I apologize if there is a post about this but I did not see one when looking.
So as of the OTA update to 4.4.2, I am no longer able to turn on my wifi at all. When I try to toggle it, I receive a notification from Knox that it has blocked it. I had tried to root my phone prior and Supersu was unable to install because it couldn't get past knox before. (this was prior to the OTA update to 4.4.2). Now that I am updated, my phone barely functions without freezing, and I can't turn on the wifi. I'm not very experienced with rooting Android phones so please forgive me, but how can I restore my phone to an older firmware or how can I root/fix it in its current state. I have tried Saferoot with no luck and Supersu is still unable to disable Knox. Any assistance / advice is greatly appreciated!
