DFU Mode stands for Device Firmware Update Mode. It is the deepest restore state available on an iPhone, iPad, or iPod touch — deeper than Recovery Mode — because it allows your device to communicate with iTunes, Finder, or the Apple Devices app without loading the iOS bootloader (iBoot) or the operating system itself.
Here's what that means in practice: when your iPhone is in DFU Mode, the firmware can be reloaded from scratch, even if the software on the device is severely corrupted. That's why a DFU restore can rescue devices that Recovery Mode cannot.
The screen stays completely black. This is the defining visual sign of DFU Mode. If you see the "Connect to iTunes" or cable-and-computer icon, your device is in Recovery Mode, not DFU Mode.
It operates at the hardware level. DFU Mode is built into the SecureROM/BootROM burned into the device's chip, so it cannot be removed or disabled by software.
Your computer will detect the device as being "in recovery mode" and offer to restore it — this is normal and expected.
Reload the firmware and restore an iPhone that won't boot
Fix a bricked iPhone or iPad stuck in a boot loop
Downgrade iOS to an earlier version (while Apple is still signing it)
Perform a DFU restore when a standard restore in Recovery Mode fails
Bypass iCloud Activation Lock
Install unsigned or custom iOS versions
Fix hardware failures (broken screens, water damage, faulty batteries)
Many users confuse DFU Mode with Recovery Mode because both connect your device to a computer for restoring. However, they work at different levels of your iPhone's startup chain.
Recovery Mode loads the iBoot bootloader and displays a "Connect to computer" screen. It's designed for routine restores and updates. DFU Mode bypasses iBoot entirely and talks directly to the hardware — the screen stays black, and the restore happens at the firmware level.
| Comparison | DFU Mode | Recovery Mode |
|---|---|---|
| Bootloader | Bypasses iBoot | Loads iBoot |
| Screen display | Completely black | "Connect to iTunes/computer" icon |
| Restore level | Firmware/hardware-level | Software-level |
| iOS downgrade | Supported (signed versions only) | Not supported |
| Difficulty to enter | Harder (precise button timing) | Easier |
| Data risk | High (typically full erase) | Medium (Update option may keep data) |
| Best used for | When Recovery Mode fails | Routine restore, update failures |
| Apple official support | No (undocumented) | Yes |
Which one should you use? Always try Recovery Mode first — it's easier to enter, officially supported by Apple, and offers an "Update" option that may preserve your data. Only move to DFU Mode if Recovery Mode fails to restore your device, your iPhone is stuck in a boot loop, or you need to downgrade iOS.

If your iPhone won't turn on past a black screen, gets stuck on the Apple logo, or freezes during an iOS update, a DFU restore reloads the firmware from scratch and can bring a seemingly dead device back to life.
Installed an iOS beta that's full of bugs? DFU Mode lets you restore to an earlier stable iOS version — but only while Apple is still signing that version. Once Apple stops signing it, downgrading is no longer possible.
When Recovery Mode restores keep failing with errors (like iTunes error 4013 or 4014), DFU Mode bypasses the corrupted bootloader that's causing the failure and allows a clean firmware reinstall.
An iPhone stuck in a boot loop — endlessly restarting — usually can't be fixed by a normal restore. DFU Mode breaks the loop by wiping and reloading everything below the operating system.
If a jailbreak attempt goes wrong and leaves your device unbootable, DFU Mode is the standard way to recover, since it ignores all jailbreak modifications and reinstalls clean firmware.
The exact button combination depends on your iPhone model. Apple has changed the button layout three times, so find your model group below and follow the steps carefully — timing is everything when entering DFU Mode.
Back up your iPhone. A DFU restore erases everything. If your device still works, back up to iCloud or your computer first.
Charge to at least 20%. An interrupted restore can cause bigger problems.
Use an original or MFi-certified cable. Cheap cables are the #1 cause of "DFU Mode not working" complaints.
Open the right software. On macOS Catalina or later, open Finder. On Windows or older macOS, open iTunes or the Apple Devices app.
Stay connected to the internet — restore files are several gigabytes.
Applies to: iPhone 8, 8 Plus, X, XR, XS, XS Max, 11, 11 Pro, 11 Pro Max, 12 series, 13 series, 14 series, 15 series, 16 series, and iPhone SE (2nd/3rd generation). Whether you're looking for iPhone 11 DFU Mode, iPhone 13 DFU Mode, iPhone 14 DFU Mode, or the latest iPhone 16 DFU Mode — the steps are identical.
Connect your iPhone to your computer with a Lightning or USB-C cable.
Quick-press and release the Volume Up button.
Quick-press and release the Volume Down button.
Press and hold the Side button until the screen goes completely black.
As soon as the screen turns black, press and hold the Volume Down button while still holding the Side button. Hold both for 5 seconds.
Release the Side button but keep holding Volume Down for about 10 more seconds.
If the screen stays black and your computer shows a message like "iTunes/Finder has detected an iPhone in recovery mode" — you're in DFU Mode. ✅
If the Apple logo appears, you held the Side button too long. If the "Connect to computer" screen appears, you entered Recovery Mode instead. ❌ Start over from Step 1.
Applies to: iPhone 7, iPhone 7 Plus, and iPod touch (7th generation). The iPhone 7 DFU Mode combination is unique — it uses Volume Down instead of the Home button.
Connect your iPhone 7 or 7 Plus to your computer.
Press and hold the Side (Sleep/Wake) button and the Volume Down button at the same time.
Keep holding both buttons for 8 seconds.
After 8 seconds, release the Side button but keep holding Volume Down.
Continue holding Volume Down until your computer detects the device (about 5–10 more seconds).
The screen should remain completely black. If the Apple logo appears, you held the buttons too long — start over. ✅
Applies to: iPhone 6, 6 Plus, 6s, 6s Plus, 5s, 5c, 5, iPhone SE (1st generation), and iPod touch (6th generation and below). These models use the classic Home button combination.
Connect your iPhone to your computer.
Press and hold the Home button and the Lock (Sleep/Wake) button at the same time.
Keep holding both for 8 seconds.
Release the Lock button but keep holding the Home button.
Hold Home until your computer detects the device. The screen stays black — that's how you know the iPhone 6 DFU Mode or iPhone 6s DFU Mode entry was successful. ✅
iPad DFU Mode follows the same logic as iPhone, but the button layout differs depending on whether your iPad has a Home button.
Applies to: standard iPad models, iPad mini (1st–5th gen), iPad Air (1st–3rd gen), iPad Pro 9.7"/10.5"/12.9" (1st & 2nd gen).
Connect the iPad to your computer.
Press and hold the Home button and the Top button simultaneously for 8 seconds.
Release the Top button but keep holding the Home button until your computer detects the iPad.
The screen remains black in DFU Mode.
Applies to: iPad Pro 2018 and later, iPad Air 4th gen and later, iPad mini 6th gen and later, iPad 10th generation. If you need iPad Pro DFU Mode steps, this is your section.
Connect the iPad to your computer.
Quick-press and release the Volume Up button (closest to the Top button).
Quick-press and release the Volume Down button.
Press and hold the Top button until the screen goes black.
Immediately hold the Volume Down button while still holding the Top button for 5 seconds.
Release the Top button, keep holding Volume
Down until your computer detects the iPad in DFU
Mode.
Accidentally entered DFU Mode? Or is your iPhone stuck in DFU Mode and you simply want out — without restoring? There are two ways to exit DFU Mode safely.
The fastest way to get out of DFU Mode is the free Exit DFU Mode tool built into Dr.Fone – System Repair. No button combinations, no timing pressure, no risk of accidentally triggering a restore.
Download and launch Dr.Fone – System Repair on your Mac or PC.
Navigate to Toolbox Repair.
Select Exit DFU Mode.
Follow on-screen instructions to exit.
The tool supports every model — from iPhone 6 DFU Mode issues to the latest iPhone 17 — and exiting DFU Mode this way does not erase any data.
✓ Free feature · No data loss · Under 30 seconds
If you prefer the manual route, a force restart gets your device out of DFU Mode:
iPhone 8 and later / iPad without Home button: Quick-press Volume Up, quick-press Volume Down, then press and hold the Side/Top button until the Apple logo appears.
iPhone 7 and 7 Plus: Press and hold the Side button and Volume Down together until the Apple logo appears.
iPhone 6s and below / iPad with Home button / iPod touch: Press and hold the Home button and Lock/Top button together until the Apple logo appears.
After about 10 seconds, the Apple logo should appear and your device will boot normally. Exiting DFU Mode
this way does
not erase your data — data loss only happens if you proceed
with a full DFU restore.
DFU Mode has a reputation for being tricky — most failures come down to timing, cables, or software. Here's how to fix the most common issues.
Cause: You held the Side button too long before adding the Volume Down button.
Fix: Start over, and press Volume Down the instant the screen goes black. The 5-second dual-button window is the step most people get wrong.
Cause: Your timing triggered Recovery Mode rather than DFU Mode — usually because the final Volume Down hold was too short.
Fix: Don't worry, no harm done. Exit Recovery Mode (force restart) and try the DFU steps again, watching the timing carefully.
Cause: Usually a cable, USB port, or driver issue — not the DFU Mode itself.
Fix: Try an original Apple cable, connect directly to the computer (no USB hubs), switch USB ports, and make sure iTunes or the Apple Devices app is fully updated.
Cause: Outdated software or driver conflicts, especially on Windows.
Fix: Update iTunes to the latest version (or install the Apple Devices app on Windows 10/11), restart your computer, and try a different machine if the problem persists./p>
Cause: A failed restore or deeper system corruption is preventing a normal reboot.
Fix: First try a force restart. If that fails, use Dr.Fone's free Exit DFU Mode tool — it forces the device out of the DFU state at the system level. If the device still won't boot, a full system repair is needed.
Cause: A loose cable connection or accidental button presses interrupt the DFU state.
Fix: Lay the phone flat, use a snug-fitting cable, and don't touch any buttons once connected.
Once your computer detects your device in DFU Mode, click Restore in iTunes or Finder. The computer will download the latest signed iOS version and perform a full firmware reinstall. Keep the device connected and don't unplug it until the process finishes.
This depends on what you do:
Entering DFU Mode alone — no data loss. Your data stays intact.
Exiting DFU Mode — no data loss.
Performing a DFU restore — erases everything and returns the iPhone to factory condition.
If you backed up beforehand, restore from your iCloud or computer backup during setup. If you didn't have a backup, tools like Dr.Fone – Data Recovery can scan your device and backups to retrieve photos, messages, and other files where possible.
DFU (Device Firmware Update) Mode is the deepest restore state on an iPhone. It lets the device communicate with a computer without loading the iOS bootloader, so firmware can be reloaded even when the system is severely corrupted. The screen stays completely black while in DFU Mode.
It depends on your model. iPhone 8 and later: Volume Up → Volume Down → hold Side until the screen goes black → hold Side + Volume Down for 5 seconds → release Side, keep holding Volume Down. iPhone 7/7 Plus: hold Side + Volume Down for 8 seconds, release Side, keep holding Volume Down. iPhone 6s and earlier: hold Home + Lock for 8 seconds, release Lock, keep holding Home.
Force restart your device: iPhone 8 and later — Volume Up, Volume Down, then hold the Side button until the Apple logo appears. Or use Dr.Fone's free Exit DFU Mode tool to exit in one click without any buttons.
Recovery Mode loads the iBoot bootloader and shows a "Connect to computer" screen; DFU Mode bypasses iBoot entirely and shows a black screen. DFU Mode is deeper, supports iOS downgrades, and is used when Recovery Mode fails.
Entering or exiting DFU Mode does not erase data. However, performing a DFU restore erases everything on the device — always back up first.
You can trigger the button sequence without a computer, but DFU Mode is only useful when connected to a computer — its entire purpose is to let iTunes, Finder, or the Apple Devices app reload the firmware.
Yes — DFU Mode allows restoring to an earlier iOS version, but only while Apple is still signing that version. Apple typically stops signing older versions within a few weeks of a new release.
For iPhone 8 and later: hold Side until the screen goes black, then Side + Volume Down for 5 seconds, then Volume Down alone for about 10 seconds. For iPhone 7: Side + Volume Down for 8 seconds, then Volume Down alone. Timing is the most common failure point.
The most common reasons are: releasing buttons at the wrong time, a faulty or non-certified cable, a loose USB connection, or outdated iTunes/Finder software. See the Troubleshooting section above for detailed fixes.
No. A factory reset erases your data through the Settings app while iOS is running. A DFU restore works below the operating system, reloading the firmware itself — it's used when the device can't boot normally at all.
Yes. iPads with a Home button use the Home + Top button combination; iPads without a Home button (iPad Pro 2018+, iPad Air 4+, iPad mini 6+) use the same Volume Up → Volume Down → Top button sequence as modern iPhones. Full steps are in the iPad section above.
Yes. The iPhone 16 series uses the same DFU Mode button combination as all Face ID iPhones (iPhone 8 and later): Volume Up, Volume Down, Side button, then Side + Volume Down. The steps in this guide are fully up to date for iPhone 16 DFU Mode.
