IPod Touch won't sync to iTunes. Keeps popping up with unknown error.

Just recently this has started happening. I try to sync my iPod to my iTunes, and it'll sync halfway and then an error message will pop up and say, "The .. ipod can't be synced. An unknown error occurred (13019)." My iTunes and my iPod are all up to date, and I've tried turning off my iPod and resetting my iTunes but I still get the error message. What gives? How can I fix this?

Try here...
iTunes: Error 13019 during sync

Sync continually fails with "Unknown error." Been happening recently (used to work). Anyone else having this problem?

Mac OS X 10.6.7, Firefox 4.0.1.
Sync Now from the menu likewise fails.
Attempting to get the sync quotas from the Preferences also comes back with a similar error.

To add a clarifying point in my case, which may or may not be universal for the others having this problem as well: it came within minutes of the update to 4.0.1, so it seems likely it has to do with the new version. OP said it used to work but started happening recently, so it could be the same cause as mine, given the recent release of the update, and OP's indication that 4.0.1 is also in use.

I have itunes set up to sync with my Ipod Touch and my Ipad. As of today, it keeps looking for an iPhone to sync with and give me an error message. I don't have an iPhone and don't know how to stop it from popping open with this error message.

I have Itunes set up to sync with my Ipod touch and Ipad. As of today, iTunes has started searching to sync with an iPhone, which I don't have and pops open with an error message stating it cannot locate the iPhone to sync. I have looked in devices and only the iPad and iPod Touch are listed. Any ideas on how to stop iTunes from searching for any iPhone it is never going to find? It is annoying to have it popping up all the time with the error message. Thanks in advance for any suggestions.

You should really read the manual.
"How do you restore from backup? "
Restore. When given the choice, choose to use backup.
"And how can I check to see if the pics and videos are on my computer somewhere first??"
They would only be where you put them. What program did you use to import them? Pics/vids taken with ipod are not part of the sync process at all. You should be importing them just as you would with any digital camera.
If you did not import them, then they are not on your computer.

Reset your iPad and see if that helps.
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.

Ipod touch won't sync music comes up with unknown error 13019

my son's ipod touch 2nd gen won't sync music with itunes library, comes up with unknown error 13019.
i tunes library is running version 5.0.1, ipod touch running 4.2.1 (highest upgrade available for this generation I have been told)

Have gone to support page and done what they suggested. I removed all the music without a problem but when resyncing it it failed again. I watched it load all the music on and then at the final stage of syncing it failed and came up with error 13019 again and now the ipod has NO music on it and I am in trouble!!!

3GS froze, then said Activation required, now fails to restore with unknown error (1)

My 3GS froze while using Navigon, then showing a pop-up saying "Activation required". When tapping the pop-up, an unusual white question box regarding location service shows up, after tapping "next" the process hangs. Connected to iTunes later, same procedure again, hangs again. When trying restore with iTunes, the whole load process looks ok, but at the end fails with "unknown error (1)", probably when trying to rstart the phone. I tried all variations (restore mode, DFU mode, hard reset) but no luck. The phone was recently officially unlocked (AT&T), could this be a factor? Or is this a harware problem? Any ideas aor hints welcome.
Thanks,
Manfred

Thanks for the pointer to the KB article. Error 1 is missing from the list provided by iTunes (more information), but I was afraid it means hardware. Will try on another computer, but I'm afraid the phone is sick.
Thanks,
Manfred

I went to another Apple store today and again brought up the issue of my iPod not syncing. As I mentioned before I've attempted to sync using two XP Pro computers with identical music files, different hardware but fully up to date XP Pro, including iTunes. Both failed. Identical music files on two iBooks running OSX (10.3.9) with up to date iTunes synced every time.
Add to this that I went to two different friends with very different music libraries and had problems on their machines as well (both XP machines, one home, one Pro)...neither person had problems with syncing their newer iPods.
At the store the guy did a restore of the iPod (something I've done many times) and he tested some 300 music files with no problem. He restored it again and gave it back to me.
I brought the iPod home and successfully synced 3853 music files with ABSOLUTELY NO PROBLEMS! I don't have any clue what was different when he did the restores, but it worked.
Of note, before anyone asks, everytime I've ever tried a sync on all of my computers or my friends computers, I've always triggered a restore to try to fix the iPod.

Im trying to install iTunes on my friend's Dell XPS, running windows vista ultimate (32-bit), but whenever I reach the end of the install, it pops up with an error telling me: "Service 'Apple Mobile Device' (Apple Mobile Device) could not be instal

Trying to install iTunes on my Laptop, running windows 7 (64-bit), but whenever I reach the end of the install, it pops up with an error telling me:
"Service 'Apple Mobile Device' (Apple Mobile Device) could not be installed. Verify that you have sufficient privileges to install system services"

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for performance issues or compatibility with third party software.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

Hi sailesh.chopra,

Skip the iCloud sign in for now.
Once you reach the home page, go to settings and sign out of FaceTime and Messages. This should also sign you out of iCloud.
Go to iCloud in settings and sign in with the correct Apple ID.
If that does not work
Skip the iCloud sign in
Go to Apple ID.apple.com and sign in
Change your Apple ID to the old one
Delete iCloud account on your device with the old Apple ID and the same password.
Go back to the website, change your Apple ID back to the current one. You will receive an email to verify the account. Verify first.
