How do you put iPhone in dfu mode?

To get your iPod touch out of DFU mode you have to hold the power button for 2 seconds and then while you are still holding the power button hold the home button with the power button for 15 seconds and then let go of the power button and wait until an Apple shows up on your screen and there you go oh and when you do that all of your games and other apps will still be on there so dont worry. hit me up on YouTube type in Lil Dre Lil coo yo mama jokes and theres more the one on the left is me the one on the right is my friend Cooper bye.
