Flash Android 5.1.1 G920TUVU3DOJ7 Lollipop for T-Mobile Galaxy S6

T-Mobile has issued a new official Android 5.1.1 build for all the Samsung Galaxy S6 users. You can check the instructions listed in this post in order to learn how to manually install the latest Lollipop firmware for your phone.

This tutorial is great for users that aren’t too eager to wait until T-Mobile decides to release the new update firmware in their region, as that might take a while before it happens.

The new update comes with security tweaks and improvements that should make your device more stable and faster than before. Also, note that this update will most probably be one of the final Lollipop builds released, as Samsung and T-Mobile have should start working on Android 6.0 Marshmallow builds soon enough.

Before starting the installation process you should check the following guidelines below:

  • use this post only with the T-Mobile Samsung Galaxy S6 phone.
    – your device’s model number has to be SM – G920T.
    – verify the device version under Settings> About Phone menu.
  • do not attempt to use this tutorial with any other different Samsung devices.
  • download the Samsung USB Drivers here and install them on your computer.
    – the usb drivers will allow you to flash new Android 5.1.1 firmware files on your phone using Odin app.
  • for Odin to work on your computer you will also need to disable Samsung KIES and any antivirus application.
    – these apps are going to block Odin from running on your computer.
  • enable USB Debugging from Developer Options menu on your PC.
    – the Developer Options might be blocked from running, which is why you will have to enable it first.
    – go to Settings> About Phone and tap 7 times on the Build Number section.
    – now, return to Settings and scroll down to find Developer Options menu.
    – find USB Debugging and enable it, too.
  • note that in case your phone is rooted, then root access will not survive the update process.
    – also, any custom Recovery image is going to be replaced with a stock recovery image.
  • you can install the update over a custom ROM, too.
    – for your phone to be able to boot in normal mode after the installation is done, you have to factory reset the device.
    – the ‘factory reset’ removes the old custom ROM and it allows the new official firmware to boot in normal mode.
    – without factory resetting the device your Galaxy S6 device will not be able to boot in normal mode, as the previous Custom ROM system files are present on your device.
    – the ‘factory reset’ steps are listed at the end of this tutorial.
  • if your phone runs an official Android 5.1.1 firmware, then the factory reset steps aren’t necessary.
  • read the whole post and do not skip any steps.
  • note that this is a tutorial that you should use only if you are an advanced user, we cannot be blamed in case you brick the phone nor in case you lose any important data files.
  • check the battery charge level of your device, it should be over 50%, as it will prevent it from powering off during the installation process.

Now that you know all that you can get to the interesting part of this post.
