Error -42110. And backup of my iPhone

When I open the iTunes appear the unknow error -42110. And i cant do the backup of my iPhone. What I need to do to fix it?

Removing the SC Info folder as per the "Error 3001," "-42110," or "5103" section in the Specific Conditions and Alert Messages: (Mac OS X / Windows) section of the following document seems to help most folks reporting the iTunes launch 42110s:

An error occurred while backup up this iPhone (-5000)

I have an iPhone 4.
I backed it up using iTunes.
I then had to installed the latest iTunes (10.5?).
I backed it up using iTunes again.
I began the IOS 5 upgrade but I get the following error:
"An error occurred while backing up this iPhone (-5000).
Would you like to continue to update this iPhone?
Continuing will result in the loss of all contents of this iPhone
<Continue> <Cancel>"
Will my prior backups work? Is there a fix for this?
Thanks,

Forgot to mention that I'm on WinXP.
Anyway, another post pointed out that disabling the firewall/antivrius does the trick and it worked!

HT1926 How do I authorize a windows 8/64 but I/explorer computer?The Apple website is way out of date and the support led to an unknown error -42110 and the advice was wrong and inoperable from the support man Gulab

I have bought a New Computer as my Old one did it's HDD. I now have windows 8/64 bit I/E 10 and am trying to Authorise my New Computer. I have downloaded the latest version and I got an ""unknown error -42110 "" .I went to te apple website and that says how to deactivate a SC folder or something in windows 7 or windows vista.
It also says to go to ""store|"" > Authorise Computer"" and I can't get anything,so I contacted Apple support and I got some person called Gulab who sent me links to the same obsolete apple website which says exactly what I have said above.
I open iTunes and it lets me login with my apple id and says that I have $78.00 in credit and to be honest I can't understand the updated version/s let alone find how to ""Authorise "" my new computer.Gulab said to delete te sc Folder but the website (Apple) says this ios for windows 7 and windows vista.
Running around in circles. Apple website needs to be drastically updated instead of updating iTunes .
Completely confused and so is the support staff....lololooolololol

(1) There's a couple of ways to get through to the authorisation controls in the 11.0.x versions.
The control is still in the Store menu, but first (if you're using iTunes versions 11.0.x) you might need to bring up the menu bar to see the Store menu.
If you're using 11.0.x, click on the wee boxy icon up in the top-left corner of your iTunes to see the "Show Menu Bar" control, as per the following screenshot:
Then you'll find the control in the Store menu:
Alternatively, if you don't want to bring up the menu bar, it's still possible to get into the authorise controls via nested menus accessible from the wee boxy icon. Here's a screenshot of where to find them:

Hi, I have problem with updating and backup my iphone to imac. If you can help me about my problem that will be great.

Hello jennywijaya,
I would be concerned too if I was not able to backup my iPhone. I recommend the following article for troubleshooting backup issues with iTunes:
iOS: Troubleshooting backup issues in iTunes
http://support.apple.com/kb/TS2529
If you are still unable to update after creating the backup, I recommend the following article:
iOS: Unable to update or restore

Thank you for using Apple Support Communities.
Best,

Lost Contact and Backup Information on iPhone and Mac Computer

I recently had a serious computer crash (not sure how, because Mac has ALWAYS performed exceptionally), but I had to totally re-install the OS system on my computer, of course losing ALL the old data... HOWEVER, I was able to save or back up all my old data to an external hard drive, but now I can not find the iPhone data anywhere on my external drive. Is the iPhone data saved in a "hidden file"somewhere??? And even if I can find the file, how can I extract the data, and get it back on my iPhone??? And to complicate this dilemma even more, I used my Macbook Pro 17" notebook computer to service or activate/update both MY iPhone as well as my wifes iPhone. It is my wife's data that is missing or lost.. Please help me... Lost without contacts...
Thanks,
Lester

Yes, I "initially used "Time Machine", however, I believe one of the reasons my computer crashed in the first place was because I got a virus or worm, and after several days of trying to restore my computer using the Time Machine option, it would never completely restore properly.. I realize this might sound crazy, but I believe whatever effected my hard drive, may have effected time machine also.. I can't be sure... But to answer your question specifically, I went into my time machine, and I transferred the complete "user" folder to another clean external hard drive... And the funny thing is, since you told me where to look for the mobileSync files, I can find them on the new external drive, but nowhere to be found on the time machine.. I hope that answers a few question...
Please don't give up on me yet... I am desperately trying.. *humble smile*
Thanks
Lester

Transferring and backuping music from iPhone to PC

My iPhone have a lot of songs,have taken up so much of my memory,so I want to move these music from iPhone to computer,but it is difficult for me to solve it,this my question,ask for helps!believe you can help me to solve it!

If you want to transfer music from iPhone to computer with iTunes, you may come up with some difficulties. On one hand, as a one-way transfer tool, iTunes doesn’t allow users to copy music from iPhone to computer or iTunes for protecting the copyright of the music; on the other hand, when syncing with iTunes, this software will only maintain the purchased items in your iPhone and try to erase the files that aren’t got from iTunes. Therefore, it will be hard for you to transfer music from iPhone to computer with iTunes.
But if you insist on transferring music from iPhone to computer, you will need a third-party transfer tool to help you. Being regarded as the best iTunes alternative, Coolmuster iPhone iPad iPod to computer transfer provides great help in the file transfers of iPhone, iPad and iPod. With Leawo iTransfer, you are able to transfer music from iPhone to computer within seconds.

Tried updating iphone 4 to ios 5.01 an error occured and now it shows to connect to itunes, Tried updating iphone 4 to ios 5.01 an error occured and now it shows to connect to itunes

so it hasnt been updated for a long time (the update before ios5) and i wasfinally going to update it. Through the process an error occured and I unplugged my iphone 4 from my computer. Now it just shows an apple logo and it shows the itunes icon and the end of a charging cable (the usb side) basically it's telling me to connect to itunes and so I did and nothing itunes does not pick up a sign that my phone is plugged in. Please help! I will greatly appreciate any information on how to fix this problem!

You could reset your iPhone by holding the on/off and home buttons together for 6 or 7 seconds till the Apple logo appears.

Why does it take hours to sync and backup a 12GB data?

Does anyone know why it takes hours and hours to just sync and backup my 16GB iPhone 3GS before it installs the iOS5? This is getting rediculous! Why do Apple force us to use iTunes?

Shouldn't take that long although waiting a long time in between syncs can create longer backup times... ie more data, apps, etc... to back up etc... Make sure both iPad and iTunes are most current versions. Make sure you are using the iPad sync cord that came with the device and not another from a iPhone or iPod. Cables can screw up the deal.
Start there first and let us know how it goes.

Try runing iTunes in admin mode. That fixed the issue for me. You can either right click on the shortcut on your desktop and choose to run as an admin each time you launch it or go to the advanced tab under security on the program itself and click the run as admin every time.

Salve a tutti, sto cercando da stamattina di effettuare il Backup del mio IPhone da 32 gigabyte. Quando avvio la sincronizzazione e il Backup mi esce scritto '' iTunes non ha potuto eseguire il backup di Iphone perche si è verificato un errore. Ho provato su un altro iphone (4) e tutto funziona correttamente. Non posso ripristinare il dispositivo perchè ho troppi dati importanti sopra. Vi prego aiutatemi.

Ok I tried to delete the backup by using your location via preferences, but I did not find any file, maybe because I've already deleted following the path to the disk. I repeat that I have 2 devices and the problem only occurs on one

If iTunes is otherwise working properly start with TS1538: iOS: Device not recognized in iTunes for Windows, in particular section 5, otherwise move on to Troubleshooting issues with iTunes for Windows updates.
