The green android robot no longer greets you when you turn it on, but lies accompanied by an exclamation mark.
So, if you observe this picture, the android is lying with exclamation point, then you can be congratulated, you have made your first unsuccessful experiment in interfering with the software of your device. What is it, and most importantly, what to do with it and how to restore the viability of the device? The search for answers to these questions must begin, first of all, by finding out the reason that led to this condition.
If you installed an incorrect program for Android, then after rebooting it will definitely please you with an image with an exclamation mark. There is only one way out - to do a hardware reset by selecting Wipe data/factory reset in the engineering menu.
Login engineering menu, if your Android is different on different Android smartphones, but the combination of the home, power and volume down keys is recognized as standard. On devices with touch button Home is usually a combination of the power and volume down keys. The key combination suitable for your device must be pressed with your fingers and held until the service menu appears on the screen.
After the inscriptions appear, you must select the appropriate item by moving up and down using the volume rockers. After selecting this item, several lines will appear on the device screen asking whether you agree to delete all data from your device. After selecting the line yes will occur complete cleaning device memory. The next step, if the device does not reboot automatically, select rebootsystemnow, which means rebooting the system. If after these operations your device has restored its functionality, then we can congratulate you. The only negative this method is the loss of all information - including contacts, SMS, photos and downloaded applications.
However, if you regularly synchronize your phone with Google and remember your login and password account, then your losses will be insignificant.
If the above method did not help, then a complete replacement is required. software. There are two ways - the first is flashing the device using a USB cable and a computer, but it will only help you if the “usb debugging” function has been enabled in the device settings. The second way is to update the software using a flash card through the engineering menu. Both methods are very risky and the slightest violation of the instructions will lead to the complete destruction of the device. At this stage, you should think about whether to try to restore the device yourself or trust the professionals.
If you nevertheless decide to flash an Android with an exclamation mark yourself, then you should carefully study all the information provided on the Internet on this issue. Certain types of Android devices have significant differences and features regarding software changes. If we briefly and generally describe this process, it looks like this: you find the firmware file on the Internet, download it, simultaneously studying reviews about this version and installation information. After this, you decide on the method of performing the Android recovery procedure with an exclamation mark.
If you choose the method using usb cable, then unpack the firmware files into the root directory of drive C on the computer, install drivers for your smartphone if necessary, turn off the phone, use the key combination (usually the combination power+volume up) to enter the phone into firmware mode, connect the device via a USB cable and follow the further instructions of the program . At the end of the process, be sure to hard reset your device to default settings using the recovery menu.
If you decide to resort to the second method and restore the software using the device itself and a flash card, then the steps are as follows - upload the firmware file to the root directory, insert the flash card into the phone and launch it in recovery mode. After the engineering menu appears, select the recovery option using SD and wait. After finishing, you also need to reset your Android device.
What to do if Android has an exclamation mark? In this article we will look at the main causes of device malfunction and ways to solve it.
First version operating system Android appeared in 2008. Availability large quantity functions, ease of use and low price compared to analogues, made it accessible to a wide range of users. It is not surprising that issues related to long-term and uninterrupted operation of devices with this operating system are very relevant.
An icon on the screen in the form of an android with an exclamation mark indicates a malfunction in the device software. It may be associated either with the installation of an unlicensed program, or with a virus infection.

Typically, a user may encounter such a problem when turning on (rebooting) a smartphone or tablet. If this happened to you, what can you do?
The first thing they offer in such cases is. To do this, you need to turn off the device, if necessary, charge it to 100% and turn it on in the developer menu mode. Since the key combination depends on the smartphone or tablet model, we recommend that you refer to the instructions. In the standard case, this can be done by simultaneously holding down the power, volume down and (or) Home buttons.
In some cases, after this action, the smartphone can return the factory settings automatically, but sometimes this must be done manually. Remember that in this state only the buttons work (you won’t be able to use the sensor). To move up and down menu items, you will have to use the volume keys. In the list, you need to select the “Wipe data/Factory reset” position with the Power or Home button, which means “delete data/reset settings” and confirm your choice in the next window that opens.
Photo: Hard reset menu The main disadvantage of this action is that it will remove everything from your device that is not factory settings. And these are contacts, messages, photos, audio and video recordings and programs you installed. Therefore, if you do not want the safety of your data to depend entirely on one electronic device, make backups in advance.
If you are not sure that you can cope with this task yourself, it is better to contact a specialist, because any mistake can lead to catastrophic consequences.
If the “USB debugging” function is enabled in the Android settings, you can reflash the device.

Photo: USB debugging Unpack the already downloaded folder with the program on drive C. Check for downloaded drivers for your smartphone and install if they are not there. Turn off the device, use a key combination to enter it into firmware mode and use a cord to connect it to the computer. Next, follow the instructions of the program.
If you have not enabled the ability to debug your smartphone via USB wire, consider another option to reinstall the software using the device itself and a flash card. To do this, you will have to return to the previously described menu again, selecting the option to restore using SD.

Let's summarize: Android lies with an exclamation mark - this is not an easy problem, but it can be solved. If you don't want to deal with it often, be careful about what you download to your device. Be sure to install.
You can fix the problem either yourself or with the help of a specialist by resetting the settings or reinstalling the software.
Dear readers! If you have any questions or comments on the topic of the article, please leave them below.
In this case, charge it for a couple of hours. Then, hold the off button for 15 seconds (or press reset). Wait about 15 minutes for the tablet body to cool down (the back cover may get warm when charging). Now try turning it on (3-5 seconds on button) and wait 2 minutes.
Please accept my condolences, because if you are reading this article, it means your Android tablet has stopped turning on. The reasons may be “hardware” or “software”. The first reason is the physical inability to turn on due to damage to the battery, board, cables. The second is that someone screwed up the operating system on the tablet, and due to the fact that it got up crookedly after, or some freshly installed program turned out to be extremely incompetent, the device cannot “start up”.
The tablet won't turn on at all
1. Remember the last time you charged your electronic friend. One of the most common reasons is a tablet. fully discharged. In this case, even if you put it on charge, it will take some time (sometimes up to 10 minutes) before the tablet has enough power to turn on. Sit next to the patient, and after a one-minute break, press the power button for a long time until the screen lights up. And yes, you must be sure that Charger working. If there are no changes, check on another device to see if the charger is working, or change it. If you are interested, then you need another article.
2. Remember, maybe you gave a tablet to a child? Perhaps the baby slammed the screen as hard as he could into the corner of the crib and damaged the display. In this case, the tablet itself may work, but the screen will have to be replaced. The same situation occurs if the tablet lands from a height of one and a half meters on asphalt or a tiled floor. There is little you can do to help him on your own; you can only sympathize with the poor fellow. Typically, a damaged screen is indicated by visible mechanical defects, or the absence of an image when turned on (instead, only the backlight may be visible, and even then not always).
3. The tablet did not fall or hit, but there is no image? Unlikely, but still: perhaps the video adapter has failed.
If your tablet is still under warranty, then it’s stupid to fix it yourself. Take it to the service center and don’t worry. Of course, you can download the diagrams on the Internet and try to fix it yourself or give it to a friend, but it’s better not to do this.
The tablet only turns on halfway
It's all my fault software glitch, and only him. In such cases, we see the display backlight turn on, and then endless loading (ANDROID is constantly flashing), or we see an image with a broken green robot.
This may be a consequence:
1. Incorrectly installed or malfunctioning games, programs, launchers.
2. Forcefully terminated system processes, ensuring the stability of the operating system. This can easily happen if you “killed” system process through some kind of task manager (or dispatcher), or third party program“battery saver”. Believe me, this happened to me once.
What can be done in such a situation?
There is a chance to “revive” the tablet by resetting its settings to factory settings. This is done using Hard Reset, and it is better to google how it is done specifically for your model. Especially if you have a tablet from a Chinese manufacturer. I highly recommend that you read the instructions for hard reset on various devices. I will briefly describe the general principle; most likely you will need to do the same:
- Turn off the tablet
- We take out the memory card and SIM card (just in case)
- Press and hold the volume down key ( and for some it is a decrease!) and the power button for about 10 seconds, the time is also not the same for all tablets.
- The tablet should vibrate
- A menu appears. Use the volume and power keys to select the item Settings. Further - Format System
- Choose Reset Android, tablet reboot
- All data and settings that were in the device’s memory will be erased and returned to the factory settings.
- Don't be alarmed if you don't succeed the first time, you usually succeed the second time :)
If this instruction didn’t help, try using the advice on a hard reset from commentator Dima in the article, you don’t have to look for the advice itself in the comments, I added it to the article. It also helps to bring the device back to life. How to restore the tablet after unsuccessful firmware written
Just in case, English video instructions for a hard reset for a tablet Acer Iconia Tab A500:
If a lying Android appears with a red exclamation mark
In many, I noticed in the comments, everything ends like in the picture, or something like that:
This is a stock recovery mode (if you're wondering what that is), and there's nothing wrong with it and you shouldn't be afraid of it. Moreover, you can - ClockWorkMod Recovery. If you see it, it means it works - and that’s good. You got into it because you entered the wrong combination for a hard reset, and I warned you that it is not the same for all tablets. In this situation, you can press and hold the power button until the tablet turns off and try again, or just wait 5 minutes until it turns off and repeat the process. Try again, as a last resort you can just reflash.
Fastboot mode
Sometimes, when trying to find the right combination, users end up in Fastboot mode. In such a situation, we see the “Android” lying down with an open belly/belly, but without an exclamation mark. An example of such a menu for Nexus 7 (2013) in the photo:
If you get here, then use the volume buttons to select the item Restart bootloader and press the power button to confirm your selection. Perhaps this will help you boot up a tablet that has not turned on before.
In general, it is useless to advise anything specific here, since each model has its own paddocks. For some tablet models, you just need to press the “Home” button if a lying Android with an open belly appears - and a menu will appear in which you can select to reset the settings. And for some, press volume up and down at the same time. And wait.
Usually, many owners Android smartphones and tablets are eagerly awaiting the arrival of new versions of the operating system. And this is not surprising, because they bring us not only new functions and capabilities, but also solutions to current problems, as well as corrections of minor errors.
But sometimes the opposite happens - a long-awaited update brings us new problems, and sometimes these problems can be quite serious. Take, for example, a tablet Google Nexus 9, for which it was recently released Android update up to version 5.0.2 .
Some owners of these tablets complain that after installing it, the tablet stops booting and goes into a cyclic reboot.
If you are one of the victims of this update, then we have good news for you: you can easily restore the functionality of your tablet after installing the ill-fated update on it.
To do this, you need to clear the operating system cache. You can do this from the factory recovery of your NEXUS (or from an alternative recovery such as Clockworkmod or TWRP - if you installed the update on your tablet manually from a file).
The procedure for clearing the cache from stock recovery is quite simple:
1. Turn off the tablet completely.
2. Turn it on by pressing and holding the Power and Volume Down buttons at the same time.
3. The tablet will boot into bootloader mode.
4. Press the volume buttons to select the “Recovery” option and confirm your choice by pressing the power button.
5. After the tablet reboots and a green robot appears on the screen, press the power button, and then without releasing it, press the volume up button.
6. You are in recovery. Now, by pressing the volume buttons, go to the “wipe cashe partition” item, after which, start clearing the cache by pressing the power button.
7. Reboot the tablet: “reboot system now”
That's it, now your tablet should start successfully new version Android.
If this does not happen, then we have some not very good news for you: you will have to say goodbye to all the personal data and applications you installed on your tablet. To restore system functionality in this case, you will have to reset to factory settings.
This can be done from bootloader mode: follow steps 1-3 of the above instructions, and in step 4, select the “Factory Reset” option.
If an android with an exclamation mark appears on the screen, this means that an unsuccessful experiment was carried out with the device’s software. This may have happened due to the installation of an unlicensed program or after switching from original firmware to custom.
From the article you will learn
Hard reset
This action is carried out in the device’s engineering menu and allows you to return the smartphone or tablet to its original settings, which is very useful when the android lies with an exclamation mark. A special engineering menu is called up by pressing certain buttons, but there are some difficulties here. Models different manufacturers The key combinations are different. There is a certain sequence in calling the engineering menu.
The device must be turned off. It is best if the battery is fully charged. For most gadgets, the following combinations of buttons to open the menu are suitable:
- The Volume Down key (or Volume Up key) is pressed and held together with the Power button.
- Both sound control keys are pressed and held, and then the power key is pressed.
- 3 buttons are held simultaneously: main screen, volume up and power.

On smartphones and tablets manufactured by Samsung, the engineering menu is entered by pressing 3 buttons simultaneously: the gadget's main screen key, the volume up key and the power button. Resetting to the original settings is done using the Wipe data/Factory reset item and then rebooting.
HTC devices, when Android with a red exclamation mark appears on the display, can be brought back to life by pressing and holding the power and sound control buttons. When Warning appears on the display, you can release everything and press the volume up key. On some models, hold down the volume button and press the power key until an android robot appears on the screen. After it appears, you can release the buttons and press the volume down key again.

Device firmware
If a hard reset does not help, a complete software replacement is required. But there is a formality here: the firmware will only help if the “USB Debugging” function has been enabled in the device settings. This method is quite risky and the slightest violation of the instructions can lead to damage to the device.
Here it’s worth thinking about: should you try to restore the device yourself or trust the professionals? But if you decide to flash the gadget yourself, you should carefully study all the available information on this issue. Models from different manufacturers have significant differences and features regarding software changes.
In general, the process of replacing software looks like this: download the file with the firmware, study installation information, read reviews about this firmware version. Next, the file should be unpacked into the root directory of drive C and, if necessary, install drivers for the gadget. After this, the device must be turned off and using a key combination (usually a combination of the power button and volume up) switched to firmware mode. Then you should connect the device via cable to the computer and follow further instructions of the program. At the end of the process, you must perform a hard reset using the engineering menu.
What should I do after restoring the device?
The main disadvantage of resetting the settings is the loss of information stored in the gadget: photos, videos, applications, music, contacts, etc. Therefore, it is best to regularly synchronize your smartphone or tablet with Google.
This gives very great opportunities. For example, if you take a browser, synchronizing with it will allow you to access saved passwords, bookmarks and other useful things in any gadgets.
Thus, synchronization with a Google account is necessary for the convenience of using various services and applications. You can also sync contacts in mobile phone with Google contacts.
If synchronization with Google has not been carried out, then it is better to do it immediately after the gadget is restored to functionality. First of all, you need to add a Google account. If you already have a registered account, you must enter your address and password. Email and click "OK". After this you will be asked to backup and restoration, which will create backup copy data of this device in Google account. By pressing the “OK” key you should confirm the synchronization and wait a few minutes.
After completing the process, you need to click on the email address, where you will see that all services have been updated. You will receive a notification that new messages have been received and that photos have been synchronized, Google browser Chrome, Google Drive, Calendar and Contacts. It is better to synchronize your tablet or smartphone with Google as often as possible.
