But CSC Changer requires root, and getting root trips Knox, as far as I'm aware.
I'm also looking for a way to change CSC without tripping Knox, as I want to move from a carrier branded device to unbranded (BTU). I think that I can just flash a BTU ROM, but then it won't get updates as the CSCs won't match.
1. Use secret code from my previous post, you might overlook that part
2. Use Odin to flash your desired CSC
You don't have to root your device to change CSC
