Hello, Mike! We will post here the legacy Magerit Updater. It does not use “chgport”, so you need to know your METRO’s COM port number. You can check it in the devices manager. In case you module is not recognized in the device manager (Unknown devices/Others), you can install the drivers in Windows Update – Optional Updates.
Then, the update procedure is quite simple. In the folder there are all the instructions available (only a few simple steps)
Best regards, David.
