How to unroot note4 and upgrade firmware?

[AC Question]

Hi all,
My note4 was being rooted using CF-AutoRoot. Now some of my phone apps are conflicting because my phone are being rooted. I want to unroot my phone and at the same time upgrade my firmware from Kitkat 4.4.4 to lollipop 5.1.1. How can I do this?

Just flash 5.1.1 using Odin making sure you use the correct firmware for your device

You won't find a comprehensive answer here. Best you join and read the XDA forums for the Note 4... forums are separated by carriers.
