Are you putting the iphone in DFU mode? Before you restore hold the power and home button for 10 seconds then the home for 10 seconds, thats all I can think of, otherwise uninstall then reinstall itunes.
Edit:
Also try it on another computer if possible.
Also try and use ibrikr I think that can be used to downgrade (enter DFU)
Finally try and downgrade to a lower firmware e.g. 1.0.2 first
