So long story short I attempted to update my GS3 to the official ota 4.4.2 and it installed 100% but now will not boot past the AT&T logo. It revolves about three times then freezes. I am still able to get into recovery/download mode and I was wondering how I can either get it to fully boot or install some other rom? Pretty noobish at this have only rooted twice and installed CM via the installer. Any help would be appreciated!
