Question [Q] Cannot create new APN (4.4.2 ProBAM)

Hello everyone,

I just flashed a new ROM 4.4.2 ProBAM on my Galaxy Note 2 (GT-N7100) and everything seems to work fine except: I cannot make any calls or access mobile network.

I figured I needed to manually configure my APN but the APN won't save, it stays blank!

I tried the search function for similar case but couldn't find anything. Anyone know why I can't save an APN on 4.4.2?

Thank You,
