The only way to update the firmware without tripping Knox is to flash a custom ROM if you are already rooted. Even then, there might be certain steps for you to follow to ensure that Knox isn't tripped.

Otherwise, all other methods will trip it. Regarding your issue, you may need to clear cache through recovery or perform a factory reset (worst case scenario) if the problem doesn't go away.

The device is not rooted. How can i chek if Knox has tripped or not!! Just for the info, i kept it to get updated for a whole night but the download dint start. it said " Knox updating, dont switch off the device."
How to clear cache?
