First:  Put the device into DFU mode.

 

DFU MODE STEPS

 

  1. Hold the Power Button (3 secs)
  2. Continue holding the power button and also hold the home button (15 secs)
  3. Release the power button while continuing to hold the home button (10 secs)
  4. Your device should prompt with the "Connect to iTunes Screen"

 

 

Second: Plug it into your computer and open iTunes. It will either prompt to restore and up date or you can manually restore using the following steps.

Restoring your iOS device

  2. Select your iPhone, iPad, or iPod touch when it appears in iTunes. Select the Summary tab, and click the Restore button.
  3. Click Restore.
  4. After a restore, the iOS device restarts. You should then see "Slide to set up". Follow the steps in the iOS Setup Assistant.
  5. If needed, restore your device from a previous backup.

    DFU mode is signified by having a completely black screen on the device.

    Connect the iPhone to your computer and launch iTunes. Turn the iPhone off (hold down the power button at the top of the iPhone).

    Hold down the sleep/power button and home button together for exactly 10 seconds, then release the power button.

    Continue to hold down the Home button until a message appears in iTunes telling you an iPhone in recovery mode has been detected by iTunes.

    Thanks jermainepaul! I had an iPhone 5 with an expired iOS 7 Beta that would not restore no matter what I tried. I suspect a prior user may have jailbroken it. I must have tried at least 20 times to restore using the latest 7.1 ipsw downloaded from Developer Center. I kept getting Error 3194.

    I went into DFU mode following your directions and then the restore worked perfectly the FIRST time! Many thanks!!

    DFU mode is not needed unless trying to repair a previously hacked/jailbroken phone or for hacking.  Recovery mode should be used and is safer:
