unroot galaxy s4 Odin fail

I am trying to return my Galaxy s4 SGH-1337 to the original - to unroot it. I rooted it but then the wifi didn't work. I tried to fix the wifi issue but after many hours of trying, I decided to just reinstall the original firmware. I downloaded the I337UCUAMDL_I337ATTAMDL_ATT.zip, expanded it and ran it with Odin and it failed. Following is the message stream from Odin.

If anyone can help me with this I would really appreciate it. BTW - I can't download anything directly to the phone because wifi is not working.

Odin message stream:
