[Q] Baseband and Modem Mismatch, How to fix? topic

Trying to fix my phone so I can update from 4.2.2.
I tried rooting a while ago and somehow ended up with a I9505GUEUBMH5 baseband and a I9505GUEUAMFD Modem(Build Number).

What is the easiest way to fix this? Should I flash the modem bak to MH5 somehow? or is it safe to flash the baseband to MFD somehow?
And if so which is the best and safest way to do it?

Thanks in advance!
