How to Install Stock Firmware on Samsung Galaxy S7

As you know, there is no OTA that can be received if your Galaxy S7 is rooted or unlocked. So, everything should normally be kept official if you want to get new updates by air or else you will have to revoke root access and reinstall the stock Android firmware on your phone.

You probably know that you can choose to flash the official Android update manually and this is exactly the operation that I want to tell you more about.

This guide will allow you to easily restore your Galaxy S7 back to factory settings, just like the day you bought it. To be more precise, it will remove any sign of root, custom ROMs, or modding on your phone. Even if you’re not rooted, but planning on selling your phone or sending it back to the carrier or Samsung, this tutorial is the best as it will wipe any personal information you may have on your Galaxy S7.

For being able to perform it, you must use a computer running on Windows on which you will install Odin at a later time, the small tool developed by Samsung and used on update types of operations. Also, on your phone you have to access Menu – Settings – About phone from where you have to tap several times on Built Number, until you become a developer. Up next, you must check the USB Debugging option, a feature that can be found under Menu – Settings – Developer options. And you should also think of disabling the security protection from your computer before doing anything else as it might stop the procedure or make you a hard time while performing it.

This guide will only take no more than a few minutes and your Galaxy S7 will be back to its initial days with no problem and all user information removed, so what are you waiting for?
