Sync session fails to start on iOS 5 and iTunes 10.5

It has been over 24 hours already as i try to sync from iTunes 10.5 to my iPhone 4 with the new iOS 5.
Phone works fine with the apps and other features but syncing seems to have a problem.
It says that the iPhone can not be synced beacuse the sync session couldn't be started. Anyone with this same problem? Need help.

I am having the same problem with my new upgrade iphone 4S with the sync failing to start. It was working ok on Friday, but started having problems on Saturday. Of course after I move all my apps into where they I wanted them in different folders - took hours, then had to get out of the computer. Reverted to what was on the phone. Tried it again this morning, at least did not do all the work I did the first time - same problem. Do you think this is a problem because of iCloud? I do not have that.

"Sync Session failed to start" when connecting iPhone to iTunes

Help?!?!

Hello noraa311
If you are seeing an alert error about not being able to start the session, tends to be an issue with backing up. The article below will start you troubleshooting and resolving the issue.

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.

Sync session failed to start in iTunes after updated to iOS 7

Restart your computer
While your computer is restarting, clear all of the applications from the background on your iPhone. You can do this by pushing the home button twice and swiping the programs off the screen by pushing them upwards.
After you are done doing that, restart your phone.
Wait about 10 seconds or so and turn your phone back on. By the time you get your phone back on your computer should be completly restarted and ready to go.
When your phone is back on, plug it into your computer. This should automatically bring up your Itunes, you may get another pop up that says autoplay, you can close that out. That's it. I hope it helps and good luck

Okay, so my friends think it is funny to change the passcode on my iPhone.
Maybe you should get new friends.
I'm not sure that recovery mode works when you have to trust the computer, but did you try it?
If you can't update or restore your iOS device - Apple Support
If that won't work, perhaps you can use Find my iPhone from a computer in your iCloud.com account to erase the device.
iCloud: Erase your device - Apple Support
This has nothing to do with the Find my iPhone app being installed on the phone, but you do have to have Find my iPhone activated in the iCloud settings on the phone.

HT1296 My iphone wont sync and all I get is a message saying that the sync session failed to start, any ideas on what I do next?

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
http://support.apple.com/kb/HT1430
Are you running the latest version of iTunes? If not, update the software and try syncing again …
Cheers,

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. How do I fix 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:

Error message help: "The iPod "CKK's iPod" could not be synced because the sync session failed to start."

I get this error message when trying to sync my iPod Touch, "The iPod “CKK's iPod” could not be synced because the sync session failed to start."

Just made one very simple move without having to restore iPhone or reinstall iTunes..
1st step:http://support.apple.com/kb/TS1538 *Read 'in my case' in here first before following this link*
Follow that link to restart (or if necessary) reinstall your Apple mobile device support.
In my case, Leave iPhone connected all the way. I first exit iTunes. Then i stopped the Apple Mobile device support (by following a part on that link above in step 1) which Effectively made my iPhone undetectable on itunes but discoverable by windows as a 'camera device'. Then while device is still connected, i started the Apple mobile dev support again. Now i open itunes and there my iPhone re-appears.
2nd step: After your iphone re-appears on iTunes, press Sync and all is well...
P.S, Mine is iPhone 4 running on iOS 5, iTunes 10.5, Windows 7..

What could be the reason when to get sync session failed to start message. I have upgrades to IOS5 but seemed to have no problems

I had upgraded nearly 1,5 month ago to IOS 5.0.1 and seemed to have no problems during the process (all my aps and books retored fine).
However suddenly today i-tunes says it can't be synchronizes (starting 1/7) because sync session failed to start.
I've tried also with WiFi sync but was always trying to restart syncronization.
I've runned the i-tunes diagnostic for sync and said it passed.
Could be H/W problem with my ipad?

One post said to delete previous backups which did not resolve the issue.
One post said to re-install which, also, did not resolve the issue.
Any help would be greatly appreciated.

Try using a different USB cable. If you're using a desktop, make sure you're plugging the USB into the back of the computer, not the front

Cannot sync. Error message says "sync session failed to start"

I am not able to sync my ipod. The error message "the ipod could not be synced because the sync session failed to start" keeps popping up. I have tried both syncing it plugged in and by wifi and the same message appears

Same problem today. Took five times to reinstall without any error messages. Apple has posted a way to fix and you should follow their's first. I finally got to upldate correctly by doing their fix but with one difference. I did the following:
1) Went to the C:\program files (x86)\iTunes and C:\program files\iTunes folders and moved every file ending in .dll to the desktop (even if two files in same location had the same name, just replace)
2) Restarted computer and still got error message
3) Uninstalled all apple programs possible in the following order......itunes, apples software update, apple mobile device support, bonjour, and apple application support.....all performed using the microsoft control panel
4) put all the .dll files on the desktop in the trash and emptied (this is a step apple support did not specifically put in their fix but for a final try I wanted to delete everything apple).
5) Restarted computer.
6) Re-installed itunes from apple website
No error messages during re-install and was able to open shortcut in one try. Even updated my ipad to make sure everything was working.
