    If you saw my thread earlier about downgrading an iPod, I decided I'll skip the downgrading and I just decided I wanted to update 5.1.1. I just want to know, has anyone's device been deemed unrestorable by updating?

    Don't worry, a device is ALWAYS DFU-restorable unless there is a hardware failure.

    I know about DFU, and my iPod has no hardware failures, but has there ever been a case where iTunes will not recognize a device in DFU Mode?

    Unless there is another hardware problem somewhere, this case will never happen.

    Unless, I think maybe...
    if you do the 0x24000 Segment Overflow vulnerability and then overwrite too much stuff like the iBSS and iBEC and then when you try to go to DFU mode, it would mess up.
    IDK if that's possible, though.
    I know you can overwrite some saved bootrom data; but not sure what.

    But...
    unless you totally mean to mess up your iDevice, you can always go back to DFU

    Ok, correction: Don't worry, a device is ALWAYS DFU-restorable unless there is a hardware failure, or if you really try hard to mess it up intentionally.
