This tutorial will show you how to put your iPhone into DFU Mode. Use DFU Mode to downgrade firmware to older version. DFU mode is not the same as Recovery Mode. You should always try Recovery mode first to solve your iPhone issues because its easier. You can read our previous post How to Put iPhone into Recovery Mode? In case you were wondering about the difference between these two modes refer to iPhone Tip: Difference Between Recovery Mode and DFU Mode.
If your iPhone is dead and doesn’t startup at all you can put your iPhone into DFU mode by following the tutorial and then restore it using Apple’s Firmware Files(.ipsw)
How to put your iPhone into DFU Mode?
Follow these steps carefully.
Step 1: Connect your iPhone to your computer.
Step 2: Turn your iPhone off. You have to do this after connecting since iPhone automatically turns on every time you connect it to the computer.
To turn off press and hold the power button till you see the “Slide to Power off” screen. Now slide the button to turn it off. In case your iPhone is stuck in an infinite loop and the previous option is unavailable, press and hold the Power and Home button till the screen goes off.
Step 3: Hold Power & Home Button together for 10 seconds. Release Power button but continue holding Home button till your iPhone starts and iTunes detects it. The iPhone screen will remain black and no logo or image should appear.
In case you see the Connect to iTunes screen(2nd Screenshot shown above) on your iPhone you are in Recovery Mode and not DFU. People who are used to jailbreaking their iPhones should be able to do it one attempt. Novice users might take three or four attempts before they get it right. Don’t worry you won’t spoil your iPhone so it’s okay to try.
How to Exit DFU Mode?
If you somehow find yourself stuck and need to exit DFU Mode just hold both Home and Power buttons for five seconds or till the iPhone restarts(Apple logo appears).
Apart from iPhones, you can also use this tutorial to put iPod Touch into DFU Mode or an iPad too. If you need more help, feel free to ask us via comments.
