The iPhone 14 lineup has arrived and with that, it’s handy to know how to access its utility modes in case you run into any issues. Read on for how to force restart iPhone 14, use recovery mode, and perform a DFU as well as when to use these different options.

In many cases, if you’re seeing unexpected behavior from your iPhone, a simple restart will do the trick. That’s just powering off your device and powering it back on (press and hold the side button and one volume button > slide to power off or Settings > General > Shut Down > slide to power off).

However, if you can’t do that, here are your next steps…

How to force restart iPhone 14, use recovery mode, or DFU

Note: The steps below also work for iPhone 8 and later, including iPhone SE gen 2

Force restart iPhone 14 and 14 Pro

This is the best option if your iPhone touchscreen isn’t working and/or you can’t power it off/on normally to fix a frozen or unresponsive device:

Press and quickly release the volume up button
Press and quickly release the volume down button
Press and hold the side button until the Apple logo appears, then let go
Your iPhone should restart shortly
Recovery mode for iPhone 14 and 14 Pro

Use recovery mode if a force restart doesn’t work or if you see a blue or red screen while your iPhone is restarting or it freezes during startup:

In rare cases when recovery mode doesn’t work, entering device firmware upgrade (DFU) mode may be the next step. This is usually something an Apple Genius/technician will do but you can perform it from home.

Connect your iPhone to your Mac or PC with a Lightning cable
Select Trust on your iPhone screen to allow the connection to your computer, then open Finder in macOS Catalina and later or iTunes for PCs/macOS Mojave and earlier
Press and quickly release the volume up button
Press and quickly release the volume down button
Press and hold the side button for 10 seconds
While continuing to hold the side button, press and hold the volume down button for 5 seconds
Let go of the side button and continue holding the volume down button for an additional 10 seconds
There is no computer icon when entering DFU mode – when you’ve properly entered it, your iPhone display should stay black. If the Apple logo appears, you did not perform the process correctly
Follow the prompts on your computer to complete the device firmware update
You can exit DFU mode by performing a force restart
via Apple
Other situations
If you can’t perform a force restart or enter recovery mode or DFU mode because you have broken buttons, are stuck at Activation Lock, or can’t charge your iPhone, get in touch with Apple Support
