Hey everyone
I did an OTA update and tried to root, only to keep getting "unauthorized access to a secure part of the phone has been blocked" when i tired to install sudosu. I restarted to the phone installed supersu by chainfire, restarted the phone again and launched supersu as soon as it had restarted got a message that knox was detected and that it would try to disable finally success phone rooted, rook check worked and no more annoying security warnings
Hope this helps
