System Update After Removing Root

[unroot]

I previously rooted my Note 3 (I do not remember what technique I used). I also disabled OTA updates using NoBloat Free. I have since removed root using SuperSU but I cannot check for updates via Settings -> General -> System Update.

I'm currently running 4.4.2 and I would like to upgrade to the latest OS version. Here are some other specs - Baseband N900PVPUCNAB, Kernel version 3.4.0-533717. Any suggestions?
