Update US Cellular Samsung Galaxy S7 G930R4 to Android 7 Nougat

US Cellular has started to roll out the new Android 7 Nougat official update over-the-air for all their Galaxy S7 G930R4 devices.

Check this tutorial in order to learn how to manually complete the new update for your device. These updates are being released in stages, and it means that it will take a while before it reaches all users.

The Android 7 firmware file found in this post can be installed over custom ROMs, but for that you need to be an advanced user. Odin is more than capable of both upgrading and restoring Samsung phones to stock Android. More about this can be found below.

Before starting the update process you need to check the following guidelines:

  • use this tutorial only with the Samsung Galaxy S7 US Cellular versions.
    – the model number of your phone should be the SM – G930R4.
    – don’t update other phones with the files that you will find in this post.
  • download the Samsung usb drivers from here and install them on your PC.
    – the usb drivers will allow your computer to detect the phone when they are connected via usb cable.
  • for the update process you need to use ODIN app, and for it to work and connect your computer and phone, you need to install the above usb drivers and to make sure that the USB Debugging is enable on your phone’s Developer Options menu.
    – if the Developer Options doesn’t appear under Settings, then you have to enable that first: go to Settings> About Device> Software Info and tap seven times on the Build Number section.
    – the Developer Options will now be listed under Settings, and you can open it.
    – find USB Debugging and enable it.
  • you can flash the new update over any rooted, but stock firmware, but you should know that root access won’t survive the update process.
    – any custom Recovery you might have flashed you will see it replaced with stock Recovery.
  • you can install Android 7 Nougat with ODIN over a custom ROM, too.
    – if you do that you will need to Factory Reset the phone after the new firmware is done flashing.
    – the Factory Reset process wipes clean system partition, it removes the old custom ROM and it forces the device to boot in normal Android 7 mode.
    – the factory reset will not delete any data from internal storage.
    – note that the Factory Reset steps are listed at the end of this tutorial.
  • if your Galaxy S7 phone runs 100% stock Android firmware, then you can continue straight to the next part of this post, and learn how to update the phone without worrying about losing any data files.
  • check battery charge level of your device, make sure that there is at least 50% charge left before the phone powers off completely.
  • read the entire guide and do not skip any steps.
  • this guide is for advanced users, we cannot be blamed in case you brick the phone nor in case you lose any data files in the process.

These were the instructions you had to go over before starting the update process.

If you don’t want to manually install the new update, then you can wait until Samsung and US Cellular push the new firmware update in your region. You can manually look for new firmware files by going to Settings> Software Update> Download Updates manually, and if there is a new update ready you can confirm the download and your smartphone will take care of the rest of the process by itself.

How to flash Android 7.0 Nougat Update for Samsung Galaxy S7 G930R4:

  1. Download the Android 7 Nougat archive file from here.
  2. When the download is completed you have to unzip the contents.
    You will obtain the Android 7 G930R4TYU4BQC5 tar.md5 firmware update file.
    – do not extract the tar.md5 firmware file, as that’s the file you need to load.
  3. Download Odin 3.12.3 zip from here.
    – after the download is complete you need to extract the files.
  4. Power off the phone.
  5. Boot the device in Download Mode.
  6. Launch ODIN exe on your PC.
  7. Connect the phone to computer via usb cable.
    – after the phone is added you have to continue to the next step.
    – if the phone is not added you need to reinstall the Samsung usb drivers.
  8. Go to Odin main menu and click on the AP button.
    Find and load the G930R4TYU4BQC5 tar.md5 file in ODIN.
  9. When ready for the update press START.
    – don’t press any buttons until the new firmware is done flashing.
    When the PASS alert is shown you can see the phone rebooting.
  10. Unplug the phone from PC and then wait for the Android 7 boot to be completed. Use your default login data in order to regain control over your device.

These were the instructions you had to go over before starting the update process for your smartphone.

In case you are shown the FAIL alert by Odin, or any other error impedes you from flashing the new firmware update successfully, then you have to repeat installation. If you repeat installation you need to make sure that you won’t skip any steps, and that your US Cellular Galaxy S7 phone meets all requirements.

NOTE:

If the PASS message is shown by the ODIN app, but the phone enters in a boot or it gets stuck at the boot animation screen, then you will have to Factory Reset the phone.

The Factory Reset process wipes clean the system partition, and it is a great tool for those that have installed the update over a custom ROM, as their phones won’t boot otherwise.

Here’s how to Factory Reset your device:

  • power off the phone.
  • boot it in Recovery Mode.
  • select ‘wipe data/ factory reset’ and confirm process.
  • reboot your phone in normal mode after the factory reset is done.

I hope that you have managed to complete the update successfully, and that you are already testing all the new features added with this new Nougat firmware build.
