How To Put An iPhone In DFU Mode & DFU Restore An iPhone [2023]

David & David show you how to put an iPhone in DFU mode and perform a DFU restore. DFU stands for device firmware update.

A DFU restore is the deepest type of iPhone restore. It's the last step on the road to determining whether a software problem is causing whatever issue you're having on your iPhone. If a DFU restore doesn't fix it, it's usually a hardware problem.

Before putting an iPhone DFU mode, it's very important to create a backup. A DFU restore erases and reloads every line of code on your iPhone. Without a backup, you'll lose all of your data and information.

📱 How To DFU restore an iPhone 8 or newer: Plug your iPhone into your computer and open iTunes (on a PC or Mac running MacOS 10.14 or earlier) or Finder (on newer Macs). Quickly press and release the volume up button, then quickly press and release the volume down button, then press and hold the side button until the screen goes black.

When the screen goes black, press and hold the volume down button while continuing to hold the side button. Hold both buttons for five seconds, then release the side button while continuing to hold the volume down button. Keep holding the volume down button until your iPhone appears in Finder or iTunes. Finally, click Restore iPhone.

What do you think about Elon Musk buying Twitter?

Totally clicked to find out what DFU stood for because in my mind I could only come up with “Don’t F*uck Up” mode.

You guys are ABSOLUTELY fantastic! I often refer customers to your channel for techniques to use with their devices. I also learn a thing or two myself. Bravo David & David!

[themullinator]

You guys saved us a trip to apple with my wife’s phone. She was getting the bootloop/4013 error and this took care of it. Thank you very much!

[saraann]

I’m doing all the steps but once I release the side button the Apple logo pops up and the phone turns back on. Idk why it’s not work when I’ve done it before

[leocui]

Might've been said already but if you're on a Mac, do not try this with the USB C to Lightning cable, it will not work. Use the USB A (big rectangle) to Lightning cable instead. I'm not sure why this is but I wasted an hour and a lot of frustration to find this out.

Things have evolved since this video. The latest version of iOS, iPadOS, and macOS allows you to DFU Update, rather than do a DFU Restore. An updated video on this topic would be welcomed.

Amazing my iPhone is back to life. THANK YOU SO MUCH! Super helpful video.

[josephkaneene]

Thank you. I had an issue where I upgraded my iphone xr using itunes, but I still had the "Unable to check for update error". So this was my last resort and it fixed the problem

[docholliday]

Wow thanks guys, didn't know I could make this happen. However you guys are the apple experts not me. Great video.

[EffortlessEthan]

Imagine having all of the instructions for this process on one screen so it's not incredibly tedious to perform while watching the video. Incredible concept I know.

[kiwiriauk]

Tried my sim in another phone and it works - didnt have anyone willing to put their sim in my phone though so - im at the DFU bit in your video now cuz nothing else worked - scarey but gonna try it

[BrianPrince]

The toughest part is that people don’t do the last step long enough. The rule is 10 seconds, but “hold until it shows up in iTunes” is more like it. In my experience, it can take as long as 30 seconds.

[jonathanbailey]

Man your videos so good I managed to do it first time as well.... And I am nearly, PS love the studio set up

[ruizd]

Recommendations, can you give an instruction video on how to simply put things on iCloud & how to secure it? I have iPhone 6+Thanks. I’m sure it’s pretty easy for the majority of this channel.

[jullianahunter]

Do you have to use a Apple laptop or can it be any type of laptop?

[sarafisk]

Mine doesn't show up on my finder before the logo comes up. I've tried a ton of times, checked my cord and then tried again. Any recommendations?

[chaselauner]

For anyone a little confused (at least I was and I had a few tries before I figured it out) In step 3 they say to press and release the side button and continue to hold the VOLUME DOWN BUTTON, when i did mine, I had to press both down and the release the VOLUME DOWN BUTTON so i was still holding the side button, at the end of the video I watched you hold down the VOLUME DOWN BUTTON and then say to release the side button, so anyone in confusion I hope this helps, press both, release volume down button and continue to hold the side button until this pops up!

[cabernetguy]

Love your informative videos!

A question though: You used the DFU with a Mac.
What about the rest of us who use a PC?? And not, I am not buying a Mac just for the

[daveboy]

Hope you can answer this very important Question, we know it's best to just charge your iPhone battery to 80% as that causes less wear on your battery, ok if you buy a brand new iPhone, should you use it before charging it and let the battery go down to zero and shut off, then charge it to 100% and then after that Obay the 80% and 20% battery rule, please do a video about this, especially for people who buy a brand new iPhone.
