If you have a problem with your MMDVM Hat seeming to have been locked by the vendor, you can try this to unlock it:
SSH into your Pi-Star, stop the services trying to use the Hat:
Unlock the MMDVM_HS:
Update the Firmware:
The above command will only show you the update options, find your desired modem from the list, and run the above command with the suffix for your modem.
Please note: *I* do *not* have a modem with locked firmware to test this on, you follow these instructions at your own risk.
