If it doesn`t work with Redsn0w then try spirit. Put 3.1.3 on it and then use Spirit ... while restoring you`ll get an error and the phone will be in Recovery Mode. To get it out of Recovery Mode simply use RecBoot from here http://www.hack2learn.org/downloads/...Tool+-+Windows and select the 2nd option to get the iPhone out of Recovery Mode. All done.
Have you tried with a different cable? Maybe there`s something wrong with that one. Try to reboot the iphone. Or with it off, hold the home button and connect the cable to it then to the PC. It`ll enter DFU mode and you should be able to restore it.
