I had my note 2 rooted using Kingo one click method before and recently unrooted prior to the OTA update. I am running stock 4.3 and don't have a custom recovery installed (that I am aware of at least). I've received the system update message twice now and tried to install it both times. It appears to go through but then when it finally boots up nothing has changed and I'm still running 4.3. Any thoughts?
