What to do if the message formatting data appears. Full Wipe - detailed description of the process
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 ( 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 when last time 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 the charger is 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 observe the display backlight turning on, and then endless loading(constantly overflows inscription ANDROID), 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 Chinese manufacturer. I highly recommend reading the instructions for hard reset'u on various devices. I will briefly describe 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-language video instructions for hard reset for Acer tablet 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 the mode stock recovery(if you are wondering what it is), there is nothing bad about 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 with an open belly/belly, but without exclamation point. 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.

For better understanding(but not necessarily) what is erased with this or that wipe/format can be found in the article:.

As a rule, “experienced” people are called in terms familiar to them. this procedure: do "wipe", "factory reset", "clean dalvik". The advice of experts (with or without quotes) is not always obvious and understandable to the user, and even more so to the inexperienced.

Wipe on Android from the Recovery menu
Wipe can be performed from both standard Recovery and custom one. Executing Wipe from the Recovery menu is more flexible in its capabilities than from the settings menu.
Executing Wipe from standard Recovery
IN standard Recovery You can perform 2 types of factory reset.

About the subtleties of performing Wipe on Android
Many people are faced with the question of when to perform wipe? Before the firmware or after? It is better to do this before installing the firmware, since many firmwares may have a built-in automatic reboot function after installing the firmware! If the firmware contains files that are uploaded to the data section, then it’s worth checking how the system behaves; if it boots, it’s good; if not, then run wipe data.
About the subtleties of performing Wipe on Android 2
Based on personal observations, I noticed the following feature: in the popular custom firmware CyanogenMod (LinageOS) there is a script that is executed during installation from the recovery menu. This script first backups system files ( system section) before flashing and restores after. Because of this script, errors can sometimes arise and wander from firmware to the next firmware. Therefore, if you use LinageOS firmware or you know that the updater-script contains a script that performs this backup, then it is better to make a format system before updating the firmware.
That's all, stay with the site!
On smartphones and tablets Android based there is a special Recovery Mode menu or simply . This is a special device boot mode, thanks to which you can reset all settings or, say, install new firmware to the device.
This is what Recovery Mode looks like on a Samsung smartphone:
To call this menu, you need to do a number of actions along with rebooting the smartphone. For example, on Samsung Galaxy S3 process is as follows:
- Turn off your smartphone.
- Press the volume up button, Home button and the power key of the smartphone at the same time.
- Release the buttons as soon as you see the recovery menu logo.
Please note that the image shown above is the stock Recovery Mode. There are also custom versions of the menu, they are installed by the user independently and can have a completely different look.
There are several items in the recovery menu that raise questions among users. Let's talk about some of them.
Wipe data/factory reset
When using Wipe data/factory reset, all applications and data are deleted (cache, Accounts), excluding data such as music, photos, videos. It is usually used if any errors occur while using the device, or the smartphone or tablet starts to slow down due to some application, or the user wants to return the device to its original state and reset the settings.
Wipe cache partition
Wipe cache partition- This is clearing the cache partition. This area stores temporary files that remain after running applications or updates. It is used if the smartphone works slowly or starts to slow down. In this case, applications are not deleted, unlike the previous case.
Other types of recovery menu
Some recovery menus have additional items. For example, in Recovery Mode on Xiaomi devices can choose additional modes cleaning, like, say, Wipe SD Card - deleting data from a memory card. And the menu look is completely different.
