Has your Apple smartphone suddenly turned into a “brick”? Then the first thing to do is to put the device into a special low-level recovery mode called DFU (Device Firmware Update).
What is DFU mode?
DFU Mode– a special low-level device mode that does not use the operating system boot. The USB connection only sends technical information signals to the device.
In the past, DFU mode was mainly used to get a jailbreak on the first versions of the iPhone, iPad or iPod Touch. Currently, DFU mode is only used when restoring an iOS device protected by a password-lock (not to be confused with Find My iPhone Activation Lock), as in recent years hackers have released tools that require minimal user participation.
A device in DFU mode does not display anything on the screen, the display is completely black.
After iTunes on the computer recognizes that the device is in DFU mode, the message " iTunes has detected an iPhone in recovery mode".
Since 2007, as iOS devices have evolved, Apple has changed the input (output) process of iPhone, iPad and iPod Touch to DFU mode three times. At the moment, there are three instructions, each of which corresponds to a specific device.
How to put iPhone 2G, 3G, 3GS, 4, 4S, 5, 5C, 5S, 6, 6 Plus into DFU Mode
1 . Connect your device to your computer with a cable.
2 . Press the buttons at the same time Home + Inclusions until the device screen turns off (10-15 seconds).
3 . After one second, after the screen of the device has gone blank, release the Power button, but continue to hold the Home button for 15 seconds.
After the device is in DFU mode, iTunes or another program you are using will notify you with a message that the device is in recovery mode.
How to get iPhone 2G, 3G, 3GS, 4, 4S, 5, 5C, 5S, 6, 6 Plus out of DFU Mode
To exit DFU mode, simply press and hold down the buttons at the same time. Inclusions And Home for 10-15 seconds until the Apple logo appears on the screen.
How to put iPhone 7 and iPhone 7 Plus into DFU Mode
The iPhone 7 and iPhone 7 Plus are the only Apple smartphones to receive a second modification to the process to enable DFU mode.
1. Connect iPhone 7 to Mac or Windows computer;
3. Turn off iPhone;
4. Press and hold the power button located on the right iPhone for 2 seconds;
5. While holding the power button, press and hold the volume down button located on the left;
6. Hold both buttons for 10 seconds.
7. Release the power button while continuing to hold the volume down button for another five seconds;
8. If the display still remains off, then the device has entered DFU mode. In this case, iTunes will display a notification about the detection of the connected iPhone 7, after which it can be restored (instruction).
Note: If the Apple logo appears on the screen, then you held the buttons for too long and you need to repeat everything from the beginning;
In DFU mode, the screen should not display anything (just a black display).
9. Note: if any logos appear on the screen (Apple, iTunes with cable, etc.), then you have activated recovery mode, not DFU. If it works, great. If not, try enabling DFU mode again.
How to get iPhone 7 and iPhone 7 Plus out of DFU Mode
To exit DFU on an iPhone 7 or iPhone 7 Plus, hold down the Volume Down button and the Power button until the Apple logo appears on the phone screen.
How to put iPhone 8, iPhone 8 Plus, iPhone X, iPhone XR, iPhone XS and iPhone XS Max into DFU Mode

2. Press the Volume Up button on the left sidebar, then release it.
3. Press the Volume Down button on the left sidebar, then release it.

5. Without releasing the Power button, press and hold the Volume Down button for 5 seconds as well.
6. Release the Power button, but keep holding the Volume Down button for about 10 seconds.
7. A notification will appear in iTunes that the program has found an iPhone in Recovery Mode.
Done - your iPhone 8, iPhone 8 Plus, iPhone X, iPhone XR, iPhone XS and iPhone XS Max have gone into DFU mode (black screen)! Now you can start restoring or updating it (detailed instructions).
If, after all the manipulations done, you didn’t see the notification in iTunes, it means that a mistake was made somewhere. Read the instructions again - now as carefully as possible - and try again.
How to Exit DFU Mode on iPhone 8, iPhone 8 Plus, iPhone X, iPhone XR, iPhone XS and iPhone XS Max
If you entered DFU not to restore the firmware of your iPhone, but for something else (for example, just to try how to enter the mode) and have already finished your business, you can exit it like this:
1. Press and release the Volume Up button.
2. Press and release the Volume Down button.
3. Press and hold the power button until the Apple logo appears on the screen.
According to yablyk
Any iPhone, iPad, or media iPod touch can be entered into DFU mode. To be honest, I myself have never entered my iPhone into DFU mode, they say that newbies do not succeed right away, to enter the device into this mode, you need to adapt, which we will do today. As a sample for experiments, we will take the Apple iPhone. A feature of entering DFU mode is a completely black screen, and there are no identification marks on the iPhone screen, if the transfer to DFU was accompanied by at least an inscription, as in the picture on the left, it would be a little clearer.
In addition to DFU, there is another mode called (recovery mode). What are these two modes for? They are mainly used to flash or restore the firmware of their iPhone. It also happens that the iPhone or iPad crashed and the iOS firmware does not start, in such cases they use the Recovery Mode and DFU modes. To begin with, they always try a softer mode - Recovery Mode, but if it does not help, then they already use the DFU mode.
Sometimes DFU is confused with Recovery Mode. So that you do not get confused, I will try to explain what is the difference between them:
- When you put your iPhone or iPad into Recovery Mode, appears on the device's screen. When entering into DFU, the screen of the device has a black display.
- It is not necessary to use iTunes to enter Recovery Mode. DFU mode without iTunes cannot be launched, I tried it myself.
- The Recovery Mode is launched using the iOS operating system, and the DFU mode bypasses the operating system, i.e. at the hardware level.
How to put iPhone in DFU mode
We will look at two combinations that can put our iPhone into DFU mode. You can use any more convenient. Before we begin, launch iTunes on your computer and connect your iPhone or other gadget to it using the supplied cable. Do not use USB adapters, plug the cable into the computer itself. After the iPhone is connected to a computer with iTunes running, we try to put the phone into DFU mode using one of the methods below:
Method 1. How to login to DFU
Putting iPhone into DFU mode. Method number 1
The easiest way to enter the iPhone into DFU is as follows - simultaneously hold down the Home button (Home) plus the power button (Power) and count up to 10. After 10 seconds of holding, release the Power button and continue to hold the Home button (Home).
Method 2. Second attempt to enter into DFU
Step by step start DFU mode in iPhone. Method number 2
This method is called more correct, but it is more difficult for beginners. and wait for the device to turn off completely. Now we hold down the Power button and count up to 3 seconds in the place with it, we hold down the Home button. Now, while holding Home + Power, count to 10 and release Power, but continue to hold the Home button.
iTunes during DFU mode startup
When completing the entry of the iPhone into DFU mode, it is useless to look at the phone screen, since it will simply be black, you need to look at the running iTunes program, which will detect a device running DFU mode and display the following message:
iTunes has detected an iPhone in recovery mode. You must restore this iPhone before using it with iTunes.
If you saw such a notification, and a single button appeared in iTunes - Restore iPhone, now look at the phone screen, if the screen is black, then it is in DFU mode. If something is not pressed correctly, then an image with the iTunes logo and a USB cable may appear, which means this is Recovery Mode.
How to exit iPhone in DFU mode
If, in the process of reading the instructions, you entered your working iPhone into DFU mode, you can exit the phone using the usual one - by holding the Home + Power buttons for 10 seconds. The phone will reboot and work normally. To exit the manually launched Recovery Mode, we used the same way to exit Home + Power for 10 seconds. With the cable connected, after holding Home and Power for 10 seconds, the phone may not start, then after that press the Power button and it will turn on.
Once, after an unsuccessful attempt to update the firmware, it got out and our iPhone fell into a permanent recovery mode, from which only helped to get out. Perhaps if the iPhone does not exit DFU with a reboot, then you can try programs like TinyUmbrella or iReb. So far, I have not come across a similar situation, but if I do, I will definitely tell you.
DFU mode on the iPhone (firmware updates) is constantly confused with Recovery Mode (recovery mode). In fact, the difference is huge, and it is as follows:
Recovery Mode is a softer mode compared to DFU; iPhone gets into Recovery Mode using the iOS operating system, and into DFU Mode bypassing it. DFU mode is only used when Recovery Mode refuses to help. DFU mode cannot be entered if the device is not connected to the iTunes media combiner. To enter Recovery Mode, it is not necessary to connect the gadget to a PC.
There are also external differences between the two specific regimes. The gadget in DFU MODE has a completely black screen, without the Apple logo; the gadget does not respond to pressing "Home" and "Power" separately. On the display of a smartphone in Recovery Mode, you can see the USB cable and the iTunes icon.
How to put iPhone 6 into DFU mode
DFU mode or Device Firmware Update is a special operating mode for mobile devices from Apple. In this operating mode, new firmware can be downloaded to the device, even if the device does not start or is not stable. DFU mode is used to restore the iPhone (as well as the iPad and other iOS mobile devices) to working capacity after update problems, JailBreak installation, or other software failures that render the iPhone inoperative.
The process of putting an iPhone into DFU mode is very similar to the process of entering recovery mode.
You can enter the iPhone into DFU mode using the buttons located on the device. For iPhone models up to version 6 inclusive, the algorithm of operations is somewhat different from entering the recovery mode of later versions.
- Connect the device to your PC with a USB cable
- Launch iTunes on your PC. Attention: the latest version of the program must be installed on your PC.
- Press and hold the Power and Home buttons at the same time for 10 seconds.
- Release the power button while keeping the home button pressed for 10 seconds. You should see a message on your computer screen in iTunes that your device is in recovery mode. The display of the phone itself will remain black.
- In iTunes, select the "Restore iPhone" option to reset your phone to factory settings. After that, all personal data will be erased, and the latest version of the system is installed on the iPhone.
- To exit recovery mode, press and hold the Power and Home buttons at the same time for 10 seconds, after which the device will turn off. The next time you turn it on (by pressing the power button), the device will boot up normally.
Good time! All you need to know about the DFU (Device Firmware Update) mode is that it allows you to put your iPhone or iPad into a state in which it is possible to completely restore the iOS system - after this operation, your gadget will be "like new". No, scratches and abrasions will not go anywhere, here you can’t get off with a simple firmware restore via DFU - you need something more serious. But inside the device will be clean.
Why is this even needed? Various software failures, proper jailbreak removal - all this can be cured and fixed only by a complete reinstallation of the system. Which, in turn, cannot be performed without entering this mode.
As you can see, DFU is a useful thing. And now is the time to learn how to use it all. One two Three. Go!
Putting any iPhone or iPad into DFU mode (when there is a mechanical Home button)
Perform the following steps in sequence:
- Launch iTunes and connect your phone or tablet to your computer.
- Turn off the device (it must still be connected to the PC).
- Hold down two buttons at the same time - Home (under the screen) and Power (located on the top edge of the device, except for the iPhone 6 and older versions - here it was moved to the right side).
- We wait 10 seconds and release the Power button while holding the Home key.
- We continue to hold the button for about 10 seconds.
- After a while, iTunes will inform you that the program has detected a device in recovery mode.
- Finally release the button :)
That's all, you can safely proceed to restore the firmware! The only thing, in order to avoid errors, use only original wires. Of course, non-certified ones also know how to charge (if they are), but they don’t do a very good job of updating the software.
By the way, when transferring to DFU, iOS devices do not show any signs. That is, the screen is completely black, nothing is written on it, there are no identification marks and no characteristic sounds are reproduced.
Only iTunes will inform you about the successful result of all manipulations. Here is a sign
How to put iPhone 7, iPhone 8 and iPhone X into DFU mode?
A small update of the article related to the release of the iPhone 7 (Plus), iPhone 8 (Plus) and iPhone X. As you know, the Home button in these models has ceased to be mechanical (in the "top ten" it was removed altogether) and is no longer pressed as before. How now to log in to DFU?
It's very simple, here's a quick guide:
- Launch iTunes and connect iPhone to computer.
- Turn off the gadget.
- On the phone, simultaneously press two buttons - power on and volume down (!!!).
- We wait 10 seconds and release the power button, but we continue to hold the “volume down”.
- After 5-10 seconds, iTunes will see the device in recovery mode.
- Release the volume down key.
Congratulations, your iPhone has entered DFU mode, you can start restoring the firmware.
How to enable DFU mode on iPhone XS, iPhone XS Max and iPhone XR?
The devices are new, but the Device Firmware Update mode is entered in the old way (just like in the G8s and iPhone X).
However, as Malakhov says, do not rush to switch.
For those who have problems with activating DFU mode using the method from the previous subheading, there is a slightly modified instruction.
I hope this will be a little easier.
So, we enter the iPhone XS, iPhone XS Max and iPhone XR in DFU:
- Turn on iTunes and connect your phone to the computer.
- Hold down the power button and wait.
- The Turn off slider appears. We wait and do nothing. Don't release the off button!
- After a while, the phone screen will turn black.
- Press and hold "Volume down" (continue to hold the power button!).
- After 5 seconds, release the power button (“Volume Down” is still holding!).
- After 5-10 seconds, iTunes will see the iPhone in DFU mode.
- Victory!
Let me remind you that this instruction is suitable for any iPhone starting from iPhone 8. We use it!
DFU mode for iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max. Instruction!
Hoping for something new? In vain. Nothing changed.
Activating DFU mode for the iPhone 11 (Pro Max) happens exactly the same as in all other iPhones (starting with the G8).
Therefore, if you are a happy owner of the iPhone 11 (Pro Max), then I can only envy you to transfer your smartphone to DFU mode, use the instructions in the previous subheading.
We enter the DFU mode without buttons, i.e. programmatically
Unfortunately, the previous methods may not always work, because they are based on the use of buttons - Home, Power and "volume down", but what if they do not work? Stay without DFU mode and, accordingly, without the ability to restore the software? Nothing like that - there is still a way out. We will need:
- Computer and sync wire.
- A file downloaded to your PC with the latest firmware for your device.
- redsn0w program. The download links are redsn0w_win_0.9.15b3 and redsn0w_mac_0.9.15b3 . The first is the version for Windows, the second for Mac OS.
Download and install redsn0w. In the window that opens, select Extras.
Following DFU IPSW and specify the pre-downloaded official firmware.
We wait a while and a modified software file appears on the desktop.
Now, if you specify this particular file when restoring iOS, then you do not need to hold down any Home or Power buttons, entering DFU mode will happen automatically.
How to get iPhone or iPad out of DFU mode
There is also a small nuance here. In most cases, you can get away with the usual reboot of the gadget. Well ... just hold the power button a little longer than usual.
Does not help? Then we perform a forced restart -. Naturally, you must first disconnect the device from the computer.
Here is such a short instruction turned out. However, there is nothing more to paint here - they pressed and held two buttons, released one and connected it to the computer. Everything!:)
P.S. But if I missed something or have any questions, write in the comments, I will supplement the article and I will answer with pleasure!
