After (a failed?) firmware-update and restart one of our MultiPlus-II 48/3000/35-32 GX just shows "Victron Enery" in the display and stopped working. Furthermore there is no LAN connectivity (can't ping, no web, no ssh). Reset (button) and completly power-off does not change anything. Is there any way to flash the firmware again (the device has no sd-card-slot, just one usb-port)? The device is in France and I'm on site for the next days. Any assistance / ideas would be appreciated :) Andreas
