Got the dreaded "sync session failed to start"
OS 10.6.8, iPhone 4, OS 5.01, iTunes 10.5.1 (42).
Woke up this AM to find my iPhone battery completely drained (never happened and have no idea why). Charged up to halfway and did a sync. Sync session failed to start.
Used my regular user, etc. Had synced only a few days ago.
Never have seen this problem, ever.
Tried a restore (twice) nothing changed. All I have in my phone now are contacts and base apps. Nothing else.
No issues with iTunes of my computer, though I did notice while doing a restore a couple little squiggles of garbage text (very small in gray) up the the left of the software install box.
Do I have to submit to a complete uninstall and install of iTunes (not the easiest to do) to enable the phone to eventually sync correctly again?
Read through other posts on this topic and most were on Windows machines, though I tried by deleting the last backup (no luck) The last full back up I have is one from Aug 2009 (when I bought this phone).
Should I delete all backups? and try again?
Was this related to the severe battery drain?
TIA
Think I fixed it.
Tried the oddest suggestion yet from another thread on this same error message and it seems to have worked!
Went to:
Settings => Phone => My Number
in my iPhone and deleted the +1 front of my phone number. Phone is now syncing as we speak.
Is this a bug with the new OS?

My wife dropped her iPad2 last week. Since then one of her apps is not working correctly so I thought that I would sync the iPad because it has been a while. When I plugged it in to my desktop computer through USB, I got the message "Failed to sync because the sync session failed to start." I have never seen that message before and I am not sure what I can do now to sync my wife's iPad. Any suggestions and/or help would be appreciated.
I realize your device is different, but the solution will probably be identical. Read this thread:

Pretty much as above, when I plug my iphone in it just comes up with the message saying the sync session failed to start and thats all I can get out of it :/
Any ideas on what I need to do to get my iphone to talk to my itunes again please?Hi hblower,
As a first step, I would suggest quitting your open apps:
iOS: Force an app to close
http://support.apple.com/kb/ht5137
Then sign out of iTunes:
iOS: Changing the signed-in iTunes Store Apple ID account
http://support.apple.com/kb/HT1311?viewlocale=en_US
Restart and/or reset the device:
iOS: Turning off and on (restarting) and resetting

Are you running the latest version of iTunes? If not, update the software and try syncing again …
Cheers,

"The ipod could not be synced because the sync session failed to start" What does this mean?
When syncing on iTunes, the syncing meter runs in iTunes in my computer but nothing appears in my device (It should have Sync In Progress). Whenever I edit my music files (editing title, album and artwork), it edits in iTunes but when I eject my device, nothing's changed. My device is a 3rd Gen iTouch and this is my second 3rd gen iTouch unit. I lost my first unit and am familiar with how it operates so I do not understand what is causing this. The 4 view option buttons "show items in a song list... etc" (beside the search field, upper right corner) won't work. Now in my 3rd attempt to sync, as i right click on my ipod name in iTunes to select sync, this appears ,"The ipod could not be synced because the sync session failed to start" and my only option is to click OK. Please help. My apps are kinda slow too and theres a slight delay opening files and apps in my iTouch.
Try this previous discussion:

IOS 5: The iPad "..." could not be synced because the sync session failed to start.
Am trying to migrate into the iCloud and updated:
1. Mac Air to 10.7.2
2. iTunes to 10.5.(141)
3. iPad (1) to iOS 5 (9A334)
Was able to sychronize and then found out I lost all my apps and rearranged them in iTunes and hoping I could resync them again and received:
The iPad “...” could not be synced because the sync session failed to start.
I saw various entries for this in the the communites mainly caused by earlier Betas but I haven't seen anything for the latest versions released last week.
Anybody who can help?Try resetting your iPad an see if that will let you sync.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
Try restarting your computer as well. -

Hello brainiac08
Typically that error occurs because of a backup issue. Check out the article below to resolve it.

I'm trying to sync my iPhone4s, but everytime iTunes tries to sync, I get a message "This iPhone cannot sync because the sync session failed to start." I've tried restoring my phone, and all my software is up to date. It won't sync any of my songs/apps back to my phone. Somebody please help!
Try to connect in recovery mode, explained in this article:
iOS: Unable to update or restore
Before that, back up your device, explained here:

Whenever I try to sync my iPod Touch 5th gen with iTunes I get an error message saying "The iPod "*****" could not be synced because the sync session failed to start". Is there any way I can fix this?
B-rock, thanks for posting the above. I actually have the same issue, running Windows XP and I don't have that backup location, \Application Data\Apple Computer\MobileSync\Backup\. When I go to Documents and Settings\(username)\ there's a AppData folder followed by:\LocalLow\DataMngr\ .
I have the latest update, 5.0.1 and I have the iPod Touch 3rd gen.
I have tried removing itunes and all that is associated with it then reinstalling and keep getting the same message. I've reset my ipod thinking that would help but still, no backup.
In iTunes, Edit, Preference, Device there are no backups.
What am I doing wrong, can you help?
Thank you! -
I am getting an error message when trying to sync to my PC that says "The Iphone could not be synced because the sync session failed to start" what setting is messed up?
The way I fixed this (though I'm using a iTouch 4G): disconnect your iPhone from the computer, shut down iTunes, then reset your iPhone by holding the Power/Sleep & Home buttons together for 10 seconds. Restart iTunes, then when your iPhone restarts, reconnect it to the computer, and everything should work fine
