Q: When syncing my iPhone, iTunes says the sync is unable to start?

As soon as I plug in my iPhone, it begins to sync. The last three days it says the iPhone could not be synced becasue the sync session failed to start. I do not understand why, I have not done anything different from the last two years I have had this phone?

iPhone 4S, iOS 7.1.1

    Hi daynja,

     

    I understand that when you connect your iPhone to iTunes and try to sync you are getting an alert that the sync session failed to start. I suggest looking at the following article and going through the operating system specific steps depending on if you are using Windows or Mac OS X. If you are using Windows, I would be sure to follow the steps in the Resolution section.

     

    iOS: If you can't back up or restore from a backup in iTunes

    Symptoms

     

    When you try to back up your iPad, iPhone, or iPod touch or restore from a backup, you may see an alert message in iTunes that your device couldn't be backed up or restored for one of these reasons:

     

    • "... the backup session failed."
    • "... a session could not be started."
    • "... the iPhone refused the request."
    • "... an error occurred."
    • "... an unknown error occurred -1."
    • "... the backup could not be saved on this computer."
    • "... not enough free space is available."


    Resolution

    If you see one of these messages or a different message, follow the steps below. If iTunes for Windows stops responding or the backup never finishes, follow the steps to fix performance issues.

     

    Thanks for reaching out,
