general information
Preface
For proper interaction between your electronic friend and your personal computer, you will have to install a driver. Definition of driver:
Spoiler
Driver (English driver, plural drivers) is a set of files with which software or an operating system gains access to the hardware of a certain device (text editor - printer, skype - web camera, paint - scanner). Typically, operating systems come with drivers for key hardware components, without which the system cannot work (video adapter, hard drive, keyboard...). However, some devices (such as a video card or printer) may require special drivers, usually provided by the device manufacturer.
Postulate one
Due to the specifics of my hobby, I had to interact with all Lenovo devices supplied to the Russian market. Drivers for Lenovo smartphones built on the MTK processor platform are identical, with the exception of some instances, therefore, the drivers and recommendations for installing them laid out in this manual are universal and will suit everyone.
Postulate two
Drivers for Lenovo smartphones are divided into 2 types:
- Work mode drivers include:
USB storage mode. No driver is required - it is built into the OS itself. In simple words, connection is like a flash drive. By connecting your smartphone to a PC as a USB drive, you disconnect your smartphone's SD card from the smartphone, transferring it to the control of the PC.
MTP mode (media device). No driver is required - it is built into the OS itself. A feature of Windows XP is that for this mode to work correctly, you must install Windows Media Player version 11 from Microsoft website and run it at least once. In this mode Simultaneous access to the SD card is carried out from both the PC and the smartphone. MTP Abbreviation Definition:Spoiler
Media Transfer Protocol (MTP) is a PTP-based hardware-independent protocol developed by Microsoft for connecting digital players to a computer. Unlike the USB disk protocol, MTP operates not on sectors, but on files. Thus, the player, connected as a flash drive, is completely trusted by the computer; connected via MTP - is independently responsible for the storage and integrity of data and, thus, can play some tracks simultaneously while recording others.
Camera mode (PTP). No driver is required - it is built into the OS itself. Same as MTP, but only the DCIM folder is visible. Used to view photos and videos from the device memory.
USB debugging. Intended for development purposes. With its help, you can copy data from a PC to a mobile device and vice versa, install applications on the device, view log data, take log files of the smartphone’s operation, etc. - Special mode driver. Used only a few times in the life of a smartphone - to install firmware through the utility . The smartphone enters this mode when it is connected to the PC while it is turned off.
Postulate three
- To successfully install drivers you must:
- Not all drivers are signed with Microsoft certificates, so these OSes may ask questions during the installation process. We don’t pay attention and click the “Install anyway” button .
- To unpack archives with drivers, use an archiver 7zip the latest version of which can be downloaded from the developer’s website 7-zip.org

When starting to flash the firmware for an Android device, you first need to take care of the preparatory procedures. This will allow you to carry out the process of recording the necessary software components into the device as quickly and efficiently as possible, and will also make it possible to avoid errors that will turn the procedure into torture. One of the most important steps when working with Android device software through specialized Windows applications is installing firmware drivers.
Before you begin installing software components in Windows, you need to prepare your Android device. In many cases, the capabilities of Android Debug Bridge (ADB) are used for firmware, at least partially or at a certain stage. This tool can work with an Android device only if the latter mode is activated "USB Debugging". Almost all device manufacturers and developers of various variations of the Android OS initially block this opportunity for users. That is, after the first launch of the device "USB Debugging" disabled by default. We turn on the mode by following the following path.
Preparing Windows
As for Windows OS, its preparation before starting the firmware process involves disabling driver digital signature verification. To avoid possible problems, it is necessary to carry out the operations described in the article:
Installing drivers for Android devices of famous brands
The first thing you need to do when searching for a driver for Android firmware is to go to the official website of the device manufacturer. Well-known manufacturers in most cases provide the ability to download drivers either as a separate package or as part of proprietary software designed to service brand devices.
For installation, if the necessary files are available on the manufacturer’s official website, it is enough to download the auto-installer or installer of the program for servicing Android devices of the brand, launch it and follow the prompts in the application windows.
Android developers have decided to make it somewhat easier for users to find web pages intended for downloading files necessary for flashing devices. On the official website of the Android Studio developer toolkit there is a page containing a table that makes it easy to navigate to the official software download site of many well-known brands.
Owners of devices manufactured by well-known brands often have another opportunity to install the necessary system components, which many people forget about. This is a virtual CD integrated into the Android system that contains everything you need.
To use this solution, you need to connect the device to the USB port of your computer and select the item in the Android USB connection settings "Built-in CD-ROM". After connecting the Android device in this mode, a virtual disk drive appears in Windows, which also contains the drivers necessary for flashing the firmware.
Installing ADB, Fastboot, Bootloader drivers
In many cases, to install software components that ensure pairing and interaction with Windows of the device in ADB, Fastboot, Bootloader modes, it is enough to resort to the package provided by Android developers on the official page of the Android Studio toolkit.
If the above does not work, go to the device manufacturer’s website and download the package of files from there.
Installing VCOM drivers for Mediatek devices
Devices built on the MTK platform are notable for the fact that their firmware is in most cases carried out using the SP Flash Tool application, and this in turn implies pre-installation Preloader USB VCOM Driver.
There is an auto-installer for MTK drivers. Initially, we try to solve the pairing problem using it.
You just need to download the installer file and run it. The application is essentially a console script and all actions to add the necessary components to the system are carried out automatically.
If the auto-installer method does not work, you will have to install MediaTek PreLoader USB VCOM Port manually. To do this, we perform the following steps.
Installing drivers for firmware Qualcomm devices
In general, when pairing an Android device, which is based on the Qualcomm hardware platform, with a PC there are no particular difficulties. Unfortunately, Qualcomm does not provide the ability to download software from its own official website, but recommends that you refer to resources on OEM websites.
For almost all devices, this is what you should do. For convenience and speed up the search for links to device manufacturers’ download pages, you can use the one compiled by Android developers.
Instructions for pairing Android devices on the Intel platform with a PC
Android devices based on the Intel hardware platform, just like devices with other processors, may require firmware using special utilities, so installing ADB-, MTP-, PTP-, RNDIS-, CDC Serial-USB profile drivers before starting manipulations – a necessary condition for the correct execution of the procedure.
The search for the necessary files for Android devices with an Intel processor is carried out on the websites of OEM manufacturers. For a more convenient search for the download page, you can again use the table from the Android developers, which they kindly posted on the official Android Studio website.
It is worth noting that in most cases, to install the components necessary for manipulating Intel devices running Android, it is enough to turn to the solution offered by the hardware platform manufacturer.
As you can see, installing drivers for Android firmware is not as complicated as it might seem. The user actually experiences the greatest difficulties when searching for the required package of files. Three simple tips on how to avoid problems or resolve errors when pairing Android and Windows.
- If you can’t find a working driver, you can use the method described in the article:
- Quite often, when installing components necessary for flashing a device released under a little-known brand, the situation is “saved” by a special program - DriverPack. Instructions for working with this application, which in many cases allows you to successfully add the necessary files to the system, are presented at the following link:
- Another common problem is installing the wrong version of drivers, as well as conflicting system components. In order to avoid such a situation, it is necessary to remove “unnecessary” hardware components in the system. To facilitate the process of detecting and removing USB devices, we use the USBDeview program.
One of the most common problems associated with the firmware of MTK-based devices is incorrect driver installation. Let's imagine a situation that you have downloaded a program called SP_flash_tool and want to flash your smartphone. Having specified the firmware files and the scatter file, you click the Download or Start button, connect the phone to the computer, but the program does not see the phone and does not react in any way to connecting the device. In this case, the first thing you need to do is check whether the drivers were installed correctly.
There are 3 main ways to install them.
It is worth noting that sometimes on a Windows 10 system it is not necessary to install drivers at all for the SP_flashtool program to work properly. They can be preinstalled in it.
Automatic driver installation
If automatic installation via the .exe or .bat installer did not help, or there is no .exe or .bat file in the driver folder and the SP_Flash_tool program continues to ignore your phone, then the method of manually installing the MTK driver can help.

A common problem when flashing MTK-based devices is incorrect installation of USB drivers. You are going to flash your smartphone using SP_flash_tool, connect your device to your computer, but it simply does not see your device and does not react in any way to its connection. If this is a problem, you need to check that the drivers are installed correctly. We'll cover three main installation methods.
In Windows 10, installing the MTK driver is not always required for SP_flashtool to work correctly; most often it is preinstalled there.
Method 1: Automatic driver installation
If automatic installation of the MTK driver via the .exe or .bat installer did not help, or there is no .exe or .bat file in the driver folder and SP_Flash_tool continues to ignore your smartphone, then try the manual method of installing the MTK driver.
