Install Android 6.0.1 Marshmallow Update for T-Mobile Samsung Galaxy S6

The T-Mobile Galaxy S6 users are now able to upgrade their phones to Android 6.0.1 Marshmallow OS.

If you don’t want to wait until the update is released in your region, then you will be able to follow the info listed in this post and learn how to flash the new firmware manually using Odin app. Odin is a small tool designed to help Samsung users upgrade their phones without waiting for the OTA files.

Check the following guidelines before starting the installation:

  • use this post only for the T-Mobile Samsung Galaxy S6 models.
    – check the version of your phone under Settings> About Phone and make sure that the SM – G920T model is listed there.
  • do not update any other devices with the files that you will find in this post.
  • download Samsung USB drivers from here and install them on your PC.
  • Odin requires your PC to run the latest Samsung usb drivers and for the USB Debugging to be enabled under Developer Options menu of your phone.
    – if you can’t find Developer Options, then you should go to Settings> About Phone and tap 7 times on the Build Number text.
    – return to Settings and open the Developer Options to find and enable USB Debugging.
    – this will allow your phone to detect the computer and you to complete the installation easily.
  • if your device is running rooted firmware you need to know that root access won’t survive the update.
    – any custom Recovery that you might have installed on your device is going to be replaced with a stock Recovery.
  • the update can be installed over custom ROMs, too, but you will have to ‘factory reset’ the device after the new firmware is done installing.
    – the ‘factory reset’ steps are listed at the end of this tutorial.
    – factory resetting the device is going to wipe clean the system partition, but it won’t delete any data from the internal storage of your device.
    – the factory reset removes the custom ROM and it will allow your phone to boot in normal mode.
  • if your phone sports 100% stock Android, then you can continue to the next part of this post right away and start the update.
  • read the whole tutorial and do not skip any steps.
  • this is a tutorial that needs to be used by advanced Samsung users only.
  • we cannot be blamed if you brick the phone nor in case you lose any data in the process.
  • check the battery charge of your Galaxy S6 TMO before starting installation, as there needs to be at least 50% power left before the device switches off.

If you don’t want to manually update your Galaxy S6, then you should wait until Samsung pushes the new update manually in your region.

You can look for new firmware updates by going to Settings> About Phone> Software Updates menu. If there is a new Android software ready to download you can confirm the download and installation, then let your phone do the rest.

How to install Android 6.0.1 Marshmallow Update manually for T-Mobile Samsung Galaxy S6:

  1. Download the Android 6.0.1 G920TUVU4EPF1 firmware archive from here.
  2. Extract the contents from the archive and save them on your PC.
    – you will obtain the G920TUVU4EPF1 tar.md5 firmware updating file.
    – do not extract any further than that.
  3. Download Odin 3.10.7 from here.
    – extract Odin contents and save them on your PC.
  4. Power off the phone.
  5. Boot it in Download Mode.
  6. Launch ODIN on your computer.
  7. Connect your phone to PC via usb cable.
    – wait for Odin to add the device.
    – in case no phone is added you will need to try and reinstall the Samsung usb drivers once more.
  8. In ODIN go to Options tab and make sure that the ‘re-partition’ option is disabled.
    – do not edit other default Odin settings.
    – in case ‘re-partition’ was already disabled you can continue to the next part of this post.
  9. Click the AP button in ODIN.
  10. Find and load the G920TUVU4EPF1 tar.md5 firmware updating file. That’s the same file you’ve obtained at step 2.
  11. Hit the START button to confirm installation of Android 6.0.1 update.
  12. When the updating process is done installing you can see the PASS alert shown by ODIN. Your phone will also reboot in normal mode now.
    – note that the first boot process is going to take a while before it loads all the new software files.
  13. Unplug the phone from computer when the “optimizing apps” screen loads on your device.
  14. Use your default login info in order to regain complete control over your device again.

These were all the steps that you had to take in order to finish installing the Android 6.0.1 Marshmallow update for your Galaxy S6 T-Mobile.

If the FAIL alert is displayed by ODIN, then the updating process has to be repeated. In case you decide to retry installation of Android 6.0.1 update, then you should make sure that your phone meets all requirements and that you won’t skip any steps in the process.


If the PASS alert is shown by ODIN, but your phone enters in a boot loop, or it gets stuck at the boot animation screen for more than 20 minutes, then you need to ‘factory reset’ the device.

The Factory Reset process is going to wipe the system partition, but it will allow your phone to boot in normal mode. Factory Resetting the device won’t remove any data from internal storage.

The ‘factory reset’ steps listed below should be applied by those that have installed the Android 6.0.1 update over a custom ROM, too.

Here’s how to factory reset your smartphone:

  • power off the phone.
  • boot it in Recovery Mode.
  • select ‘wipe data/ factory reset’.
  • confirm.
  • reboot device in normal mode.
