As I understand it, DFU mode simply avoids loading the resident OS and puts the Touch in a mode that is ready to accept an OS installation. If you're successful in getting into DFU mode, it would show up in iTunes as an iPod in recovery mode and you would then restore as usual to install the OS.
This is not exactly the same as DFU mode (some people refer to it as a force-restore):
1. Launch iTunes but do not connect the Touch.
2. Hold down the Touch's Home and Sleep buttons at the same time. This will force the Touch screen to fade and the Apple Logo to reappear. KEEP holding the two buttons down until the Touch's screen goes black.
3. Once the screen is black, release the Sleep button but *keep holding down the Home button* while you plug the cable into the Touch. Contunue holding the Home button until the you see the iTunes logo and the picture of the cable on the Touch screen. This may take up to 30 seconds.
4. iTunes should now detect the Touch and you can perform a Restore.
One other thing is to delete the OS file from your computer, so that when you restore the iPod it will download a fresh copy. You can find the .ipsw OS files at:
PC: C:\Documents and Settings\(account name)\Application Data\Apple Computer\iTunes\iPod Software Updates
Mac: Library/iTunes/iPod Software Updates
The filenames are a little cryptic, but you should be able to figure out which one is 3.1.3.
