Q: ipod touch wont update software

Are you trying to update it via iTunes? If not, then that is the problem. You must update via iTunes for any IOS under 5.0, and the iPod Touch 2nd Gen can only go up to IOS 4.2.1.

Cheers,

When you go to Settings>General>About on your iPod, what IOS version does it say you have?

What exactly is the error you are recieving?

Hi,

Not finding an Unknown Error (-1). Are you sure the number is -1?

GB

Well, not sure then. No hits on that error code.

Could be one of a couple of things:

iTunes is not up to date?

iPod is jailbroken?

There just are no posts anywhere on an error -1 that I can find. One last thing you can try is to reset the iPod:

Hold down the Power and Home buttons at the same time and continue to hold them until the Silver Apple appears. Then try to update again to see if that fixes the issue. If that does not fix it, and neither of the other things is a possiblity, then I am at a loss....

Sorry,

GB

Error -1

Attempt to restore your iOS device two more times. If the issue is still unresolved, the device may need service.

The "device may need service" means a hardware problem. In that case make an appointment at the Genius Bar of an Apple store.
