If you used a mobile phone of another brand before purchasing an Apple product, then you may not know what dfu mode is on an iPhone.

DFU (Device Firmware Update) is a special mode designed for iPhones, which is software for making changes to the device. This mode can be found in other brands, only it is called flash mode there.

To, for example, update the firmware or restore it on an iPhone, you must switch the gadget to dfu mode. This function is also used when you need to restore or save valuable information.

How to enable dfu

It's actually easy to do, you just need to follow the instructions:

1. Connect your device to your computer and turn it off.
2. Open Apple iTunes.
3. Hold down the HOME and POWER buttons simultaneously to boot the phone.
4. The Apple logo that appears indicates that dfu mode is not yet enabled, so press and hold the HOME and POWER buttons again, after ten seconds, release POWER, but continue to press HOME.
5. Hold the key until the iTunes window pops up on your computer, indicating that the iPhone has been detected in Recovery Mode. Click OK.
6. Once the phone is entered into the desired mode, an icon similar to the USB icon will become visible on the black screen, representing the hard drive.

How to turn on dfu without the POWER button

Sometimes it happens that the power key does not work or gets stuck, and logging into dfu is vital. Then do the following:

1. Download the DFU.zip file to your computer and extract it to a folder in this path: C: /DFU/.
2. Connect your gadget to your computer, but do not log into iTunes.
3. Now go to the Start menu on your computer and in the “Run” line enter these values: C: /DFU/ DFU iBSS.m68ap.RELEASE.dfu.
4. After a white screen appears on your iPhone, you can start changing the firmware.

When your iPhone is seriously frozen, the only solution is to put it into recovery mode and try to update or restore it through iTunes. Apple has changed the way you force reboot your iPhone X, so entering it into Recovery Mode or DFU Mode now needs to be done differently.

If you restore your iPhone through iTunes in recovery mode, all your data will be deleted. Always try updating your software through iTunes first.

As a rule, recovery mode is sufficient for ordinary users.

Do not confuse DFU mode and Recovery mode. In recovery mode, you will see a USB cable, an iTunes icon, and a link to support.apple.com/iphone/restore on the screen.

In DFU mode, you will not see anything on the screen, the screen remains completely black.

The difference between DFU and Recovery Mode is that a fundamentally different approach to recovery is used.

Entering Recovery Mode

First, iTunes needs to be updated to the latest version available. If it is already open on your computer, you need to close the program.

Step 2: ConnectiPhone X to the computer

Connect your iPhone X to your Mac or PC using the Lightning cable that came with your smartphone.

A window with options will appear in iTunes. Update And Restore device. Select Update, and the program will try to install the latest available version of the software, saving all your data. If your iPhone exits recovery mode during the download process, don't worry and just repeat the steps.

Step 5: Set UpiPhone X

Once the update is complete, use iTunes to set up your iPhone X.

Note: If you want to exit recovery mode, disconnect iPhone X from your computer and press the side button to turn it on.

More and more often people come to me with the question of what to do when the iPhone or iPad does not turn on and does not respond to being connected to a charger or computer. It is impossible to pinpoint the exact cause of this “phenomenon.”

This could be an unsuccessful firmware update or an incompatible tweak from Cydia. Whatever happens to your device, the main thing is that it is not water.

If the device cannot be started and restored using conventional methods, you can only use a special firmware recovery mode. Today I will tell you how to put your iPhone (iPad) into DFU mode and bring life back to your gadget.

What is DFU mode

DFU(Device Firmware Update) is a special mode in which you can restore the iOS device firmware when any other attempts to restore the device have failed.

DFU mode is only necessary when:

STEP 3 - Continue holding the HOME button until iTunes displays the message " Recovery Mode" This may take 15 to 30 seconds, so don't panic.

You may need to enable this mode on your gadget if your device refuses to load the iOS operating system; in general, DFU mode will help you if your iPhone or iPad simply does not work.

DFU mode will allow you to quickly and safely restore your iOS operating system to a working state.

Before you start enabling DFU mode on your iPhone or iPad, you must connect it to a personal computer on which the latest version of iTunes is installed. If you don’t have the program, then download and install it right now, you can do this on this page - http://www.apple.com/itunes/

Entering DFU mode

• Hold the Home button until a message appears on the screen of your personal computer to which your iPhone or iPad is connected that the device is in recovery mode.

The above instructions are universal for launching DFU mode like on an iPhone smartphone, and on the iPad tablet computer.

Important nuances

If, when performing the above operations, an image of the iTunes program logo appeared on the screen of your iPhone smartphone or iPad tablet computer, then for some reason you were unable to enter DFU mode, so I recommend doing the above operation again until until you succeed.

If you use JailBreak or like to do other experiments on your iPhone, then there is a chance that at one not-so-great moment it will stop working. Fortunately, Apple anticipated such problems and developed tools that allow them to be solved.

One of the most effective tools of this kind is the so-called DFU mode. In this article, you will learn what DFU mode is, how to put your iPhone into DFU mode, and how to get your iPhone out of this mode if you suddenly need it.

DFU mode or Device Firmware Update is a special operating mode for Apple mobile devices. 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 the iPad and other mobile devices with iOS) after problems with updating, installing JailBreak, or other software failures that render the iPhone inoperable.

It should be noted that DFU is not the same as recovery mode. DFU mode bypasses the iOS operating system. Therefore, the iPhone can be put into DFU mode even after serious iOS failures. While recovery mode works through iOS and may not be available.

The process of entering an iPhone into DFU mode is very similar to the process of entering recovery mode. Therefore, if you do something wrong, you may end up in recovery mode instead of DFU. But it's not a problem. In this case, you just need to restart your iPhone and try again.

The first method of entering the iPhone into DFU mode is a little incorrect, but it is as simple as possible. This makes it optimal for novice users. Using this method, you will most likely be able to enter your iPhone into DFU mode on the first try. But, if you want to do everything as correctly as possible, then it is better to use the second method, which is described a little below.

So, a simple way to put an iPhone into DFU mode includes the following steps:

1. Connect your iPhone to your computer using a cable. When connecting, you do not need to use any adapters, just a regular USB cable.
2. Launch iTunes. If synchronization or backup begins after starting iTunes, wait until the process finishes.
3. Press the Power/Lock and Home buttons on your iPhone at the same time. Continue holding down the Power/Lock and Home buttons for 10 seconds.
4. After 10 seconds, release the Power/Lock button but continue to hold the Home button.

If after completing this procedure, your iPhone screen remains black, and the “Restore iPhone” button appears in iTunes, then this means that you have successfully entered the iPhone into DFU mode.

If the iTunes program icon and a cable image appear on the iPhone screen, then you have entered recovery mode (not to be confused with DFU mode). The Apple logo may also appear on the screen, which means that the iPhone has started to turn on in normal mode. You may have held the buttons down for too long.

How to properly enter iPhone into DFU mode

The second method is more complicated, but it is also more correct. This is what most foreign sites recommend using. The disadvantage of this method is that it is quite difficult to do it correctly. At the slightest error, the iPhone boots in normal mode or goes into recovery mode, and this is not what we need.

So, the correct way to enter an iPhone into DFU mode involves the following sequence of actions:

1. Connect your iPhone to your computer using a cable. As in the previous method, you need to connect directly, without using any adapters.
2. Launch iTunes and wait until the synchronization or backup process (if it has started) finishes.
3. Turn off your iPhone as usual. To do this, you need to press the “Power/Lock” button, hold it for a couple of seconds and turn off the iPhone using the slider on the screen. After turning off, wait a few seconds for all programs on the iPhone to finish their work.
4. Press the “Power/Lock” button and hold it for 3 seconds.
5. After three seconds, without releasing the “Power/Lock” button, press the “Home” button and hold both buttons for another 10 seconds.
6. Release the Power/Lock button but continue to hold the Home button.

If, as a result of these actions, the iPhone screen remains black, and iTunes offers “Restore iPhone,” then this means that you have entered the iPhone into DFU mode.

As with the previous method, an iTunes program icon and a cable image may appear on the iPhone screen, this means that you have entered recovery mode (not to be confused with DFU mode). The Apple logo may also appear, which means that the iPhone has started to turn on normally. You may have held the buttons down for too long.

How to get iPhone out of DFU mode

Getting an iPhone out of DFU mode is much easier than entering it. All you need to do is disconnect your iPhone from the computer, if it is connected, and hold down the Power/Lock and Home buttons for 10 seconds. After 10 seconds, the iPhone will reboot and start up normally.

If, as a result of the steps described above, you entered the iPhone not into DFU mode, but into recovery mode, then you need to do exactly the same. Disconnect the iPhone from the computer and press the “Power/Lock” and “Home” buttons for 10 seconds.
