    Try to restore your iOS device two more times while connected with a cable, computer, and network you know are good. Also, confirm your security software and settings are allowing communication between your device and update servers. If you still see the error message when you update or restore, contact Apple support.

  • "the iphone could not be restored an unknown error occurred (2)"

    Yesterday I connected my iPhone 4 to my Windows 7 laptop, and went through to install the latest security update for iPhone through iTunes. When it was installing the software update, the phone froaze, and then this happened:"the iphone could not be restored an unknown error occurred (2)"
    Now, I have uninstalled and reinstalled both Bonjour and iTunes, to no avail. I have done the iPhone reboot method, and the phone will be identified as "iPhone" but not recognised as mine. iTunes states this phone is in recovery mode and I have tried numerous times to restore it.
    Windows doesn't detect the phone while this is happening. It will not restore and the error is still popping up. I have followed as many threads to rectify this but nothing seems to be working.
    I can resore it on my iMac but the reset date for the iPhone on this computer is six months old.
    Any suggestions?

    When you say you uninstalled iTunes and reinstalled it, did you follow the directions in this Apple support document exactly? http://support.apple.com/kb/HT1923
    That will make a difference on Windows computers. After that, try and reconnect and restore.

    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.

    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.

    Instructions to get the phone back working temporary.. till there is a real fix.
    1. turn off the phone
    2. fire up iTunes
    3. press and hold the home button, plug in the cable, hold till you get to see the recovery mode
    4. iTunes will the allow to choose restore the phone back to 5.0.1 ( no other choice)
    5. iTunes will then ask you to choose which previous backup to would like to recover.
    (note: please do not reboot your phone unless necessary, i realize at times after reboot, it goes back to sq1)

    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.
