another way to flash the Dreambox via browser:
Open dcc |(dreambox control centre) when dreambox is connected note the IP address from the box. Then open telnet in dcc and type:
mount /boot -o remount,rw
rm /boot/*
reboot
in browser then enter the IP address from box and choose 'upgrade firmware' and follow the instructions. When upload reach 100% restart box - done
I just did this on DM600
