I am in that sad group that cannot unlock the bootloader on 4.1.2, so I was very happy to see the post above.
I tried to take the update to KK but it fails. I used VooDoo Root Keeper to temp unroot before letting the update run, but no luck.
What did I miss? I am still running stock 4.1.2, with nothing special loaded. No system apps were deleted or frozen. I really want to upgrade to KK, root and unlock before they fix it.
Any help?
Thanks in advance,
