    I think people that experience this problem fall into one of two categories:

     

    1. Intermittent failures that are typically solved by restarting,etc.

    2. People that can not start a sync despite the simple tips in this thread.

     

    I was in the latter category. Until I did a clean restore of the entire device, I couldnt sync. Then sometimes minutes, sometimes days later, I would again not be able to sync, and no simple remedies worked. Only anothe full restore would allow syncing again.

     

    I think I finally figured out my issue. I was also having a problem with itunes match. A number of people have seen a similar issue where empty playlists get duplicated thousands of times. I had 67,000 emoty playlists. Turns out they were all synced up to icloud, so even after a restore (as above), they would come back. I finally got rid of the playlists by using a script that deleted them one at a time (took like 8 hours). If you have this problem, once the script finishes, be sure to allow itunes to run for a while to syn all the local deletes to icloud. I made the mistake of not waiting long enough, and 5000 came back. After subsequently removing them cleanly, I hae not had any problems syning. Certainly could see why 60,000+ playlists might cause the sync process to vomit.

     

    After a month of this nonsense, I am finally free of the playlists and syncing reliably.

    If you'll reset the lockdown folder it works perfectly and I haven't had an issue yet.

    Isn't the lockdown folder a Windows feature?  Is there an equivalent in OS X?

  • brandycmc Level 1 (0 points)

    The answer to that, Bob, is actually in the link. :)

     

    Yes and yes.

    Greenhut,

     

    My issue sounds exactly like the one you described.  Around the time my syncing stopped working and I got that error message, I had 8,000 inadvertent playlists added via iTunes Match to all my devices.

     

    I manually deleted each one (yes, all 8,000) of these from my devices one at a time, but even after that I am still getting the error.  I suppose it is the possible that the playlists are still in iCloud and  it's causing my iTunes syncing to choke.  Is it possible that you can send me that script that worked for you?

     

    Windows Vista sp2, iPhone 4, iTunes 10.5.3.3

     

    Thanks,

    Booldude,

     

    The script is used to delete the playlists from itunes. There is one available for WIndows and Mac. If you already deleted all playlists from itunes, I have found that ittakes some time, but eventually syncs the deletes to other devices. Also, once rid of the playlists in itunes, you have no need for the script. If after all playlists are gone, you still cant sync, do a full iOS software restore of your iphone and I think you'll be ok.

     

    Good luck. I still have not had one sync problem once cleaning up the many thousands of duplicate playlists.

    Hey Jeff,

     

    Thanks for your quick response.  It kind of figures about the script.  After I posted that, I realized that I have probably already done what the script would have anyway.  My method was the old fashoned way of putting a few coins over the delete key to weigh it down and just letting it go. 

     

    Anyway, this is reassuring that the restore will probably work.  I've noticed after reading this board that about half the people have had problems restoring it, but with the other half it seems to have worked.  I am pretty much down to that last option of restoring, as I haven't tried to do it yet (for obvious reasons).  Also, I have both an iPad 2 and iPhone 4 where the sync wasn't working, so I was thinking a restore would be counted out since it is unlikely there is a problem with both devices.  But I understand now, that it is probably because of the iTunes Match thing that happened to us that a restore is probably necessary.

     

    It is great to hear that you have not had any sync problems after cleaning up the playlists .  Hopefully the same will happen for me.

     

    All the Best,

    Dan,

     

    Have all the playlists disappeared from the iphone and ipad? This took a while for me. May have gone faster by leaving the music app in the foreground. If they have disappeared, and you still cant sync, I would do the restore. If they havent disappeared, you may want to give them a chance.

     

    Also, be sure you leave itunes running for a little while after you are done deleting as all the deletes need to sync to iCloud. If you exitted itunes soon after all the deletes completed, and havent let it run for a while since, this could be why the playlists remain on the device.

     

    Good luck!

    Hey Jeff,

     

    All the playlists have dissappeared from my devices.  I had turned off iTunes Match on all my devices, manually deleted alk the playlists from iTunes on my computer, turned iTunes match on from the computer, then turned on iTunes match on my devices and it seemed to get rid of everything.

     

    I'll go for a complete restore on my iPad back to factory settings.  Do you recommend doing the same to the iPhone simultaneously as I'm doing this?  The risk I run would be losing movies and synced over photo albums.  Everything else would be moved over from iCloud.

     

    Thanks,

    Dan,

     

    It's good that all the playlists are gone. I would restore the devices one at a time. Assuming it works on the first, then do the second. I have never used the restore all settings as I am in the developer program and do a shift restore in itunes, and chose the appropriate ipsw file. Hopefully the restore all settings will do the trick. If not, I'll bet you can download the appropriate ipsw online somewhere for your specific devices.

     

    Good luck!

     

    jeff
