I am asked constantly how to put the iPhone in DFU mode. I always answer people and explain them how to do it but I figured after all this time, writing a post about how to put your iPhone in DFU mode was long overdue.

In most cases, you’ll need to put your iPhone in DFU mode during the jailbreak process. It’s pretty easy but it’s all about perfect timing…

Step 1: Launch iTunes.

Step 2: Plug your iPhone in your computer via the USB cable.

Step 3: Turn off your phone.

Step 4: Hold the Power and Home button together for exactly 10 seconds.

Step 5: After 10 seconds, release the Power button and keep holding the home button until iTunes tells you it has detected your iPhone.
