[Q] Why can't I get radio to work on 4.4? topic

I've been on CM 4.2 for ages, finally decided to make the jump a 4.4 ROM. I decided to try slickricks PA 4.4 Build, which seemed stable enough.

Got it all installed, boots fine, but I have no radio. Zero service. I've tried flashing every radio that RWilco has on his site (Through CWM and Odin), as well as the MK4 modem from here.

I also tried loading a backup of Stock TW (where mobile radio works fine) and doing a PRL / Profile update, but that didn't do anything.

I've just run out of things to try. If anybody has any suggestions, please share. Thanks in advance.
