Step One
Open iTunes and connect the iPhone to your Mac.

Step Two
Press and hold the Home button (the only button on front)  and the Sleep/Wake button(on top right ) at the same time.

Step Three
After exactly 10 seconds release the Sleep/Wake button. Continue holding the home button until  iTunes pops up a message telling you that it has detected an iPhone in recovery mode.

The iPhone screen will remain black at this time, it may take a few attempts to get your iPhone into DFU mode. Generally, hold down both buttons then release the Home button just before Apple logo would appear. Make sure you are not holding down for too long.
