.
Copy the firmware file to the C:/Flashtool/Firmwares directory.
Turn off the smartphone and turn it on while holding down the Volume Down and Home keys.
We connect the smartphone to the PC using a USB cable and launch the Flash Tool.
Click the button with the lightning icon in the Flash Tool. In the window that opens, select Flashmode, double-click on the firmware in the list that opens.

WARNING

In many smartphones, an unlocked bootloader will not allow an over-the-air update.

In 90% of cases, unlocking the bootloader will entail deleting all data from the smartphone, including the memory card.

conclusions

Flashing a smartphone, and even more so gaining root access, is not at all such a scary and dangerous operation as it may seem at first glance. If you do everything correctly and do not resort to tools that unlock the smartphone’s bootloader, bypassing the manufacturer’s tools, you will not be able to brick your smartphone. Yes, in some cases you will have to tinker to get everything back in place, but what is better - to use a locked smartphone that does not allow you to do even half of the things that it is capable of, or to gain complete control over the device? In the end, reinstalling Windows on a PC doesn't scare anyone.

Few models of Android smartphones from the famous manufacturer Lenovo can be characterized by such a level of prevalence and popularity as the IdeaPhone P780. This is indeed a very successful device at the time of its release and, despite the fact that this phone is considered obsolete, its technical characteristics allow it to satisfy most of the needs of the average user today. Below we will talk about working with the system software of the device in terms of its restoration, replacement and updating, that is, about the firmware of the model.

Lenovo software components can be updated, reinstalled, customized, and, if necessary, restored using tools and methods available to all users. Almost all situations that may arise are described in the instructions below, but before seriously interfering with the software part of the device, you should consider:

When performing operations in accordance with the recommendations below, the user is aware of the potential risks of the procedures. All actions are performed by the owner of the device at his own peril and risk and only he is responsible for their results and consequences!

Before manipulating the software part of any Android device, it is necessary to carry out certain preparatory actions with the device and the computer that will be used as a tool for transferring data to the device. Having completed the preparation in full, you can avoid many mistakes and very quickly achieve the desired result - a correctly and stably functioning Lenovo P780 smartphone.

Hardware revisions

In total, there are as many as four versions of the Lenovo P780 model, which differ not only in the region of use intended by the manufacturer (two options for the Chinese market and two international revisions), the software part (memory layout - for devices for China - CN, for international ones - ROW), year of manufacture (devices are conventionally divided into those released before and during 2014), but also in hardware (different ROM sizes - 4 GB and (only for “international”) 8 GB, different radio modules).

Firmware methods and software tools for different model variants do not differ, but different versions of system software packages are used. This material demonstrates universal methods for reinstalling and restoring the OS for the model, and using the links provided in the article you can find software suitable for “international” smartphones with a memory capacity of 4 and 8 GB.

For the “Chinese” versions, the reader will have to search for archives with system software files on their own. To help with such a search, we note that a good selection of official and modified operating systems for all revisions of the device is collected on the website, but registration will be required to download files from the resource.

The instructions discussed below were applied to a device with a memory capacity of 8 GB, intended for the international market - these are the smartphones that were officially sold in the CIS and are by far the most common. You can distinguish the model from the versions for China by the inscriptions on the battery by removing the back cover.

The information for the international versions is in English, while for the “Chinese” versions there are hieroglyphs and a blue sticker.

Drivers

The first thing you need to do before proceeding to install Android on the Lenovo P780 is installing specialized drivers.

Methods for connecting inoperative smartphones that are not detected by the computer are described below in the description. "Method 3: Scattering". In this case, the driver package posted at the link above is used!

Root rights

Obtaining Superuser privileges on the model in question should be considered an accompanying rather than a preparatory procedure before reinstalling the system. At the same time, root rights may be required to create a full backup of the system and other manipulations that precede intervention in the software part, as well as necessary in its daily work, so knowing how to get them can be useful to many users.

Equipping your phone with root rights is done using the Framaroot tool, which usually does not cause difficulties even for beginners. Just download the apk file using the link from the product review article on our website and follow the instructions from the lesson:

Backup

Copying information usually stored in a smartphone to a safe place is a must before flashing the Lenovo P780 firmware, because if you manipulate the device’s memory sections, all information will be destroyed! Users of the model are highly recommended to make backups in any available way and whenever possible.

There are quite a large number of methods for protecting against data loss, and the most effective of them are described in the article:

In addition to the loss of personal information, users who manipulate the system software of the model in question may encounter another nuisance - loss of functionality of communication modules, which occurs after overwriting "IMEI" and/or is a consequence of partition damage "NVRAM".

It is highly recommended to create a dump "NVRAM" before any operations with the smartphone not documented by the manufacturer, then restoring this partition, if it is damaged, will not take much time and will not require serious effort.

It's much easier to create a backup "NVRAM" at the first opportunity, rather than if this area of memory is damaged, restore it long and hard!

One of the simplest methods for creating a backup "NVRAM" is to use the MTK Droid Tools.

Restoring an area "NVRAM" is carried out by performing the above steps, only in step No. 5 the button is selected "Restore".

Android installation, update, recovery

After completing the preparation, you can proceed to directly flashing the Lenovo P780 firmware, that is, overwriting the system partitions of the smartphone’s memory using specialized software. Below are the official and more universal ways of working with the device OS in various situations. A method for restoring inoperative devices and installing modified (custom) firmware is also presented.

The choice of interaction method is determined by the initial state of the smartphone and the desired result, that is, the version of Android under which the phone will operate in the future.

Method 1: Official Lenovo software

One of the few methods of interaction with Lenovo P780 system partitions documented by the manufacturer is software Lenovo MOTO Smart Assistant. This software allows you to simply and quickly update the official version of the system, that is, get the latest official firmware on your smartphone.

You can download the tool for working with Lenovo Android devices from the official website of the developer:

Having received the package from the link above, install Smart Assistant by opening the distribution file and following the installer’s instructions.

We launch the tool and connect the P780 to the USB port. Must be activated on the smartphone "USB Debugging". To enable debugging, just after connecting the phone to the PC, slide the notification shade on the screen down and check the corresponding checkbox.

The model and its characteristics are determined automatically in the program. After displaying the information in the window, go to the tab "Flash".

MOTO Smart Assistant checks for Android updates automatically. If it is possible to update the system software version, a corresponding notification will be issued.

We press the button with the image of a downward arrow located near the information about the versions of the device and the future OS, and then wait for the update files to download to the PC disk.

After all the necessary components have been received, the button will become active "Update", clicking on which will start the Android update process.

The system will remind you of the need to create a backup copy of important information in a special request window. When you are sure that everything you need has been copied to a safe place, click "Proceed".

The subsequent stages, which involve updating the Lenovo P780 system software, are carried out by the manufacturer’s proprietary tool without user intervention. The update will be transferred to the smartphone, the latter will reboot and start with the new version of the OS build.

Method 2: SP Flash Tool

The most effective tool that allows you to perform almost all possible actions with the system software of Android devices built on the Mediatek hardware platform is SP Flash Tool.

To work with the model in question, you will need a certain version of the application - v5.1352.01. You can download the archive with software files from the link:

Before you begin manipulating the P780 via FlashTool, we recommend that you read the material containing instructions for reinstalling the OS on MTK devices using the tool in the general case:

Using Flashtool, we install the latest build of the official system for the “international” version of Lenovo P780. You can always download archives with software for 4 and 8 GB versions of the model using the link below. Select a catalog that matches the hardware characteristics of the smartphone:

Unpack the archive with the software and the Flashtool program into separate directories.

Launch SP Flash Tool and load file into the program using the button "MT6589_Android_scatter_emmc.txt", located in the folder resulting from unpacking the archive with the software.

Make sure the mode is selected "Download Only" in the drop-down list of options.

Click "Download" and connect the previously turned off phone to the USB port of the PC.

The process of memory overwriting starts automatically and lasts quite a long time. You can monitor the progress of the procedure using the filling status bar at the bottom of the window.

Once the data transfer to the device is complete, a window with a green circle will appear confirming success - "Download OK".

Disconnect the USB cable from the phone and start it by holding the key for a long time "Inclusion".

After initialization, launch and configuration, we get the official Android version of the latest version released by the manufacturer for the model in question.

Method 3: "Sprinkling", IMEI repair

The instructions described above, which involve reinstalling Android on the Lenovo P780, are available for execution if the device in question is generally operational, is loaded into the system, or in any case is detected by the computer when it is turned off. But what to do if the smartphone does not turn on, does not boot and is not visible in "Device Manager" even for a short time?

This or a condition similar to it has received a comic, but at the same time very accurate name among users of Android devices - “brick”, and restoring functionality in such situations is “bricking”. To remove the Lenovo P780 from the “brick” state, you will need the one already used above SP Flash Tool v5.1352.01, package with official software version S124, as well as additional files for recovery "NVRAM" And "IMEI", if a partition dump has not been created previously.

Using the method is advisable only if all other options for reinstalling Android have been tried and do not bring results! Before you begin the manipulations, you need to read the instructions to the end and evaluate your own strengths and capabilities, as well as prepare everything you need for recovery operations!

Let’s divide the process of returning the device in question to a fully operational state into three stages: creating a situation in which the “visibility” of the device by the computer is ensured; installation of system software with preliminary full formatting of memory; restoration of the software modem, IMEI numbers, which is necessary for the full functioning of the communication modules and will be needed after formatting the smartphone.

Step 1: Getting it done "visibility" "Preloader USB VCOM" V "Device Manager".

There are only three methods by which it is possible to access a “dead” P780 from a PC.

First, let’s try pressing and holding the key before connecting the device to the USB port. "Increase volume".

Once the PC responds, you can release the volume button. If in "Dispatcher" still nothing changes, move on to the next point.
We remove the back cover of the device, remove the SIM cards and MicroSD, prepare the cable connected to the USB port of the PC, open "Device Manager".
Press the hardware button "Reset", located slightly below the memory card slot, and hold it. Without letting go "Reset", connect the micro-USB connector of the cable connected to the PC to the phone connector. Wait about 5 seconds and release "Reset".

If successful, the smartphone will be detected in "Dispatcher" as "Preloader USB VCOM" or as an unknown device on which you need to install the driver using the method described at the beginning of the article.

The connection is not always successful the first time; if success is not observed, we try to repeat the procedure several times!
When the above does not lead to the visibility of the device in "Dispatcher", the most drastic method remains - to try to connect a smartphone with a disconnected battery. To do this we do the following:

Step 2: Android Installation

If the device is identified among the devices connected to the PC, it was possible to install the driver "Preloader", we can assume that “the patient is more alive than dead” and begin rewriting the partitions, that is, installing Android.

Step 3: Restoring communication functionality

The previous “unscrapping” step allows you to restore the operating system, but formatting the partitions will lead to erasing "IMEI" and inoperability of SIM cards. If there is a pre-made dump "NVRAM", we restore the partition. If there is no backup copy, you will have to use a powerful software tool to help MauiMeta 3G. You can download the version of the tool suitable for manipulating the Lenovo P780, as well as the files necessary for recovery, from the link:

The package received from the link above needs to be unzipped.

Then run the MauiMeta installer - "setup.exe" from the program directory.

Install the application following the installer's instructions.

After installation is complete, run the tool as Administrator.

Switch the connection mode to "USB COM" by selecting the appropriate item in the drop-down list of the main MauiMeta window.

Open the menu "Options" and check the box next to the option “Connect Smart Phone into META mode”.

Calling the option "Open NVRAM Database", available in the menu "Actions",

and then specify the path to the file "BPLGUInfoCustomAppSrcP_MT6589_S00_P780_V23" from folder "modemdb" in the directory with recovery components, click "Open".

Click "Reconnect", which will cause the device connection indicator circle to flicker (red-green).

Turn off the phone, press and hold on it "Volume-". Without releasing the key, connect the IdeaPhone to the USB port of the PC.

As a result of pairing in this way, the smartphone will be switched to "META-mode".

As a result of the program correctly identifying the device, the indicator should change its color to yellow and a window will appear "Get version".

Make sure that the device and program are paired correctly by clicking "Get target version"— the hardware characteristics will be displayed in the corresponding fields, after which the window must be closed.

If MauiMeta does not respond to the connection, check that the drivers are installed correctly in "Device Manager",

and if they are missing, we install the components manually from the package available for download from the link at the beginning of this article!

Select the option from the drop-down list "Update parameter",

and then specify the path to the file "p780_row.ini" in the window that opens by clicking the button "Load from file" from the catalog with recovery components.

Click "Download to Flash" and wait until the parameter names change from blue to black, then close the window "Update parameter".

Let's move on to recovery "IMEI". Select an option "IMEI Download" from the drop-down list of the main Maui META window.

On tabs "SIM1" And "SIM2" enter in the fields "IMEI" the parameter values of a specific device instance (can be found on the phone box and its battery) without the last digit.

Click "Download to flash".

Almost instantly at the bottom of the window "IMEI Download" an inscription confirming the success of the operation appears "Download IMEI to Flash Successfully", and then close the window.

Restoration of the 3G module can be considered complete. Click "Disconnect" As a result, the device will exit "Meta-mode" and turns off.

After loading into Android, we check the IMEI by dialing *#06# in the dialer.

Once the connection is restored, you can update to the latest official version of the system. In addition, after connecting the “revived” phone to Wi-Fi, the update will “fly over the air”.

Or you can use the instructions for updating the system above in the article - "Method 1" And "Method 2".

Method 4: Custom firmware

The most interesting systems for Lenovo P780, from the point of view of attempts to “refresh” the software part and introduce, frankly, the ability to perform new functions into an outdated device, are modified unofficial shells. Due to its popularity, quite a large number of custom firmware options for the model have been created, and among them there are very interesting and fully functional solutions.

When selecting and installing various unofficial systems in the Lenovo P780, you should carefully consider the memory layout that characterizes a specific instance of the device. The following applies solely to "international" versions 4 and 8 GB. For other hardware revisions of the smartphone, the same methods of repartitioning and then installing recovery and OS are used, but you need different packages with components than those posted on the links below!

Unofficial firmware VIBE UI 2.0 + memory re-partitioning

Users of the device in question have done serious work on customizing the software part of the device, which also affected the memory layout, that is, the redistribution of the volume of its areas. To date, about 8 (!) different layout options have been created and all of them are used when porting custom.

According to the creators of this idea, the effect of repartitioning should be observed as a result of deleting the internal section "FAT" and transferring the freed volume to the system for installing applications. This is best implemented in markup called "ROW+", we will equip the device with it according to the instructions below.

Among other things, we can say that most of the popular custom solutions for the device in question are installed precisely on this markup. And also on "ROW+" You can install modern versions of modified recovery.

There are several methods to convert the partition table, let's consider the simplest one - installing one of the modified OSes intended for switching to partitioning "ROW+". In addition to the new layout, as a result of completing the steps below, we get an excellent system on the device with a modern interface from Lenovo and suitable for everyday use!

Installation of the VIBE UI 2.0 shell is carried out using SP FlashTool in the same way as the installation of the official system described in "Method 2" above in the article, but in mode "Firmware Upgrade".

The VIBE UI 2.0 shell can be used on an ongoing basis or be used as a basis for installing other custom markups "ROW+", - almost everything you need is already present in the device.

Step 2: Equipping the device with a modified recovery

Since the above installed firmware contains custom recovery TWRP version 2.8, and this solution is used to install common unofficial firmware, this step of the instructions can be omitted. At the same time, we provide instructions for those users who want to get the functionality of new versions of the recovery environment, as well as for cases when the recovery for some reason has stopped working.

Just in case, let us remind you: to enter the modified recovery on Lenovo P780, with the device turned off, you should hold down all three hardware buttons - both volume control keys and the "Inclusion", and then hold them until the main recovery environment screen appears. And you can also reboot into recovery from the shutdown menu of VIBE UI 2.0 and other custom ones.

You can download the TWRP image of the latest version at the time of writing this material from the link:

The following works on most firmwares, but the Lenovo P780 memory must be partitioned "ROW+"— it is for this type of markup that the image offered for downloading above is intended!

Installing a version of custom recovery different from the one obtained after installing VIBE UI 2.0 can be done using various methods and all of them are described in articles on our website! We download the recovery image and place it in the root of the internal storage or on a memory card, and then select the method and follow the appropriate instructions:

Upon completion of the installation of the latest version of TWRP, the Lenovo P780 can be considered fully prepared for installing and replacing with each other any custom firmware intended for partitioning "ROW" And "ROW+". Let's move on to the next step.

Step 3: Install custom via TWRP

As mentioned above, a huge number of unofficial operating systems have been created for the model in question. The choice of one or another solution depends on the user’s preferences, and the installation of a specific shell package designed for TWRP is performed according to the same algorithm.

As an example, we install one of the most popular products, available in various variations for the Lenovo P780 model - MIUI.

There are a large number of port options for this shell; we recommend choosing a solution from one of the well-known romodeling teams.

In this video I will show you how to flash a Lenovo P780 2014 phone using firmware or assembly that is designed for older Lenovo P780 phones. In this video, I will install on a 2014 Lenovo P780 phone an assembly with the VIBE interface from xaker, which was intended for older phones. I'll show you what needs to be changed so that everything is reset and you don't get a Brick.

Hi all. I already have a video on flashing the Lenovo P780 phone on my channel, but several people have already unsubscribed that the firmware that is in the description under the video is not suitable for phones released in 2014. I'm afraid I'll make a mistake, but it seems to me that at the time they wrote, I already knew that there was such a problem and in my description under the video there was firmware that I tried specifically on the 2014 P780, i.e. for a 2014 phone, this is what you see now on this Lenovo P780 phone.

I saw on my website, as well as in the comments to the video, that the guys had been flashing before and ended up with a “brick” that did not turn on. I was skeptical about this, because I flashed several dozen phones, some several times, and never had any problems, so I thought that the guys were doing something wrong, and so I thought until I myself “ I bricked my 2014 Lenovo P780 phone. I started flashing it and got a “brick”, then I started thinking that something was wrong. As it turned out, the problem is in Boot(e), that is, in the bootloader. New phones have a modified bootloader and when you install the old firmware, it installs the old Boot on the Lenovo P780. Naturally, the old Boot cannot work normally on a phone that requires a modified Boot and we get a brick P780. As soon as I found out, I immediately tested the Boot replacement on the official firmware.
One friend wanted VIBE firmware on a 2014 Lenovo P780 phone. I previously installed the VIBE firmware from the site lenovo-forums.ru, from a user with the nickname Hacker who made the VIBE firmware. Of course he didn’t make it, he assembled it from some firmware from VIBE. I tried it on old phones, it worked great and well. Several of my friends tried it, one even still sits on it, he really likes it. You can install it, you can guarantee that it will work, and at least my conscience will not torment me that the firmware does not work well, but there is one problem, the phone is 14 years old, and the firmware is old, if I flash this old firmware on the phone 2014 - I will get a “brick”. That is, I need to do something with this sewing so that I don’t get a “brick”. To do this, you just need not write the old Boot that comes with this firmware to your phone. To begin with, before any firmware, you need to install drivers for the phone. To do this, turn off the phone and go to “Device Manager”. First I will install the drivers, or rather I already have them installed, but I will show you how to do it. And then I’ll show you what you can do with the firmware so that your phone turns on.
We connect the switched off phone to the computer, a COM port appears for 2 seconds. You need to quickly right-click on it. I didn’t have time, but that’s okay. Either we reboot the phone using the button, or we unplug the cord again and insert it again. I didn't have time again! I understand everything, I have two device managers open, so I don’t have time.

Once again, quickly right-click, select “update drivers”, select “search on this computer”,

and indicate the folder into which you will unpack the archive, or rather not the archive, but the contents of this archive.

We transfer the contents of this archive somewhere, for example, to “Disk C”, and then in the “search for drivers on this computer” window, indicate “Disk C” and install the drivers. Now, when you connect the P780, a virtual COM port will appear in the device manager for two seconds, and not an unknown device.

We've sorted out the drivers, now let's move on to the firmware, the most interesting thing that can be done. I have VIBE from Xaker. On “Disk C” I made a VIBE folder, while it is empty. We open the archive and throw all the contents (FlashTools with which we will flash the firmware itself) into the folder,

I repeat - the firmware is for old phones, that is, we have an old Boot. Since the phone turns on and everything is fine with it, we need to flash the firmware without writing down Boot, that is, write down everything except Boot. Easy to say, almost impossible to do. I tried different options, and now I will show you everything.
Open FlashTools, before you open it, make sure that the cable is not connected to the phone, if it is connected, then just turn it off. Launch FlashTools, specify the scatter which is located in the folder with the firmware.

Since I have a lot of firmware, I need to be careful. The first thing that comes to mind is to simply uncheck the box, but as soon as you uncheck the box, you won’t learn to flash anything.

The second thing that comes to mind is to correct our scatter file, that is, to prohibit the firmware of only Preloader(a), that is, we open the scatter file through Notepad, in order to prohibit the firmware of this sector, you need to write “__NODL” you can write, and you can simply copy from another section and paste.

Now we save, launch FlashTools again, now we won’t have Preloader(a) in the scatter, everything will start right away from the MBR.

I tried to do this, but I got a “brick” so this method will not work for us either. The third method works for me and I recommend it to you.
We will still load Boot, but we will not load the original Boot (I will delete it), but we will use Boot, which is needed specifically for 2014 phones.
Let's fix the scooter to the state in which it was originally, namely, remove “_NODL”:

Boot for phone 2014 is in the archive, I will copy it and paste it into the folder with the firmware.

I will post all the files (separately the driver, separately the Boot, and separately the VIBE firmware) so that you can dig deeper yourself. If someone asks, I will already post this ready-made firmware to him so that he doesn’t mess around and kill his phone. Well, that's basically all. Now I launch FlashTools again and check that I select the same scatter file. Well, that’s it, then everything is standard, make sure that the phone is turned off, check the “check amount” box, press the update “software” button and connect our phone. The firmware process has begun. Please note that in the video for the first time I did not check the checkbox for the amount and received a brick. The checkboxes should be as shown in the screenshot below:

Now I'm sewing VIBE firmware. You can also change the Boot and flash any firmware, any assembly, anything, no matter whether it’s old or not. It’s better not to guess, don’t tempt fate for one place, change the Boot right away.
That's it, the phone was flashed, everything seemed to be fine, but I already had the firmware completed successfully, a green ok appeared, but the phone would not turn on anymore, so place your bets on whether it will turn on or not. By the way, before updating the firmware, fully charge the phone, because I had problems. I once had the P780 charged to 10% and it was either detected by the computer or not, so better charge your phones to 100% and I think you'll have less problems.
Now for the second attempt, it vibrates... Everything seems to be fine, the phone always takes a long time to turn on for the first time, so we’ll wait a little.

Well, the Lenovo P780 turned on, then we are offered a choice of language - Russian, connection - click next, we can immediately set the volume. I personally really like the convenient firmware. Although many people don’t like it, they don’t like VIBE itself, but they say that you can get used to it. Well, this is VIBE here, I think for many it will not be familiar, but this can all easily change.

As you can see, everything worked out for me, everything works, I took the firmware for old phones, changed the bootloader, and everything started for me, everything worked even on the Lenovo P780 2014 phone. In the same way, you can take any old firmware that you really like, change its bootloader and load it into your 2014 phone. At the same time, everything in it is translated normally, in normal Russian. I really like the animation of the cylinder. The animation is scrolling, the cube is not very beautiful, but for some reason the cylinder is more nimble and pleasant.
