I tried all the sites listed and couldn't get to them from here hence the reason for my post
One site only listed the I747M, and I
do not have the M, I believe that was the sammobile site. I ended up using Samsung Kies to do the factory reset. Best battery life I've had in forever since I've been running stock 4.1.1 8 hours 36 min and still at 25%. AT&T keeps prompting me for an update but I have no WIFI to do the update. I hate the damn touchwiz GUI but I'm going to live with it for at least a few days until I root again.
