    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.

  • HT4061 trying to restore a 3gs. keep getting 'activation server is temporarily un available'

    trying to restore a 3gs. keep getting 'activation server is temporarily un available'

    Generally this is a sign that the iPhone had previously been
    hacked/modified/jailbroken and the update relocked it to the
    original wireless carrier. If this is the case, only that wireless
    carrier can unlock your iPhone. You must contact them to see
    if they offer unlocking and if you qualify.
    What wireless carrier did you use before this problem?
    Does the app Cydia appear on your iPhone?
    What does it say when you look at Settings=>General=>About=>Carrier?

    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.

  • Tried to update ITunes, but keep getting error: Service "Apple Mobile Device" failed to start. Verify that you have sufficient privileges to start system services". How do I get my ITunes back?

    Tried to update ITunes, but keep getting error: Service "Apple Mobile Device failed to start.  Verify that you have sufficient privileges to start system services."
    So how do I get my ITunes back? 

    Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
    Remove all of these items in the following order:
    iTunes
    Apple Software Update
    Apple Mobile Device Support (if this won't uninstall move on to the next item)
    Bonjour
    Apple Application Support
    Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
    The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
    Please note:
    Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

  • My Ipad 2 won't restore and I keep getting error 14

    So today I decided to finally update my Ipad 2, it was 4.1.3 I believe and the newest update was 7.0.4 . After backing it up and waiting for the long update, suddenly it asked me to restore it. So when I try to restore it, my Ipad turns on and it will show the apple logo with the loading bar, right after that a message pops up in my computer saying that it cannot restore and there's error 14. I don't know how to fix this when I unplug it, it asks me to plug it to itunes since its in recovery mode but i keep getting error 14, help please.

    Check for hardware issues
    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 alert when you update or restore, contact Apple support.

  • I am not able to restore my iphone 3g. getting error 1015. please help

    Hi,I have forgot my iPhone 3G password. Trying to restore with itunes. but got error 1015. cannot resotre. Kindly help.

    Hello Jeetendray,
    For error 1015, that deals with a few different factors like having a beta version of iOS, downgrading, and potentially jailbreaking your iPhone. I would recommend trying the restore on another computer or just a different user to download a fresh copy of iOS for your iPhone.
