If basic troubleshooting fails, try putting your iPhone into DFU (Device Firmware Update) mode and attempting the restore again. DFU mode bypasses the operating system and allows iTunes/Finder to directly communicate with the device's hardware. Search online for instructions specific to your iPhone model.
