DFU mode stands for Device Firmware Update mode. It’s a special state you can put your iPhone XR into. DFU mode lets you make deep changes to your iPhone’s software. It’s a powerful tool but use it with caution.
DFU Mode Explained: Restore and Troubleshoot
When to Use DFU Mode

Before You Start
Before you start, make sure you have the following:
- A computer (Mac or Windows) with iTunes installed. If you’re using a Windows PC, make sure it has the latest version of iTunes.

Entering DFU Mode on iPhone XR
Entering DFU (Device Firmware Update) mode on an iPhone XR is a crucial step for deeply troubleshooting device issues or applying updates at a system level.
Prerequisites for DFU Mode
Before starting, one must ensure that they have the following items:
- An iPhone XR with enough battery charge to complete the process.
- A working Mac or PC with the latest version of iTunes installed.
- A genuine Apple USB cable. Third-party cables may not always work.
Step-by-Step Guide to Enter DFU Mode
Follow these steps to put your iPhone XR into DFU mode:
- Connect the iPhone XR to the Mac or PC using the USB cable.
- Open iTunes or Finder if using macOS Catalina or later.
- Turn off the iPhone XR.
- Press and quickly release the Volume Up button.
- Press and quickly release the Volume Down button.
- Hold down the Side button until the screen turns black, then hold down both the Side button and Volume Down button together for 5 seconds.
- Release the Side button while continuing to hold the Volume Down button until iTunes or Finder alerts that a device in recovery mode has been detected.
During this process, the iPhone XR’s screen should remain black if done correctly. If the Apple logo appears, restart the steps, as this indicates that you are not in DFU mode but in the regular recovery mode instead. It is important to follow the timing of the button presses accurately to achieve DFU mode.
Restoring iPhone XR in DFU Mode
When an iPhone XR is unresponsive or facing serious software issues, restoring it in DFU (Device Firmware Update) Mode can be a powerful solution. This process involves using iTunes on a PC or Finder on a Mac to reinstall the iOS operating system from scratch.
Restoring iPhone with iTunes/Finder
To restore an iPhone XR using iTunes or Finder:
- Open iTunes on a PC or Finder on a Mac running macOS Catalina or later.
- Connect the iPhone XR to the computer using a Lightning cable.
- Enter DFU Mode by:
- Quickly pressing the Volume Up button.
- Quickly pressing the Volume Down button.
- Pressing and holding the Side button until the screen turns black.
- Without releasing the Side button, press and hold the Volume Down button for 5 seconds.
- Release the Side button but continue to hold the Volume Down button until iTunes or Finder detects a device in recovery mode.
- Follow the on-screen prompts in iTunes or Finder to Restore the iPhone. This will download the latest iOS firmware and completely erase all data on the iPhone.
Before restoring, it’s crucial to have a backup of the iPhone’s data, either on iCloud or a computer, to prevent data loss.
Potential Issues During Restore
Several issues could arise during the restore process:
- Computer not recognizing the iPhone: Make sure the Lightning cable is good and the USB port is functioning.
- Error messages: If iTunes or Finder displays an error message, this could indicate a connection issue or a problem with the iPhone’s hardware.
- Long download times: If the firmware is taking too long to download, check the internet connection and consider downloading it when the network is less congested.
Patience is key during a restore, as interrupting the process can cause further issues. If trouble persists, contacting Apple Support or visiting an Apple Store may be necessary for additional help.
Exiting DFU Mode on iPhone XR
Exiting DFU (Device Firmware Upgrade) Mode on your iPhone XR is usually straightforward. The process involves a force restart, which is a handy troubleshooting step for various iPhone issues.
Troubleshooting DFU Exit Issues
If your iPhone XR is stuck in DFU Mode, you might need to perform a force restart. Here’s how to execute a force restart on your device:
- Step 1: Press and quickly release the Volume Up button.
- Step 2: Press and quickly release the Volume Down button.
- Step 3: Press and hold the Side button until you see the Apple logo, then release the Side button.
Your iPhone XR’s screen should power down then restart, indicating you have successfully exited DFU Mode. If a normal restart doesn’t work, it could be a hardware issue, in which case contacting Apple Support or visiting an Apple Store may be necessary.
When iTunes is involved, and your iPhone XR is connected to a computer, you should remove the device from DFU Mode to prevent any accidental firmware changes. This is important because DFU Mode allows for altering the firmware, which is more in-depth than the standard operating system interactions.
If the above steps don’t resolve the issue, you might consider restoring the iPhone XR using iTunes. But remember, this will erase all data on your device, so it should be a last resort:
- Connect your iPhone XR to a computer and open iTunes.
- Follow the prompts on iTunes to restore your iPhone.
After the restoration, your iPhone XR will exit DFU Mode and boot up to the setup screen. Remember to always keep your iPhone updated to avoid software glitches that might necessitate entering or exiting DFU Mode.
