Yea I got it to 11.1.1 after a few crashdump fails having to start over with MSM, but im at 188.8.131.52 now and now it wont even fastboot boot twrp.img oof! PBO3 is not booting either. AAAAAAAHHHHHHHHHHHH!!!!Sorry to have sorta hijacked the thread, I was getting a QualComm Crash Dump, managed to boot the phone y'day evening somehow, but am NOT rooted currently. Will give it a fresh go later today or over the weekend.
PS: Yes I did install the zip from within TWRP (the full 184.108.40.206)
I even tried to flash LOS 18.1 from OOS 10.3 and that fastboot looped the phone, RRreeeeEEEEEEEEEEEE!!!! ;_;
Are these problems only native to OP6T International converts? So much trouble.
