Install Android Nougat on AT&T Galaxy S6/S6 Edge (SM-G920A/G925A)

Rakesh | | ROMs/ Samsung

Almost all variants of the Galaxy S7 have already received the Nougat update and now the Korean giant seems to have turned its eye to our good old Galaxy S6. While the international models of the phone got the Nougat OTA more than a week ago, the users of the AT&T variant have not started receiving it.

Since the full Android Nougat firmware for the device is not available anywhere, you will have to flash the OTA zip packages depending on your current firmware version in incremental order. In this tutorial, we’ll see how we can install Android Nougat on s6.

If you have not been able to get the official Nougat OTA on your AT&T Galaxy S6 (SM-G920A) or S6 Edge (SM-G925A), you can update your phone’s software by installing the OTA zips provided below.

Disclaimer

Please note that your AT&T Galaxy S6/S6 must be fully stock to install the OTA. Though we have taken utmost care in laying out the installation steps, a successful installation depends on how you follow them. Proceed at your own responsibility and don’t go ahead if you don’t understand at all what you are going to do.

Getting Prepared

Before you proceed, here’re a few preparations you need to make so that things go smoothly for you.

  • Backup all your data and apps using Smart Switch as a precaution.
  • Go to Settings> Personal> Lockscreen and security> Find my mobile and turn off Reactivation Lock.
  • Go to Settings> Developer options and enable USB debugging (this is just as a precaution).
  • If you have disabled any system apps, please enable them from Settings> Applications or the OTA file installation might fail.
  • Charge your Galaxy S6 so that it has 60% battery level at least.
