I have been trying to find a solution to my xooms horrible radio problems for a month or better now. It seems i am not the only one with fallback issues, but no solutions as of yet. I Big parted and have installed CM, Omni, and EOS ROMS. All with the exact same problem. I can get 4g service just fine- when signal is available. I have yet to see 3g or 1x service. Something with the radio package burned into these ROMS is not allowing the radio to use legacy networks. Maybe would not be such an issue but, here in the middle of BFE, there is only occasional 4g service and usually 3g, always 1x. I have even tried swapping SIM cards and spent a couple hours on the phone with verizon tech support- they are confident it is something with my device. Is there any way to get this resolved? Or are we all SOL. Can anyone get 3g service after changing the preferred network type in settings?
