When you reset to factory settings, the changes made during the entire operating time of the phone will be rolled back. Please be aware that this will delete some data, such as entries in the call log, contacts, installed programs, but will save the entries on the microSD card (photos, music files, etc.). Therefore, before the operation, it is necessary to save a backup copy (backup) of the data on the phone.
Instructions
Step 1
Make a backup. The quickest method to do this is to connect your phone to your computer and sync the data on it with your account on the Google, Microsoft My Phone, or Exchange ActiveSync websites. You can also save your data to Outlook via ActiveSync. Another method is to use Spb Backup, Pim Backup or Sprite Backup to save data.
Step 2
Use the phone menu to return to factory settings. Press the following buttons in sequence: "Menu", "Settings", "Privacy", "Reset to factory settings", "Reset phone settings", "Erase all". If you need to enter the phone code, you need to take it in the user manual. The system then rolls back the changes and reboots.
Step 3
The second method, which allows you to restore the factory settings, is performed using the phone buttons. Switch off the phone and press two buttons simultaneously: the call key and the end call key. While holding them, press the power key and hold all three buttons until a window with the question "Reset everything to factory settings?" Appears. Press the call key to accept or the end call key to cancel.
Step 4
The next method is performed from the Recovery menu. To enter this menu, turn off your phone and simultaneously press the "Volume Up" button and the "Home" button (the middle button below the screen), and then the power key. After entering the recovery menu, select wipe data / factory reset, then press enter (that is, the call key). The mode when working in the recovery menu should be three-button.
Step 5
Another way to do a factory reset is with a service code. The service code itself can be found at https://vsekodi.ru/index.php/samsung. This resets all settings, even clears the internal memory card, so use this method with caution.
Step 6
After completing the operation, you can restore the data from the backup and customize the phone to your liking. Whichever method you choose, remember that resetting your phone to factory settings is a dangerous operation that can lead to data loss or even damage to your phone, so use it only in special cases.
