Problem: If the Mondopad has received a firmware update it may need the serial number re-written to the panel. We have created the SN Write tool to achieve this. However if the computer you are using to do this has had the most recent Windows updates, it will fail.
Solution: The Mondopad PC has a BU restore image stored on the restore partition. Follow the instructions for doing a system recovery and don't run windows updates.
Then run the SN Write Tool on this clean image and it will work properly.
