Understanding DFU Mode on the iPhone 12
Device Firmware Update (DFU) mode is a special state your iPhone 12 can enter when you need to interact with the iOS system at a deeper level. It’s a step beyond the standard recovery mode and allows for a more comprehensive restoration of the device.
When to Use DFU Mode
DFU mode might be necessary when:
- Your iPhone 12 is stuck, and normal restarting doesn’t work
- You are attempting to install a previous version of iOS
- The phone needs a complete reset for troubleshooting
How to Enter DFU Mode
To put your iPhone 12 into DFU mode:
- Quickly press the Volume Up button.
- Quickly press the Volume Down button.
- Press and hold the Side button until the screen turns black.
- While still holding the Side button, hold the Volume Down button for 5 seconds.
- Release the Side button but keep holding Volume Down for another 10 seconds.
Your screen should remain black if done successfully. If you see the Apple logo or any other display, you will need to start over.
Exiting DFU Mode
Exiting DFU mode can be done by:
- Pressing the Volume Up button.
- Then, pressing the Volume Down button.
- Finally, holding down the Side button until you see the Apple logo.
This simple process restarts your iPhone 12 normally, taking it out of DFU mode. Remember, using DFU mode correctly can fix various issues, but it should be used responsibly and ideally, only when other standard troubleshooting methods have failed.
Entering DFU Mode on the iPhone 12
Entering DFU (Device Firmware Update) Mode on your iPhone 12 is a crucial step for restoring your device through iTunes or Finder if it’s not working correctly.
Preparation
Before attempting to put your iPhone 12 into DFU Mode, it’s important to ensure that you have the latest version of iTunes installed on your computer if you are using a Mac with macOS Mojave or earlier or a PC. For Macs with macOS Catalina or later, iTunes is not required as the Finder handles device management. Also, ensure that your iPhone 12 is fully charged or has at least a decent amount of battery life to prevent it from turning off during the process.
Steps to Enter DFU Mode

- Connect your iPhone 12 to your computer with a Lightning cable.
- Quickly press and release the volume up button.

- Press and hold the side button on your iPhone 12 until the screen turns off.
- Continue to hold the side button, and after 3 seconds, start holding the volume down button as well.
- Hold both buttons for 10 seconds. If the Apple logo appears, you’ve held them for too long and will need to start over.
- Let go of the side button but keep holding the volume down button for another 5 seconds. The screen should remain black.
If the screen stays black, congrats! Your iPhone 12 is now in DFU Mode. If it does not stay black, repeat the steps above. Remember, timing is essential when entering DFU Mode. Once in DFU Mode, your computer should detect your iPhone and you can follow your computer’s prompts to restore your device.
