[T-Mobile Samsung Galaxy S6 Edge+] fast69mopar:
Has anyone upgraded their firmware to PK6 and attempted to root? I don't have any issues flashing TWRP with Odin. None whatsoever. When I flash a SuperSU zip or a PHH Superuser zip, I cannot get past the T-Mobile boot animation. It freezes every time. Once this happens I cannot boot to recovery. I can only boot to Download Mode. Hell, I can't even power down my device after I flash a root zip. Just curios if anyone has dealt with this issue. I have attempted to flash SuperSu zips starting with the 2.71 Beta up to the 2.78 SR5 with zero luck. I've also tried with PHH Superuser and I get the same results. Can anyone shed and light on the subject?

After several failed attempts to root my Galaxy S6 Edge+ (SM-G928T) with the latest firmware update to 6.0.1, G928TUVU4DPK6, this is what I had to do to get a working root solution. At no time did I ever have a problem installing TWRP with Odin. Ive been using Odin 3.12.3 but I had the same issues with Odin 3.10.7.

I started with a clean slate and performed a fresh install of the stock firmware which I downloaded from here:

After flashing the stock firmware with Odin 3.12.3 I did the basic setup on my device to make sure I could boot and everything was working. Next, I shut down my device and booted to Download Mode by using the key combination of Volume Down + Home + Power. Once booted into Download Mode I used Odin again to flash TWRP 3.0.2-0, which is available here:

After the flash was complete I booted to recovery using Volume Up + Home + Power. When TWRP starts it will ask you if you want to swipe to allow system modification. If you swipe to allow system modifications you will trigger DM-Verity and you will not be able to boot normally unless you flash a custom kernel that has DM-Verity disabled in the fstab or you can flash the no-verity-opt-encrypt.zip that I dowloaded from here:

https://build.nethunter.com/android-tools/no-verity-opt-encrypt/

The newest version available is 5.0

So, I swiped to allow system modifications. Next, I transferred the no-verity-opt-encrypt.zip from my PC to my device and installed the zip in TWRP. Once this was completed, I transferred my root zip from my PC to my device. I used the PHH Superuser to root my device which is available here:

I installed the root zip in TWRP, wiped cache/dalvik cache and then selected Reboot System. I didnt know if I would be able to boot or not. I could never get past the T-Mobile boot animation each time I attempted to root this damn thing but low and behold everything went as planned and I was fully booted up and running. I went through the setup wizard and everything was working as it should.

I am using PHH Superuser instead of Chainfires SuperSU. Its a personal choice for me as I have been using PHH Superuser since the hand off of SuperSU to a new company, CCMT, LLC.

Once I was finally able to boot normally I downloaded PHH's app in the Play Store from here:

This is just my experience of what I had to do to get root working on my S6 Edge+. All of my root apps are working as designed. I cant remember the last time I didnt have a rooted device and it was starting to bother me. I was having root withdrawals. If anyone decides to upgrade to the latest firmware from T-Mobile and wants a working root solution, here is what worked for me. I have not tried to use Chainfires SuperSU again. If you dont want to use PHH Superuser and wanted to use SuperSU instead, try to insert SuperSU in place of PHH Superuser and see what happens. Do this at your own risk because I have not tested it with this solution that I found. Good luck. Happy Rooting!!
