Digi Connect ME Firmware upgrade failed!

I just upgraded from the original firmware on a Digi Connect ME to the latest firmware.

The upgrade was reported as “successful” and I was notified that the Digi Connect ME would reboot.

It never came back from the reboot.

The program DigiDeviceDiscovery found no devices.

Is there any way to connect the device so that i could make a new upgrade?
The device has no Jtag-Interface!


check your serial port for a menu.
