Good day, thanks for reading.
Have an s6 which is blacklisted on (tmobile).
It was sold with an IMEI hack to which I have a TWRP modem and efs partition backup.
On the stock 5.1.1 I was always able to use twrp to restore those partitions and the phone would be unlocked and connect to network (metropcs).
One day it did some weird ish, it FRP locked and wouldn't work. Along the way fixing this, I upgraded to Android – Marshmallow.
All said and done my twrp partitions no longer unlock the phone due to the radio partition not restoring properly.
Now I cant go back to 5.1.1 due to SW REV CHECK FAIL DEVICE 4 BINARY 3 error using Odin and Sammobile stock roms.
From what I understand, there are locks preventing a bootloader downgrade.
Is there anything I can do at this point?
I think one way around this problem may be to have a stock TWRP backup for a G925T which I think would overwrite the boot partition and everything else and allow a total downgrade.
Would anyone possibly have something like this?
Ill appreciate any input, thanks!
