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
http://support.apple.com/kb/ts2529
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,
