HT1688 cannot restore iphone error 2001

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."

  • 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

  • HT4623 when trying to restore my iphone error 2001 pops up. Will not get out of recovery mode

    Battery got extremely hot one day while battery was 100%. When i noticed it was hot battery started draining really fast within 5 min it was dead. Hooked up to computer to charge but would not turn on. Itunes plug in screen pops up and iunes says needs to be restored, but when i try to restore it error 2001 keeps popping up. That was on a mac book, when trying to restore on pc error 21 pops up. Any ideas?

    Maybe:
    Restore loop (being prompted to restore again after a restore successfully completes)
    Troubleshoot your USB connection. If the issue persists, out-of-date or incorrectly configured third-party security software may be causing this issue. Please follow Troubleshooting security software issues. .
    Next try placing in DFU mode and then restoring.

    Then try restoring on another computer.

  • 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.

  • Cannot restore iPhone 5, iOS 6.1.4, error 2001 and 2006

    My iPhone 5 (AT&T, purchased on March 2013) suddenly went blank - without being dropped down, or *drowned* in water/ liquid - then a blinking (Apple) logo ...
    Following Internet forums, I kept the "Home" button pressed a while, the sign of an USB cable attemting to connect to iTunes appeared.
    iTunes asked me to restore, I agreed, it downloaded the "iPhone5,1_6.1.4_10B350_Restore.ipsw", then extracted, then verifying with Apple for a while, then appeared the message that this iPhone cannot be restored, error 2001.
    I retried, same result, sometime the error is 2006.
    I retried with another MacBook Pro, then iMac, same error 2006 or 2001 !
    Strange thing : when trying in iTunes in Windows 8 (via BootCamp on those same iMacs, MacBook Pro), the error changed to error 21 !!!
    I'd tried in several other ways :
    01. DFU (pressing both "Home" and "Power" buttons ... ...),
    02. turn off Intego/ Sophos/ ClamXav,
    03. delete that .ipsw file to download a new one,
    04. remove the iPhoneUpdater.log files, pretending to cheat the system
    05. confirm via System Information that I am plugging the iPhone only to one of the USB Hi-Speed Buses (thinking error 2001 & 2006 relates to USB ports)
    ... the *iFool* beauty keeps sleeping like ... a brick !
    Any help would be highly appreciated. Many thanks in advance.
    BAKZOO.

    Hey guys, i have the same issue.
    Yesterday my iphone lost network, i turned it off, and wanted to turn on, but iphone didn't react.
    Once i plugged charging cable in, apple logo appeared, then screen went black, then apple logo appeared once again. So it seems like iphone goes into reboot after apple logo appears.
    I connected iphone to macbook pro while holding home button, itunes showed me iphone 5 in recovery mode, then iOS was downloaded, but recovery didn't even started. Every time it shows me 2001 error. Sometimes recovery fails with 2006 error. I tried to change USB port, tried another original USB cable, tried another macbook pro, both are updated to OS X 10.8.4, iTunes 11.0.4(4), but the same 2001 error comes up over and over again.
    I did everything that official support advises on this page http://support.apple.com/kb/TS3694?viewlocale=ru_RU&locale=ru_RU#error2001, but nothing really helps
    Any ideas on what might help? There's no Apple stores here in Uktraine so i can not return my iphone and get a new one

  • HT201210 cannot restore iPhone 5s.  error code 40

    I cannot restore my iphone 5s after multiple blue screens and I cannot reset with the home-on buttons together.  I updated all software on my mac as suggested and I still get error code (40).  Any help out there?

    Here's what error 40 can be about:
    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.
    Has the software on your phone been modified?

  • Restore iPhone error 14

    My IPhone 5 suddenly turned off and can not be turned on.
    It prompts me to use connect to iTunes . I have done all iTunes updates but it says it cannot be restored due to error 14.
    It restored correctly once this weekend and functioned for all of an hour before it died.
    I'm afraid I'm within days of the one year  warranty. Because I live in a rural area I can't get to a Rogers or IApple store I cannot conveniently take it in for replacement or repair.
    I've had nothing but problems since I updated to the os7:(

  • IPhone error (2001)

    I've just taken delivery of my new iPhone - all fantastic - had it up and running etc., and then I went to upload the latest update...and all has gone a bit bad...
    This is the process I have been through so far:
    1. Went to download update. Failed - error (2001).
    2. Rang Apple
    3. Created new user
    4. Downloaded update successfully with no problems
    5. Went back to regular user
    6. Unplugged/replugged in iPhone to USB - get message "iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes.
    7. On the screen is consistently an image of a USB with arrow pointing to iTunes icon.
    8. Unplug USB. Hold Home button and replug USB...get same message as above.
    9. Choose Restore and Update (again - tho it did it successfully when I used new user account).
    10. "The iPhone could not be restored. An unknown error occurred (2001).
    11. Click OK - disconnects iPhone from iTunes.
    Any advice?! I've got a case ref. with Apple so I'm going to ring them back too.
    Thanks, Mel

    The answer - plug the USB directly into the Mac - not through a USB hub...!!!

  • Cannot sync iphone error (-50)

    Cannot sync iphone - please help

    Error 13, 14, 35 and 50 (or -50)
    These errors are typically resolved by performing one or more of the steps listed below:
    Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting.
    Put a USB 2.0 hub between the device and the computer.
    Try a different USB 30-pin dock-connector cable.
    Eliminate third-party security software conflicts.
    There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.
    Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.
    Try to restore from another known-good computer and network.
