iTunes Cancelling Sync

Same issue here, has anyone else managed to solve this? Its been happening since iOS7 and not been fixed thourgh all updates including 7.1

I had this problem also. Some other attributes of the problem:

• My music's play count was being incorporated repeatedly on every sync attempt which led to the play counts increasing dramatically and incorrectly.
• Couldn't add new music to my device.
• Couldn't update other content types

ANYWAY, to solve this:

I restored my phone to factory settings with iOS7.1, then restored from my most recent backup (which I'd taken a short time before the restore process).

BEWARE that there's a risk while doing this for your content. At least one applicaction (Livescribe +) had it's data file corrupted after the restore. Though I have no way of knowing whether that was a consequence of this restoration or cooincidental.

24 hours later and I've been using the phone and everything is working fine. My sync's complete and my content is updating fine.

I had this same issue and found that one song was corrupted and iTunes was canceling the sync once it arrived to this particular song as a precaution. It took some weeding through, but I found which one it was and that alleviated my issue. Hope this helps!

How did you find the corrupted song, Mr_Vintaje?

It was a time consuming process, just so you know, but I started adding albums individually instead of all at once, then when I added this one particular album...I would cancel the sync. So that let me know that something on that album was corrupted, then by adding songs one by one from that album, I found the corrupted song and deleted it. iTunes is my friend again! Like I said, it is a very time consuming process, but it is over now and I am glad to have my iTunes back! Lol

Wow - thanks for the quick reply! I was afraid that was what you meant :-/ But how do you select individual songs? I only see the boxes containing check boxes for Playlists, Artists, Genres and Albums ...

You can also add music to your iPod by dragging it from your Music Library tab at the top left...above your Devices section. When you are in your music library, just click and drag any one song you'd like to your connected iPod in "Devices". Once, I narrowed it down to the album, I added one song at a time and once I got the "Canceling sync" message I knew it was that song and deleted it. It takes time I know, but you will feel like an Apple Genius once you've found the culprit! Lol I hope this helps Levin!
