I won't mention which particular ROM this is, as I am only using it for personal use and have no wish to make the developers of the particular ROM feel as though I am expecting support for this clearly unsupported endeavour. By copying over the appropriate libraries (APNs, RIL drivers, etc) and editing build.prop, I was successfully able to boot the ROM, and all network functions worked with the exception of receiving phone calls (mobile data of all speeds, outgoing calls, send and receive SMS, wifi, Bluetooth, and GPS). Would anyone here have any clue what I could have missed? I realize that this is a fairly open ended question, and am not expecting a lot.
