Recently I wanted to unroot my Galaxy S4 ATT I337 and return back to Stock. It hasn't been my first time doing this, so I knew sort of what I was doing. I used Odin v3.10 and flashed an NB1 tar file and it worked fine, but as it finished flashing it said the device had been removed, showing up as a fail. So I disconnected the cable and tried again, and started getting error messages. I guess it might have had to do something with that, but now it keeps giving me a fail message every time I try to flash with Odin.

My phone now shows this firmware error on default and Odin seems to be failing every time. Is there anyway to fix this, or did I just completely screw this up?
