Below is a step-by-step guide for installing on how to install nougat on Galaxy S7 Active SM-G891 update over-the-air (OTA) on your AT&T-powered Galaxy S7 Active SM-G891A.

The Samsung Galaxy S7 Active, a device under AT&T’s lineup, is now being updated to Android 7.0 Nougat. This update has already been released for non-branded models of the Galaxy S7 and is now reaching carrier-branded variants like the Galaxy S7 and Galaxy S7 Edge. You can successfully update your waterproof smartphone to the newest Android version, and you are on the verge of doing just that.

How to Install Nougat on Galaxy S7 Active SM-G891A – Overview

Updating your AT&T S7 Active to Nougat involves flashing a set of files through the stock recovery system on your phone. The number of required files depends on your current firmware version. This tutorial is safe to follow and carries no risk, ensuring your phone maintains its stock and official status. It is crucial to carefully adhere to the provided instructions during the process.

To update your phone, first, download the appropriate files based on your device’s current firmware version. For example, if your phone runs on G891AUCU1APE7, download and flash all six files sequentially. Alternatively, for G891AUCS2APL1, only the fifth file needs to be downloaded and flashed. Following this pattern, select and flash the necessary files to transition to the latest firmware version efficiently.

Download Phone Update Files

  1. SS-G891AUCU1APE7-to-U1APG7-UP: Download (G891AUCU1APE7 -> G891AUCU1APG7)
  2. SS-G891AUCU1APG7-to-S1APH1-UP: Download (G891AUCU1APG7 -> G891AUCS1APH1)
  3. SS-G891AUCS1APH1-to-S2API2: Download (G891AUCS1APH1 -> G891AUCS2API2)

  6. SS-G891AUCS2APL1-to-U2BPL4-UP: Download (G891AUCS2APL1 -> G891AUCU2BPL4)

Navigate to your phone’s settings, then access the “About Device” section and select “Software Info” to view your phone’s build number.

  1. If your phone’s build number is PE7, follow this sequence for flashing the files: PG7 > PH1 > PI > PK2, PL1 > PL4.

  6. If your phone’s build number is PL1, only flash the PL4 file.

Change the name of the downloaded file to “Update.zip.”

Preparatory Steps

  1. Ensure that the update is specifically designed for the Galaxy S7 Active SM-G891A. Do not attempt to use it on any other device.
  2. Back up all data, including text messages, contacts, call logs, and media files, to prevent data loss during the update process.
  3. Verify that your phone does not display “custom” in the download menu before proceeding with the firmware flashing process on your Samsung Galaxy S7.
