Install Android 7 Nougat Security Update for T-Mobile Samsung Galaxy S7

Android 7 Nougat March Security Update is now live for the T-Mobile variants of the Samsung Galaxy S7. Check the info in this post in order to learn how to manually flash the new firmware.

This update is being rolled out in stages for all users, but not everyone will get the new files at the same time. If you don’t want to wait until T-Mobile and Samsung will release the new update in your region, then you should be able to complete the installation with the ODIN app.

This guide can be used in case you are now running a custom ROM on your device, as the files found below are packing the complete Android 7.0 firmware update file.

Read the following guidelines before starting the flashing process:

  • use this guide only with the T-Mobile Samsung Galaxy S7 models.
    – the version of your phone has to be the SM – G930T.
    – don’t try to update other different Galaxy S7 phones with the files that you will find in this tutorial.
  • download the Samsung USB drivers from here and install them on your PC.
    – these drivers will allow your computer to detect the phone when these two are connected via usb cable.
  • for the updating process we will use the ODIN tool, and this app requires you to install the above usb drivers and to enable the USB Debugging option from the Developer Options menu.
    – Developer Options might be hidden, go to Settings> About Device and tap seven times on the Build Number section.
    – return to Settings, open Developer Options and enable USB Debugging.
  • the Android 7 update can be flashed over rooted firmware, but you will lose root access after the update is done flashing.
    – the custom Recovery that you might have installed will be replaced with stock Recovery.
  • you can install the Android 7.0 update over custom ROMs, too, but you will have to Factory Reset the device after the new stock firmware is installed.
    – the Factory Reset steps are listed at the end of this post, and you should apply them in cae the phone gets stuck at the boot animation.
    – Factory Reset won’t delete any data from internal storage, as it only deletes the custom ROM and wipes the system partition.
  • if your phone runs 100% stock Android firmware, then you can continue to the next part of this post right now, as no data will be lost in the process.
  • this guide has to be used by advanced users, we cannot be blamed in case you brick your Galaxy S7 phone, nor in case you lose any data files.
  • read the entire tutorial and do not skip any steps.

Now that you know all of the above you can continue to the next part of this post.

How to install Android 7 March 2017 Security Update for T-Mobile Galaxy S7:

  1. Download the Android 7 Nougat update file from here.
  2. When the download is completed you can unzip the archived contents.
    – save the files on your PC and don’t extract the tar.md5 file.
    – the obtained update file will look like this G930TUVS4BQC1 with tar.md5 as a file extension.
  3. Download Odin 3.12.3 zip from here.
    – unzip its contents.
  4. Switch off your phone.
  5. Now boot the Galaxy S7 T-Mobile phone in Download Mode.
  6. Launch the Odin app on your PC.
  7. Use an USB cable to connect the phone to PC. Wait for Odin to detect the device.
    – if the phone is not added you need to reinstall the Samsung usb drivers.
  8. Get to Odin’s main menu and click the AP button.
  9. Find and load the G930TUVS4BQC1 tar.md5 firmware update file in ODIN.
  10. Press START to begin the update process.
  11. When the installation is done you can see the PASS alert in ODIN and you can reboot the phone.
  12. Unplug your Galaxy S7 from PC and use your default login data to unlock its homescreen.

NOTE: if the FAIL message is shown by ODIN, then you will have to reinstall the Samsung usb drivers once more and to repeat the whole tutorial again. If you repeat installation you need to make sure that you won’t skip any steps, and that your phone meets the requirements posted above the tutorial.


If the PASS alert is shown by ODIN, but your phone enters in a boot loop, or it doesn’t go past the Boot animation screen for more than 20 minutes, then you will have to Factory Reset the device.

If you Factory Reset the device you will wipe the system partition only. This Factory Reset helps those that have flashed the official update over a custom ROM.

Here’s how to Factory Reset your Galaxy S7 T-Mobile:

  • power off the phone.
  • boot your phone in Recovery Mode.
  • select ‘wipe data/ factory reset’.
  • confirm process.
  • reboot your device in normal mode when you’re done.
