What update are you speaking of? I tried to flash stock 4.1.1 but got FAIL message.
Do not flash anything from sammobile because you're on AT&T and they don't have the 4.3 files there. You already updated to 4.3 if you do happen to successfully flash something older through Odin you will have a paperweight for a phone.
Try to do a factory reset. And 4.3 takes a really long time to boot after a factory reset or fresh flash. You will think it is stuck just plug it in to the charger and come back in 10 minutes so you can not be impatient. Let it do its thing. When I Say a long time the last time (yesterday) I flashed a Rom (stock by loserskater) it took 4 minutes and 22 seconds to boot(I timed it had nothing better to do after hard bricking the phone for the third time in a week)

I tried to flash a new mod'd touchwiz launcher and tried to restore from a nandroid backup of dandroid.
After restoring stuck on boot logo.
Tried to wipe and restore again to no avail.
I put the rom back on the sd card and re-flashed and is up and working fine.
You might wanna try this (with your chosen rom).
