    stuck on start up screen. When restoring itunes gives unknown error. when jailbreaking its stuck on replacing kernel.

    Problem came about when I deleted all data and settings from a jailbroken iphone.

    Jailbreak: Redsnow latest
    operating system: ios 4.2.1
    itunes 10.something

    Best way is do download the desired IPSW to desktop,
    They are all available on the iPhone Wiki

    Use Redsn0w to put the phone in pwnedDFU mode (DFU would also work)

    If restoring to 4.2.1, make sure host file point to Apple,

    Use iTunes to navigate to to your IPSW (Restore button plus shift-PC, option-Mac)
