If the Firmware Upgrade fails for any reason, the Comfort Firmware will be corrupted. It will not start and keypads and door stations will beep
Do not panic

You can use this method again to upgrade the firmware and get the system operational

Follow the same instructions.

In Comfigurator, DO NOT LOG IN or do Transfer Information or any other function because there will be NO RESPONSE due to firmware being Corrupted

Go directly to Transfer > Firmware Upgrade and select "By Programming cable Connected to UCM"
