DFU Mode is an essential tool in the iDevice arsenal. Device Firmware Update is different than the recovery mode. DFU mode allows your phone to interact using iTunes without the phone operating system (iOS) loading.
For most problem solving, recovery mode is what folks use. But sometimes that just doesn’t work out–that’s where DFU comes in!
You also need the DFU mode when you are trying to downgrade the iOS version or un-jailbreak it.
Things are a bit different for accessing DFU Mode on iPhone X Series phones and iPhone 8 models. Let’s take a look.
It’s easy to think your iPhone is in DFU mode when it isn’t!
When the iPhone enters into DFU mode, you ALWAYS see a blank black screen on your iPhone.
DFU Mode on iPhone XS/XR/X and iPhone 8 Step by Step
Update to latest iTunes version on your computer FIRST
Close any open apps on your phone (if possible) and on your computer
Power on your phone (if needed)
Connect Your iPhone to your Computer using the Lightning Cable
Launch iTunes and make sure that your iPhone shows up in the list of devices
Next, Press the Volume UP button followed immediately by the Volume DOWN button
Now, Press and hold the Side or Power button until the iPhone screen turns black
Your screen should stay black, if not go through the previous steps again
Release the Side or Power button and press down both the Side or Power button AND Volume DOWN button together for 5 seconds or so
After 5 seconds, release the side or power button but keep pressing the Volume Down button
Give it a few seconds, around 10, until iTunes recognizes the DFU mode and check that your screen remains black
If you successfully entered the DFU Mode on your device, your iPhone’s screen should remain black and you see a message on your computer that “iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes.”
If not, repeat these steps
If you do not see a black screen, you are not in DFU Mode. Please run through these steps again.
You’re in DFU Mode if your screen is completely black
Sometimes during the process, you may accidentally enter recovery mode or your iPhone simply turns off.
Please try the steps again and you will be successful.
To exit the DFU mode on your iPhone XS/XR/X or 8, simply turn off the device.
We hope that you do not ever need to get to the DFU mode on your brand new iPhones.
