Respected Sir,

1.) If front panel of LCD displays
"Rescue mode http://dm920.local.lan/"
Then I can copy http://dm920.local.lan/ in the browser & flash the latest firmware.

2.) Now My dreambox dm920 displays
"Rescue mode - Waiting for DHCP" by this message I will not be able to flash the latest firmware.

Please suggest.

If it waits for an IP from the DHCP, check your network and cabling... as it means the box doesn't communicate with your Router/Modem. You can always reboot your modem, generally it fixes bugs and problems as you have. As the problem is due to your network and box not connected to it... not the box itself.

You have a network problem. The "Waiting DHCP" is normal, as it requests from your modem an IP address, and waits until your modem gives one to it. It can take various minutes to obtain it.
