Another one here. I think it's because the version of TWRP. If mariogrip could update it to a latest one, it would work, since twrp (2.8.6.0 i can't remeber the exact version) does not work well on some OPOs, as in our case. So please @mariogrip update twrp to 2.8.7.0 at least, in doesn't need to be 3.0
