Flash Android 7.0 Nougat on your AT&T Galaxy S7

You know that I have been closely following the progress of the latest Android software upgrade, Android 7.0 Nougat, for the Samsung Galaxy line of devices expected to receive it and I am perfectly aware of the fact that many of you want to flash Android 7.0 Nougat on your AT&T Galaxy S7. Well, this is now possible thanks to an XDA member, so be sure that I am here with more details!

There is no secret about the fact that AT&T has the habit of not making full firmwares available, but as it happens, some users manage to capture the OTA zips and share them at forums. This time, Jimmyvb98 is the one that we have to be thankful to as he has shared these OTA zips and by flashing them in consecutive order, you can finally enjoy the official Nougat on your own AT&T Galaxy S7.

Things aren’t quite as you are used to this time, therefore be very careful and ask me in case of having any doubts. First of all, make sure to verify your version, so go to Settings> About device> Software info and check your phone’s current firmware version. If your Galaxy S7’s firmware version is G930AUCU2APD1, you need to download all 6 files (from v2 to v7) found below. Anyway, if your Samsung phone is currently on G930AUCU2APG1, for example, start downloading from v5 onwards. You have to install the files in the same order as they appear in the list.

Even more, you have to go to Settings> Personal> Lockscreen and security > Find my mobile and turn off Reactivation Lock. Then, enter into Settings> Developer options and, as always, enable USB debugging.

You must also take a backup of your important data and verify the battery percentage of your AT&T Galaxy S7. And no less important, this time you have to go to Settings> Applications if you have disabled some system apps and enable them or this OTA installation may not succeed.

    This guide looks awesome! Before I start, can I get root access under Nougat? If I have root already, will I lose it after upgrading here? Let me know, can’t wait to try!

    Additional comment to add – on Step 4 – the link given is for G935 (the Edge), not the G930 (s7 regular) – won’t flash in Odin :(
