Samsung Edge SM-G925T wrong root

So here’s my situation. I tried to root a Samsung S6 Edge from Tmobile, running 5.1.1. I used the method for 5.0.2. I did not know for the 5.1.1 there is a kernal in order to CF root this phone. Of course is stopped loading and gave me kernel is not seandroid enforcing. Now I have tried to factory rest with TWRP, with Davlik and cache and install firmware again to get the phone back and running. I have tried using Odin, as well as TWRP(using ADB) to install the stock software. It will not flash the firmware using either. I even tried using PIT file to repartition. That does not work either. Just starts up and quickly stops with the load. Any suggestions?
