Hi, I tried updating to 4.1.2 on AT&T w/ a Galaxy S3 but I received an error in Clockwork Recovery when the phone rebooted. Is the correct way for me to upgrade to 4.1.2 to download the ROM and then flash via Clockwork? If so, can I download the actual stock ROM? If not I am guessing my only option to change to the stock 4.1.2 (which was recently released) will be to replace Clockwork with the stock recovery?? Thanks for any help!
