With this tutorial, you will able to update your Galaxy S7 Edge G935A (AT&T) to UCU4CRE4 Android 8.0 Oreo Official Firmware. A bit late, but the OEM is finally updating its US variant of Galaxy S7 to Android 8.0 Oreo. The new build brings a lot of improvement, features, and UI changes, which AT&T users can take benefits of it. You can immediately get this update on your device manually using our tutorial below. You don’t need to wait for OTA (Over-the-air) to arrive on your phone. And well, our tutorial will work for both modified and untouched device. That means, our tutorial will work even if you had a custom ROM installed or a rooted device.

Update Galaxy S7 Edge Oreo

We have explained the tutorial with some easy step-by-step procedure with Odin tool. All the download links are right ahead — and you can also root Galaxy S7 on UCU4CRE4 firmware.

Since this is a major system update, we recommend you to perform a clean flash. Yes, you can update the phone without losing data, but we strongly don’t recommend that because your device may die with bugs. So clean flash with a factory reset is a must to start your device with a fresh off.

Cleaning the firmware means removing the unwanted residues and bad configurations which are harming your user experience. Luckily, we have tools like Samsung Smart Switch, which can create a backup of your device. Alternately, you also have an option to pick up some cool backup apps from Play Store. Once you are confident enough that you are safe with your backup, you can proceed to the installation tutorial below.

Since this is an Official Firmware by Samsung, your device warranty won’t get void on installing UCU4CRE4 Android 8.0 Oreo.

  1. I have downloaded the zip file from Androidfilehost.com, and inside it, the AP file has extension .meta.tar. So the md5 is missing. Have you checked this? Does it work anyway with no checksum?
