Default [Q] rooted 4.1.2, want to unroot and go to stock 4.3.....

Hello All,

I just bought a galalxy note 2, which has Macksrom allstar 5.0, which seems to be based off 4.1.2. I really want to safely unroot and upgrade to stock 4.3. I have a system update available. Is it ok to just use that to update? I know on some phones, you cant and must use odin and stock firmware. What is the right way to do this?

Thx!
Thank you kindly,
Rosy
