Hello jijojohn,
After reviewing your post, I have located an article that can help with devices that need to be restored. It contains a number of troubleshooting steps and helpful advice for the issue you are experiencing:
If you can't update or restore your iPhone, iPad, or iPod touch
Use recovery mode
You might need to use recovery mode to restore your device in these cases:
iTunes doesn't recognize your device or says it's in recovery mode.
You see the Apple logo onscreen for several minutes with no progress bar.
You see the Connect to iTunes screen.
Learn what to do if you see the progress bar onscreen for several minutes.
To put your device into recovery mode, follow these steps:
Turn off your device and leave it off.
Plug in your device's USB cable to a computer with iTunes. 
Hold down the Home button on your device as you connect the USB cable. Keep holding down the Home button until you see the Connect to iTunes screen.
When you see this screen, release the Home button. If you don't see this screen, try steps 1 through 3 again. 
When your device is connected, iTunes will open. You'll see a message saying that iTunes has detected an iPhone, iPad, or iPod touch in recovery mode.
Use iTunes to restore your device. Restoring in recovery mode will erase your device. If you previously synced with iTunes or iCloud, you might be able to restore from your backup.
Get more help
Learn what to do if you don't see your device in iTunes for OS X, or in iTunes for Windows.
If you put your device into recovery mode by mistake, restart it. Or you can wait 15 minutes and your device will exit recovery mode by itself.
Thank you for contributing to Apple Support Communities.
Cheers,
BobbyD

    Are you running modified software on your phone?  This error seems to be common if the firmware has been modified and you're trying to restore the phone again. 

  • When we  try to restore a iphone 3 sur Itunes and new Lion we have error 3194 can t restore this iphone what can i do ?

    when we  try to restore a iphone 3 sur Itunes and new Lion we have error 3194 can t restore this iphone what can i do ?
    thanks for your kind help

    1. Update iTunes - latest version is 10.4.1.
    2. Disable ALL security apps (firewall, antivirus/spyware) running on your computer.
    3. Don't try to downgrade the iOS version.  This isn't supported
    4. If you EVER tried to hack thie phone or use apps like tinyumbrella, you may have to edit the hosts file on your computer to remove references to gs.apple.com
    5. If your phone has been hacked (jailbroken, iOS downgrade, or unauthorized unlocking), you may not be able to restore the phone to Apple specs again.
    "This device is not eligible for the requested build: Also sometimes displayed as an error 3194. If you receive this error, update to the latest version of iTunes. 3rd party security software or router security settings can also cause this issue, to resolve please follow Troubleshooting security software issues. Downgrading to a previous version of iOS is not supported. If you have installed software to perform unauthorized modifications to your iOS device, that software may have redirected connections to the update server (gs.apple.com) within the Hosts file. For steps to edit the Hosts file and allow iTunes to communicate with the update server, see  iTunes: Troubleshooting iTunes Store on your computer, iPhone, iPad, or iPod; follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > The hosts file may also be blocking the iTunes Store.  Also, using an older or modified .ipsw file can cause this error. Try restoring moving the current .ipsw file aside, or try restoring in a new user to ensure that iTunes downloads a new .ipsw."

  • I get a 3914 error when I try and restore my iphone 4. my screen goes white and then all different colors. what should I do?

    i get a 3914 error when i try and restore my iphone 4. my screen goes white and all different colors  what should i do

    first try a different usb cable, remove all other usb devices, and try a different port in back on desktops if possible.  if no luck see these
    These errors typically occur when security software interferes with the restore and update process. FollowTroubleshooting 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 iTunes: Advanced iTunes Store troubleshooting—follow 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.

  • Receiving an error 3194 whenever I try to restore my iphone

    Hello,
    I have a iPhone 5
    I am using windows 7 professional (32 bit) and the latest Itunes software.
    Whenever I try to restore my iphone I receive an error 3194 message.
    I follow apple's instructions and added to host (system32\drivers\etc) the following lines:
    74.208.105.171 gs.apple.com
    It didn't fix anything and I receive the same error notification.
    Please help!

    Apple's instructions for fixing this error are here: Error 3194, Error 17, or "This device isn't eligible for the requested build" - Apple Support
    Nowhere does Apple suggest adding that line to the Hosts file. In fact, Apple suggests just the opposite.
    Also read the other two sections of the above article.

    Did you try the things listed here? Error 3194, Error 17, or "This device isn't eligible for the requested build" - Apple Support  Is your device jailbroken? Have you ever used the computer to jailbreak a device? Are you trying to load an iOS other than the current one? What version of iPhone are you using? Is this occurring when attempting to update via iTunes and the computer?
