    I have a SPH-L720 Samsung Galaxy S4 that's rooted with Superuser SU running on KitKat 4.42 and things were going fine but then for some reason Superuser SU quit working so root doesn't work and WIFI won't work anymore by not turning on right.When I try turning on the WIFI or head to the Superuser SU app it freezes my phone so I have to push the home key to unfreeze it. Since I have these issues I wonder if there is a way initialize my phone please? I try using Samsung KIES 3 but I got a message saying it doesn't support SPH-L720. I need help badly please, thanks.

    There is a full unroot option in SuperSU. You can try that and then a reset.

    Typically, superuser files are flashed to the device, you may have to reflash a stock ROM with Odin.
