[Q] Install 4.4.2 from another region topic

Purchased a Note 3 Neo in Hong Kong last year.

Model Number: SM-N7505
Android Version: 4.3
Baseband Version: N7505ZHUAND2
Currently running:

KNOX is already flipped, so I don't care.

Browsing http://www.sammobile.com/firmwares/database/SM-N7505/, I see that there are some 4.4.2 for various regions, but I need to have a 4.4.2 base in order to install a custom ROM correct?

I get a "Device has been modified. Software updates are not available" message when clicking "Check for Updates" - so my assumption is I'm going to have to do this manually? But do I just need to wait?

Edit:

Thanks for the help!
