[Q] How to upgrade to 4.4.2 on N9005 without tripping Knox and keep root? topic

I am currently on Android 4.3 and everything is stock. I am rooted and also have knox 0x0.

I would like to keep it that way and want to upgrade to KitKat...

What is the best way to do it? I want to have root again, once i am upgraded....

Any advice? I saw many threads on upgrading but all involve flashing through custom recovery and such things, which will trip knox...
