See this one from Apple Support Doc.
Error 2000-2009 (2001, 2002, 2005, 2006, 2009, and so on)
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 above. If the issue persists, it may be related to conflicting security software. If the errors persist on another computer and known-good USB cable, the device may need service.

HT201210 What is Unknown error 2001, iPhone could not be restored.

These error message is not listed in common issues for iPhone 4 trouble shooting. Does any one knows what is about, or any approach to solve this matter?

Close iTunes and unplug iphone
Search web and download the 2.2.1 ipsw file.
Go to device manager on PC and delete the USB option for Apple under the hardware options.
Reboot PC
Plug in iphone and wait for dreaded connection picture
hold power button and home button until apple logo appears
continue to hold home button and release power button until connection picture appears again
Your PC should now find the iphone in recovery mode
Now open iTunes and it will prompt you to restore
Hold the shift button on the keyboard and click the restore button at the same time
This will allow you to browse for the correct ipsw file
select the 2.2.1 file that you downloaded
your iphone will now restore
Once completed, you will need to resync
Now you are back to square one but at least have a phone that works
Now make an appt at the Genius Bar and make them update it for you
Mine is scheduled for next week

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.

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.

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....

Help - Unknown Error 2006 "iPhone could not be restored"

Hi there - has anyone else been plagued with this? I tried to sync my iPhone 3G (less than a year old) and it wouldn't sync. I tried to restore it and it went partially through the process and bailed returning an error. I went to the discussion boards who recommended (not necessarily in this order) rebooting, using a different USB cable, a different computer, reinstalling iTunes, turning off Little Snitch, turning off Firewall, using an on-board USB port. Absolutely NOTHING worked and my phone is bricked. Now, despite everything all I get is "iPhone" could not be restored An unknown error occured (2006).
Can anyone help?

Help, iTunes error 2001, iPhone stuck on Apple logo!

HELP!!!!!!! THIS IS DRIVING ME INSANE.
Okay, so recently I accidentally dropped my phone in the toilet (it was an accident, slipped out of my butt pocket as I was pulling my jeans down) and then did the rice trick and whatnot. After two days, I tried to turn it on again and it wouldn't work. Then, i plugged it into the recharger and MIRACLE OF MIRACLES the apple logo flashed! Then nothing more happened, it kept flashing on and off, and wouldn't respond to any buttons. So then I connected it to my macbook, and iTunes popped up saying that it'd detected an iPhone in recovery mode. however, to restore it I would have to download the newest iPhone software but I didn't have the ability to do that just yet so I unconnected it.
Now today i was finally able to download the software, but everytime I connected my iphone to mac itunes never picked it up. Eventually, following the advice of everyone on the internet, I 'put it into DFU mode' or something, (im not sure what I did, once I got a black screen that was still detected by itunes, and every other time i've got the itunes logo and a charger symbol).
Then i got really excited, followed all the onscreen prompts, until it finally said waiting for iPhone and then ERROR 2001 APPEARS! Further more, the iPhone isn't even called what I called it, but called iPhone, 'iPhone'. I've tried restarting everything, trying different ports, but nothings working, every time I just get to error 2001!
So i would really appreciate it if someone could help me! I don't care about losing files or anything, i just want it functional again.

Hi there, I had a very similar problem to yours. I ended up getting my iPhone 3GS quite wet. On top of that, some of my casing is broken (near the power button), so a lot of water got inside.
At first, there were a lot of changes to the screen, and eventually the phone simply died. It just wouldn't turn on. And then all of a sudden, the same day, it randomly switched on, and i could hear some 'sizzling' sound inside. Following this, it just kept rebooting.
At this point, I unscrewed the screws at the bottom and opened up the phone (but didn't disconnect anything). Instead of using the rice trick/silica gel etc, I just placed a fan facing pointing at the inside, and let it sizzle away, and hoped that the heat from the sizzling battery and the air from the fan would dry it soon.
It did dry - soon the sizzling stopped, and the phone just kept rebooting. The battery eventually died by the next day. So I put it on charge, and it eventually switched on, in recovery mode (USB picture and iTunes symbol).
The next thing I noticed was that the battery held almost no charge. As soon as I disconnected it, the phone would die, immediately. Same thing if you connect it to the computer. On top of that, my Mac did not recognise the iPhone at all.
Next, I cleaned out the dock with the sharp end of a safety pin and loads of fluff came out. And after re-connecting it a few times, iTunes recognised it. So I tried to restore it, but a few various errors came up, and eventually, error 2001 kept coming up. Which apparently means there is something wrong with the USB or dock. (My USB is fine, the phone dock is messed up).
So next I tried to force the phone out of recovery mode. Pressing the buttons does nothing. No program works, except RecBoot for Mac. But even on that, as soon as the phone restarted, it died immediately and went back to recovery mode.
So I took it off the computer and let the battery die again, and then charged for another 24 hours.
Now at this stage, the phone seems to hold a bit of charge for a while. And iTunes is randomly recognising the phone. And it lets me restore it. And it even lets me restore the iTunes backup!! But after it has everything restored, the phone reboots one more time and iTunes says not to disconnect it... And now it's back in recovery mode.
I'm going to keep on trying. I think it's partially down to luck and I would recommend you do the same. I'll post an update here if it works.

Unknown error (46) iPhone 3Gs

My friend's iPhone 3Gs is in restore mode and each time I try to restore it I get the message
"The iPhone "iPhone" could not be restored. An unknown error occurred (46)."
I have tried all number of things. Sometimes the code is (47), but 99% of the time the error is (46)
The iPhone will not restore, Software recognises it, but it will simply not restore. I have had this phone previously for a similar issue and I was able to fix it by performing some actions which I can't recall now. I think the code was different that time, but there was some messing about in the registry involved from memory. If anyone can help My friend would appreciate it!
So would I too...
Thanks in advance,
Rudolph

Hello All,
My iphone 3 shut itself down. I tunes would then try to restart the phone, but when it got to the point of saying "contacting the phone" the error message number 46 would come up. So frustrating,
To fix it:
1. I did a unexpected shut down of my computer (holding the power button).
2. I re opened itunes.
3. I connected my home to itunes.
4. I pressed and held the home (bottom button on iphone) and the top button on the iphone, at the same time.
5. After exactly ten seconds I released the top button (your iphone screen may be blank and the phone will disconnect from itunes).
6. I then held the home button (I think thats what it's called, it's the only buttom on the face of the iphone), I held this button until the phone was re-recognized by itunes.
7. I then followed the itunes promts to restore and was elated when it worked. (I also pressed home a couple times out of pure frustration at the point when the iphone screen has a apple on it with a progress bar on the bottom, but I don't think that effected the process.)
I think the real change in the process that worked for me, was putting the phone in DFU mode after the phone was already connected to itunes (DFU process described in steps 4-6).
All the best, LP

HT4623 unknown error 1156 when trying to sync after updated to ios 6 - help?

I got a message on itunes - unknown error 1156 - when trying to sync after I updated to ios 6 . Anybody else had the same thing?

Hey greenleas_c,
Welcome to the forums.

HT4623 unknown error occured (11556)

my iPad shows "cannot connect to iTunes Store". My PC shows "iTunes could not connect to the iTunes Store. An unknown error occured (11556). Make sure your network connection is active and try again.".
I think that it will be helpfull if there was an app that is able to find issues. This app makes log and forwards it securely to Apple Tech Team or generates a solution.

IIIaass is right on the money! Specifically, please go to this page for error 11556 (in most cases, this should solve the error 11556): http://support.apple.com/kb/TS3288
It's that (I found this myself yesterday, after weeks of helplessness in solving the error 11556) whenever iTunes is updated, the Parental Controls in iTunes are, by default, set to 'enabled' mode! One needs to disable/unckeck this on the iTunes menu (under 'Edit' --> 'Preferences' --> 'Parental'). See the relevant discussion/thread here:https://discussions.apple.com/message/22473554#22473554
