iTunes 10.5 hangs during iPhone 4 sync

Just installed iTunes 10.5 and attempted to sync iPhone 4/4.3.5 several times. The process hangs while "Backing up" with the status bar right under the t in (Step 1 of 5). I've swiped the phone to cancel, which leaves iTunes continuing on as if the phone were still syncing. I used Task Manager to quit iTunes on Win Vista, restarted iTunes and attempted to sync again. Hangs in the same place. So, I restarted the computer, restarted iTunes and it's still hanging during Backing up... I am so frustrated! Help!!!

iPhone 4, iOS 4.3.3

Thanks so much! After months of trying and researching on why my Iphone4 kept getting caught in the backup process while trying to sync and/or update to 5.0 software, I found this website. I did a few things that was suggested on hereand other apple forums and it finally worked! I went to C:\Users\user\AppData\Roaming\Apple Computer\MobileSync\Backup and deleted the backup. Note that the small user word will be your computer name. I then did the startup, accessories, right click on command prompt, run as administrator, and typed netsh winsock reset. Then I restarted my computer. When I started it up, I got this error message from Bsecure Internet Protection. It said some components of your internet protection have been removed using unauthorized tools. Recovery operation is complete. Please close all other open programs and restart your computer. I believe the netsh winsock reset caused this. I did NOT do this! I just opened Itunes and continued like normal.Turned on Itunes and then plugged my Iphone into the usb port. Itunes recognized it and started syncing and backing up with no problems. Thanks again. J I am so happy that my Itunes backed up, synced, and updated. Thanks for all your help!!!!!!

I cannot seem to run my vista PC as administrator.

I also tried the netsh wiinsock reset and got "requires elevation".

I tried the c:\windows\system32\cmd.exe

This is in the Command Prompt Box right ???

Here is what I get:

c:\windows\system32>

it won't allow me to backspace the arrow out so I could type "\cmd.exe".

I tried pasting the whole thing and hit enter, it just repeats on the next line and.....nothing. Nothing to right click on....


I have tried pretty much everything.

I have created a new administrator account, been all over the Advanced Security Settings Properties Page to take ownership, etc

I ran MSINFO32 and found 3 LSP's all by bytemobile which I believe is there from AT&T for my Laptop Connect Card.

I tried to uninstall the bytemobile software and the error said that I do not have permission. This was after I made darn sure that I was logged in as administrator.

By the way, I am gettting "Backing up" hang time and a "white iTunes store front".


Please help, I have pulled out all of my hair....see, no hair >>>> 🙂.

Thanks VickieS_AR 🙂 😀 😁


You are a f...ing genius !!!!!


I went into control panel, user accounts, turned off the user account thing.

Opened the command box, [it now said "administrator" at the top of the box] typed "netsh winsock reset".

Restarted my pc............opened iTunes...........and ............I now have a store front !!!!! YAY !!!!!!!


I have spent days......and nights..... trying everything to fix this....what a simple solution you had.


By the way......apple support spent 2 hours with me on the phone trying to get my pc to run as administrator so I could fix iTunes. He was very nice and patient, but his solution was for me to take my pc to the geek squad.


I took it to the message boards......thanks tons !!!!!! I am soooooooooo happy !!!!!!!! 😝


Now I can LOVE my iPhone 4S .😍


HAPPY NEW YEAR !!!!!!

I came across this thread after researching why Itunes would hand when attempting to sync. I did the litte netsh winsock reset trick, and was finally able to get Itunes to sync. However, when attempting to update to 5.0.1 from 4.3.3, it hung when "attempting to connect to iPhone actication server". I couldn't shut down iTunes at all, so I had to reboot.


After reboot, i get the normal Win 7 login screen but now when I login I'm greeted with a black screen and a mouse arrow, and hard drive activity. That's it... i've left it thinking it's resetting itself or something, but nothing. It never comes back. I can boot in safe mode, but that's about it.


When I try to log into a different admin account, I can get past the blank screen, but the desktop never loads. Seems that svchost.exe is hung up and tying up 99% CPU utlization. When I stop the service, it loads the desktop, but the system is unstable. I try switching back to my normal user account (which happens to also be an admin), and I get the black screen.

Does anyone know what is going on? It all started with this resetting of the winsock trick! All this just to try and sync and get my iphone updated... i'm really getting annoyed!


Anyone, please help!

This problem is quite common, but I have not been able to figure out what causes it. My best bet is that it's a USB issue, and I have found a workaround that makes synchronising possible when all else fails. For the record, I have tried all of the potential solutions on these forums without lasting success. Here's what worked for me.


(Windows 7 32bit, iPhone 4S, iTunes 10.6.1.7)


First of all, make sure you have a good wi-fi signal in the region of the PC you are syncing with. Then -


1) Start iTunes.

2) Connect phone via USB.

3) Left click on phone in iTunes.

4) On the Summary page check "Sync with this phone over Wi Fi"

5) On the phone go to Settings>General>iTunes wi-fi sync

6) Tap on Sync now.


The phone should sync via wi-fi, even though it is connected via USB. It didn't seem any slower to me than syncing via the cable, and more importantly it worked, and the backup went smoothly. I've tried it several times now with no problems.


Also, if you have a lot of apps you need to synchronise or you are re-arranging the app windows using iTunes you can sync in the normal way from the PC if you do it immediately after the wi-fi sync, because iTunes does not run the backup again. It probably won't run two backups within a few minutes of one another.


It's all a bit of a fiddle, and Apple/MS needs to get a fix for it, but if this method works for you at least you have a good backup should you flush your phone down the toilet!


Good luck!

I'm having the same problem but i have a macbook, the white ones that are discontinued. My ipod was sync on another computer, the macbook pro, but since it crashed, i decided to re-download all the songs on a different itunes. When i attached my iPod i accidentaly clicked the wrong button and whne i did the software update i checked my iPod and i saw that all my purchased apps and purchased songs disappeared. I re-downloaded the bought apps for free with no problem, but when i try to re-download the purchased songs (10) i clicked on the song and it said you already purchased this song, do you wanna purchase again? and the two choices were, purchase again, and Go back. PLEASE HELP! what should i do! i need help ASAP
