How To Put Your iPhone 6 , 6S or 7 Model Into DFU Mode

Posted by Repair Media on

DFU mode, or Device Firmware Update, can be used to update the firmware on your iPhone, completely restoring the software. It’s perfect for when your iPhone fails to co-operate and is unresponsive.


You’ll want to carry out a Device Firmware Update if the standard restoration using Recovery Mode fails to work for you. A DFU is a last resort.

What Is Firmware?


Firmware is software that sits between the hardware, your iPhone, and the software, which is the iOS operating system. Firmware is used to provide a variety of functions at hardware level. It is firmware that starts up the iOS software when powering up your iPhone. Therefore if you try to update or restore the firmware, it can help to fix a completely unresponsive iPhone.


The Steps To Take To Put Your iPhone In DFU Mode


Step 1: Attach your iPhone to your computer using the USB cable, and make sure iTunes is running on your computer


Step 2: Hold down both your home button and your sleep/wake button simultaneously. Keep holding these down together for exactly 10 seconds.


Step 3: After the 10 seconds release your finger from the sleep/wake button but continue to hold down your home button for another 10 seconds.


Step 4: Release your finger from the home button only once iTunes pops up with a message saying it has detected an iPhone in Recovery Mode.


Your iPhone screen should remain completely black.


NOTE: If you see the apple logo on your screen, you’ve held your buttons down too long; keep trying until the iTunes message pops up.


Step 5: Your iPhone will now appear in ‘devices’ in your iTunes account. Click the ‘restore iPhone’ button.


How To Exit DFU Mode


Simply hold down your home button and the sleep/wake button simultaneously until you see the Apple logo appear.
