Install TWRP & Root T-Mobile Galaxy S6 Edge G925T

With the Galaxy S6 Edge, Samsung managed to pull the curtains off from the most beautiful Galaxy yet. Galaxy S6 Edge’s dual edge display packed up inside a metal build makes it extremely beautiful and gives it a great premium feel. Galaxy S6 Edge occupies some mighty specifications which include a 5.1-inch QHD display with a 5 MP camera on the front. A 16 MP shooter is fixed at the back. Samsung has used its very own Exynos 7420 Octa-Core CPU to power this device up. A RAM of 3 GB is fixed inside. Samsung has made the best use of the Edges on this device. It can be used for notifications or news feeds. 

Galaxy S6 Edge is now available through all the carriers as well. T-Mobile’s Galaxy S6 Edge carries the model number G925T. Users who have got or who are ready to get their T-Mobile Galaxy S6 Edge, they may not be able to stick with all-things-stock on their device and they may want to push some custom stuff into their device. Luckily, T-Mobile doesn’t put any restrictions on the bootloader. Galaxy S6 Edge from T-Mobile has an unlocked bootloader, you can load a custom recovery easily into the device but only if you have one. TWRP recovery came up pretty early for all variants of the Galaxy S6, which also worked for some variants of the Galaxy S6 Edge. But the TWRP recovery which worked for T-Mobile S6 didn’t work for T-Mobile S6 Edge. XDA developer recognized developer bigbiff seems to have this issue resolved and with a few compromises brought up the TWRP recovery for T-Mobile Galaxy S6.

The recovery will allow users to perform all basic functions including flashing zip files, creating and restoring Nandroid backup etc. The only bug at the moment is in the Reboot button, it will reboot you into the recovery regardless of the option which you tap. But it doesn’t seem a great deal here as you can always use power key to reboot your device. Another issue that was faced by some users was the deep sleep issue. Using a custom recovery didn’t let the device go into deep sleep mode and users had to revert back to stock recovery. this issue also seems to be resolved by means of a kernel issue brought up by XDA senior member  eousphoros. So, you’re all good to load a custom recovery on your T-Mobile Galaxy S6 Edge and tweak it to get the maximum out of it.
