Okay, so long story short AT&T has cockblocked me from recovering my phone. I know, it has a locked bootloader. I get that. But let me start from the beginning. I was rooted (4.3), and my phone auto updated to KK, and essentially soft-bricked my phone. Well, I had to flash my 4.3 firmware (or so I thought) back onto my phone through Odin. The firmware turned out to be 4.2.2, and all of it failed to flash except the modem. It still started up fine, but I couldn't connect to wifi. It wasn't even an option to turn it on. Turns out I was still on 4.3, with a baseband of MF3, and a build number ending in MK2. I didn't know how to fix this, so I've kinda flashed it with all sorts of things hoping it would help. I've tried all variations of 4.2.2 seeing if I can get things to be all either MF3 or MK2, so far no luck. Well today I tried to flash it with MK2 firmware, and it went like 95% through, and failed. Restarted, and it says "System software not authorized by AT&T has been found on your phone."
This is because of the bootloader, I get it.
The 4.2.2 modem is the only thing to successfully flash. Any clues why? Any clues onto how to recover my phone at all? You guys are true geniuses, please help.
Also, my device status is still on "custom" with the unlocked icon.
Any help would be tremendous, as I feel like a complete and utter moron. I have both Windows 7 & Linux Mint my use, so suggest anything. Please. I'm begging you.
