Step Two
Press and retain the Home button and the Sleep/Wake button at the matching time.

Step Three

NOTE***: It may take a small number tries to get your iPhone into DFU mode. Generally, I retain down both buttons then distribute the Home button just before I consider the Apple logo would appear. If you are still keeping both buttons down and you observe the Apple logo you are keeping them down for too long!
