Earlier today i flashed a stock rom, locked my bootloader, and flashed the stock AT&T recovery in an attempt to recieve the 4.2.2 update. As i was checking for the update, a 13.8 mb update was downloaded, however when it tried to install, a red exclamation point came up. So i restarted and tried it again and no luck. So then i decided to run the RUU and start fresh and try again. However this time, the update is not being recieved. Any ideas or hints that you guys have?
