Here's a functional TWRP with a revamped UI ported from the TAB S2. I am not responsible for ANYTHING to do with this image. Use at your own risk! I can provide only limited help because I myself learned this in one week.
SEANDROID IS NOT ENFORCING? - No Problem - it doesn't mean anything! If you do know how to repack twrp in order to remove that message please show.
Yup I don't mind! You wouldn't by any chance know how disable the text seandroid not enforcing? It annoys me! But without doing it when compiling directly from the tarp tree because it doesn't exist; I only followed a simple twrp porting guide!
