Looking for the most up-to-date AT&T stock Rom. If anybody could direct me to it that would be great. I thought I had it, but it must not be because the one I have seems to have a couple glitches.
The latest stock update for AT&T GS3 i747 is Android 4.3 which you can get it ota. In order to get that, I believe you have to have unrooted stock Android 4.1.2 in your phone. Once you updated you cannot (or with great difficulties) downgrade or go to other roms. Not sure this is what you want since you are in the rooting thread.
You might want to try this: [ROM][12.9.13][TW] .::StockMOD ROM::. | KNOXless | AT&T 4.3 UCUEMJB - xda-developers seemed like a lot of successes in doing that. I have not tried it and like to hear whoever tried that.
