I wasn't paying attention to the model numbers I was looking at and tried to install an N7100 ROM on my SGH-T889. I installed it, fudged my IMEI and tried to rollback to the previous ROM I had in place but it didn't resolve my IMEI unknown issue. I tried to restore my backups, nothing. I have tried multiple stock firmware versions for my phone I have found on here but ODIN fails on every single one, most of them sitting at boot.img, MD5 hash invalid or getting stuck on system. I am unable to get into recovery, only the download screen. I think because the ROM I tried was 4.3 it messed up my bootloader and wont let me go back to 4.1.2 but I cant put anything on it at this point. Ive tried multiple versions of ODIN, different USB ports, cables, rebooted my PC and Im out of ideas at this point. I apologize in advance because I'm sure the answer is out there I just cant find it and I've been looking for a few days.
