WARNING: Flashing any custom firmware to your device will trip the KNOX Warranty Bit. At this time, this is irreversible, and might cause you problems when returning faulty devices to T-Mobile or Samsung. YMMV.
How-To-Install :
- Recognize that this will trip KNOX.
- Be sure you're actually already running the 5.1.1 (OF8) firmware. If you're on 5.0.2 (OCG, for example), this thread is not for you.
- Turn on "OEM unlocking" in Settings -> Developer options. This is the dreaded "FRP LOCK" that prohibits custom firmware from being flashed to the G925T/G920T (and maybe others) - it's something new in 5.1.1.
- Download and Odin-flash my v13 of TWRP 2.8.7.x.
- Download and Odin-flash (or TWRP-flash) my v1 build of the OF8 kernel. G920T users should use the appropriate G920T kernel for their device.
- (Optional): Download and TWRP-flash Chainfire's SuperSU v2.49
- The latest test release is:
BETA-SuperSU-v2.49.zip (.zip format). - (Advice): Use Titanium Backup or some other app to freeze/disable/uninstall "SecurityLogAgent" (remove nagging about security) and "com.tmobile.pr.adapt" (remove nagging about root, helps with sleep, and may be used by T-Mobile to determine your rooted status).
