I ended up here yesterday looking for a fix to the same problem - with a 10 month old San Francisco II - after a dance between Orange and ZTE call centres I was directed to the zteuk.co.uk site, where there are download links for the driver update tool.
The first run through, I got the same problem as RedG - phone not known and no chance to update software. After closing the updater and running it a few more times it suddenly decided it need to go and get an update - the updater update process failed, so I retried that a few times until it finally succeeded.
Finally, the updated-updater recognised the phone and went and downloaded new firmware and began to update the phone itself. Of course, that process failed at first, but trying a second time succeeded - and finally, unbelievably - the phone rebooted! All data gone of course, but at least the phone is no longer a brick.
BTW, I think the key to getting the updater to try to update itself was closing it properly so it no longer appeared in the task tray, otherwise I think it sits there looking for the phone and not restarting and checking its own status.
So the summary if you have this problem - grab the software updater, and keep trying until it succeeds!
Hope this helps someone...

Hey there, I've had the same problem as above. I used the link and downloaded the handset software update tool. I put my phone into FTM mode and ran the updater. however I get the following information:

This mobile phone cannot be supported to update currently, thanks for your use.
