[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!

md5 sum mismatch error when restoring in CWM - Perm fix? topic

I'm using Nandroid and ROM Manager to perform backups, but when I boot into CWM, and choose any backup created by these apps, I get the "MD5 Mismatch error". I've seen plenty of threads how to fix one back-up file, but why does this keep happening? Is there a permanent fix?

Thanks
