Install 5.1.1 Lollipop Firmware on T-Mobile Galaxy S6 Edge (SM-G925T)

0

T-Mobile was the one of the very first US carriers to release the 5.1.1 update for the Samsung Galaxy S6 and S6 Edge to its users giving them the upper hand over the users of other carriers.

The update was pushed out in stages and will come as a notification on your T-Mobile Samsung Galaxy S6 Edge. The Galaxy S6 Edge with its curved screen edges adds a lot more functionality over the original S6 such as these handy features:

  • Night Clock to display the time when phone is kept facing up.
  • Information strips to display various information such as Yahoo weather, news, RSS feeds, Sports and Missed Notifications.
  • When the phone is kept screen facing downwards the edge notifies you of incoming notifications by lighting up to different colors depending on the type of notification called as Edge Lightning.

The 5.1.1 update is surely going to enhance this experience. The official T-Mobile changelog is as follows:

  • Black boxes in email is resolved
  • Camera LED flashlight is resolved
  • Check for Amazon error is resolved
  • Failed to reboot – error message is resolved
  • Fingerprint scanner improvements
  • Various bug fixes and device improvements

Along with these you also get the ability to remove some of the toggles from the Notifications drop-down panel such as Quick Connect and S-Finder which weren’t that frequently used. This update also brings RAW support, lower ISO values and manual control of the shutter speed to the camera sensor, but it requires a third party camera application that has full support for Lollipop’s Camera2 API, since the default camera app doesn’t support these features yet.

There is also a huge improvement in the TouchWiz interface and a lot more emphasis has been given on Material Design in the elements, and most importantly Samsung has fixed the memory RAM management leak which was earlier reported, so you should see some increase in benchmark scores as well, just as it was in the case of the S6.

However if you are one of those who don’t want to wait for the OTA (Over-the-Air) Update and want get their hands on the new update on their T-Mobile Samsung Galaxy S6 Edge (SM- G925T) instantly then follow these steps given below.

Prepare your Device

Firstly you’ll need to prepare a few things in advance before we can start.

  1. Confirm you are using the T-Mobile Samsung Galaxy S6 EDGE (SM – G925T), any other variant will not work and you may end up BRICKING YOUR PHONE!
  2. Enable USB-Debugging from Developer Options in the Settings menu.
    • If you cannot find Developer Options, then you’ll have to first enable it by going to Settings -> About Phone -> Build Number and tap it 7 times until you see a small notification that you have enabled it.
    • Then return to the Settings menu, you should find Developer Options there. Open it and enable USB Debugging.
  3. Ensure that you have at least 80-85% of battery.
  4. Ensure you have all the necessary USB Drivers installed on your PC (Download from here).
  5. Download the Odin flashing tool and extract the downloaded zip to your PC, so now you have Odin3.10.6 folder: Odin3 v3.10.6.zip
  6. Ensure you have a backup of all your personal data.
    • For Contacts, Calendar and People details use Google Accounts Sync to backup
    • For Apps and App Data check out our detailed post.

Note: If you are running in root or on a custom ROM, beware this procedure will remove root and re-lock the bootloader, so you will have to perform unlocking and rooting again separately. For those on custom ROMs there is an additional ‘factory reset’ step that has to be followed after flashing (given below).

Disclaimer: The following procedure is highly risky and there are chances that you may brick your phone of not performed correctly, DroidViews cannot be held responsible if that happens. So you should tread cautiously and at your own risk.

  1. Boot into the download mode. To do this:

    • Press Volume Up to acknowledge the warning and boot into download mode.
  2. Connect your device to the PC via the USB cable:
    • If your phone wasn’t detected then it means you haven’t properly installed the drivers, reinstall them and try again.
    • If the device was connected successfully, one of the ID:COM boxes in Odin will turn yellow, wait for this to happen.
  3. In Odin’s main menu click on the ‘AP’ button.
  4. Search for the path where you had extracted the downloaded firmware files and select the ‘G925TUVU2COF6 tar.md5’ file. Make sure the Re-Partition option isn’t enabled in Odin.

After installation completes successfully you will see your device booting up normally, unplug the phone after the Galaxy S6 logo appears.

  • If Odin showed you a ‘fail’ alert it’s possible either you might have missed a step or this method might not work on your device and you will have to wait for the OTA notification from T-Mobile itself.
  • If Odin gets stuck or freezes during installation, then you have to perform the whole procedure again and double check if all requirements were met.

NOTE: If you were coming from a custom ROM then you need to perform ‘Factory Reset’ after flashing the 5.1.1 update. Use this guide to help you out.
