Install Android 8.0 Oreo on AT&T Galaxy S7 & S7 Edge (SM-G930A/G935A)

Rakesh | 27 Jun 2018 | ROMs/ Samsung

Oreo on AT&T Galaxy S7 & S7 Edge

It has been more than a year since we shared a tutorial describing the manual installation of Android Nougat firmware on the AT&T variant of the Galaxy S7/S7 Edge. If you own this great phone and have been waiting for the latest Oreo update, you need not wait anymore as AT&T has recently started rolling out the Oreo OTA with Samsung Experience 9.0 for the S7 and S7 Edge. Luckily, we have got hold of the full Oreo firmware with build number G930AUCU4CRE4 for you and today, we’ll show you how to install Android 8.0 Oreo on AT&T Galaxy S7 (SM-G930A) and AT&T Galaxy S7 Edge (SM-G935A) manually using the latest Odin.

In case you own the non-AT&T Snapdragon variant of the Galaxy S7 or S7 Edge and have stranded this page my mistake while looking for the Android Oreo update for your S7, you should check out this guide to flash the Oreo firmware on your phone. The users of Verizon Galaxy S7/S7 Edge should use this tutorial instead.

Android 8.0 Oreo is definitely a major update for the Galaxy S7 and S7 Edge. While the carrier-unbranded models of the phone received the update about a month ago, the AT&T and Verizon variants users reported receiving the OTA just a few days ago. If you haven’t yet got the update notification, you can check for its availability manually by tapping the Software updates option found under Settings > About Device.

Please note that if have rooted your AT&T Galaxy S7 or S7 Edge, disabled any system app or live out of the United States territory, you won’t get the official OTA updates on your devices. However, that doesn’t mean you can’t enjoy the latest Oreo on your S7 or S7 Edge. By following our tutorial, you can install the Android 8.0 Oreo on AT&T Galaxy S7 and S7 Edge with Samsung Experience 9.0. You can also use the Odin method to restore your phone to stock or fix issues like bootloop and sluggish performance.

Install Android 8.0 Oreo on AT&T Galaxy S7 & S7 Edge

Now, here are the Android Oreo firmware installation instructions.

  1. Download Odin3_v3.13.1_3B_PatcheD.zip and unzip it. If you try to install the Oreo firmware with any other version of Odin, you’ll get “emmc_appsboot.mbn.lz4” error.
  2. Make sure you have the Samsung USB Drivers installed on your PC.
  3. Go to Settings> Developer options on your Samsung Galaxy S7 and enable USB debugging.
  4. Precautionary step: Don’t forget to backup your apps and data stored on your phone’s internal storage.
  5. Now turn off your Samsung Galaxy S7 and boot it into the Download or Odin mode. To do so, press and hold the Volume Down + Home + Power keys at the same time for 2-3 seconds. Release the keys as soon as you see a blue screen with exclamation sign and press the Volume Up key to get into the Download Mode.
  6. When your phone gets into the Download mode, open the Odin folder double-click the Odin3_v3.13.1.exe file to launch it.
  7. Connect your phone to your computer using the original Samsung USB cable.
  8. When your phone is detected by Odin, the ID:COM port will be highlighted (see the screenshot below).
  9. Now click the BL button in Odin, navigate to the firmware folder and add the file that starts with BL in its name.
  10. Then click the AP button and add the corresponding file to it. Since the AP file is huge in size, Odin will take some time to add it.
  11. Now click the CP add the CP file to it.
  12. Finally, click the CSC button and add the CSC file to it.
  13. Having added all files, make sure your Odin’s screen looks like as shown below.
  14. Finally, click the Start button to initiate the installation and wait until the installation completes.
  15. When the firmware is installed, you will get PASS! message in Odin and your phone will reboot automatically.
  16. You can now disconnect the USB cable. Since the first boot takes about 5-8 minutes, so you need to be wait patient.

When your device boots up, you’ll be able to use your device. Enjoy the newly installed Android 8.0 Oreo firmware with build version AUCU4CRE4 on your AT&T Galaxy S7 or S7 Edge.

Fixing Post-Update-Issues

In case you notice any abnormal behavior like slower performance, app force-closes, overheating, etc., performing a data factory reset will fix such post-update issues. You can find detailed steps on wiping cache and data partitions and resetting your AT&T Galaxy S7 here. If wiping the cache partition doesn’t help, perform a data factory reset.

    Hello, i recently bought a imported S7 Edge (SM-G935A) unlocked from At&t in Argentina , when i tried to update it says that has the last version but it has android 6.0.1. For that reason i want to update the device with this method but i have two questions: if i update with this method my phone will remain unlocked? Because i need to use it with Argentinian SIM. The second question: can i install Oreo directly as it says this tutorial from 6.0.1 or i have to update one by one the updates in the order they have been released?

      Hi Franco, this Oreo update tutorial is meant for people like you who are using the AT&T S7 or S7 Edge out of the US territory because people don’t get OTA update if the use their phone with some other network or in some other country.

      Installing the firmware from above won’t lock your phone if it’s already network-unlocked. So you can proceed.

      As for the other question, just download the latest Oreo firmware from above and install it using Odin. You can install the full firmware on any version. Flash it and do share with us how it went for you. Cheers!

        Another two questions if i factory reset the phone once i have already install Oreo, will i lose the update? And the second question : in case the first question is no, is possible to come back to 6.0. 1 once i have installed Oreo? I want to know because the warranty says i loose the warranty if i modified the software

      Hi Marco, if your confused by the option buttons for firmware fields, I’ll clarify for you:

      Add BL file to Bootloader
      AP file to PDA
      CP file to Phone
      and CSC file to CSC.

      I am not sure if JOdin will work properly with the Oreo firmware. You can still try or borrow a Windows machine from a friend.
