What is pwned dfu. Possible ways to put iPhone into DFU mode

If you have had any problems with the software on your iPad, or needed to erase all information from the device, you know what updating and recovery are.

In the same case, if suddenly you have not encountered either one or the other, and also do not know what DFU mode is (iPad or iPhone - there is no difference), this article will be useful to you. In it we will look at how to work with this mode and what it is. Don’t be intimidated by the terminology and, at first glance, complex abbreviations - everything is very easy and simple. A person who has minimal experience with a computer and tablet can handle this.

General overview

First, let’s clarify what this DFU mode is. iPad, as you know, runs on the iOS operating system. When you work with it, you use touch responsive. This is exactly how the device control procedure is carried out - the graphical interface accepts commands sent by the user, after which the OS processes them and reacts properly.

If you have this knowledge, you will not need to contact a service center with a request to fix a software error. This can be done even at home. This, obviously, was Apple's goal - to make a product so simple and convenient that even a non-specialist at home could fix a system problem with it. As we can see, they succeeded.

iPhone restoration is a standard operation to return an Apple smartphone to a working state after various failures. Unsuccessful firmware, incorrectly executed jailbreak, incorrect iOS update - if you know how to restore an iPhone, you can fix almost any problems that arise during the operation of this device.

Recovery procedure

To restore your iPhone, you need to enter Recovery Mode. It's easy to do:

When the iPhone is ready for the rollback and error correction procedure, click the “Restore” button.

iTunes will independently find the current firmware version and install it on the smartphone, returning it to the state in which it was immediately after purchase.

Working in DFU mode

If iPhone recovery does not work in Recovery Mode, then you need to enter the device into DFU mode. This mode is used when there are software errors - for example, when the iPhone does not turn on. DFU mode works at the hardware level, so it helps to reset all settings even in the most difficult cases. To enter DFU mode:

  1. Connect your device to your computer.
  2. Press and hold Power and Home for 10 seconds.
  3. After counting to 10, release Power while continuing to hold the Home button.

It's difficult to enter DFU mode the first time because nothing changes on the screen. If the recovery mode detects itself as an iTunes icon, then the phone does not seem to turn on in DFU. Therefore, you need to look at the computer screen where iTunes is running. As soon as the iPhone enters DFU mode, a notification will appear in iTunes informing you that the program has detected the device in recovery mode, and you need to reset all settings and content to continue working with your smartphone.

If you need to install another firmware, hold down Shift and click “Restore”. An explorer will appear through which you need to specify the path to the previously downloaded firmware.

Recovery without a computer

If you don’t have your computer at hand, it won’t turn on, or you can’t connect your iPhone to it, then try resetting all settings through the device settings. As a result of this operation, you will receive a clean smartphone without settings and user information, so be sure to make a backup before resetting. If the smartphone turns on normally:

It is not necessary to delete user files. If the iPhone turns on, then you can eliminate problems with its operation by simply resetting the settings. In this case, the user’s personal data will remain intact.

Recovery after reset

If you need to restore your iPhone after resetting all settings and deleting content, you won’t be able to do this without a backup copy. The presence of a backup file with information stored in the device’s memory is the main point that needs to be checked before performing a reset. After restoring the iPhone to its factory state, all personal data of the user is erased from it.

Creating a backup before resetting:


After the reset, the iPhone will be like new: no content or settings will remain on it. To get all the information back, you need to connect the device to your computer and restore from the backup via iTunes. Choose the most recent backup, as it stores the most current information.

You can also restore all settings after a reset via iCloud, provided that you stored backups on the cloud. In this case, when setting up your iPhone, you need to select the “Restore a copy from iCloud” option and specify a suitable backup.

Problems during recovery

If after a normal recovery the phone does not turn on, then it makes sense to put it in DFU mode and try restoring it through iTunes again. This time you should not trust iTunes: download the official firmware and select it in the Explorer window by holding Shift and clicking on the “Restore” button .

Sometimes the TinyUmbrella utility helps solve the problem that the smartphone does not turn on after resetting the settings via iTunes. This program has an “Exit Recovery” button. If the iPhone does not turn on after recovery, you need to select it in the TinyUmbrella window and click “Exit Recovery”.

Not long ago, new smartphone models from Apple - iPhone X, iPhone 8 and 8 Plus - entered the global mobile device market. It would seem that only iPhone 10 has radically different controls from previous models, but no... Eights have also undergone changes. Everyone who purchased these devices will have to relearn how to press buttons, because if you don’t know the new combinations, you won’t be able to do a hard restart, enter recovery mode and DFU mode.

No matter what you do, the key combinations that worked on previous models will not work at all on the iPhone X, 8 and 8 Plus. In this article we will tell you how to force a reboot, activate recovery mode and DFU mode.

Before moving on to the instructions, we will repeat the names of the iPhone X keys. Nowadays, the power and lock key of the device is called the “Side Button”, or “Side Button”. In the past it was called "Power". The Volume UP and Volume DOWN keys have not changed their names. The “HOME” button has also undergone changes - it is simply NOT present (but only in the iPhone 10). The iPhone 8 and 8 Plus still have the Home button. Despite this, the key combinations are the same for all of them.

Now let's get down to business.

How to restart iPhone X/8/8 Plus?

If suddenly your smartphone freezes, glitches, or does not turn on at all, you need to do a forced reboot. Below are step-by-step instructions to help you reboot.

  1. Briefly press the Volume Up key. After pressing, you must immediately release the button.
  2. Briefly press the Volume Down key. After pressing, you must immediately release the button.
  3. Press and hold the Power Button (Side Button). Hold until the Apple logo appears - an apple.

Well, now you know how to do a hard reboot.

Recovery Mode on iPhone X/8/8 Plus

Now we will figure out how to enable recovery mode. We follow the instructions:


DFU Mode on iPhone X/8/8 Plus

Now it's time to tell you about the DFU (Device Firmware Update) mode. If suddenly none of the above helped, the only hope left is for this regime. There is nothing more you can do on your own. Then only to the official service center.

This mode is for installing the operating system “from scratch”, so to speak “From under the BIOS”. Based on this, everything that was previously stored on the phone will be deleted permanently.

The “Device Firmware Update” mode will help in cases where the iPhone gets stuck at the boot stage (cyclic reboot), or in cases where the phone sometimes displays a blue or red “screen of death”.

Before you take action, ATTENTIVELY read what is written below to imagine and understand everything fully, how and what should be done. Let's get started.


That's all. In truth, DFU mode on the iPhone X and 8 is activated exactly the same as on the iPhone 7. Reboot and recovery mode are new.

Over time, we will all get used to the new combinations, and we will not have problems with this.

P.S. I hope this information was useful to you!

Recently, the Android and iOS operating systems are rapidly gaining popularity among many users, providing a rich selection of various options and pre-installed applications, available programs in Google Play and Apple Store services. But, as a rule, there are also people who like to experiment, try different modes, firmware, delve into the phone’s system files, install various tweaks and much more. In most cases, for beginners, the iPhone simply stops working and does not turn on.

If you are one of those people who cannot bring their device back to life using standard methods, without spending additional money on service specialists, we recommend reading this material. In it we will tell you about the DFU mode and how to use its functions to bring your gadget back to life.

DFU mode in Apple devices

In general, what is DFU mode, you ask? It stands for Device Firmware Update. In short, this is a separate mode of the phone that allows you to “roll back” or restore the device to the normal, stable firmware of the iOS operating system. And if the user is unable to restore functionality using standard methods, then DFU mode is one of the last resort methods.

Only you must understand that DFU will completely delete all data from your device. Here you have to choose - either the performance of the phone, or the safety of the data, which, unfortunately, you may never view!

  • If your smartphone does not turn on in the standard way.
  • It is impossible to restore the firmware.
  • The phone stops charging and the problem is not with the charger or battery.

The first way to put your iPhone into dfu mode

Before you begin, carefully read these instructions and follow all steps clearly, step by step, as described in the material.

And so, to put your iPhone into this mode, you will need to follow these steps:

The second way to start an iPhone in DFU mode

If for some reason you are unable to enter this mode using the method described above, read this subsection. We have posted a simplified version especially for you. And so, you need:

  1. Connect the device to the charger and hold it for at least 5 minutes with the power connected.
  2. Disconnect the smartphone from the charger and connect it to a personal computer using a USB cable.
  3. Press the POWER key on your iPhone and count to 3 seconds.
  4. Without releasing the POWER key, press HOME and count up to 10 seconds.
  5. As soon as you count to 10 seconds, release POWER and hold HOME.
  6. As soon as the device enters DFU mode, an additional tab will appear on the iTunes program screen for restoring the firmware.

As you can see, the recovery principle is not complicated, but the accuracy of the step-by-step algorithms and time calculation are important here. We recommend that you time the seconds on another phone or a stopwatch, for example, built into Windows programs.

Using this method, you can roll back all changes at any time and restore the functionality of the iOS operating system. But to prevent such situations from arising, be sure to create backup copies of your iPhone, saving them in the iCloud cloud service or on a personal computer, removable storage device, using the iTunes program.

How do I know if my iPhone is in this mode?

Another relevant and related question that users often ask on the Internet is how to find out that my iPhone is in DFU mode? In fact, you won’t be able to tell by its appearance on the screen, because the device simply won’t turn on (black screen and that’s it).

But, you can connect the device to a computer with iTunes installed. If you have DFU mode activated, the system will automatically display a notification window in this format.

We take the device out of this mode

And so, let’s say that you have switched to this mode, but you are not going to restore your phone to the old firmware. What to do in this case?

Do not try to simply disconnect the device from the computer! You must exit DFU mode first.

This is done like this:

  1. Disconnect the iPhone from the computer and simultaneously hold down the POWER and HOME keys.
  2. Hold them like this for about 10 seconds.

The device will automatically reboot and turn on.

DFU (Device Firmware Upgrade) is a special mode originally intended to update the firmware of your device. It is also used for password recovery or jailbreaking (removing restrictions of official firmware).

Listening to tips for iPhone, it is impossible not to note two modes with similar functions - DFU and Recovery Mode. DFU mode can be called more effective and “rougher”.

Difference between DFU mode and Recovery

Its main difference from Recovery mode is that it bypasses the operating system, that is, when entering DFU, the iPhone does not even start loading iOS and directly flashes the firmware.

This mode is suitable for solving problems such as the inability to correctly complete a firmware update via iTunes in Recovery Mode, the inability to unlock the phone, and so on. However, we can recommend that you always use it first, so as not to accidentally create unnecessary problems for yourself and avoid unnecessary costs and effort.

Many inexperienced iPhone users confuse these two modes. In reality they are completely different. Now you will learn how to enable and disable Recovery mode and how to switch iPhone mode to DFU.

Recovery mode: how to enter

  • connect the cable to the computer, not to the device
  • hold down the “Home” button and continue to hold it, connect to the cable to the iPhone
  • wait until the cord icon appears on the display

How to exit Recovery Mode?

Press the “Home” button + the “Power” button for at least 10 seconds. You can also get by with a software solution by using the TinyUmbrella utility, which has a version for both Windows and Mac, to work with Recovery Mode.

DFU mode

The easiest way to enter or exit DFU is to use a specially created utility. It will indicate which buttons to press and how long to hold them. The iReb utility is also suitable for Windows.

To get started, you need to select your device on the main screen, and then follow the instructions of the program itself. To exit the mode, you just need to go to the next tab of the program. Then click “Set Auto-Boot True”.

Enter DFU mode using buttons

  • close iTunes
  • connect your phone to your computer
  • turn off your phone
  • simultaneously hold down the “Home” and “Power” buttons for 10-15 seconds
  • While continuing to hold "Home", release "Power"
  • wait for the computer to notify you that a new device has been detected
  • launch iTunes

That's it, your phone is in DFU mode. The screen will not display anything, while remaining completely black or completely white.

Exit DFU mode

  • connect the USB cable to the computer
  • hold down the Home and Power buttons for at least 10 seconds, then release them at the same time
  • press “Power” to turn on the iPhone

There is also a way to do without connecting to a computer - just hold down “Home” and “Power” for 10 seconds until the logo appears on the display. After this, the iPhone will boot into normal mode.
