ATT Galaxy S4: Tried to revert to stock firmware.

[Dustin Chalchinsky]

I have an att galaxy s4 SGH-I337 that is carrier unlocked. Version 4.3 or 4.4, not sure.

My phone is now stuck and wont proceed past the ATT symbol on startup.

I downloaded the firmware from Sammobile and followed the sammobile tutorial on using Odin to install.

PDA: I337UCUAMDL
CSC: I337ATTAMDL
MODEM: I337UCUAMD

Trying to install firmware yields this on the phone

ODIN MODE
PRODUCT NAME: SGH-I337

What can I do?

Am I screwed?

You were probably on a newer version than that. Try using Odin to go to NB1. If you need directions, you can find them at XDA.
