[Q] Help flashing stock ATT image. topic

Hello,

Quick backstory. Prior to the last OTA from ATT I could actually get, I had used towerlroot and everything worked fine. I then updated and lost root(naturally). Now I could not get my S5 to OTA to the most recent update (currently running G900AUCU2ANG3) and tried to use ODIN to flash the original Stock firmware. This process failed. Any suggestions on how I can start over?
Edit to add:It is soft bricked now. Can only load into the "Kies" recovery screen
Here is ODIN output: <ID:0/004> SetupConnection..
