Bricked WNDR3800 returned to life.. But not fully functional

Hi! Sorry for my english..

I've bricked my WNDR3800 and ONLY with a TTL-Usb serial cable, i can put a stable firmware on it.

All the nvram variables are blanked!! the ssid, mac, board_id, etc.. etc.. .
Only when i changed the nvram variable "hw_board_id", i can tftp a Netgear stock firmware (1.0.0.38).. And it seems to work..
I try to correct the mac addresses with the ones printed on the router's back. But my wireless still does not work.

I think some other variables are lost and is needed by wireless interface.

There is a way to recover the standard nvram values of WNDR3800?

Thanks
