I have the exact same issue. Any news on this? Broken ethernet-port, unable to flash with USB-only. Have tried all compatible DreamUp-versions without success. Also flashing just SSL and checking for bad sectors.

A5-serial. Prod. date May 2010.

Or can anyone point me to some info on fixing the ethernet-port? I can only find for DM800. The LED's doesn't light up at all.

Thanks
