Cannot Restore Unknown error 2001

iTunes says it cannot restore my iTunes and has an Unknown Error 2001. It all started after it failed the new update. Any ideas?

Hi amigos:
Same happen to me as soon as the new release (1.1.3). Sounds weird but the only think you have to do is plug and unplug your iPod 3 0r 4 times.
I can assure you that after 4 or 5 tries everything will be ok.
Why is happening that?
Think Apple sold so many iPod (4,000,000) and we are trying to get it at the same time, so they cant handle to manage all of them. Maybe there is not as much slot as they need for everyone to download the new version. Because you cant download the new release your iPod don't get the new software while the old one is deleted.
Believe me, try to plug/unplug 4 or 5 times at the problem will be solve. Or much better, just next time don't try to upgrade as soon as the new release is on iTunes and wait 1 week

My iphone 4 shut down today only get the apple logo and usb connect to itunes logo. Tried to restore in dfu mode and restore mode but keep getting error codes 2001 21. Is there a solution?

No info on "error 2001", but for error 21 on a PC - temporarily disable all security software (firewall, antivirus, etc.) running on your PC when updating or restoring.
"Error 20, 21, 34, 37: These errors typically occur when security software interferes with the restore and update process. If you are using a PC, follow this article to resolve this issue."

Hi there Katherine,
I have an article here that addresses this error code and can give you a few more troubleshooting suggestions for this issue:
Resolve specific iTunes update and restore errors
http://support.apple.com/kb/ts3694
Check USB connections
If there’s an issue with the USB port, cable, dock, or hub, or if the device becomes disconnected during restore, try troubleshooting the USB connection, then troubleshooting your security software.
Common errors: 13, 14, 1600-1629, 1643-1650, 2000-2009, 4000, 4005, 4013, 4014, 4016, “invalid response”, and being prompted to restore again after a restore completes.
To narrow down the issue, you can also change up your hardware:
Use another USB cable.
Plug your cable into a different USB port on your computer.
Try a different dock connector (or no dock).
Add (or remove) a USB hub between your device and computer.
Connect your computer directly to your Internet source, with no routers, hubs, or switches.
If you see your error after changing your USB connections, continue to the next section to troubleshoot your hardware.
Thanks for coming to the Apple Support Communities!

Errors 2000-2009 (from Apple support): If you experience this issue on a Mac, disconnect third-party devices, hubs, spare cables, displays, reset the SMC, and then try to restore. If you are using a Windows computer, remove all USB devices and spare cables other than your keyboard, mouse, and the device, restart the computer, and try to restore. If that does not resolve the issue, try the USB issue-resolution steps and articles listed for Error 1604. If the issue persists, it may be related to conflicting security software.
Error 2001
The Mac OS X kernel extension "IOUSBFamily" that was bundled with late 2008 / early 2009 MacBooks, as well as the 10.5.6 update, has a bug where it fails to properly recognize an iDevice in DFU Mode. It can be resolved by updating to 10.5.7 (or later), or using a USB hub.

Unknown error (2001)

I'm sorry if this question has been posted and answered before. I've been having problems with iTunes. At least i think it is ITunes because all of the iPods in my household seem not to be able to connect with iTunes. Anyways my problem: i downloaded the new update for my touch that lets me run apps. While installing the update iTunes suddenly stopped citing an unknown error. When i went to Restore and Update to get my touch running again, it gives me the unknown error (2001). So now currently i can not do anything with my touch because it will not restore. I have reinstalled itunes too many times, and still it does not help. And now currently my computer will not even recognize the device. Any help would be appreciated in getting my touch working again with the update.

Are you syncing photos to the ipod? If so, the -39 in this context can sometimes indicate a damaged photo cache. Are you able to sync if you delete your existing photo cache? To find it, see the following document:
iTunes: Understanding the iPod Photo Cache folder

Cannot Restore iPad2 - Error Code 3173?

Never had an issue with an Apple product before.
Windows 7 Home Premium
iTunes 10.5.0.142
iPad 4.3.5
Attempted to update iPad software to 5.0 and got the error code "cannot restore iPad - error code 3173"
Freaked out and disconnected the iPad and it seems fine, no data/information loss and it DID NOT update as it is still running version 4.3.5.
No other external USB ports in use, never had an issue updating previously.
Thoughts/ideas/fix? Seems like a lot of people are posting asking for help with this but I don't see a fix anywhere.

Good idea. I wish I had waited. My iPad2 will not Restore so it is hammered. My iPhone 3Gs is updating now so we'll see. But this is definately an Appple problem as all 5 devices at our house had one issue or another. My iPad2 fails with the unrelated error 1162. The USB driver does not install. For my iPhone 3Gs, the USB driver installed and the update is nearly complete. Oh, it's backing up now. I'll just have to see if it works but it is going much better than our iPads. The iPads seem to be the big issue.
