Here is what happened, i downloaded the OTA from AT&T, unrooted my phone and installed the update. It went all the way through, rebooted and that's where it stops. As soon as the AT&T welcome screen comes up the phone just freezes. When i plug it to my PC the phone is not recognized. Kies says it can't connect to the device. I'm able to get into download mode and odin seems to find the phone. But in download mode there is no option to reboot or anything. It only says "custom" on all options.
Can anybody help?

Factory reset usually solves most boot hangups. It will wipe your internal sd if you have stock recovery though.

i can't find any option to do a factory reset. I flashed Philz touch with odin, it said it passed. Tried a factory reset but it still freezes at the AT&T homescreen.
Any other way to do a factory reset?

Why'd you re-root BEFORE installing the update? Is there a particular reason? From what I've read on here, towelroot will easily root it afterwards.

I took root off the phone since most of the time root stops OTA updates. Then i downloaded and installed the update. I had plans to root it again after the update.

Hello there. I also attempted the 4.4.2 OTA from stock 4.3, and now I'm having this exact same issue. The device had TWRP recovery installed, so I re-installed the stock recovery. It was also rooted and a few system files were edited (lock sounds, hosts file), I reverted all the changes, did a full unroot via SuperSU and proceeded with the OTA. It seemed successful until it tried to boot.. it now freezes on the AT&T logo, as the OP mentioned. I installed TWRP recovery again via Odin so I could back up all the data from the phone and do a factory reset. Unfortunately, this did not fix the freezing. I've attempted reverting back to the latest official Odin .tar (4.1.1), which I've now learned is not possible since the 4.3 update and its locked bootloader. It would seem that the only thing that would do the trick now would be an Odin-flashable 4.4.2 tar. For now, I've installed CyanogenMod as a temporary solution.

I dunno if it has been tested yet but this is a TWRP/CWM flashable zip which also preserves root.

this worked for me
Hi All, Just wanted to share a solution that worked for me. I was in the same boat. OTA update locked phone on ATT screen. Used steps 2 and 6 from link below and now have 4.4.2 running on my phone. Happy flashing.
