Errors 3000-3999 (3004, 3013, 3014, 3018, 3164, 3194, and so on): Error codes in the 3000 range generally mean that iTunes cannot contact the update server (gs.apple.com) on ports 80 or 443. 
Update to the latest version of iTunes.
Verify the computer's date and time are accurate.

Follow Troubleshooting security software. Often, uninstalling third-party security software will resolve these errors.
An entry in your hosts file may be redirecting requests to gs.apple.com (see "Unable to contact the iOS software update server gs.apple.com" above).
Internet proxy settings can cause this issue. If you are using a proxy, try without using one.
Test restoring while connected to a known-good network.

Error 3014 may indicate that you need to free up more disk space on the computer before trying to restore again.

    Check for hardware issues
    Related errors: 1, 3, 10, 11, 12, 13, 14, 16, 20, 21, 23, 26, 27, 28, 29, 34, 35, 36, 37, 40, 1000, 1002, 1004, 1011, 1012, 1014, 1667, or 1669.
    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 error message when you update or restore, contact Apple support.

  • TS3694 Hi the iphone iphone could not be restored. an unknown error occurred (56). what mean that?

    Hi the iphone iphone could not be restored. an unknown error occurred (56). what mean that?

    More than likely a hardware issue.  You will need to take your phone into Apple.
    You can also use the search function type error 56 and you'll see other threads about the issue.   You can read for yourself, if other solution will help.

    Instructions to get the phone back working temporary.. till there is a real fix.
    1. turn off the phone
    2. fire up iTunes
    3. press and hold the home button, plug in the cable, hold till you get to see the recovery mode
    4. iTunes will the allow to choose restore the phone back to 5.0.1 ( no other choice)
    5. iTunes will then ask you to choose which previous backup to would like to recover.
    (note: please do not reboot your phone unless necessary, i realize at times after reboot, it goes back to sq1)

  • The iphone could not be restored. an unknown error occurred 1015

    Hello everyone,
    After upgrading to ios 4, my iPhone 3GS is stuck recovery and I am asked to restore it. However the operation cannot complete since at the end I get an error message that " the iphone could not be restored. an unknown error occurred 1015". What should I do? I am not close to any apple store and I cannot go there? Also, does the warranty allows me to get this fixed?
    Thanks in advance

    So that means that there is no way this thing can get fixed? How about degrading the ios 4.3 to 4.2? Is there any legal way to do that? Any comment/help is appreciated
    P.S: I was thinking about jail breaking it since it is the only way that Google is suggesting. Would that be a better approach since I am tired of living with out a phone?

  • "the iphone could not be restored an unknown error occurred (2)"

    Yesterday I connected my iPhone 4 to my Windows 7 laptop, and went through to install the latest security update for iPhone through iTunes. When it was installing the software update, the phone froaze, and then this happened:"the iphone could not be restored an unknown error occurred (2)"
    Now, I have uninstalled and reinstalled both Bonjour and iTunes, to no avail. I have done the iPhone reboot method, and the phone will be identified as "iPhone" but not recognised as mine. iTunes states this phone is in recovery mode and I have tried numerous times to restore it.
    Windows doesn't detect the phone while this is happening. It will not restore and the error is still popping up. I have followed as many threads to rectify this but nothing seems to be working.
    I can resore it on my iMac but the reset date for the iPhone on this computer is six months old.
    Any suggestions?

    When you say you uninstalled iTunes and reinstalled it, did you follow the directions in this Apple support document exactly? http://support.apple.com/kb/HT1923
    That will make a difference on Windows computers. After that, try and reconnect and restore.

    My iPhone 3GS 16gb, is stuck in restore mode, downloaded and tried to do a restore multiple times. Keep getting an error The iPhone "iPhone" could not be restored. Unknown error occured (-1). Cannot get it out of restore mode, keeps rebooting!
    I have tried to hold the "home" and "power" button to reboot
    I have tried powering it off
    I have tried, to unplug the cable, hold the "home" button and then plug it in.
    Can't check the SN or warranty, cause it is stuck in restore mode.
    Is the hard drive gone? Should there be something replaced.

    Error 1 or -1
    This may indicate a hardware issue with your device. Follow Troubleshooting security software issues, and restore your device on a different known-good computer. If the errors persist on another computer, the device may need service.
    Usually this is caused by your antivirus or firewall blocking iTunes access to the Internet. It can also occur if the phone is jailbroken or if the computer you are using was ever used to jailbreak an iDevice.

    If you want to solve your problems, unjailbreak. And don't do it again, because jailbreaking causes problems as you read about in that article. You can try Recovery Mode: http://support.apple.com/kb/HT1808

    the iphone could not be restored. an unknown error occurred (1015).

    Error 1015: This error is typically caused by attempts to downgrade the iPhone, iPad, or iPod touch's software. This can occur when you attempt to restore using an older .ipsw file. Downgrading to a previous version is not supported. To resolve this issue, attempt to restore with the latest iPhone, iPad, or iPod touch software available from Apple. This error can also occur when an unauthorized modification of the iOS has occurred and you are now trying to restore to an authorized, default state.
