There are still lots of people who don’t have a clue about DFU Mode or how to enter / exit DFU mode on iPhone. However even if you do have a clue about DFU mode you can still find this article interesting and might even learn a few things that you didn’t know.
Well DFU mode represents a state that helps you interface your iPhone, with iTunes, but it doesn’t load the boot loader nor the operating system of your iDevice. Also for those of you who don’t already know DFU stands for Device Firmware Update.
The main reason why you have to access DFU mode on iPhone is to change the firmware on their iDevice. This comes in real help if you either need to downgrade to an older iOS version or you just need to create a custom firmware in order to jailbreak or unlock your iDevice. For example if you own an iPhone and you want to have an older iOS version you will need to go through iPhone DFU Mode in order to accomplish that.
Step 1: Using a micro USB-cable connect your iPhone to your computer.
Step 2:
Step 3: Turn iPhone OFF.
Step 4: Hold down both Home and Sleep/Power buttons for 10 seconds, than release the Power Button but keep holding down the Home Button until a message pops up. The message should look like the on in the image below, revealing that iPhone recovery mode has been detected.
Step 5: You will know you are in iPhone DFU Mode when the display screen goes completely black.
Congratulations you are now in iPhone DFU Mode. Take notice that if you see the Apple logo, iTunes logo or any other message on your screen that means that you are no longer in DFU Mode, you are in standard Recovery Mode. Basically if you don’t have a black screen you are out of DFU Mode and you need to do the steps all over again.
This isn’t such a hard thing to do, one of the easier ways to exit DFU Mode on iPhone is to hold down both Home and Sleep/Power buttons while your iPhone is connected to iTunes. After that just press the power button and your iPhone should restart as usual.
