Hi,
i got a WRT54G v 3.1.
There was a custom DD-WRT on it, but the owner forgot the password.
Now he ask me to flash a openWRT (openwrt-wrt54g-squashfs.bin) on it.

Press the reset Button for 30 sec. did not help.
The WRT54G hold the Custom IP: 192.168.90.x

NMAP Output of a scan the WRT54G

you can use serial connection. see article port.serial in the wiki for more information.

for more information on the dd-wrt recovery mode you should consult the dd-wrt forum.

thanks, but no other chance to reflash without know the password ( no serial cabel ) ?

in openwrt you can login over serial connection without the need of a password. Also, in recovery mode, it is possible to get telnet access, which does not need a password, either. but as mentioned already, I don't know about dd-wrt.
