  • TS3694 Has anybody had this error message: "the iphone could not be restored. an unknown error occurred (1015) ???

    the iphone could not be restored an unknown error occurred 1015

    Error 1015: This error is typically caused by attempts to downgrade the iPhone, iPad, or iPod touch's software. This can occur when you attempt to restore using an older .ipsw file. Downgrading to a previous version is not supported. To resolve this issue, attempt to restore with the latest iPhone, iPad, or iPod touch software available from Apple. This error can also occur when an unauthorized modification of the iOS has occurred and you are now trying to restore to an authorized, default state.

    Follow the steps to troubleshoot security software. Often, uninstalling third-party security software will resolve these errors.
    There may be third-party software that modifies your default packet size in Windows by inserting a TcpWindowSize entry into your registry. An incorrectly set default packet size can cause these errors. Contact the manufacturer of the software that installed the packet size modification for assistance or follow this article by Microsoft: How to reset Internet Protocol (TCP/IP).
    Verify that access to ports 80 and 443 are allowed on your network.
    Verify that communication to albert.apple.com or phobos.apple.com isn't blocked by a firewall or other Internet security setting.
    Discard the .ipsw file, open iTunes and attempt to download the update again. See the steps under "Advanced steps > Rename, move, or delete the iOS software file (.ipsw)" below for file locations.

    Mt computer has been freezing up on me lately and I think it messed up my Ipod when it quit right in the middle of downloading and got shut off.

    That's because you jailbroke your phone. You can't get help here.

    My iPhone 3GS 16gb, is stuck in restore mode, downloaded and tried to do a restore multiple times. Keep getting an error The iPhone "iPhone" could not be restored. Unknown error occured (-1). Cannot get it out of restore mode, keeps rebooting!
    I have tried to hold the "home" and "power" button to reboot
    I have tried powering it off
    I have tried, to unplug the cable, hold the "home" button and then plug it in.
    Can't check the SN or warranty, cause it is stuck in restore mode.
    Is the hard drive gone? Should there be something replaced.

    This may indicate a hardware issue with your device. Follow Troubleshooting security software issues, and restore your device on a different known-good computer. If the errors persist on another computer, the device may need service.
    Usually this is caused by your antivirus or firewall blocking iTunes access to the Internet. It can also occur if the phone is jailbroken or if the computer you are using was ever used to jailbreak an iDevice.
