I updated my phone to kitkat using the OTA update while rooted, which was definitely a stupid thing to do, but now my phone seems to be stuck on the ATT splash screen after booting. It's been this way for 15+ minutes. Any way to reset it/unbrick it?

I am able to get into recovery mode and download mode.

Try a factory reset in recovery?

I tried this and nothing changed. Would a flash back to 4.3 stock fix the problem?

I would read about doing that before doing so. From what I've been reading if you're on a certain bootloader, you can't go backwards. I'm by no means an expert, so just read a lot so you're comfortable with doing that. Good luck .

Dont flash old firmware, but older roms are ok to try. I'd start by trying to flash enewmans stock kk rom.

I managed to get the phone back to 4.3 Stock however now I don't have mobile data. I'm thinking this is a modem issue? Anyone have a fix?

I installed a 4.3 modem and it did not fix the issue. In phone status IMEI is Unknown.

You need to install the 4.4 modem on a 4.3 rom

Thanks! I coincidentally figured this out right before checking this post. For anyone having the same issue, check this thread here. It seemed to fix my issues with mobile data, wifi, and pretty much everything else.

Hey im also stuck on the at&t logo. I was rooted but used triangle away to remove the counter and unrooted via super su/user <--- I don't really know the name of it. So i did the ota update and the phone restarted, it installed the update and restarted again and now will not get passed the att logo, even let it stay on over night. How did you get back to 4.3?? I'm a serious n00b so I need detailed instructions, anyone please?!?

Everything in download mode needs to say "official" in order to get the OTA. See if this helps:

If the ota appeared to flash, and its hanging during boot, factory reset should solve it.

Be aware that doing so with stock recovery installed will wipe the internal sd card.
