Need help with my hacked HomeHub

[#1]

Hey
A few weeks ago I downgraded the firmware on an old HomeHub so I could use it as a backup router or repeater or something on another ISP (Plusnet).  BTW I can dig out the guide for doing it if anyone is interested.
All went as planned, and it seemed to be working fine.  I tested it for the first time on my new Plusnet connection last night, however, during the 'Setup' it kept timing out.  It never said 'couldn't connect' or anything like that.  I would have thought it would work with Plusnet because it's basically a Thomson router with version 7G firmware I think.  Also I had to hard reset it because it changed the admin pasword and I couldn't remember it (it wasn't default).
Has anyone got an old HomeHub working on Plusnet?  Why would it keep timing out on Speedtouch Setup Wizard?
Thanks

Hi Superhans,
You may wish to see what other replies yo get but I just wanted to mention from a support point of view that its normally a firmware issue when the setup wizard hangs like that. I would try another hard reset of the router then failing that maybe flash the firmware again.
If you don't have any joy at all we can offer you a brand new Thomson T585 (version 7) free on a 12 month deferred contract (meaning that you would pay the full cost of the router if you left within that period) you would just need to pay £4.99 postage and packing and we can get one to you within a couple of days.

Thanks Adam,
I tried a hard reset to no avail.  It doesn't matter though.  I only wanted the HomeHub as a backup, I have a Linksys WAG160N that I use now.
