Ok so I have been away for awhile but have been helping
@stang5litre on his rom and together we have come up with a pretty great rom. This has all his Rom Control Mods from his other roms and has a new little feature added. The ability to root and unroot rom as you see fit. The unroot feature is achieved by simply flashing a zip in flashfire and you are automatically unrooted and will pass safetynet check and samsung pay will work and all most all custom features of rom will also work. Now to reroot all you simply must do is flash engboot.img in odin thats it no adb root bat or nothing else and as soon as you unroot again safetynet and samsung pay will work again. Wifi and Volte is also working for Tmobile ATT and Verizon sorry no sprint support for volte or wificalling yet. Also I have figured a way to have system root or the modified systemless root you are all using now. You choose on install what you want. This rom is for S7e and S7 users.
@stang5litre has his own site and the rom is available there. Here is the link
