Cannot sync iphone. an unkown error has occured (-50)

I cannot sync my iphone 4. I keep getting this error: cannot sync iphone. an unkown error has occured (-50)
Tried a hard restart on the phone and repair/reinstall of itunes. I can backup the iphone, does anyone know how to solve this problem?

Error 13, 14, 35 and 50 (or -50)
These errors are typically resolved by performing one or more of the steps listed below:
Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting.
Put a USB 2.0 hub between the device and the computer.
Try a different USB 30-pin dock-connector cable.
Eliminate third-party security software conflicts.
There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.
Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.
Try to restore from another known-good computer and network.

"The iPod cannot be synced. An unknown error has occured (-48)"

*The iPod "Ash" cannot be synced. An unknown error has occured (-48)*
Has anyone else had this pop up to themselves or does anyone know how to get anywhere on getting it fixed.
When I try to upload my iPod onto my iTunes, once it gets recognized that pops up and it won't progress anymore. I've tried the Five R's, which haven't helped me and it has also screwed up my album covers, but that is the least of my worries.
If anyone knows how to help me out, that would be very appreciated.

WHat kind of iPod? Seen this?

The iPod cannot be synced. An unknown error has occured (-50). PHOTOS ONLY.

Hi there. I have searched with no success, to solve this problem: I have a 1st gen. Touch and only recently, I get the following message when attempting to sync with my mac: The iPod "customer's pod" cannot be synced. An unknown error has occurred (-50).
This only happens when I have selected photos to be synced. This never happened before. If I de-select the photos, there are no problems.
I am running iTunes 8.1 and version 2.2.1 iPod software. I have done a reboot, restarted and so far nothing has worked. I have searched this forum and have found assistance for people running a PC but so far, can't find anything that has worked for this situation. If this has been answered previously, my apologies. I appreciate anyone who can help out and/or point me in the right direction.

Thank you! I deleted the ipod photo cache and it worked. (apologies for not writing sooner... my ibook crashed and I just got a new mac and synced up).
Thanks so much - very appreciated.

I keep getting a message when I try to sync music onto my ipod that says "iPod cannot be synced. An unknown error has occured (13019)"

I've never ever had this problem before; it's only been the last few days. Every time I try to take music from my library and put it on my iPod, the message always comes up that says, "iPod cannot be synced. An unknown error has occured (13019). What should I do? This has never happened before!

Did you already try to restore your device? Restoring iPod to factory settings
Other solutions for this errror are mentioned here: iTunes: Error 13019 during sync

"cannot be synced. An unknown error has occured. (13019)"

When I connect my iPod touch to iTunes there are several songs and videos that are apparently on my iPod (it says they're on the device). Then when I go on my iPod, they aren't there. I tried syncing but everytime I try to do so it says "Cannot be synced. An unknown error has occured. (13019)" I've tried restarting my computer, restarting the iPod, using a different computer, everything. Oh, and I put 96 new songs onto the iPod via iTunes successfully last night. Help!?

Hi breakingbenjamin27,
Thanks for visiting Apple Support Communities.
If you see an "error 13019" when trying to sync content to your iPod touch, be sure to try these steps:
The error will most commonly occur while syncing music. This issue can be resolved by following these steps:
Select the device name in iTunes under Devices.
Click the Music tab and under the Sync music option, choose Selected playlists.
Deselect the Voice Memos playlist.
Click Apply and then click Sync.
If the above steps do not resolve the issue, check the device and the iTunes library for duplicate voice memos. If you find any duplicate voice memos, delete the duplicates and then sync.If those steps do not resolve the issue, then follow these steps:
Select the device name in iTunes under Devices.
Click the Music tab and deselect the Sync Music option.
Click Apply and then click Sync.
After the sync is complete, reselect the Sync Music option.
Click Apply and then click Sync.

ITunes Library cannot be saved. Unknown Error has Occurred (-54)

I have been having the following message appear in iTunes:
iTunes Library cannot be saved. Unknown Error has Occurred (-54)
I created a new library which seemed to solve the problem.... until I plugged in my iPod Classic or tried to Sync my iPhone. When this happened this warning message would come every 10 seconds or so making it a nightmare to do anything as the dock icon would bounce or iTunes would pop up. Can anyone suggest what might have caused this problem and how to resolve it.
Thanks
Matt

Hi pholewinski!
I have a couple of articles for you here that I believe will help you with this issue. The first is an article on advanced troubleshooting, and it can be found here:
iTunes: Advanced iTunes Store troubleshooting
http://support.apple.com/kb/ts3297
If following that article's steps doesn't take care of the issue, you can try the things listed in this article, which is about permissions issues in iTunes:

While making a backup copy in Itunes of my Iphone I receive the following error message: While making a backup copy of this iPhone (-35) an error has occurred. Do you want to continue with altering this Iphone? When you continue al the material on this Iphone will be lost.
I reinstalled iTunes but that dit not help. After synching iTunes with my iPhone it also asks to authorize my pc and when i Click on ok, it says it is already authorized.
Please can somebody help me, so I can make backup.
Greetz,
Derk

It's likely that your backup is corrupt. Try deleting the backup, then right click on the name of the phone in iTunes and choose "back up". To delete go to iTunes Preferences, Devices tab. Highlight and delete the most recent backup. Note that sometimes deleting this way leaves some garbage around that can still interfere with a new backup, so you should verify that the backup folder is empty.
from: http://support.apple.com/kb/HT4946
The folder where your backup data are stored varies depending on the computer's operating system. Make sure the backup folder is included in your periodic data-backup routine.
iTunes places the backup files in the following places:
Mac: ~/Library/Application Support/MobileSync/Backup/
Windows XP: \Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\
Note: To quickly access the Application Data folder, click Start, and choose Run. Type %appdata% and click OK.
Windows Vista and Windows 7: \Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\
Note: To quickly access the AppData folder, click Start. In the search bar, type %appdata% and press the Return key.

Ipod cannot be updated, an unknown error has occurred. (-48)

I'm at the end of my tether right now. I updated iTunes to the newest version, then updated my iPod. Now I'm getting the error message "Ipod cannot be updated, an unknown error has occurred. (-48)". I've searched the site and other forums and I can't find anyone with that same message who can help me. I've tried installing an older version of iTunes but I can't use it because my iPod has been updated to work with the newest one. I've uninstalled and reinstalled iTunes, nothing helped.
So my questions are:
1) Any way I can uninstall the update I did for my iPod? That is, so it is compatible with older versions again.
2) What could be causing this message?
3) Is there an e-mail address for apple, who seem wholly uninterested in what happens with their product once the £235 has been paid for it?
Any help is appreciated.

Interesting, that error code doesn't seem to appear on the iPod support pages. Since it's saying "The iPod cannot be updated" it sounds like it's indicating there's a problem with the iPod... although with "unknown error" it's hard to say for sure. My recommendation would be that you try restoring your iPod, and then giving it another go. If you're uncertain about the restore process, take a look at this article, it should answer your questions.
http://docs.info.apple.com/article.html?artnum=60983
Once you restore it, try updating it again in iTunes. If you have any more problems or questions, feel free to reply, and I'll see what I can do to help.
Best wishes!

The ipod "name" cannot be updated, an unknown error has occurred (-48)

a few nights ago while i was updating songs to my ipod video, this thing appeared on the screen in a quick flash and i wasnt able to read what it said. then my computer blinked and resetted, causing my ipod to unplug without ejecting properly. so i pulled out the plug from the butt of the ipod only to find out that when i opened it, all my songs were gone. a good 3000 i think. i think i also pressed menu and play at the same time after that.
the ipod "name" cannot be updated, an unknown error has occurred (-48)
this is what keeps appearing on my i-tunes everytime i try to transfer songs to my ipod vid. the weird thing is that when i drag and drop songs from i-tunes to the ipod icon, it says its updating. but when its all done, not a single song appears on my ipod. and it also said something like "cannot be restored" and "ipod service error" on the ipod updater. i've tried on both computer and laptop and am experiencing the same problem. as of now, my ipod is working but it's just all empty. could anyone help? im so frustrated coz this is the second ipod i've purchased since the last one that broke down. thanks.

k i tried that but i couldnt find cupertino usa on my ipod. i did: date and time - set time zone - then a list of places come out with (DST) beside each of em. i chose bangkok (dst). tried to plug it again on i-tunes and the same darn thing appears. that dreaded -48 error. ill check out the rest of those links you guys posted anyway. thanks again for tryin to help.

The iTunes Library cannot be saved an unknown error has occurred (-48)

Every few minutes, I get an error message from iTunes that says:
"The iTunes Library cannot be saved an unknown error has occurred (-48)"
Quitting and restarting iTunes doesn't seem to make the error go away. All of my music and movies seem to play just fine - not sure why the error keeps popping up - any clues?
- iTunes library is located in it's normal spot (~/user/music/iTunes/)
- OS 10.8.2
- iTunes 10
- iMac 27" early 2010

Thanks again for the gracious response UV.
You've pointed out a problem...there are a lot of WAV files that I have like unreleased live shows of bands like the Beatles, Neil Young, Miles Davis etc that I've gotten off Bittorrent trading. When I look at the "get info" part of the song in iTunes the details that I've hand entered (dates, venue, song, musicians,etc) does show up.
But when I go back to the actual file itself, many are simply tagged something like "track 1" and the only way I currently keep track of all this is how I organize my library ( Musician or Band folder \ Album folder \ indivual tracks). There are literally thousounds of songs that I've entered data for on these WAV files.
Besides getting my current error problem fixed, has anyone who trades live shows come up with an easier way to organize their music. I understand that I may be in the minority with all my WAV files and that many users simply upload CDS, or mostly buy tracks online which is easier to simply grab the data back if they need from some database. I feel like I'm missing out on something big. Maybe I just need a different program for my particular application (archiving & playing music). ANy ideas from other bittorrent traders of unreleased material?
I am learning more and more about how this all works by the minute, and have taken your advice UV about copying all my current library info and putting it somewhere safe. Hopefully this means everything I've entered up until a few days ago will be fine. Still, I have plenty music waiting for me to hear in FLAC files that need to be decoded into WAV files; but I want to wait to do this until I can be certain all my hard work entering data won't go to waste and my error problem has been fixed.
thanks for all insights - Sonny
