After installing the dd-wrt mini firmware got a brick. Lights amber, no ping, says that cable is not connected, all the ports do not answer(tried other cables). Booting stops, but the tftp runs through the console or by short pins(flashing green).

Is there a way to load the firmware without a network cable?

Sorry for bad english.

The console responds this:

Decompressing..........done
