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.

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!

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

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.

IPhone 5 stuck at recovery mode. Can't recover, unknown error (2001).

I've upgraded my 3GS to an iPhone 5 about 3 weeks back, and I was resonably happy with the 6.0.1 installed.
After upgrading to 6.0.2, the battery in my iPhone 5 began to drain and could only last for a maximum of 4-5 hours. I've tried it all, tweaking the settings to conserve power, even tried some solutions posted on other forums, restoring back to factory settings, doing a soft reset, hard reset, even tried redownloading the iOS 6.0.2 and I think the worst just happened ...
Battery died (cuz I'm out of power right.)
Charged it to Apple's USB power outlet.
Stuck at Apple boot logo, wouldn't proceed but instead it tries booting again, and again, and again....
So I tried a hard reset, and put it into DFU mode, hopefully it will be stable again after recovery.
Plug my iPhone back to my Mac OSX 10.8.2, iTunes tries to unpack the OS and attempts the restore...
Instead, it's now stuck at the recovery mode, and iTunes gives me, "The iPhone cannot be restored. an unknown error occured (2001)."
And then, the iPhone attempts to restart, goes back to connect to iTunes mode (DFU) and the cycle then repeat itself again.
Any of you guys having the same issue? I can't seem to find a fix anywhere

I've sent it in to my local telco to get a replacement because I simply can't find another way around it.
Has anyone tried with the new iOS update to 6.1.0? Let me know if it works. I'm still waiting for a replacement from Maxis (Apple's Authorised iPhone after sales support here in Malaysia).
They have a stupid policy of waiting up to 2 weeks before I get a replacement. At the meantime, Maxis just expects me to be phone-less for 2 whole week although they have prepared back-up iPhone5 stocks for a 1on1 exchange. Their reason: Oh, we cannot read your IMEI no, we need to send it back to the distributor.
This frustrates and furiates me. Why can't Apple Malaysia be more professional about it like how it's done in U.S.?
Gahhhhhhhh....

HT201210 unknown error (9)

hi all,
im having trouble restoring my iphone. its shows unknown error (9) and exit from the restore process. any help?

Error 9
This error occurs when the device unexpectedly loses its USB connection with iTunes. This can occur if the device is manually disconnected during the restore process. This issue can be resolved by performing USB troubleshooting, using a different USB dock-connector cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.

HT201210 Unknown error occurred (-1)

Hi,
I just upgraded my iPad to IOS6 but unfortunately there is an error message " The iPad"iPad" could not be restored. An unknown error occurred (-1)".
Please advise for the solution of this error.
Thanks.

Hello ale3ulla,
Sorry to hear that you are stuck with the same error. Looking into that specific error code, it may be an issue with the hardware. Try it a few more times and make sure that there is not any conflicting software that may be causing it as well as making sure that iTunes is up to date. You may end up needing to contact Apple Support.
Get help with iOS update and restore errors
https://support.apple.com/en-us/HT204770
Check for hardware issues
Errors: 1, 3, 11, 12, 13, 14, 16, 20, 21, 23, 26, 27, 28, 29, 34, 35, 36, 37, 40, 53, 1002, 1004, 1011, 1012, 1014, 1667, or 1669.
Your device or computer might have a hardware issue that stops the update or restore from completing.
Check that your security software and settings aren't blocking your device from communicating with the Apple update server.
Then try to restore your iOS device two more times while connected with a cable, computer, and network you know are good.
Make sure that your security software and settings are allowing communication between your device and update servers.
If you still see the error message when you update or restore, contact Apple support.
If you still see the error message, check for outdated or modified software.

HT201210 Unknown error occurred (24)

I am trying to restore my iphone4s and at first i encountered unknow error 3004, after trying all the solutions available online & numerous attempts
i was able to get pass thru it, thinking that i can finally restore my phone but to my dismay I have encountered yet another problem which is unknown error 24.
The solution given to error 3004 & 24 is the same, how come i encounter the same error?
This error solution is almost close to none. I hope you can help me out on this problem.
Thanks.

Thanks for the reply. I have tried these tips already but to no avail.
For additional information on my problem. I am actually restoring using DFU mode coz my phone
is practically dead (i.e. doesn't charge and battery seems off) however, when i start connecting to itunes
it recognizes that its in restore mode then after extracting the software, then verying the iphone and my phone already displays the apple sign on the screen, the unknown error occurred (24) appears.
I have been searching about this error but nothing really addresses this erro 24 in particular.
I have used two computers already, both showing the same problem.
Do i need to change my phone now?? Why do i feel like it can still be fixed, somehow. Just don't know how.

HT201210 Unknown error 40?

Phone went completely black screen except for green line straight down the middle and faded to white. Finally was able to turn back on after 2 hours and now tells me to plug into itunes but then itunes says cannot restore and gives me unknown error 40. Has anybody experienced this?

Hello Seabee1980,
Thank you for the details of the issue you are experiencing with your iPhone. I recommend the following steps for the issue you described:
Check for hardware issues
Try to restore your iOS device two more times while connected with a cable, computer, and network you know are good. Also, confirm your security software and settings are allowing communication between your device and update servers. If you still see the alert when you update or restore, contact Apple support.
Common errors: 1, 10-47, 1002, 1011, 1012, 1014, 1000-1020.

HT201210 unknown error (23)

I got the message "cannot restore due to unknown error (23)" on itunes. Does anyone know what I do now? My phone is blank and when I unplug and plug back up I get the picture plug , arrow, and itunes .

These errors typically occur when security software interferes with the restore and update process. Use the steps to troubleshoot security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See the steps under the heading "Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store." If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart.
