DFU stands for Device Firmware Update, and it’s the deepest type of restore you can do on an iPhone. An Apple lead genius taught me how to put iPhones into DFU mode, and as an Apple tech, I’ve done it hundreds of times.
Surprisingly, I’ve never seen another article explain how to enter DFU mode the way I was trained. A lot of the information out there is just plain wrong. In this article, I’ll explain what DFU mode is, how firmware works on your iPhone, and show you step-by-step how to DFU restore your iPhone.
If you’d rather watch than read (actually, both can be helpful), skip down to our new YouTube video about DFU mode and how to DFU restore an iPhone.
What You Need To Know Before We Begin
- The Home Button is the circular button below your iPhone’s display.
- The Sleep / Wake Button is Apple’s name for the power button.
- You’ll need a timer to count to 8 seconds (or you can do it in your head).
- If you can, back up your iPhone to iCloud, iTunes, or Finder before put your iPhone in DFU mode.
- Macs running macOS Catalina 10.15 or newer use Finder to DFU restore an iPhone.
How To Put An iPhone 7 Or Older In DFU Mode
- Plug your iPhone into your computer and open iTunes if you have a Mac running macOS Mojave 10.14 or a PC. Open Finder if you have a Mac running macOS Catalina 10.15 or newer. It doesn’t matter if your iPhone is on or off.
- Press and hold the Sleep / Wake Button and Home Button (iPhone 6s and below) or the volume down button (iPhone 7) together for 8 seconds.
- After 8 seconds, release the Sleep / Wake Button but continue to hold the Home Button (iPhone 6s and below) or the volume down button (iPhone 7) until your iPhone appears in iTunes or Finder.
- Let go of the Home Button or volume down button. Your iPhone’s display will be completely black if you’ve successfully entered DFU mode. If it’s not, try again from the beginning.
- Restore your iPhone using iTunes or Finder.
How To Put An iPhone 8 Or Newer In DFU Mode
A lot of other websites give false, misleading, or overcomplicated steps when telling you how to DFU restore an iPhone 8 or newer. They’ll tell you to turn off your iPhone first, which is completely unnecessary. Your iPhone does not have to be off before you put it in DFU Mode.
If you like our videos, watch our new YouTube video about how to DFU restore your iPhone or newer, including the iPhone 13. If you prefer to read the steps, the process is actually a lot easier than they make it out to be! Putting your iPhone in DFU mode starts off just like a hard hard reset.
- Quickly press and release the volume up button, then quickly press and release the volume down button, and then press and hold the side button until the screen goes black.
- As soon as the screen turns black, press and hold the volume down button while continuing to hold the side button.
- After 5 seconds, release the side button while continuing to hold the volume down button until your iPhone shows up in iTunes or Finder.
- As soon as it appears in iTunes or Finder, release the volume button. Ta-da! Your iPhone is in DFU mode.
Note: If the Apple logo is appearing on the screen, you held down the volume down button for too long. Start the process over from the beginning and try again.

Check out our new YouTube tutorial on how to put an iPhone into DFU mode and how to perform a DFU restore if you’d like to see it in action. In this video, we also show you how to get your iPhone out of DFU mode and debunk some misinformation about DFU restores.
A Word Of Warning
When you DFU restore your iPhone, your computer erases and reloads every bit of code that controls the software and hardware on your iPhone. There’s the potential for something to go wrong.
If your iPhone is damaged in any way, and especially if it’s water-damaged, a DFU restore may break your iPhone. I’ve worked with customers who tried to restore their iPhones to fix a minor problem, but water had damaged another component that prevented the restore from completing. A useable iPhone with minor problems can become completely unusable if a DFU restore fails because of water-damage.
What’s Firmware? What Does It Do?
Firmware is the programming that controls the hardware of your device. Software changes all the time (you install apps and download new email), hardware never changes (hopefully, you don’t open your iPhone and rearrange its components), and firmware almost never changes — unless it has to.
What Other Electronic Devices Have Firmware?
All of them! Think about it: Your washing machine, dryer, TV remote, and microwave all use firmware to control buttons, timers, and other basic functions. You can’t change what the Popcorn setting does on your microwave, so it’s not software — it’s firmware.
DFU Restores: All Day, Every Day.
Apple employees restore a lot of iPhones. Given the option, I’d always choose a DFU restore over a regular or recovery mode restore. This isn’t official Apple policy and some techs would say it’s overkill, but if an iPhone has a problem that can be resolved with a restore, a DFU restore stands the best chance of fixing it.
Thanks for reading and I hope this article clarifies some of the misinformation on the internet about how to enter DFU mode and why you’d want to use it. I encourage you to embrace your inner geekiness. You should be proud! Now you can tell your friends (and kids), “Yeah, I know how to DFU restore my iPhone.”
My I Phone is stuck on Verifying updates and can’t get it off to do anything. What do I do?

Hello and Thanks for the great video on putting an iPhone in DFU mode. I’m 59 yr. old grammy, married to a genius businessman, who had to go to work this morning, leaving me to figure this out on my own! LOL (one day he won’t be here, so I should probably figure things out on my own now!) Thanks for helping this grammy!

Back in january of this year i shattered my iphone 7 plus screen. I wasnt able to get a screen replacement till recently. i have charged the device since january! i did the replacement how i was supposed to, but the issue i have now is that the phone doesnt cut on. i did research and found that if the phone body vibrates but the screen is black then its the screen replacement but it hasnt vibrated, so im thinking that i left the phone dead for so long itll take a long time to charge up. if anyone has… Read more »
with my 11, I changed out the broken screen for a new one, and it did the same thing, wouldn’t turn on or anything. Then we did a hard reset (volume up/down then hold power button till apple logo comes on) and it worked just fine.
Well I kinda have a big problem…. Long story short I obtained this iPhone 6 from a friend that got it from someone who owed him money for their addiction to drugs.. well I had this phone now for a couple of months and I’ve lost contact with him but whoever he got it from has the find my phone thing on it.. it’s activation locked.. so how can I go about this
After tearing my hair out for days and wasting hours talking to Apple Support I tried this DFU reset. It worked an absolute treat. Thanks for saving my life LOL

Thank you sooooo much for this article. The DFU saved my phone without having to hire someone. a Millions thanks!!!!
Thanks for this updated article. I used an earlier version of your article about a year ago to restore my iPhone 6s. It worked a treat. Two things about this current article: 1. The ads on this page are obnoxious!!! I understand that you need to be paid for your expertise. Surely there is a better way! The page keeps refreshing and I lose my place while reading/typing. Most annoying! 2. Would you please make a note for future readers about just how long it takes for iTunes to download the software and restore the phone when one doesn’t have… Read more »

have an iphone 6s dfu mode but home button not working? please help
iPad Air 2020 stopped working overnight unexpectedly. Tried an update then restore now I’m stuck in a restore loop. It only powers on to tell me to restore it which I’ve done several times now. Otherwise dead. Seems like dfu would be the next step but can’t find how to attempt this with air. Also don’t think I have iTunes anymore just “music”?? Thanks
iTunes got replaced with the Music app a while ago.
Hello Nick, any updates? I have a 7th gen ipad that experienced the same issue. Took it to apple and since it was out of warranty they estimated the fix to run around $300. I will try the DFU process today.
Nick look for Finders on ur air. that’s what you gonna make use of instead of itunes
I just bought an iPhone 5s from a friend of mine, but the phone cannot connect to App Store, please how can that be fixed?

How do I restore the phone to factory settings to be able to use it again. ?
Check out our other article that explains what to do when your iPhone is disabled.

Hice una copia de seguridad con ITunes de mi IPhone 5S. Después restablecí y borré todo los datos. Luego con ITunes quise restaurar la copia de seguridad y horror! ITunes me avisa que no puede activarse porque no ha podido obtener la información de activación del dispositivo. He probado en modo DFU y empieza bien todo pero casi terminando me vuelve a decir el mismo aviso de ITunes. Me estoy volviendo loco!
iPhones have the be the worst sort of device. I’m forced to use one for work, and ever since I upgraded from the 8 to an XR, then an 11, and now a 12, I’ve had the same issues. 1st, the speakerphone being activated right as you put it on your ear. No telling how much damage this has done to my ear drum. It not only activates the speaker, but it seemingly amplifies the sound. From one end of an isle in the big box supermarket to the other, I had a lady that heard what was being said… Read more »

The same thing is happening to me! My carrier and Apple support have not been able to figure it out, was trying this DFU restore but I can’t seem to get into DFU mode… did you ever find a solution?
Dear David, thank you so much for your article. I did not do a dfu but your site was the only place that actually said you have to leave your phone off at least a minute. I read so many help articles and kept doing everything it said, and did soft resets and all but nothing would work. After your ariticle i left my phone off for more than just a minute, I kept it off while if finished reading the whole article and all the comments and then i turned my phone back on and it worked. So happy… Read more »
Siri has stopped working. I have repowered. Turned Siri off and on, location services are on, etc. Reset the airplane off on and off. Just upgraded to 15.4 as well. Any ideas
hello my iPhone was a bypass and when i resetted it, it couldnt go back to home screen
I recently changed password for an app that was Face ID activated.
Since Face ID does not work on app.
I checked Face ID in settings and it is no longer listed as an app using Face ID. Short of DFC reset I have checked everything else including reinstalling app. Can you help me?
so Tried regular and DFU, it is stuck at the apple logo. Phone was almost full, tried to delete stuff, then was using sorting out how to backup pics and ids on windows. On the old Macs I used Image Capture and thus I could sae my ids this way.
My iphone 12 plus says disabled and connect to itunes. How do i fix without knowing my icloud or apple id?
My iPhone says Touch ID is not activated
Try going to Settings -> Touch ID & Passcode on your iPhone. Make sure the switch next to iTunes & App Store or iPhone Unlock is on, and that you have set up one or more fingerprints on your iPhone.
