Last usable (as of earlier this morning) ROM: LS 2.7 (4.2.2)
So I *WAS* unlocked and rooted.... now... I don't know what the heck is wrong.
Saturday I downloaded "EZ Unlock 1.2" and installed it; Unlock Status was "UNKNOWN" and even after clicking the UNLOCK button it still showed "UNKNOWN"
So, this morning, I made sure I had the new ROM (LS KitKat 3.0 Nightly Beta 2) on my external SD card, booted in to TWRP, and updated to the latest TWRP (22.214.171.124). I then cleaned out some old ROM backups and made a new one (using compression) which was successful. Rebooted to system, all looked & worked normally, so I rebooted to TWRP Recovery, did a Factory Reset + system (so cache, dalvik, data, & system) and that went fine. Tried to install the new ROM... FAILED. So I rebooted to Recovery and tried to restore the backup I had just made, and it seemed to succeed, but when the phone rebooted, it only got to where it reads "Samsung Galaxy S III" and got no further. I let it sit like that for 10 minutes, then pulled the battery. I booted back in to Recovery and tried restoring a backup made 2 days ago (that I have previously restored from successfully) and that gave a "successful" result, but same thing after rebooting: stuck at where it reads "Samsung Galaxy S III" and would go no further.
I am in DOWNLOAD mode currently and want to get back to the point of being able to restore my backup from 2 days ago. I'll lose text messages basically, and that's fine. I have downloaded ODIN 3.07 but it's been about a year since I last tinkered with it.
Can someone help please? I either get this phone working in the next few hours, or I have to go buy something else off craigslist... or full retail... and I'd really just prefer to get this phone working again.
If I need to "start from ground zero" and redo the boot unlock and root it, so be it. Basically, how do I unbrick my S3?
