This will take ages (2 minutes)! If you want a

status bar: Attach a serial to the device and look there.
|

|

Note: If this fails, you need to use AVM\' recover
|

utility to get your box back. However this step
|

should not damage your box....
|

|

Also it doesn't terminate.. :/

(Note: Make sure that you connected the router on

the yellow LAN ports and not the blue WAN).
