In order to enter DFU mode, your device must be connected to a computer with the USB cable. Make sure that iTunes is running. Hold the Power button for 5 seconds. After the first 5 seconds, press and hold the Home button while continuing to hold the Power button. Do this for 10 seconds or until the screen darkens. After exactly 10 seconds of holding both buttons, release the Power button but continue holding the Home button. After a few seconds, a message will appear in iTunes letting you know that the device has been detected. The device’s screen will remain blank if done successfully.
