  • HT1766 Iphone 5 will not back up. Getting error message and I have deleted the older backups. How do I resolve this problem?

    Iphone 5 will not back up to iTunes. I have never had this issue before but it has been consistent for the last two months. I have read a few discussion boards and restarted and deleted older backups to no success. Please help! I also tried backing up the phone to my other computer and it is still stating an error occurred.

    Its reading iTunes could not back up this iPhone because an error occurred.

  • Iphone 3gs will not turn on after attempting a factory restore

    My iphone 3gs will not turn on after attempting a factory restore, all that happens is the apple logo appears the timer goes round then stops.  It then switches itself on and off several times to no avail.
    The only way I can turn it off now is by holding the off button and the home button, but then it goes into the cycle again.
    Any advice gretly appreciated.

  • My iphone 4 will not back up when it syncs. A comment comes up stating it cant save back up to my computer?

    My iphone 4 will not back up when it syncs. A comment comes up stating it cant save back up to my computer? I have enough space on my hard drive, I have the new version of itunes and iphone software, and have tried restarting my computer several times. I ran apple diagnostics which found no issues! I'm not sure how to resolve this issue, please help me.

    I kept getting this last week. Really annoying. I found this solution:
    Remove (delete) ALL photos and videos from your iphone. Reboot it. Connect to your pc again.
    This worked for me, however I've since taken some more pics and it doesn't sync again, so I'm not sure what permanent solution there is, although I've read lots of technical ones by googling it.

  • HT4623 iPhone 4 will not back up?

    My iPhone 4 will not back up? I keep getting an error message saying back up session failed. I have tried deactivating the firewall, i have tried changing the time zone on my computer. I have uninstalled and re installed itunes. What do i do now????

    Obviously since you have iOS 7 you're a developer.  As a developer, you signed a NDA with Apple not to discuss the iOS on a public forum.  Please log in to the Developer Forum using your credentials and ask for help there, lest you risk having your credentials terminated.
    Thanks, and best of luck to you.

  • Iphone 4 will not back up on windows 7?

    My iphone 4 will not back up to my Windows 7 laptop. It either hangs up infinitely or says it cannot write to the disk. This happened on the previous version of itunes, and after deleting and reinstalling itunes it finally starting working again. After loading the most recent v of itunes it started again.  I have reinstalled itunes several times with no change.
    I am running it as an administrator and allowing it to write to the folder. I cannot update from the last ios 4.x version because it never gets past the backup step.
    Any help will be appreciated.

    iTunes places the backup files in the following places:
    * Mac: ~/Library/Application Support/MobileSync/Backup/
    * Windows XP: \Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\
    * Windows Vista and Windows 7: \Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\
    You will have to turn on "Show All Hidden Files & Folders" to see them. Navigate to that backup folder & delete the entire contents. Try again after doing so.

  • HT4910 My iPhone 4 will not back up to iCloud! Help please!

    For some reason my iPhone 4 will not back up to iCloud when I press the back up now button in settings.

    What happens when you try?

  • HT4489 My iphone 4s will not back up my contact list to the icloud.  Not sure why!!  any ideas?

    My Iphone 4s will not back up my contract list to the icloud.  Not sure why?  Any ideas.  I have tried everything!

    Welcome to the Apple Community.
    I assume you mean sync, not backup.
    First check that all your settings are correct, that contact syncing is checked on all devices (system preferences > iCloud on a mac and settings > iCloud on a iPhone, iPad or iPod).
    Make sure the contacts you are adding are added to your 'iCloud' group and not an 'On My Mac', 'On My Phone' or other non iCloud group (you can do this by checking in groups), non iCloud contacts will not sync.
    If you are sure that everything is set up correctly and your contacts are in the iCloud group, you might try unchecking contact syncing in the iCloud settings, restarting your device and then re-enabling contact syncing.

  • Iphone 4s will not back up

    My iphone 4s will not back up to icloud.
    Storage informs me I have 4.7 GB free from 5.0 GB.
    I see nothing at icloud on ANYTHING.
    I have just gone through the menus on the phone and hit backup which started.
    Informed it would take about 40 mins, but stopped after about ten
    Anybody had same problem, and how was it fixed please.
    Would be most greatful
    Thanks

    Thanks for that.
    Thought it was ment to be an automatic thing.
    Just press "Back-up Phone" and off it went up to icloud.
    No such luck.
    Marketing people just tell you any old rubbish.
    It would be ok if they said "You have to do lots more to get it to work", but they don't.
    Bit like Microsoft
    Settings on icloud on my Mac will not set photos to back up, or import to iphoto on the Mac
    Seems I need to update iphoto at £10.99. More expense.
    If I did not have a Mac, would it back up the photos to icloud I wonder.
    Looks like I might buy Photoshop, forget about icloud, and use Google Drive or Drop Box instead.
    Thanks for your help

    My iPhone 5 will not sync as i need iTunes 10.7 but this will not download as i have OS 10.5.8

    You need to upgrade your OS to this:

    From there you upgrade iTunes, & you'll be able to sync your phone.

    - Try another USB port.

    My iPhone 4 does not ring only vibrates. I have restored but no luck. Ringtones can be heard through speaker during selection. Ring volume is also set at maximum.

    I had the same problem. I took the phone to the local tech shop and they replaced a fried headphone flex cable. Cost me $70.
