DFU mode on iPhone (firmware updates) is constantly confused with Recovery Mode(recovery mode). In fact, the difference is huge, and it is as follows:
Recovery Mode – a softer mode compared to DFU; The iPhone gets into Recovery Mode using the iOS operating system, and into DFU Mode by bypassing it. DFU mode is applied only when Recovery Mode refuses to help. DFU mode cannot be accessed if the device is not connected to the iTunes media combiner. To enter Recovery Mode, it is not necessary to connect the gadget to the PC.
There are also external differences between the two specific modes. 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 USB cable and the iTunes icon.
How to put iPhone 6 into DFU mode
DFU or Device Firmware Update mode is a special operating mode mobile devices from Apple. In this operating mode, you can download new firmware to the device, even if the device does not start or is not stable. DFU mode is used to restore the functionality of the iPhone (as well as iPad and other mobile devices with iOS) after problems with the update, JailBreak installations or other software glitches that render the iPhone inoperable.
The process of entering the iPhone into DFU mode is very similar to the process of entering recovery mode
You can put your iPhone into DFU mode using the buttons located on the device's body. For iPhone models up to version 6 inclusive, the operation algorithm is slightly different from entering recovery mode for later versions.
- Connect the device to your PC using 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, leaving the Home button pressed for 10 seconds. A message should appear on your computer screen in iTunes indicating 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 this, all personal data will be erased, and the latest version of the system will be 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 on (by pressing the power button), the device will boot into normal mode.
Every owner of an Apple smartphone sooner or later faces the difficulty of loading the device normally, or even when it does not happen. The failure may occur after an unsuccessful system update, application installation, etc. Emergency System Recovery Mod - i.e. literally, recovery mode - allows you to fix any problems with the iPhone if their cause lies in a software glitch, and not in technical problems.
Recovery mode allows you to check and instantly fix any software problems iPhone phone.
The second purpose is to update iOS on iPhone to a new version. When you receive information that it is possible to update software for modified - the process also goes through this mode.
Before contacting a service center or a technician, try restarting or upgrading the system yourself. To do this, you will need the gadget itself, a PC (the type of operating system does not matter, Mac, Windows, Linux) and a USB cable to connect them.
Often the system itself launches Recovery Mod, a recovery mode, if iTunes detects any problems or damaged files when connecting to a computer. Then you just need to confirm the action, or select an upgrade, if it is available at that moment.
During the recovery process, the entire file system is checked for integrity, but all content, settings, passwords, etc. are reset to zero. During the upgrade, the settings are saved.
How do I sign in?
Important: any Apple portable multimedia device can be entered into this state using a standard template.
- We connect the proprietary cable to the computer, ignoring the connection to the gadget.
- Turn off the iPhone: at the moment when the cable enters the connector, the device should not show any signs of life.
- At the same time, we perform: holding down the Home button (the central round one, located under the display) and connecting the cable to the iPhone. Press until the device can display the iTunes inscription with the image of the logo and USB cable. Only then can you release the button. This layout on the screen means that you have entered recovery mode.
- Next, you should launch iTunes on your computer if it fails to display it automatically. In the program itself you need to choose one of two available options. which we talked about - firmware (version update) or recovery mode.
Important: you can use this mode only if your iPhone has official unlocked firmware, in other words, the system is Factory Unlocked.
How to get your phone out of Recovery Mod
It is important to know that often the system itself enters recovery mode, but sometimes you need to exit it.
There are two proven ways to remove your iPhone and one for an emergency:
- When you see an image of a cable and a logo on the screen, reboot the gadget by simultaneously pressing the Home and On/Off buttons (located at the top, on the edge of the case). You need to hold it for 10 to 15 seconds. The final step is to press the power button again.
- When the first method did not work, this means that the system automatically switched to another mode - Recovery Loop, and only special software like TinyUmbrella, iReb or RecBoot will help you get the gadget out of it.
- This is an extreme method, since it entails the loss of absolutely all data on the device, settings, files, passwords, etc. It involves restoring the system in iTunes when the operating system is overwritten. Attention! All data will be lost.
If none of the above methods helped to remove the device from Recovery Mod, you must urgently contact a professional repairman.
Good day! It’s no secret to everyone how to go into recovery mode on Apple devices. The fact is that on new devices such as Iphone 7, Iphone 7 plus, the " Home"(Home), has become touchscreen. Therefore, the method has changed a little. In this article we will describe in detail how to go into recovery mode on old and new apple devices. There are times when you need to change the software, or your device is frozen and on the splash screen, which shows a cord asking to connect to iTunes. In such cases, you need to put your device in " Recovery Mode"or as this mode was previously called" DFU Mode".

When you press two buttons, wait 10 seconds, you will hear that it has been found on your computer new driver, so after sound signal, released the power button, but continued to hold the home button. After this, the computer detected the device and installed the DFU mode driver.
On new Apple devices, starting with the Iphone 7, Iphone 7 plus, quite a few changes have occurred. Everyone already knows that these devices no longer have a 3.5 mm jack for connecting a headset to a smartphone. As I described above, the button Home Now it’s not mechanical, but sensory. Instead of regular USB, the developers installed " Lightning"- port, it is possible to connect headphones through it. The developers also forgot to mention how to enter the device into recovery mode, so users have to find a way on their own.
So that you don’t have to search for a long time, we will describe the method to you.
How to enter Recovery Mode (DFU) on iPhone 7 and iPhone 7 Plus?
- Go to the official Apple website and download the application ( iTunes) for your computer.
- Launch the application ( iTunes) on the computer.
- Turn off the device and wait 5 seconds until it turns off completely.
- Using lightning cable, connect your smartphone to the computer.
- As in previous versions, we need to press two buttons at the same time. First button Inclusion and second, Decrease volume .
- You must hold down two buttons until the Apple logo appears on the screen of your smartphone or tablet. The logo should appear and immediately go out, and after a while an image should appear that your connection via the lightning cable is active.
That's it, the iTunes program on your computer will show that your device is in recovery mode and you can continue to work with it.
As sad as it is, but even with the most careful handling There is still a chance that your favorite gadget will fall victim to a software glitch. According to statistics, most often problems arise in the software area of the device, and not in the hardware. This means that 90% of problems can be solved with flashing. IN Apple devices There are several recovery modes - each serves a specific purpose and it can be difficult for beginners to know which method to use. Today we will help you understand three ways iPhone flashing: Update, Recovery Mode and DFU mode. The information presented in this article is quite sufficient to avoid contacting service center and spending unnecessary funds.
Update– official update method iOS firmware from old to new. This method is used solely to keep your iPhone, iPad or iPod up to date in terms of software. The update occurs while preserving all individual data (installed applications, SMS, contacts, notes and other content). The advantages of this method include relative efficiency and the ability to update using Wi-Fi.
Recovery– return your i-gadget to factory settings. During this process, all personal data is deleted. Before choosing this option, you must save the necessary information to iCloud or make a backup using iTunes. By the way, Apple specialists recommend updating the firmware using the recovery procedure, since installing new firmware on a “clean” system always goes smoother and guarantees the absence of residual files and system garbage. For readers from Russia, we strongly recommend that you first download the next firmware version to your PC and only then install it. This measure will avoid disappointment and long waits if Apple's servers are overloaded.
There are several options for restoring stable operation of the iOS mobile system: DFU And Recovery Mode .
Before moving on to a detailed consideration of both modes, it is necessary to understand the mechanics of interaction with the device. Transitions to recovery modes are directly related to constant manipulation of the smartphone’s power and home buttons. You must be able to hold these buttons at the same time and leave one of them pressed for a precisely defined time.
Recovery Mode– basic recovery mode, which is activated when the device and iTunes work together. The tuna signals the start of recovery with the message: “device in recovery/stabilization mode,” and a corresponding image appears on the iPhone.
Instructions for entering the gadget into Recovery mode:
1. Turn off your iPhone (press the “On/Off” button and confirm the command by swiping on the smartphone screen).
2 . Press and hold the Home/Touch ID button with one finger and simultaneously connect the gadget to your desktop computer.
3. An image of the planet Earth/disk and wire should appear on the iPhone, and a notification on the computer that the smartphone has entered recovery mode.
Exiting Recovery mode:
1. Turn off the iPhone again by holding down the button on the top end of the smartphone.
2. After the screen becomes dark, disconnect the smartphone from the USB cable.
3. Press the Home button again and press the Power button once.
4. If everything is done correctly, the device should boot. After that, release the Home button.
Device Firmware Upgrade– deep device recovery mode. It is considered an emergency and is used to solve serious problems and static errors that are responsible for the operation of the device. In order to understand that DFU mode is activated, you need to monitor iTunes signals, since the smartphone display will be black.
Activating DFU mode:
1. Quit iTunes if it is running.
2. Using a USB cable, connect the smartphone to the computer.
3. Turn off the iPhone and press the power button again for about 5 seconds.
4. While continuing to hold the Power button, press the Home button and hold it strictly for 10 seconds.
5. Then release Power, continuing to hold the Home button for another 10 seconds.
6. The smartphone screen should remain pristine black. If it appears White screen, apple logo and other other “signs of life”, then you need to return to step 1 and repeat all the steps again.
7. Don't be scared and play the guessing game. If everything is done correctly, the computer will display a notification: “A new device has been detected.”
Instructions for iPhone output from DFU mode:
1. We connect the smartphone to the computer.
2. Click Home buttons+ Power to 10.
3. Release both buttons.
4. Press the Power button and wait for the iPhone to boot.
5. Again we create a tandem of the Power and Home buttons. We wait until the snow-white Apple logo appears on the screen.
UPD: All specified modes are valid for all portable devices from Apple: iPhone, iPad and iPod.

You need to enter the device into this mode if the user of an Apple gadget encounters problems when updating the operating system or when flashing a jailbroken smartphone. In addition, by transferring the iPhone to DFU-mode and returning it to normal, you can correct a number of system errors, which can lead to incorrect operation devices.
DFU mode on iPhone (otherwise - firmware updates) is constantly confused with Recovery Mode(recovery mode). In fact, the difference is huge, and it is as follows:
- Recovery Mode– softer mode compared to DFU; V Recovery Mode The iPhone is accessed using the iOS operating system, and in DFU Mode- walking around her. Mode DFU only applies when Recovery Mode refuses to help.
- To mode DFU impossible to get in if the device is not connected to the media harvester iTunes. To enter in Recovery Mode It is not at all necessary to connect the gadget to a PC.
There are also external differences between the two specific modes. At the gadget in DFU MODE completely black screen, no Apple logo; The gadget does not respond to pressing " Home" And " Power" separately. On, located in Recovery Mode, the USB cable and icon are visible iTunes.
How to enter iPhone into DFU MODE?
There are two ways to enter an Apple gadget into DFU mode - both are applicable for any of Apple devices. The first one is:

The gadget itself will not let the user know that he has switched to DFU MODE.
The second method of switching to firmware update mode is considered more correct, however, it is often not suitable for beginners. The initial step is also to connect the smartphone to iTunes– then you need to proceed like this:
Step 1. Turn off the device - wait until its screen goes completely dark.
Step 2. Hold down the " Power", count down 3 seconds, then press additional " Home" This is where the main difficulty lies: you need to perform these operations in such a way that the iPhone does not turn on in normal mode.
Step 3. Count down 10 seconds after pressing " Home" and release " Power». « Home"Don't let go.
Step 4. IN iTunes a message will appear - in the window, click “ OK».
Is it possible to put an iPhone into DFU mode if the physical buttons don't work?
To get into mode DFU without using physical buttons, you will have to transform the existing original firmware to a custom one using a simple utility called redsnOw. You can download this program for Windows and OS X.
Before you start using the utility, you need to download HDD PC suitable firmware. Then you should do this:
Step 1. Run redsnOw and follow the path " Extras» — « Even More» — « DFU IPSW».
Step 2. In the window " DFU-mode IPSW workaround» click « OK».
Step 3. Through File Browser find the firmware that you downloaded earlier (file format ipsw).
The utility will begin creating custom firmware - the progress of this process is reflected in the status bar.
Once the process is completed, a message will appear indicating that the IPSW file has been successfully created. In the message you will see the path along which you can get to the firmware.
You can distinguish DFU firmware from the original one by its name: custom firmware always has the prefix “ENTER_DFU_”.
Step 3. Connect your iPhone to your computer and launch the iTunes program, go to the gadget control menu by clicking on the icon with the image of a smartphone.
Step 4. On your Windows PC keyboard, press “ Shift” (on Mac - “ Option") and click on the button " Restore iPhone..."
Step 5. Select custom firmware in the window that appears.
Step 6. iTunes will warn you that iPhone recovery leads to data deletion - click " Restore».
From this moment on, the firmware will begin downloading to the smartphone via DFU Mode.
How to get iPhone out of DFU mode?
It's quite easy to restore your iPhone back to normal:
Step 1. Disconnect the gadget from the PC.
Step 2. Press the buttons " Home" And " Power"at the same time and hold it for 10 seconds. All you have to do is wait until the smartphone exits DFU mode, reboots and starts working in standard mode.
If the gadget is connected by cable to the computer, then after a 10-second wait you need to release the buttons and hold down “ Power» for another 3 seconds (as during normal switching on).
Conclusion
Putting a smartphone into DFU mode is a rather dangerous procedure; if the user makes a mistake, the iPhone may end up in " eternal apple" or in " recovery loop“It’s not easy to get out of these modes. To return your smartphone to normal operation, you will have to use additional software, like iReb or Tiny Umbrella, or turn to specialists for paid help (if the time to master special programs No).
It happens that due to total failures in the system iOS iPhone freezes and does not show any signs of life, representing a real “brick”. But don't worry right away. Perhaps not everything is as bad as it seems. There is a special DFU mode, which in some cases helps to correct the situation and fully restore the functionality of your device. Actually, this mode and its features will be discussed in this guide.
From the article you will learn
What is it and why does a simple user need it?
DFU mode stands for (Device Firmware Update). Translated into Russian as “device firmware update.” Only used in Apple products, in iPad and iPhone, and is a special emergency mode, and therefore is recognized only by iTunes software when connecting the smartphone to a PC.
Most likely, many have heard about Recovery Mode, but DFU differs from it in that it does not show any signs when activated. That is, the operating system does not load on the iPhone, there are no icons or icons, not even vibration. The phone seems to be dead! At the same time, pressing the Home and Power keys also does not show any signs.
It is mainly used to restore iPhones, flash firmware, and return the phone to its normal state if, for example, it has stopped showing any signs at all. Very often it corrects system failures, after which it boots in normal mode.
As a rule, this is the last stage and the hope for self-recovery of the device. Many services also resort to this method when resuscitating iPhones of different generations.
Mode activation
On this moment there are 2 different ways to put the iPhone into DFU mode, and they depend on the generation of smartphones. Everything that was released before 2016, and this is up to and including the iPhone 6, works according to the standard version. The new generation - iPhone 7 and higher - will be put into recovery mode in a slightly different way. Of course we'll look at both.
Apple phones up to and including iPhone 6
On all models up to and including the sixth iPhone, the procedure for entering recovery mode does not differ between versions.
You need to do the following:
- Open iTunes on your computer, since the recovery procedure is carried out through this software. You can download it from the official Apple website for free.
- Connect your smartphone to your computer using a special USB cable.
- Turn off your smartphone if it is not turned off. Now press two buttons at once - Home and Power. Keep them pressed for about 10 seconds.
- Now release the Power button, but don't release the Home button. You need to wait until iTunes app recognizes a new device on the PC. Usually you have to wait about 10-30 seconds.
- Once the system recognizes the new device and displays a recovery message, release the keys and proceed to the recovery procedure.
iPhone 7 and later versions
If you are the owner of an iPhone 7, 7 Plus or newer models (iPhone 8 and later), then in order to enter your gadget into DFU mode, you need to follow slightly different steps. The whole point is that there is no longer a physical Home key. Apple developers abandoned the mechanical button in the 7 series and replaced it with a touch button with a special tactile response mechanism.
And so, we perform the following actions:
- Launch iTunes on your computer (be sure to update to latest version, otherwise failures and errors are possible when working with devices of new generations).
- Connect to iPhone computer using a USB cable. Turn off your smartphone. If it is already turned off, go to item #3 in this list.
- Press the Power button and hold it down for about 3 seconds.
- Hold down Power and press the key "Volume Down" and keep both keys pressed for about 10 seconds.
- Then release the Power button, but continue to hold "Volume key" approximately 5 seconds.
- If everything was done correctly, iTunes will automatically detect the new device and display a notification on the screen that it has entered recovery mode.
How can I tell if my smartphone has not entered DFU mode?
If you didn't succeed the first time, and you try again and again, but the smartphone still does not go into recovery mode, then most likely you are simply missing some important details.
The reasons described below will help determine whether the smartphone has switched to DFU mode or not.
And so, the iPhone will not go into DFU mode if you observe the following symptoms:
- The Apple logo lights up on the screen.
- The screen on the iPhone is not black, but flickers or lights up a little.
- iTunes can't detect a new device on your computer.
And now ways to eliminate them:
- If the Apple logo lights up on the screen, most likely the iPhone is trying to turn on in Recovery Mode. This indicates that the user is not following the keystroke sequence and timeout correctly. Try again, carefully, performing all the steps point by point.
- As in the first case, the smartphone tries to connect in Recovery Mode or simply turns on as disk drive. Try the entire procedure again.
- Be sure to connect to the Internet so that Windows will automatically search for drivers if they are not installed on your device. Another important tip is to change the USB port and try to insert the device not into the front USB, but at the back of the computer. Often, low-power PCs simply do not have enough resources for the USB port to work correctly.
Removing the phone from mode
If you have already connected the gadget to the computer in a special “recovery mode”, but suddenly decide to remove it, under no circumstances try to simply pull out the USB cable and disconnect the iPhone, otherwise you may end up with a “brick”. Not a fact, but there are cases.
To painlessly exit the DFU state, you need to do a so-called “cold restart” of the device.
To do this, simultaneously press the “Home” and “Power” keys (for versions up to and including iPhone 6) or the “Power” and “Power” keys. "Volume Down Keys"(for iPhone 7 and later), hold them for about 10 seconds and release. The smartphone will automatically begin loading and launching the operating system as usual. Then, after turning it on, disconnect the USB cable and you can work with the iPhone.
Attention! Sometimes, when the USB cable is turned on, after the operations have been performed, the phone does not start if the user suddenly decides to exit recovery mode. In this case, after holding the keys, release them and quickly press “Power” again, and then the phone will turn on 100%. But this is provided that it is working for you. If your iPhone hasn't worked before, don't expect magic!
What should I do if I need to log into DFU but the buttons don’t work?
If the buttons on your device do not work, then you can use a separate utility that does not require physical key presses. Let's say that we decide to restore the phone to a stable version and return it to working condition. To do this you will need to perform the following steps:
- Download the latest working firmware for your device;
- Download the redsn0w program to your computer. Download links are provided below: for Windows (), for Mac OS ();
- Install the redsh0w program on your computer, connect the device to the computer using a USB cable and open the program;
- In the dialog box that opens, find the “Extras” tab and click on it;
- Next, click on the “Even More” tab;
- After that, click the “DFU IPSW” tab and specify the path to the downloaded firmware and open it;
- The program automatically converts new file firmware, which will already have built-in DFU. Once the operation is complete, in the same folder as original file, a DFU firmware with the same name will be created, only the prefix ENTER_DFU will be added;
- Now open iTunes. If the phone is not detected, simply remove the USB cable and insert it again, without pressing any buttons. But keep in mind that the iPhone must be turned on;
- The program detects a new device. Go to iTunes, select the iPhone icon in the list and click on it;
- Next, hold down the “Shift” key and click on the tab "Restore iPhone". If you carry out the entire process with Mac OS, then instead of “Shift” press “Alt”;
- The system will ask you to select the firmware file. Specify the path to our modified file with DFU firmware and confirm the operation;
- iTunes will notify you that all data will be deleted from memory. You agree to this notice and confirm the operation. The recovery process will begin;
- Your smartphone will reboot, the cable with the iTunes icon will blink on it and the recovery process will begin, and then the screen will simply go dark;
- After several reboots, the system will notify you that the iPhone could not be restored. That's it, the procedure is completed. We didn't need the iPhone to be restored. Thus, the program put our phone into DFU mode without physically pressing the keys;
- Now go to iTunes again, select recovery and specify the original firmware, wait until the phone is restored, and enjoy its correct and stable operation.
As you can see, this mode is very useful and in many cases it is what allows you to revive the iPhone and restore it to working condition. Mainly used after unsuccessful firmware. But in order to resort to such procedures less often, try to download only stable versions of iOS that have already been officially released for your iPhone model. Just keep in mind that all data from your phone is erased during recovery.
It is important to know! Many sites advise doing this backups system so that in case of any problems, you can revive the phone and “feed” a copy to it, thus restoring everything custom settings and programs. But you will take into account the fact that if at the time of creating the copy there were problems in the system, for example, after updating to iOS version, then the problems will remain after the backup. Therefore, make copies before updating, and only then test, update and otherwise use your phone.
No matter how reliable the iPhone 6 is, it is not immune to various types of failures. In some cases, the phone stops responding to any user actions: the screen does not light up, the buttons are inactive. In order to get it out of this state, the developers provided the dfu mode. The abbreviation dfu stands for: device firmware update, that is, updating device firmware.
This mode is effective means, which helps to successfully remove the iPhone from many emergency conditions. They occur especially often after iOS updates when the user tries to implement them on their device.
When activated, dfu acts as a bootloader, since operating system, for one reason or another, does not do this. In the process of restoration in this mode, happens complete removal and reinstalling the system. All previous settings and personal data are erased, and the latest current version of iOS is downloaded to the phone. After personal information can be restored, provided that you have backup copies of it.
How to initiate dfu
This is very important and required function, let's take a closer look at how to enter an iPhone into dfu mode.
First, connect the switched-off device with a USB cable (preferably a branded one) to the authorized computer with which it was previously paired (since you will not be able to enter confirmation from a non-working iPhone to connect to a new device).
Secondly, simultaneously press and hold the “Home” and “Power” buttons pressed for ten seconds.
Thirdly, release the “Power” key and hold down the “Home” key until a characteristic iTunes notification appears on the computer monitor that the device is under dfu mode. (It is recommended to update iTunes to the latest version before this to avoid errors)
At the same time, the phone itself does not reflect the successful completion of this mode. His screen is still disabled and cannot display any system messages. The computer will carry out all further processes itself. It must be connected to the Internet, as you will have to download the latest version of iOS from the Internet. This may take more than one hour until all file system partitions are successfully installed on the phone.
If you cannot switch your iPhone to dfu mode the first time, try repeating the entire procedure a little later using the original USB cable.
As you can see, putting your iPhone into DFU mode is not at all difficult. Let's now find out how to get him out of it.
How to disable already running recovery mode on iPhone 6
If, after starting dfu mode, you change your mind about restoring the system so as not to lose all existing data, then you can easily remove your iPhone from it. To do this, it is enough to perform a regular reboot, i.e. Press the Power and Home keys and hold for ten seconds. After turning on the power, the phone will start loading into normal mode (provided that it was operational before). It makes sense, as a training, to carry out this process before problems arise. So that later you can be prepared and not make mistakes.
In conclusion, we will say that you should not neglect the use of this mode. It will help restore your phone in cases of system failures, or when the current update has gone wrong, and also if you have forgotten your password. If you have a backup, you will copy all your data again, and your iPhone 6 will work like a Swiss watch.
