Default [Q] OTA Failed?

I have the AT&T Galaxy S4, i337 MF3 build that is rooted on 4.2.2 I am trying to update to the newest OS but I cannot do the OTA update my guess is because of my root, I tried ODIN but it keeps giving me errors...please can someone point me in the right direction of how to remove my root, or preserve it and update to the new operation system..thank you.
