Problem with Note 3 root

Hey guys, I've got a problem. The problem is.. that I can't get root acces on my note 3. I tried some ways, and nothing.
I've got 5.0 Lollipop, modem version: N9005XXUGBOD1, and system N9005XXUGBOD6. Everytime I try to root it, it fails.
If it's possible I would really apriciate help of someone. :(
@edit: I need the root acces for custom room, cuz I'm afriad that Android 5.1 or 5.1.1 won't come for Note 3.
