Android 5.1.1 Blck Lollipop ROM Details:

Like mentioned earlier, this Android 5.1.1 Lollipop firmware for the T-Mobile Galaxy S6 Edge G925T is based on a leaked dump of this firmware. It has been made compatible enough to run on the T-Mobile variant of the Samsung Galaxy S6 Edge. Here is a note/message from the developer attached in the original thread:

Please make sure you have a recent back up of your phone. Also doubly make sure to backup your /efs folder and your /dev/block/platform/15570000.ufs/by-name/RADIO device. There is a risk of permanently bricking your device if the radio upgrade fails. Remember this is all at your own risk. I promise no function or fitness of use.

A few more optional tips that you should remember:

1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich, Jelly Bean, KitKat and Lollipop.

2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?

4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend NOT to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model. And also make sure you have an unlocked bootloader (except Samsung).
