i just root my redmi 4x nougat on twrp recovery. it doesn't made any problem at all.but one thing that make me little bit dissapointed is,i cant edit /system "device or resource busy" (since it system-less root mode)... so to change the mode, i put some string "SYSTEMLESS=false" on a file .supersu at /data. after i try to reinstal again on twrp. i got stuck on loading screen. can sombody help.is this what happened on nougat by reducing access to system?
