I've been dealing with this all evening.
Everytime I plug my phone in, the sync gets to step 6 and then that error as mentioned above pops up.
My system: Win7x64 My device: iPhone5
This problem only started today.
I've scoured the internet and have tried all these solutions with no progress:
1. Deleted old backups
2. Deleted the Lockdown folder
3. Reinstalled iTunes
4. Changed the time zone
5. Running as Administrator
To be quite honest I can't even remember everything I've tried and I am not just incredibly frustrated.
Could anyone lend a hand? I honestly Don't know what the issue could be. I also tried deleting apps from the phone, removing all my podcasts, pictures, etc.
Still that flippin' error message comes up.
Anything. Before I go crazy and reformat my computer.
Ok. I literally went through all of those steps, and then nothing on there worked.
I just fixed it.
Here's how I did it.
I went into the settings of the phone, erased EVERYTHING.
Plugged the phone back in, synced with nothing on it. Backed up, Worked.
Went to my old but latest backup from my iPhone4 before I bumped up to the 5.
I then restored from that backup, BUT. Didn't sync any of the apps, podcasts, or music.
Then by a process of elimination, I went one group at a time.
First I synced all my apps. Once all of them loaded, I hit the backup button. Worked fine.
Second, I synced all my podcasts. After, hit backup. Worked fine.
And last. My music. Synced all of it. Backup could not finish!
So I went through and tried to remember what was the last thing I added on there that could have added on there that could prevent it from working.
Oh. The first 3 Games of Thrones books you ripped from the library?
Once I deleted those. Synced fine.
I don't know exactly how the **** that was the thing that fixed it, but it did. I have the 32g model, and had around 12g of space free.
But it's fixed. So maybe a heads up to the people who might be experiencing the same problem. Try that out. Sync your categories one at a time, backup, and eliminate each one at a time.
I'd love to know if this helped anyone else.
