There are situations when the rollback of the device to the factory settings is the best solution to the problem. There are several ways to perform a reset: through the reset device itself or using a computer. .
Why reset
Hard Reset - Rollback operating system to default values. When performing a reset, all files and third-party applications are deleted from the device’s memory, and all settings accept factory settings. Resetting the system, you will get a clean device, that is, it will be in the form in which it was in the store.
A reset can be useful in the following situations:
- the device started to freeze due to a large number installed programs;
- the system started to hang due to overloaded memory;
- in file system many files left from remote applicationswhich occupy free space;
- the device is sold, so you need to delete all personal information from it;
- need to reset the password, because it was forgotten.
As a result, it turns out that the reset must be performed when it is necessary to format the device.
How to save data
Since when you reset the system, all data (videos, photos, music, pictures, books and other elements) from the device is erased, it is strongly recommended that you think over how to save all the important information in advance. The easiest way is to transfer all important files to a memory card or computer. When resetting, the items stored on the SD card, even if it is inserted into the device, are not deleted, but just in case for the duration of the operation, it is better to remove the memory card.
Another way is to create a backup copy in which all files will be stored. After performing a reset, you can restore the system from a previously created backup, and all items and applications will be returned. The positive side of this method is that you will not lose not only files, but also applications. The negative side - if the reset is carried out in order to clean the device from idle files, then when restoring from the backup, the files you wanted to get rid of will also be restored.
Copying is done using google service and only via Wi-Fi, as the amount of information is too large to be downloaded via mobile Internet. Go to the device’s settings, open the “Restore and reset” tab and make sure that the automatic backup function is enabled. The copy will be tied to your Google account, you can recover from it after you perform a reset. The device itself will offer you to use the found copy.

Via computer
This method will help you enter the recovery menu if, for some reason, the previous method failed to do this. Connect the device to the computer using the USB-adapter and in the connection type specify “Charging only”. Download the archive with the ADB program and unzip it to any folder whose path does not contain Russian letters. In the resulting folder, create a file called devices.cmd, where cmd is its extension, and write three commands into it:

Your Android device will automatically be transferred to the recovery menu, and further actions that need to be performed to reset are described above in the “Via the recovery menu” sub-item.

If you reset the device in order to remove the password that you forgot from it, and after the procedure is completed, the system still asks you to enter it, that is, two ways out of this situation. First, enter the wrong password five times, a message appears on the screen stating that the device is locked for 30 seconds, as well as the “Forgot your password?” Button. Click on the button that appears, you will be asked to log into your Google account, which was previously tied to this phone or tablet. If you log in desired account, then get the opportunity to reset the existing password.

The second option is to reset the password using ADB. How to install this program is described above in the sub-item “Via computer”. When you are done with the installation, run the command prompt as administrator and execute the following options in it:

rm /data/system/gesture.key.
How to recover data after a reset
It was previously described that in order to save data, you must first create backup files or transfer all important items to another medium. If you did not do this, but at the same time reset the device, then, most likely, it will not work to restore the lost information. But it’s worth a try: get root-rights on the device, and download a program on your computer designed to recover deleted files on Android. For example, you can use EASEUS Mobisaver for Android Free.
