i have reached a point where i actually dont care about it. this knox is really so annoying i wouldnt care if my s4 is bricked or broken. Especially the kitkat releases by samsung were disappointing.. first one no glonass.. second one with knox2.0 and random reboots..
I would get a different brand where at least customers are not treated like this... htc makes a lot of things better these days and the dont even exclude warranty if i interpret it correctly on htcdev. only if error is obviously caused by cfw
