Default [Q] Note 3 neo n7505 knox

Hello,

I have a question.

I have my note 3 for a couple of days. It is my first android device. (always used apple)

I Read something about a knox code. That will trip when I root my device.

Is that true, or is there a workaround?

Also, I read somewhere that KitKat was released for the note 3 neo (sm-n7505)
But no ota..

If I install the official rom of KitKat, will that also trip my knox?

I hope someone can help me with this
