Unfortunatly' SuperSU has stopped
Samsung Galaxy S3 - SPH-L70 with 4.4.2
Followed Chainfires root procedure. Got the red android during reboot, etc. Downloaded Root Checker from Play Store and it says - do not have root access. So I downloaded SuperSU, and the screen message 'Unfortunately, Super SU has stopped' appears. So I downloaded the pay version of SuperSU. Still no change. Now, every time I go to use the phone, I get the message that SuperSU has stopped.
I have never rooted before. So I need help and hopefully posted in the correct forum
