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.
Do exactly as it says.

    After updating my iTunes it no longer acknowledges that my iPod or iPhone is connected so I can't update my music.. I have followed all of these steps and everything is working fine but this new version of iTunes isn't recognizing my devices. Any advice?

    I have the same problem. Running Win 8 64Bit, updated to latest ITunes and now will not recognize phone or pad. Followed all advice from Apple (uninstall/restart/re-install, all in exact order) ... nothing. Spoke with Apple tech and walked through the whole process, but no resolution. Tech was trying to be helpful but has no way of addressing issue.

    I am getting runtime error R6034 when trying to open iTunes I have followed all instructions for reinstalling iTunes but it still occurs can any help please?

    Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components, or run the process multiple times; this won't normally affect its library, but that should be backed up anyway.

  • HT201210 I have tried all of these issues and it still refuses to contact update server. My phone is useless right now

    I can not restore my iphone which is currently stuck in a reboot loop because the update server can not be contacted. I have tried all the remedies suggested.

    As you have tried all of the remedies suggested I guess your phone is now useless and there is no hope. But if you post the specific remedies you have tried someone MIGHT notice one that you have missed.

    least ten seconds, until the Apple logo appears.

  • TS2446 I have tried all of these steps and still says "Your Apple ID has been disabled" thats all it says everywhere. I have also tried reentering all my credit card info into iTunes and it says its invalid so I tried entering a different credit card; Sam

    I am having issues with my Apple ID and iTunes. I can log into the Apple ID with no issues on the Apple website and on my iPhone and computer but as soon as I try and do an update to my 51 Apps that need to be updated it says "Apple ID as been disabled" and I have contacted iTunes and they said that my credit card was hacked so they shut it off. So I tried to enter a different credit card in iTunes and it says invalid. But it is not its a brand new card and I have used it multiple times and there is more then enough room on that card. I am upset because this has been going on for over 6 months now and if i make a new iTunes account all my stuff will be lost.
    Please help!!

    What did itunes support tell you?
    If you did everything it says then you contacted them.
    From the article you linked:
    If the issue persists, you can visit iCloud Support, iTunes Support, Apple Print Products, or contact AppleCare for further assistance."

  • TS1277 HI. I have followed all the appropriate steps above and when I try to enter my 'Password' when asked, my keyboard doesn't work. No key press can be activated at all when trying to enter my password in 'Terminal. And I am in the 'Administrator' user

    HI.
    I am having trouble authorising my Mac Air to my Itunes account. I found a discussion explaining how to go go into 'Terminal', then adding a command. I have followed all those appropriate steps and when I try to enter my 'Password' when asked, my keyboard doesn't work. No key press can be activated at all when trying to enter my password in 'Terminal. And I am in the 'Administrator' user. Can anybody offer any suggestions?? ta

    Does the command that you're trying to enter in Terminal begin with the word 'sudo'?
    If so, your keyboard is working fine. When you type your password after a sudo command, nothing is echoed to the screen for security reasons (not even the * that are normally registered in other user interfaces). However, the program is registering what you type.
    Just type your password and press 'return' and the command will be executed (so long as you type it correctly; if you don't, you'll get an error message).

  • HT201210 i have followed all these steps and it still wont work.. any other suggestions? please help!

    Just trying to restore my phone, and i have followed all the steps yet none of them have worked. any other ways to do this?

    Placing your device into recovery (DFU) mode:
    Follow these steps to place your iOS device into recovery mode. If your iOS device is already in recovery mode, you can proceed immediately to step 6.
       1. Disconnect the USB cable from the iPhone, iPad, or iPod touch, but leave the
           other end of the cable connected to your computer's USB port.
       2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds
           until the red slider appears, then slide the slider. Wait for the device to turn off.
                  * If you cannot turn off the device using the slider, press and hold the
                    Sleep/Wake and Home buttons at the same time. When the device turns off,
                    release the Sleep/Wake and Home buttons.
      3. While pressing and holding the Home button, reconnect the USB cable to the
           device. The device should turn on. Note: If you see the battery charge warning,
           let the device charge for at least ten minutes to ensure that the battery has some
           charge, and then start with step 2 again.
      4. Continue holding the Home button until you see the "Connect to iTunes" screen.
           When this screen appears you can release the Home button:
      5. If necessary, open iTunes. You should see the following "recovery mode" alert:
      6. Use iTunes to restore the device.
    If you don't see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.
    Additional Information:
    If you have a problem getting into recovery mode then try: RecBoot: Easy Way to Put iPhone into Recovery Mode.
    Note: When using recovery mode, you can only restore the device. All user content on the device will be erased, but if you had previously synced with iTunes on this computer, you can restore from a previous backup. See this article for more information.
    If the above doesn't work, then take it in to an Apple retailer for help.

    I am trying to update my iPod touches and keep getting an error message saying iTunes could not back up my iPod because a session could not be started.  I have followed all trouble shooting advice found on the apple website, unplugged and replugged the device, restarted my computer, etc.  Any suggestions would be much appreciated.  Thanks

    I have the same issue, except I can't even sync.

  • HT1212 I just followed all of these steps, but my iPod still says that I need to enter a passcode

    So, my iPod said, "iPod is disabled, connect to iTunes"
    I followed all the steps that were listed in the "help center" but it still says the same thing in the lock screen.

    Disabled
    Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.

    If recovery mode does not work try DFU mode.

    For how to restore:
    iTunes: Restoring iOS software
    To restore from backup see:
    iOS: How to back up     
    If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
    You can redownload most iTunes purchases by:
    Downloading past purchases from the App Store, iBookstore, and iTunes Store

  • How do i fix my ipad where itunez will recognize it.. I have already followed all of the steps and it is still not working

    I have already followed the step by step instructions and i still can not get my ipad to show up in itunes

    Please describe just what instructions you followed.  Otherwise, you will likely receive suggestions to do what you've already done.
    In the meantime, try a System Reset.  It's easy, quick and harmless and it cures many ills:
    Hold down the on/off switch and the Home button simultaneously until you see the Apple logo.  Ignore the "Slide to power off" text if it appears.
    A System Reset does not remove any apps, music, movies, etc. nor does it cause any settings to revert back to default.
    Also, you might wish to download the iPad-2 User Guide.  Pay special attention to page 162.  Note that this Guide also applies to the iPad-1 with IOS 4.3 except for those functions that are not supported by the hardware.
    http://support.apple.com/manuals/#ipad
    Finally,  the User Guide can be downloaded at no charge via iBooks and a less   comprehensive version of the Guide is included as a Safari bookmark.
