I'm having trouble with my super su.
I can't seem to get it to install. I click the app and click install it does it thing. Then ask me to use super su to turn off annoying knox notification three option never, cancel, ok. I of course click ok. Then it says insulation failed please reboot or close. Does anyone know how to get this to work. I tried factory reset I tried many times to re root it nothing seems to work.
Leave your phone model and android version please~
It seems that you need to reinstall the SuperSU, with twrp and supersu.zip, through recovery mode.
