Is there any possibility to format the phone so it come with every setting stock ?

Turn phone off. Remove SIM and SD card (if you have one)

Hold down the volume up button and the home button and then press the power button, pressing all three buttons until you see the phone turning on. Then release the buttons.

This enters the recovery mode. Now you see a list of options. Navigate the list by using the volume button to go up and down the list, and the home button to select an option.

Choose the factory reset option. The phone reboots and is reset to factory default.

Backup anything important that you may want to keep before doing this!
