Thread: An Unknown error occurred (21)

  1. #1
    Default An Unknown error occurred (21)
    i tryed upgrading to the latest firmware and my phone has just messed up compleatly

    i have upgraded and downgraded to every 2.0 virmware and none will load n all of them will come up with An Unknown error occurred (21) when i load up custom firmware

    ive tryed using pwnage for mac, quickpwn for mac (but i cant get the timing right on that) along with winpwn but everything seems hopeless i cant find anything on google about An Unknown error occurred (21) or how to resolve it but nothing seems to work

    i own a powerbook g4 if that helps but also have access to a pc

    might have to buy a bloody hypersim

    having a phone which is praticaly a brick sucks

    This same thing just happened to my iPhone 3G with the 2.2 upgrade.

    Any help would be more than appreciated.
