I upgraded to 1.1.3 from a jailbroken 1.1.2 and have successfully downgraded to 1.1.1 using the hold home+top button while connected to iTunes to restore before. I have done it several times actually. This most recent time, Google Maps wasn't working on a jailbroken 1.1.3, so I decided to just go back through the whole process again to get a fresh copy. However, now when I'm connected to iTunes and hold down home+top, it doesn't work. I hold both buttons until the iPod turns off and release the top button while still holding down home, but then nothing happens. It usually takes about 10 seconds or so but I have tried holding it down for up to 3 minutes and still nothing. iPod still looks off and iTunes doesn't detect an iPod in restore mode. So basically, I can only use it as a standard jailed 1.1.3 iPod and can't downgrade to any previous firmwares. Any suggestions?
