hello guys i want to find a solution for my rooted device

[Android Central Question]

first of all i have j7 2016 smj710fn and i have rooted it with supersu manually from twrp by flashing the file(android 7.0 nougat).Now i want to unroot it and then root it
again but with magisk.But when i try to full unroot from super su it says unnroot failed.I have tried it a lot of times and i have tried to flash unsu.zip file but it just deleted supersu and i continued to have root access what to do? pls help me if you know....

Supersu is just an app that controls which app can get root, it's not itself root. The file that is root is a file in /system/bin or /system/xbin named su. Delete that file with a file manager. (As I recall, My Files can't get to /, so you'll have to use something like Total Commander,) The other alternative is to back everything up, flash the stock ROM, then restore everything. (Since you have TWRP installed, that should be easy - just back up data, then restore data.)
