Iphone 3g sync error

I have been trying to sync my iphone 3 for months. The only way I get it to sync is to restore it to the original settings. Everything goes fine till I get to step 4 of 4 and I get the message "Itunes could not back up the iphone "iphone" because an error has occurred". I have tried everything and nothing seems to work. Itunes has the most current version and my phone is up to date. Can anyone please help me?

I found the culprit. I was logged in to my account, with my wife's account active in the background. Her account had iTunes open. When I logged out of my own account (having closed iTunes) and went back to hers, her iteration of iTunes popped up a bunch of notices about trying to sync my iPhone.
Thus, I quit iTunes under her account (and made sure no other accounts were active), logged back in to mine, opened iTunes, and am now successfully syncing. Problem solved.

IPhone not syncing - error 1139

Since recently I receive the following message from iTunes when I'm connecting my iPhone to sync with it. Does anyone know what I can do about it?
The iPhone "name" cannot be synced. An unknown error occurred (1139).

I am getting the same error. In iTunes, when I highlight my iPhone and click on the "photos" tab, my phone is trying to sync all photos and albums. The choice of "select albums" is there but is not available to select as it had been in the past.
So anyone know why we can't select that option anymore?

Iphone 5 syncing error, code 1156?

I am getting an error message that says cannot sync, an unknown error occured, (1156). I've already restored the iphone 5 twice. its brand new.
anyone have a clue what this code means?

Reboot your computer. If it doesn't help, try this:
Sign out of iTunes Store
Disconnect iPhone and switch off ‘sync over wifi’
Close iTunes
Shutdown and cold re-start computer
Start iTunes
Dock iPhone and allow sync to take as long as needed (10 mins+ for me)
Force new sync and watch steps flow through
Sign in to iTunes Store

IPhone 4 Syncing Error- Too Many Computers

I get an error message that says my iPhone has been cynced to 5 computers and it won't sync to my new MacBook Pro. Is there any way to Unsync it from computers I no longer have access to? We're talking about computers from three years ago, before I even had the iPhone 4 (I'm guessing; the error message doesn't give me any more info than that)!

You need to do a factory reset (erase all content and settings), set up as new phone, then input your icloud info to restore some data lost (contact ect..)
1. Set icloud to sync your important information
2. Remove any / all data from the device (backup will not work)
***PERFORMING A BACKUP VIA ICLOUD OR ITUNES WILL NOT RESOLVE THIS ISSUE - IF YOU RESTORE FROM BACKUP THIS FIX WILL NOT WORK! MUST SET UP AS NEW PHONE!
3.Settings>General>Reset>Erase All Content and Settings
4.Setup the iPhone (You Must Set Up As New iPhone)
5.Go to app store - no error
6.Sign into icloud and itunes account (Do Not Restore From iCloud Backup)
7.Go to app store - still no error
Hope this helps.

Iphone Photo Sync errors

I get an error every time I attempt to sync photo's to the iphone... What gives?

What firewall is installed on the PC? You can try to disable it or set it up again.
You may also want to check with Dell, to make sure you have the latest firmware updates for the PC.

IPhone photo sync error

Hello,
I would like to get the photos from my PC to my iPhone. Everytime I try to sync I get an error message that says "the iPhone xxxx iPhone cannot be synced. The required file cannot be found". Then I click OK, but there is no description of what file cannot be found. Not a very intuitive message. Help! Any suggestions to resolve this issue? Thanks.

HT1386 iPhone 4S and iPhone 3G Syncing Error with iTunes

I am trying to back up my iPhone 3G so that I can import the new information to my iPhone4S. Every time I try to plug it into my new computer it tells me I need iTunes 64-bit. When I uninstall and reinstall iTunes 64-bit it still doesn't work.
I am trying to use both my new and old computer and am still not able to seem to get it to work. When I plug the iPhone 3G into the old computer I also get an error.
Argh. I also just tried syncing my new iPhone and it reads the same error message about re-installing iTunes 64 bit. I have re-installed at least 5 times already.
Please let me know any advice or suggestions that you may have.
Thanks!

Hi Macafreak,
I'd like to see if unchecking the "Sync Music" box, applying the changes, and then re-checking the box resolves this issue:

New Iphone OS5 Sync Error With Outlook

Hello everyone,
Below are the errors that I keep recieving when I try to sync my Iphone, with my Outlook 2010. I highlight the Outlook abd click next because, it is the most up to date. I guess my next question is, what can I do to fix it?

Hi,
This way I found the corrupt reoccuring entry:
synch with outlook ran to error - found a post saying that deleting all calendar entries in phone may help
calendar on phone can just delete entries in past - so changed clock to future time and wanted to delete all entries
'system error' or so came when I tried delete all calendar entries
start playing with changing phone clock to various future dates and trying to delete calendar
deleting was only possible when clock on phone was anytime before the end of reoccurance of wrong calendar entry - when all instances of reoccuring entry were 'in past' for the phone, than deletion crashed with error
Don't know if there was attachment - cannot open it, but I do not think so.
Following your suggestion opened backup file with Noki, but most entries are not backed up - out of 328 identified entires only 30 are appearing in Noki list. Could happen that corrupt entry blocks the proper backup as well.
Thanks a lot.

An easier and quicker way.
This error is associated with your iPhoto library.
Navigate to <username>/Pictures/iPhoto Library
Right-click on iPhoto Library and show package contents.
Remove the folder iPod Photo cache (delete it, move it to Trash or whatever you want - just remove it from the iPhoto Library!)
Sync your iPhone. The photos will reverify and, bin go, you're done.
I had 3833 images and it took less than 10 minutes.
All fixed.

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.

IPhone and iPad error when syncing with itunes

iTunes cannot sync my iPhone 4 or iPad air, iPhone produces unknown error (-50), and iPad produces unknown error (-54), cannot sync. This problem started in the past seven days. Neither device is Jailbroken, so I know that's not a cause, any help?

I was having this problem and there isn't a lot out there about it. But it seems to have gone away with iOS 7.1, which is nice.

Just downloaded iTunes to new dell laptop, tried syncing my iPhone get an error message: "this iPhone cannot be used because the Apple Mobile Device service is not started". What is the issue, had this phone over a year??

I had this problem before. I like to disable extra services to speed up my computer and I disabled the Apple Mobile Device service and had to re-enable this.
You can do that by going Control Panel>Administrative Tools>Services. Once you have gone to the services window, look for Apple Mobile Device and right-click. Select "Properties". There should be some information about the service as well as the label "Startup Type" with a drop-down menu beside it. If it says "disabled", that is your problem; Change the selection to anything except disabled (Automatic is easier and ensures that you can sync as soon as itunes opens).
If this doesn't work, I would look into your anti-virus' settings. Good Luck!

My problem - when syncing and error messages comes up: iTunes could not sync calendars to the iPhone because an error occurred while margin data." I've tried turning the phone off and back on, & tried both USB ports but get the same thing. What can I do next since it doesn't give me even one clue as to what the error would be?

Before I started to resync calendars one by one as suggested in the troubleshooting article, I remembered something that came up in a sync when I first attempted : a 'which one do you want to keep' message about a repeating calendar event, which came up with three options, one from Calendar, and two from iCal on the phone. I deleted that event, then went through the calendar resync one by one, and all seems OK now.
In Music there is a way to find 'ghost' items that show up as grayed-out on the menus, so that you can try to reassociate or delete them. It would be nice to have a similar way to work with Calendar!
Thanks for pointing me to the right article.

I connected my iPad and iPhone to sync just now and got the message, "The iTunes Library cannot be saved. An unknown error occurred (-54)." What does this mean? I clicked "OK" and the sync appears to have worked properly. Thanks - dalebird
