I just installed Cyanogenmod 11 on my Xoom Stingray 4G. The Xoom is running great, but I have no data service. After setting up the new partition , I tried installing OmniRom and Cyanogenmod 10.1 and EOS4. With EOS4 I had 3G service, but no 4G. With everything else, I have had no service at all. What am I missing? I had perfectly functional 4G before the change, but on a barely operational tablet.
