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 with your iPhone.

The second purpose is to update iOS on iPhone to a new version. When you receive information that it is possible to update the software to a modified one, 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 an 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 remove the device from Recovery Mod, you must urgently contact a professional repairman.

It’s sad, but even with the most careful handling, there is still a chance that your beloved 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. Apple devices have several recovery modes - each serves a specific purpose, and it can be difficult for newbies to know which method to use. Today we will help you understand three ways to flash an iPhone: update, Recovery Mode and DFU mode. The information presented in this article is quite enough to avoid contacting a service center and spending unnecessary money.

Update– the official way to update 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 a white screen, an Apple logo and other other “signs of life” appear, 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 removing iPhone from DFU mode:

1. We connect the smartphone to the computer.

2. Press the Home + Power buttons at 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.

Beginning iPhone and iPad users often encounter difficulties in the process of flashing the iPhone and updating iOS to the latest version. This is especially true for owners of jailbroken iPhones, whose flashing from iOS sometimes causes iTunes errors. In this manual we will introduce you, dear readers, to what DFU mode iPhone, what is it for, how to enter DFU mode and what to do if the iPhone is “stuck” in this mode and will not boot.

What is DFU mode on iPhone?

DFU mode (Device Firmware Update) is a device firmware update mode. Refers to emergency modes and is recognized by iTunes when connecting an iPhone or iPad to a computer using a USB cable as a recovery mode.

It differs from Recovery Mode in that in this mode the device does not show visible signs of life (the control buttons do not work, there is no image on the display).

In this mode, the iDevice operates without loading the operating system shell, so no picture is visible on the iPhone display and the device does not react in any way to pressing the “Power” and “Home” buttons separately.

Why do you need DFU mode in iPhone, for example?

DFU mode is used to restore or update iPhone firmware (aka iOS) in cases where standard iTunes tools cannot perform the required operation.

In some cases, DFU mode can fix a system crash in your iPhone, allowing the device to reboot normally.

How to put iPhone into DFU mode?

The DFU mode in the iPhone 5 and iPhone 4, and in any other mobile device from Apple (iPhone, iPod Touch and iPad) is launched exactly the same:

Connect your iDevice to your computer (it can be a Windows PC or Mac).
or press and hold the “ Home" And " Power"for 10 seconds.
After 10 seconds release the "Power" button, while keep holding the Home button pressed.
Hold the Home button until the computer recognizes the iPhone in DFU mode.

Let us remind you that it will not be possible to recognize the DFU mode in an iPhone by external signs; in this mode, it does not respond to single button presses and the display does not work.

It’s good when the iPhone is working and all the controls work, but it also happens that one of the “Home”, “Power” buttons or both do not work at once, what should I do? In this case, our instructions “or Power, or both at once” will be useful to you.

How to get iPhone/iPad out of DFU mode?

To do this, simultaneously press and hold down the “Power” and “Home” buttons for about 10 seconds. Then briefly press the iPhone's power button (aka Power). A corporate logo should appear on the device’s screen, which is evidence that the device boots in normal mode.

In conclusion

DFU mode in an iPhone or any other device running iOS is extremely useful; it allows you to restore the device to its working state in the event of any system failure, restore the firmware or update iOS to the latest version, bypassing the normal mode. If your device refuses to boot in normal mode or when restoring/updating the firmware from normal mode using iTunes, a system error occurs, just enter it into DFU mode and perform a firmware recovery or update in this mode.

Apple smartphones work very stably and rarely need firmware recovery. However, sometimes it becomes necessary to return the iPhone to its factory state in order to get rid of glitches after an unsuccessful software update or system failure.

📍Thank you re:Store for useful information. 👌

DFU mode ( Device Firmware Update) is a low-level iPhone firmware update mode. When you turn it on, the smartphone will be recognized by the computer to restore iOS. The iPhone itself will not load the system’s graphical shell and respond to button presses.

Very often, DFU mode is confused with Recovery mode. Outwardly, they are easy to distinguish; in DFU mode there are no symbols on the iPhone screen, but in recovery mode you will see an indicator for connecting to a computer.

Recovery Mode is a software recovery mode for iOS. The data remains in place, and system files are restored from the original firmware or backup.

DFU mode is an iOS recovery in bootloader mode, in which all files are erased and overwritten with data from the original firmware.

Conventionally, Recovery Mode can be compared to loading a Time Machine backup, and DFU mode can be compared to a complete reinstallation of the operating system.

How to Enter DFU Mode on iPhone with a Physical Home Button

All older Apple smartphone models up to and including the iPhone 6s and iPhone SE have a physical Home button. On them, logging into DFU is carried out as follows:

2. Turn off the iPhone.

4. Press and hold the Home button while continuing to press the Power button.

5. After 10 seconds, release the power button and continue to hold the Home button for another 5 seconds.

To exit From DFU mode you need to hold down the Home and Power buttons for 10 seconds.

How to enter DFU mode on iPhone with touch Home button

In smartphones with moisture protection, Cupertino has abandoned the physical button on the front edge of the smartphone. It was replaced by a touch key. The procedure for switching to DFU mode is slightly different:

2. Turn off the iPhone.

3. When the screen goes dark, press the power button for 3 seconds.

4. Press and hold the volume down button while continuing to press the power button.

5. After 10 seconds, release the power button and continue to hold the volume down button for another 5 seconds.

A black screen on your smartphone will indicate that you have entered DFU. An apple on the screen signals the start of iOS loading; you will have to repeat the procedure again.

To exit From DFU mode you need to hold down the Volume Down and Power buttons for 10 seconds.

As you can see, the process of entering and exiting this mode differs only in the use of the volume key instead of the Home button.

Here is a video tutorial for models with a physical and virtual Home button.

2. Alternately press the volume up button, then the volume down button and hold down the power button.

3. As soon as the smartphone screen goes dark, press the volume down button and continue to hold the power button for 5 seconds.

4. Release the power button and continue holding the volume down button for another 15 seconds.

If you see the Apple logo, it means iOS has started downloading and you did something wrong. I'll have to try again.

To exit From the mode you need to alternately press the volume up button, the volume down button and hold down the power button. You can release the button after an apple appears on the screen.

For clarity, here is a video instruction for iPhone X/XS/XR/11/11 Pro.

Updating iOS devices is very simple - just press one button in the settings, enter the password and the device will be updated to the latest version. However, things do not always go smoothly, and glitches occur when updating the firmware. Problems can especially often arise among owners of jailbroken devices, those who installed Jailbreak. For all cases when the iPhone or iPad behaves incorrectly, you can restore the device through DFU mode.

DFU mode or Device Firmware Update is a clean installation of the iOS operating system on the iPhone. It is activated using a computer. Therefore, even if a system crash disrupts the screen and you cannot interact with the device normally, there will be no problems during recovery.

After restoring your iPhone via DFU, the device will be updated to the latest available version of iOS, and all data from the device will be deleted. Therefore, it is very important that you have iCloud backup enabled on your device. Then you can easily restore your data.

Before using DFU

DFU mode is a powerful tool for returning iPhone to working condition in case of system errors. However, it is not always necessary. Before you install the system from scratch and lose all your data (if there is no backup), try the following methods.

Sometimes it is enough to force a reboot of the device. On iPhone versions 6S and lower, rebooting is carried out by simultaneously pressing and holding the Home button and the power button. On iPhone 7 – Home button and Volume down button. On iPhone 8, X, XS – press the volume up button once, press the volume down button once and then hold down the power button. Hold until an apple appears on the screen.

If restarting your device doesn't help, try recovery mode. This way you will not lose personal data (even if there is no backup) and you will be able to restore the device. Here everything is done exactly the same as when rebooting the device. However, the iPhone must be connected to the computer via Lightning.

Important point. Before connecting the device to the computer, iTunes must be closed. You need to launch it after connecting.

How to put iPhone into DFU mode

In order to put your iPhone into DFU mode, iTunes must be installed on your computer. If you are using a Mac, it is already pre-installed, but if you are using Windows, you will need to download and install it yourself.

Turn off your iPhone, connect it to your computer using a cable, and launch iTunes.
After that, press and hold the power button and the “Home” button on the device for 10 seconds.
Then release the power button, but Home should remain pressed.
Wait another 15 seconds.

If everything is successful, a message should appear on the computer screen: iPhone detected in recovery mode. At the same time, the iPhone will not show any signs.

To enter DFU mode on the iPhone X, XS and XS Max or new iPads, you need to follow all the same steps, only replace the Home button with the volume down key.

There will be a card with your device on the computer screen. Here you just need to click the “Restore iPhone” button to start the process of installing the latest version of the system.

How to exit DFU mode

To wake your iPhone from DFU mode, you must hold the Home button and the power button for 10 seconds (on devices without a Home button, the volume down button). Then press the power button once (the Home button should no longer be pressed). The Apple logo will appear on the device screen, indicating that the device is starting to start.
