How to resurrect iPhone 3G stuck in Apple Logo

If you have an iPhone 3G that is jailbroken or unlocked, and you accidentally resetted the phone, it will be stuck in the Apple Logo and cannot boot up normally. Here are the steps to get past it.

  • Note the iPhone firmware version that you have before you reset the phone. For example, iOS 4.0.
  • Download the corresponding firmware for your iPhone model from here
  • Edit the windows host file located in "C:\WINDOWS\system32\drivers\etc\hosts". Added the following line:
    74.208.105.171 gs.apple.com
  • Connect the iPhone to the computer. Make sure the battery is charged. Turn off the iPhone. If you cannot turn it off, try hold home button + power button together for a few seconds. Release both buttons as soon as it's turned off. Otherwise the phone will boot up again.
  • Start iTunes. Enter DFU mode.
