The real trouble came when I tried restoring Motorola's stock firmware. Considering there aren't really any releases of the Google version of the Moto G firmware, I thought that was my best bet. I followed the instructions found here, rebooted, and found I was unable to use any of the cellular features, along with a helpful "No Service" icon in my status area. I have since reinstalled Cyanogenmod, and still have all the same issues.
Here is the About and About > Status pages for your reference:
I have read that similar issues can be caused by having a corrupted IMEI. However, I've pulled the pds partition off the device, mounted it, and found the following files:
batt_health bt camera factory lost+found pds_formatted_v10 public security whisper wifi wmdrm
Is it possible the firmware for the modem is not functioning properly? As a rather low priority, any tips on debugging GPS would be helpful too.
