Is it SM-960U OR SM-N960U1 ?First of all, THANK YOU THANK YOU for getting back to me. I can't tell you the model number because I can't get into the OS. I've been trying to find it online.
I've used Odin 3.13.1 3B Patched, 3.13.1, and 3.14.1. All of them fail.
go to sammobile and get the latest firmware , probably you loading a firmware that's older then what you have on it now .
Download mode can give what build number on it .
Your welcome!
