I have upped this too share. http://www.mediafire.com/?7078z7mnk1k61lr
I remember it took me ages to get hold of few years back and I had to join some website and get approval before I could download it, it was the only place on the web I could get it, I dunno if its easily accessible now, anyway I ripped it and shared itthis allows you to use a Speedtouch Router (that has been locked out with ISP firmware) with any other ISP , it installs settings that are inaccessible on such ISP Firmwares.
- it can also upgrade firmwares but I could not get it too overwrite the ISP's firmware with Speedtouch firmware, maybe its possible if you rename the firmware file name to one used by the ISP
I used this on my Speedtouch 585v6 which was locked to Tiscali and set it up to work on my sisters talk talk - there is a list of routers it works with.
