[OpenWrt-Users] no SSH access to ASUS WL-500g Premium with OpenWRT: howto restore Original Firmware?

[Sven]

Hi all

I have here a ASUS WL-500g Premium box which was flashed with OpenWRT 
(according Nmap). This was done by somebody else.

The big problem is that all 65535 ports are closed. So how to restore 
original firmware?
