[Samsung Galaxy Note 8 ROMs, Kernels, Recoveries, &] Kalm_Traveler:
My T-Mobile CSC patch in my signature, been working on it for 3 months to get it so it will work on N950F and N950N firmware, finally got it working on the N variant. I have confirmation that it works on stock N950F, N950N and 3 other F-variant-based custom ROMS, but two people reported that flashing it on LightROM causes many FC upon bootup and I am not sure why, just taking a quick look at your files.

This is the folder structure of what my patch replaces/adds in /system:
