How to enter iPhone DFU mode?
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 recover mode has been detected by iTunes.
