I own Samsung Galaxy S4 (GT-I9505) running Omega v31 so it has only been tested on this rom and model, but it should work on any other tw-based rom. I am not responsible for any damages, bricked phones, etc. You should also make a nandroid backup before applying this mod.
Let me know if it works for you and hit the thanks button if you like my work
