Motorola GP Series CPS Unlock

The GP series of radios are locked to a specific region code by the CPS. Meaning you can’t program US radios with an Australian CPS, for example.

The lock is in the CPS, not the radio, and there’s a registry workaround:

  1. Install Motorola CPS
  2. Reboot machine
  3. Open Regedit
  4. Go to HKEY_LOCAL_MACHINE -> SOFTWARE -> Motorola -> ProRadio -> FSK
  5. Edit the string called “SerializedString
  6. Replace data with
  7. Open CPS software

Now you can program it regardless of region.
