ITunes freezes when syncing iPad 2 and iPhone 4. Error -20

I have the latest version of iTunes installed on windows xp. When attempting to sync my iPad 2 and iPhone 4, iTunes immediately freezes until I unplug the device. I have tried restoring my iPad, but I'm still experiencing the same issue.

ITunes freezes when syncing iPad to a new comp

I recently bought a new computer to replace my old one, and now my iPad 2 won't sync. iTunes just freezes, even though I "authorized" the new computer (which has a different name than my old one). What measures can I take to sync my iPad to the new computer? This is driving me a bit crazy, so any advice would be appreciated. Thank you. (In case it matters, I'm using the latest version of iTunes on Windows 8).

I've occasionally had my iTUnes freeze, both on my win 8 and my old vista computer. Every time you open iTunes, it reaches out to connect to the iTunes store. You may need to use the task mananger to shut it down or restart your computer if it's frozen at the moment. Then try opening iTunes, let it get up and going, then plug in your iPad. It's possible that it starting up, communicating iwth Apple and trying to communicate with your iPad all at the same time is too much for it and it freezes.
iTunes 11 can be very glitchy when it's in the mood to be. You almost have to baby it by letting it get going before you try to do something else.

Latest iTunes Hanging when connecting iPad 2 and iPhone 4

Hi,
I have an iMac running OSX. I have updated both mavericks and Itunes to the lastest updates. When using itunes it will start fine. Then when connecting either ipad or iphone, itunes then hangs with the spinning circle. I have left this for well over 2 hours now. The only way out is to quit itunes. I have tried the iTunes help but with no sucess as yet.
I have created a new user and the problem does diappear.,so its not an ipad/iphone or mac issue. I have tried removing my library and then connecting a device but iTunes does the same thing. I am guessing something within my Mac user profile is stopping it.
Please help, its driving me mad.
P.S I also have a mac book which is working fine.

ITunes could not sync ^0 to the iPhone Unknown Error(-19) during 2.1 update

iTunes could not sync ^0 to the iPhone Unknown Error (-19) during 2.1 update
Anybody getting this? On a Win XP iTunes 8/ iPhone 3G
Thanks for any help!

I got this message. After several hours of frustration...
I finally did a successful update by following various recommendations in this thread.
Maybe all or only a combination were necessary:
1) Deleted my backups. This DOES appear to be necessary, I noticed that the update was always failing when the update was going through the backup process. It was only after I deleted my backups that the update finally worked. To do this, in iTunes go to Edit > Preferences. Click on the Devices tab. Click on (select) the iPhone in the window. Click on the "Delete Backup" button.
2) Disable automatic syncing for the iPhone (don't know if this was necessary but it's one of the steps I took)
3) Make sure all your Apps are updated before trying the iPhone update. (Again I don't know if this was necessary but I did it). I updated my apps over wi-fi from the iPhone rather than via iTunes.
Important!!!!! After you run the update there will be no backup of your iPhone. You need to create a new one. To do this, right click (option-click) on your iPhone in the "Devices" list of iTunes. Select "Back Up" from the context menu.
Hope this helps!!!!

ITunes freezes when syncing with iPhone, but works fine with iPod?

It's a bit of a long story with my iPhone/iTunes problem. In late July, my iPhone stopped syncing properly. It's an iPhone 4. Basically, I tried to add more photo albums to sync onto my phone, something I have done before. It began syncing, then notified me that it couldn't sync 'x' amount of photos. It was a pop up on my phone screen. I tried deleting my cache in My Pictures, still errors. Then it seems like everything possible has just glitched when I sync as weeks went on. It wouldn't sync music. The songs would appear gray and failed to play. Sometimes it worked, sometimes it doesn't. Now, iTunes freezes when it reaches the end of the sync and I have to ctrl+alt+del to close iTunes as it stops working.
I took my iPhone to apple, and she ran diagnostics and couldn't figure out what was wrong with it. She told me she couldn't run diagnostics on my iTunes because it's a Windows laptop and she's "not trained to work with them". She said everything seemed fine with my iPhone and asked if it was possible if I have a virus. I've had no other problems with my laptop whatsoever and I have a decent virus protector that we pay for monthly.
I have tried restoring my phone twice, with a backup. I tried again WITHOUT a backup, and still, it freezes when it syncs, some songs are gray on my iPhone and won't play, and photos refuse to sync, period.
I then tried syncing my dad's iPod with my iTunes, and it worked. I also tried syncing my iPhone on my dad's laptop, and it worked. So something is clearly glitching between specifically my phone and my iTunes. I'm avoiding uninstalling iTunes at all costs because I don't want to lose play count information as the majority of my playlists are created this way. I thought iOs 7 or iTunes 11 (now 11.1) would fix it, but neither did.
Can anyone determine what the problem could be and how to fix it?

the same thing is happening with me. itunes will freeze and then it wont put songs on my ipod.
im starting to get upset since i just went out and bought a new ipod. thinking that was the problem.
PLEASE HELP!!!

Blue screen of death when syncing to iPod and iPhone.

I wish I could laugh. "Upgraded" to iTunes 8 and no longer can use my computer to sync to either my iPhone or my iPod. Thanks for the upgrade Apple. Now that I cannot update my portable music devices I have the extra time to stare at the new visualizer. Woooopie.
Apple is happy to point out how unfriendly Microsoft products are, but since I got this Vista box I have never seen the BSOD... Until tonight.
So, what to do? Wait for a "solution" to my upgrade, or try to remove 8 and reinstall 7? After reading about the changes to the iTunes library making a revert difficult, I am thinking I watch TV instead of listen to music. On the television... that is...
Paul

Replying to own thread because I wanted to share success. Turned power off on HP Laserjet. No reboot needed. Launched iTunes and performed sync with iPod and iPhone. Happy days. Even happier when Apple redoes driver so I can use iTunes without having to power off my printer.
An honest mistake... I would imagine it would be very difficult to find a beta tester that had that combo of hardware. Imagine... Vista and a HP Laserjet. Oh... I guess we are the beta testers...

Itunes crashes when syncing Ipad with mp4 movies in photo folder for keynotes

I'm trying to upload a small MP4 video onto my Ipad to use in Keynotes. I place the video in the photo folder and select sync, then tunes crashes.
I had created the video in Corel Video Studio pro 3 and created MP4 file. Copied to the IPAD and had it all working. I then made changes to the video and reconverted and now Itunes crashes when syncing.
Itunes 10.4.1.10 Ipad 4.3.5
Please help urgent

I had the same problem, and it turns out that the problem is having the same file into different folders. For example I had an MP4 in iTunes, and the same file in the photos folder that was being updated to the iPad. So I just removed one file and it syncs perfectly.

Itunes freezes when syncing ipod classic 160GB

I just downloaded the new itunes 1.6.1 and everytime i try to sync my ipod classic it gets about a tenth of the way through syncing the songs then completely freezes, i have to exit using task manager and it leaves me with no songs on my ipod. I've tried resetting my ipod and such but none of it has worked, i've spent the last 3 hours looking for a solution but there is nothing out there, please help!!!

Try connecting the iPod Classic to a different USB port set (like the ones on the back of your PC), and make sure you're connecting it directly to the PC, not through a USB hub (like the ones built into keyboards or monitors). If iTunes still freezes, run Windows Update and make sure you update all of the hardware drivers for your PC, especially ones marked "Chipset" or "USB Controller". Frequently, when iTunes freezes mid-sync with a USB device, it's because of an error with your USB controller or that set of ports. The steps above should get you syncing properly again.
If that doesn't work, try connecting your iPod Classic to another PC and sync some songs to it. If iTunes freezes there as well, it may be a problem with your iPod Classic (unlikely, but possible), and would warrant a Genius Bar appointment.
Hope this helps.

ITunes could not sync ^0 to the iPhone Unknown Error(-30) during 2.1 update

iTunes could not sync ^0 to the iPhone "iPhone" because an unknown error occurred (-30).
Restarting the installation did not help.
Rebooting my XP machine and then restarting the installation did not help.
I eventually had to go into DFU mode, restore (erasing all of my downloaded apps, movies, music, TV shows, ebooks, etc - almost 16 GB worth) and then let it try to restore. Then I got an error that my backup was corrupt, so I had to start over completely from scratch with a new profile.
All of this took... quite a while.
I have never had to do this for an update before, and am not especially happy about it.

Also, FWIW, my phone is fully operational now - it was just quite a hassle to get there. My husband, who has pretty much the same setup as I do, but only uses his for web browsing and email, had zero problems installing 2.1 earlier today.
Considering my last iphone (2G) shattered (twice!), I may have to consider the fact that I'm just cursed.
(Also, this phone (3G) has never been dropped.)

Syncing ipad, ipod and iphone to a new itunes library

Hi,
I need some guidance on how to achieve what is in my mind a relatively common problem... how do I sync my iPad, iPod (x2) and iPhone to a new computer without having to erase everything.
The scenario is as follows. I have one iTunes library on an old PC. In my family we have an iPad, 2 iPod Touch's and an iPhone, all synced with that machine and that one account. The old PC has seen better days, so I have bought a new machine. I thought it was as easy as just installing iTunes, copying the music over, downloading the apps with my apple id, and bob's your uncle.
Guess not, the first time I plug in the iPad it says that I need to erase the darn thing. You can imagine the drama in the house... one is about to lose their Smurf farm, the other is about to lose their levels in Angry birds, etc, etc. Don't worry about my contacts and emails, nobody cares about that. It's all the data that is stored with the various apps of the various members of my family that has everyone up in arms.
So my question is how can I basically make this whole lot work with my new computer? I am sure that I am not the first one buying a new computer, so I am (hopefully) sure that Apple has build this bit of logic somewhere in their software and devices. Just can't find it, and judging by the amount of blogs, articles and posts dedicated to this it appears that there are a couple of million other people that are equally unable to find this bit of functionality.
Please help... my kids and the wife are not allowing me to get rid of this old PC until this is resolved.
Thanks.

This is copied from another thread. I think it is pretty clear. Here is the link to the thread as well. You will need to do this for each device if they all have different content on them.
https://discussions.apple.com/message/11527071#11527071
1) Without connecting your iPad to your laptop, start iTunes. Click on Edit. Click on Preferences. Click on Devices. Check the box next to "Prevent your iPod etc. from automatically syncing." Click OK.
2) Now connect your iPad to your laptop and start iTunes.
3) When iTunes starts, right click on your iPad under Devices in the left column. Select Transfer purchases etc.
4) After it finishes transferring all your apps to your new laptop, right click on your iPad and select Backup your iPad.
5) After it finishes backing up your iPad, right click on your iPad and select Restore etc.
6) After it finishes restoring, left click on your iPad , then click on the Apps tab on top, and check the box next to Sync Apps, then click on Apply below.
If everything on your iPad looks good after the sync, go back and click on Edit / Preferences / Devices and UN-check the box next to Prevent your iPod etc. The only other thing you may want to check is if your contacts, bookmarks, etc. are syncing correctly now. If not, go to the Info tab after connecting and make sure you indicate which features you want to sync with what sources.
If you have more questions, post back.

My itunes freezes when syncing my ipad. can anyone please help?

I have a 3rd gen Ipad with version 6.1.3 installed and Itunes 11.0.2.26 installed. I am trying to connect my ipad to my laptop (windows 7). Each time I connect the USB cable, Itunes recognizes the ipad and trys to connect to it. As it trys Itunes freezes and i canot do anything. (if i am listening to music it wil continue until that song is done) The rest of my computer is fine and not frozen. Itunes will eventually get to the point where it will show a little picture of the ipad instead of the circular loading symbol. But at that point itunes is completely frozen and i can't even open any menus. If i then unplug the ipad, itunes will free up like nothing happened. i have tried reinstalling itunes, restarting my computer, resetting the device manager, restarting my ipad, tried all of my USB ports, tried connecting with my Wireless internet disconnected, and probably a few more things i can't think of, oh and when i run the diagnostics, it tells me that there is no ipad detected. And when i am plugged in, my ipad charges for a split second then says it is not charging in the top right corner. Help?

I was able to get my iPad synced just now by going into the control panel and accessing "Services". This is located in the "Administrative Tools".
There you will find a service called "Apple Mobile Device". Select that service and you should see options on the left side of the window to stop or restart the service. I stopped it, started it again, and I was able to sync my iPad, finally.
I saw the instructions for this on another thread. I tried to find it again to post a link for you, but no luck.
In the meantime I also set up the iPad backup to go to the cloud rather than my PC. This also seemed to be less taxing on the system when syncing. I don't know which action enabled me to sync (for now), but something worked.
It's somewhat infuriating. Let me know if you find out anything else. I need documents on my iPad for work, and if I can't load them on there it has become a very expensive and heavy paperweight.
Cheers!

Itunes freezes when syncing iphone

I've just got a new pc laptop 64bit windows 7, have downloaded the latest 64bit itunes and have a brand new 32Gb 3GS iphone.
When I attempt to sync my iphone, itunes freezes and I have to close it using task manager. I have read on the internet other ppl have had this problem.. but so far haven't found a fix that works for me.
I've tried re-installing itunes and have restored factory settings on my iphone (frustratingly), but nothing seems to work.
Any help would be greatly appreciated.
Cheers.

SOLVED for me. I had the exact same problem and spent countless hours deleting apps, reinstalling Itunes etc on two windows based laptops and a new iMac. I was ready, after months of this, to go into an Apple store when I found a post on a website suggesting leaving the Iphone connected for hours. I connected my Iphone 3Gs, made sure nothing else was running and that the system wouldn't power down under my power saving settings. As usual Itunes froze (says "not responding" under "force quit" or ctrl-alt-del) but I walked away and the next morning - tada - Iphone was recognized and no problems since then. So give it a shot - I wish I had known it was that easy - all these months of rebooting and trying to find the solution online ! Lynn

ITunes freezes when syncing to my iPhone 4S with Windows Vista 32 bit.

I have downloaded the newest version of iTunes after deleting the previous version.I tried connecting my iPhone 4S 16 gig, iPod Touch, and my iPhone 3GS and with each device, iTunes freezes and will not sync completely with any device. My operating system is Windows Vista, 32-bit

I'm attaching the print screen of iTunes again (as referred in the original post).

IPod (and iTunes) freezes when syncing large playlists

My ipod freezes when updating a large playlist or a lot of new songs. This usually requires me to physically disconnect the dock connector and reconnect the ipod.
If i try to sync the same files using a smaller playlist the ipod is usually able to update.
Anyone else experience this problem and/or have a fix for it?
I've tried resetting/updating software on my ipod with no luck.

Back up all data.
Triple-click anywhere in the line below on this page to select it:
~/Library/Application Support/SyncServices
Right-click or control-click the line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Quit the application if it's running. Move the selected item to the Trash. Relaunch the application and test.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

ITunes Freezes when Syncing on Windows 7 SP1

iTunes seems to freeze imediatly when plugging in my iPhone 4, and will unfreeze soon as I unplug it. This started happening soon as I upgraded to SP1 on Windows 7.
There seem to be many many threads on this and most eventually come to the conclusion that iTunes is not fully compatible with Windows 7 SP1. Calling tech support just told me that it wasnt a known issue.
Ive tested this on 2 seperate systems with 2 seperate fresh installs of Windows 7.
With a Fresh install of Windows 7 and iTunes, synching works.
Install SP1, synching still works for the most part
Install any of these AV's: Microsoft Security Essentials, Nod32 (v4 or 5) or Kaspersky and Syncing is broken. (Trend Micro Titanium worked)
If you uninstall SP1 everything works fine, and compatibility mode fixes it for the most part too. Too many top AV's including Microsofts own are effected by this that it is not a conflict/fault on their part. Some people dont seem to need the AV part of the equation to run into this issue.
Many other reports are listed in the following thread and ones in the "More Like This" section to the right of it. Other AV's causing conflicts since SP1 are listed too.
https://discussions.apple.com/thread/2762816?start=0&tstart=0
The Freezing apon connection of an iPhone (then unfreezing iTunes soon as its removed) has been something that would happen to me very rarley (like once a month, if that) since my 3gs, but now it happens every time. It seems SP1 adgitated that already existing bug in iTunes.
Anyone using Windows 7 SP1 and iTunes with an iPhone or iPod Touch with or without issue? (Standard iPods seem to not be effected) What AV (if any) are you using?

Have you tried iTunes 10.4.1.10? That seems to have fixed it for me when nothing else did. (Of course, I can't be sure that was what fixed it. I just noticed that one day the problem had gone away when nothing else worked, and it seemed to coincide with the upgrade to 10.4.1.)
And it is too a known issue. Sigh. I worked with support on this over the course of a couple of months, sent them logs, spent hours on the phone, etc. I know the engineers knew about it. Whether they ever figured out the cause is another matter.
