Special software

This can be done using the Samsung Kies program or the popular Odin. In the case of the latter, you can use both official firmware Samsung, and firmware from other developers. They are often more convenient and give more opportunities for the phone, but at the same time the factory warranty is lost. For this reason, the implementation of any instructions on how to reflash the Android phone unofficially is permissible only after the end of the warranty period.
