Okay, before my iPod Touch 1G was fine. I had jailbroken it on firmware 2.2, but then I decided to give my iPod Touch a clean wipe so it would be smooth again. So, after restoring to original 2.2 firmware, I download the PwnageTool for 2.2 firmware, created an ISPW (2.2 jailbroken), and tried to put my iPod Touch 8GB 1G into DFU mode, but it didn't work. I did the shut power off completely, hold home+power button 10 seconds, release and continue to hold home button for 10 seconds. Then in iTunes, it says "Waiting for iPod..." and for a minute it says that, finally, it says that the iPod was detected but something was incorrect or something like that. It was error 2001. So I had to reboot my iPod Touch. For some reason, I can't go into DFU mode anymore. Btw, I'm using an iMac Leopard.
