[Q] Phone not unlocking
So I have gone from stock 4.2.2 to stock 4.1.2 flashing with Odin. Got stuck in a boot loop so had to go to android recovery and factory reset. Then I tried using titanium backup to restore my apps but that didn't work fully and it got stuck in a boot loop on the reboot. Factory reset again and seems to be working fine now. Phone is rooted using Kingo Android Root and used Titanium Backup again for just one app and it worked fine.
Installed BusyBox and GalaxSim Unlock to unlock the phone and an error message saying that it's unable to read nv data shows up. Restored an efs backup and that did nothing. Also tried using the 8#197 code to no avail. Got that the menu didn't exist and command is 186 after a few clicks.
Any advice? Flash it again?
