Is this your issue...
Activation Lock in iOS 7  >  http://support.apple.com/kb/HT5818
If so...
The Apple ID and Password that was Originally used to Activate the iDevice is required
If you do not have that information you will not be able to use the Device.
There is No workaround.

  • Can you restore to factory from a different computer then restore backup from the original computer?

    My son reset then forgot his passcode, when I try to restore from his computer his pc freezes. I have tried several times and continues to freeze. He does not want to lose his contacts, purchased songs and apps but all else does not really matter.
    So, am I able to restore his touch from my computer then restore the backup from his computer?  It did complete the backup on his PC.
    Please help, we have been messing with this for a few weeks now and I am just tired of trying to restore when his pc keeps freezing...

    Yes, just plug in into iTunes and it'll give you the option to restore as a new device..

  • If I backed up with a newer version of iOS than the phone I am trying to backup to.. Is there any way to bypass the setup assistant in order to download the new iOS on the new phone then go back and restore from my old phone?

    Try deleting your last backup by turning off iCloud Backup in Settings>iCloud>Storage & Backup, then tap Manage Storage, swipe across your backup and tap Delete, then go back and turn iCloud Backup back on again.  If it still won't back up, you may have an app that is preventing the backup from succeeding.  To locate which one, go to Settings>iCloud>Storage & Backup>Manage Storage, tap the name of your device under Backups, under Backup Options tap Show All Apps, then turn them all to Off (including camera roll) and try backing up again.  If it succeeds, then the camera roll and/or one of your apps is preventing the backup and you'll have to located by process of elimination. Turn the camera roll On and try backing up again.  If it succeeds, turn some of your apps to On and try backing up again.  If it succeeds again, turn some more apps to On then try again; repeat this process until it fails.  Eventually you'll be able to locate the problem app and exclude it from your backup.

  • I recently tried to update IOS on a work computer not logged in as an administrator, this wiped my phone and put it in safe mode. I restored from a different computer but now need to back up from the work computer but dont want to"restore" to get contacts

    Itried to upgrade my software at work which failed and wiped my phone . It then wouldnt restore either and put the phone in recovery mode.
    I installed a new version of itunes on a home computer and restored my phone but it now has none of my contacts apps photos etc.
    How can I get this back from my work computer without restoring as this will fail again. Is there anyway of sending my backup from my work computer to icloud and backing up from there?
    I think the issue is that as I do not have administrator rights at work so  the restore/backup fails each time.

  • HT201263 Please help, I'm extremely frustrated.  Have 4th G ipod touch stuck in recovery mode.  Tried connecting to another computer to restore.  Goes through 75 minutes of ipod software update then get a Problem downloading.  Network connection timed out

    Please help, I'm extremely frustrated.  ipod is stuck in recovery mode.  Connected to different computer to restore and after 75 minutes of downloading get a message that there was a Problem downloading, network connection timed out.  Cannot get past "connect to itunes" on ipod.

    Disabling the computer's antivirus and firewall during the download and update usually resolves that error.

  • Is there anyway to restore an iphone to new from a different computer and then use a backup from the cloud?

    Is there anyway to restore an iphone to new from a different computer and then use a backup from the cloud? At&t said that they unlocked the phone but that it needs to be reset in itunes and retored for it to work. However, I do not have access to my computer as I am overseas and need to put a new sim card in. Anyone had this problem and know a way to go around this?

    If you have an backup on iCloud. You can restore via iTunes (on every computer) or via your iPhone itself.
    And yes, you can restore the backup via iCloud.
    To set iPhone to new do this: Settings > General > Reset > Erase all data and Reset all Settings.
    It take a while. But after this, you can restore backup via iCloud.

    i am getting the following message "safari could not download the file (440 MB) because there is not enough disk space.  please delete files or download to another disk."  when i check system information it tells me i have 249.82 GB of disk space available.  any suggestions as to what i can do to resolve this problem.

    don
    thanks for your suggestion.  that is the same advice that i got from the geek squad at the local apple store.
    i did what he instructed but it did not work.  i have since called apple support twice regarding the problem.  they had me start the computer in safe mode, going into the library and deleting a phlist file (i think) do a repair disk permissions, do a repair disk, empty the cache, and finally the last guy told me to unplug the computer from the wall socket and restart.
    when i mentioned the advice you and the apple store guy gave me they sort of poo pooed it saying that was done when they did all this other stuff.
    i am now waiting for the download to be completed to see if unplugging the computer had any effect.
    thanks again for your kindness in answering my concern.

    I've tried and tried several times to Connect my device to my PC and follow the onscreen instructions in iTunes to download the update from Apple. Problem is iTunes doesn't connect to my iPad so that I can update to iOS 5. I don't see the iPad icon when iTunes loads. I have looked in my computer and see the iPad is recognized. Any one else having this problem? This is also happening with my iPod
    Thank you, Ripley

    I haven't updated yet. Apple's download servers have been too busy. Did you know you can update via wifi instead of connection to your computer?
    Here's a description of the update. Not a lot of changes for iPad 1/2.
    iOS 5.1 Software Update

    You can wait a while & update at your convenience.

  • I bought an iPhone 5 yesterday and every time I try to restore my iPhone, I get error 21. I've tried numerous times and have tried things on the internet but still no luck. I have the latest iTunes update, anyone have any suggestions?

    Please help!

    Or the OP could try actually following Apple's documentation for troubleshooting and solving this very simple problem instead of uninstalling, reinstalling, installing old versions of software, etc...
    https://discussions.apple.com/docs/DOC-3141
    Error 20, 21, 23, 26, 28, 29, 34, 36, 37, 40
    These errors typically occur when security software interferes with the restore and update process. FollowTroubleshooting security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
    Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See iTunes: Advanced iTunes Store troubleshooting—follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store. If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart.

  • Updating my Iphone 4 then it said error 1604 and now keeps saying that when i try to restore it

    is there anything i can do or do i have to take it to apple?

    I had exactly the same problem. It happened today after I upgraded to Lion and the latest version of iTunes.
    Then I did some search on the net and got a solution and was able to restore.
    What you need to do is, connect your iphone to a different USB port on your system, make sure it isn't connected through a USB hub, only connect directly. If that doesn't work change the USB cable you are using and try again.
    Good luck.
