Install UCU4CRE4 Android 8.0 on AT&T Galaxy S7 G930A Oreo Stock Firmware

This is the perfect guide for the AT&T Galaxy S7 users to update their device to the latest UCU4CRE4 Android 8.0 Oreo Official Firmware. The major system update was rolled for the international model of Galaxy S7 a few months back. But finally, it started rolling for the US variants too. The update is being rolled via OTA (Over-the-air), and the customers started receiving it. However, if you are in a Custom ROM, or your device is rooted, you won’t be eligible to get the OTA package. In that case, you can follow our tutorial below on How to update Galaxy S7 G930A to Android 8.0 Oreo Official Firmware. We have a manual step-by-step guide to install the update via Odin tool, read ahead — and also you can root your device on this firmware.

Galaxy S7 G930A

Samsung Galaxy S7 is aging! So take this opportunity to upgrade your phone with a factory reset in order to remove the unnecessary files and cache junks, and start with a new clean OS.

The update comes in at 2 GB (approx) and comes with April 2018 Security patch. But before starting the tutorial, please make sure to backup your important files.

Backup your Android Device

We don’t want you to lose any data, or anything could go wrong unexpectedly. Before starting the tutorial, we strongly recommend you to make a full backup of your phone.

Samsung users can use Samsung Smart Switch to backup data on the computer. Smart Switch even allows the users to move data from one device to another of different variant (like moving data of Galaxy S7 to Galaxy S8).

Once you are sure that you have completely backed up your data, install UCU4CRE4 Android 8.0 on AT&T Galaxy S7 G930A using Odin. All the download links are given below — read ahead and grab them all to start the tutorial.
