Use ES File Explorer to delete the Superuser files.
Download ES File Explorer from Google Play if needed
Give root access to ES File Explorer
Click on the slash up top.
Navigate to System folder, then “bin” folder, then find “su” file.
Select SU by holding on to it and delete it.
In the same system folder, navigate to the xbin folder and delete the su file.
In the app folder from System folder delete the Superuser.apk file.
Reboot your device.
Device should be unrooted at that point.
