DFU mode iPhone: How to enter DFU mode and why is it needed? Possible ways to put iPhone into DFU mode DFU mode does not turn on.

DFU mode is used in cases where your iPhone or iPad does not load the iOS operating system and you need to restore its functionality.

The phone (or tablet) must be connected to the computer via a USB connector, and iTunes must be installed on the computer, preferably latest version(can be downloaded from here).

Entering iPhone/iPad into DFU mode

  1. Press and hold the Home button and the iPhone Power button at the same time and hold them both down for 10 seconds. A simple tip for counting 10 seconds: say the number “22” (“twenty-two”) 10 times in a row, out loud or silently, at a calm and measured pace. The pronunciation of “twenty-two” lasts approximately 1 second.
  2. Without releasing the lower Home button, release the upper iPhone/iPad on/off button and continue to hold the lower Home button until iTunes displays a message on the computer screen indicating that a device has been detected in recovery mode (takes up to 10 Seconds).

Attention!

  1. All this time, the iPhone or iPad display will remain dark! Many of those who are faced with the introduction of an iPhone/iPad into DFU mode for the first time find it difficult to perform these simple steps because they are worried about the condition of their favorite device, are nervous and not sure that they are doing everything correctly, and also do not receive any feedback from the phone, since all this time its screen remains black. No need to worry, do everything calmly and confidently. And everything will work out!
  2. If either the Apple logo (apple) or a USB cable leading to the iTunes icon appears on the screen, as in the picture below, then it means that you were unable to enter the phone into DFU mode and you need to repeat it all over again.

When restoring the firmware of an iPad or iPad via DFU mode, the data on the device will not be saved, but it can be restored from backup copies iCloud or iTunes.

DFU refers to a device firmware update. There could be many reasons you might want to enter DFU mode. If you want to jailbreak your iPhone or unjailbreak it, the device firmware update mode can be used. It can also be used to update expired betas. Also, if there is a problem with your iPhone and nothing seems to work, including recovery mode, the device's firmware update mode may be your last hope.

So what happens in Device firmware update mode?

DFU puts your phone in a state where it can communicate with iTunes on your computer (whether Windows or Mac works for both). However, this mode does not load IOS or bootloader. Because of this, the device can be removed from any state. This, in fact, is the main difference between recovery mode and device firmware update mode.

It's better to try recovery mode or iOS system recovery before trying the device in firmware update mode. DFU mode is a last ditch attempt to get your phone out of any trouble, unless you intend to jailbreak the phone, or unjailbreak it, in which case it should be done. Recovery mode or system restore can solve most problems.

In this article, we have collected 6 popular DFU tools and we hope it will be useful for you to enter DFU mode.

How to enter iPhone into dfu mode - the difference between DFU and Recovery Mode

Many iPhone users have encountered the recovery mode (in the English interface “Recovery Mode”), but they did not understand how it differs from the mentioned DFU. The first leaves your device in working condition: you see the picture on the screen, the phone responds to touch. The second option involves working with the phone without directly logging into the shell. In other words, the device does not respond to any touches or button presses, and its screen remains black and blank.

Algorithm for entering iPhone into DFU mode

So you'll need your phone, Personal Computer and a usb cord through which you connect the device.

Connect your iPhone to your laptop or computer via cable, and be sure to turn it off.

  • wait a couple of seconds from the moment the device is turned off,
  • now simultaneously hold down the Home button, which is located in the center of the phone at the very bottom, and the Power button at the end,
  • count exactly ten seconds to yourself,
  • release your finger from the end of the phone, from the Power button,
  • continue to hold down the Home key,
  • after a couple of seconds, your computer will recognize the iPhone in DFU mode,


  • if nothing happens on the screen, simply repeat the algorithm again. It is also possible that you simply held the buttons down for too long or not enough. Hold both buttons again and count to ten; if this does not work, just look at the second hand of the clock.


How to Enter iPhone into DFU Mode Without Pressing Buttons

If you know for sure that one of the Home or Power buttons is broken or the algorithm described above does not work. Then try following the instructions in this article below:

  • download the “DFU” utility, that’s what it’s called,
  • save it to your computer on drive C,
  • connect iPhone via cable,
  • make sure that the iTunes application is definitely disabled even in the background,
  • call command line, by pressing Win + R or on laptops Fn + Win + R,


  • Type the following phrase into the command line “C:/DFU/DFU iBSS.m68ap.RELEASE.dfu” without quotes and press Enter.


Your Apple phone is now in DFU mode without buttons.

There is also a second utility called “redsn0w”, it modifies the firmware directly. Download it and install it. Then go to the following parameters: “Extras – Even more – DFU IPSW” and wait for several minutes until the program itself creates new file firmware.

Now you can launch iTunes and flash your phone by selecting the created file. The utility's function is that it adds an algorithm to the IOS firmware file that automatically puts the iPhone into DFU mode before installing the update. After this, the problem of your phone entering DFU mode will no longer bother you.

Any iPhone, iPad or multimedia tablet iPod touch can be entered in DFU mode. To be honest, I myself have never entered my iPhone into DFU mode; they say that beginners do not succeed right away; to enter the device into this mode, you need to get used to it, which is what we will do today. We will take as a sample for experiments Apple iPhone. The peculiarity of entering DFU mode is a completely black screen, and no identifying marks on iPhone screen, if the transfer to DFU was accompanied by at least an inscription, as in the picture on the left, then it would be a little clearer.

Besides 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 crashes and the iOS firmware does not start; in such cases, Recovery Mode and DFU are used. 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 don’t get confused, I’ll try to explain what the difference is between them:

  • When you put your iPhone or iPad into Recovery Mode, appears on the device screen. When entering DFU, the device screen shows a black display.
  • You don't have to use iTunes to enter Recovery Mode. I can’t start DFU mode without iTunes, I tried it myself.
  • Recovery Mode is launched using operating system iOS, and the DFU mode bypasses the operating system, i.e. at the hardware level.

How to put iPhone into DFU mode

We will look at two combinations that can put our iPhone into DFU mode. You can use any one that is more convenient. Before we begin, launch iTunes on your computer and connect your iPhone or other gadget to it using the included cable. Do not use USB adapters; plug the cable into the computer itself. After the iPhone is connected to a computer running iTunes, we try to put the phone into DFU mode using one of the methods below:

Method 1. How to log into DFU

Putting iPhone into DFU mode. Method No. 1

The easiest way to enter an iPhone into DFU is as follows: simultaneously hold down the Home button plus the Power button and count to 10. After holding it for 10 seconds, release the Power button and continue to hold the Home button.

Method 2: Second attempt to enter DFU

Step by step launching DFU mode on iPhone. Method No. 2

This method is called more correct, but it is more difficult for beginners. and wait for the device to turn off completely. Now hold down the Power button and after counting to 3 seconds, press and hold the Home button in the same place. Now, while holding Home + Power, count to 10 and release Power, but continue to hold the Home button.

iTunes program while starting DFU mode

When finishing putting your 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 the device with DFU mode running and display the following message:

iTunes detected the iPhone in recovery mode. You must restore this iPhone before using it with iTunes.

If you see such a notification, and a single button appears in iTunes - Restore iPhone, now look at the phone screen, if the screen is black, then it is in DFU mode. If you pressed something incorrectly, an image with the iTunes logo and a USB cable may appear, which means this is Recovery Mode.

How to exit iPhone into DFU mode

If, while reading the instructions, you entered your working iPhone into DFU mode, you can remove the phone from it using the usual method - by holding Home buttons+ Power for 10 seconds. The phone will reboot and work normally. To exit the manually launched Recovery Mode, we used the same method of exiting Home + Power for 10 seconds. With the cable connected, after holding Home for 10 seconds and Power phone may not start, then press the Power button and it will turn on.

One day, after an unsuccessful attempt to update the firmware, the firmware got out and our iPhone fell into a permanent recovery mode, from which only . Perhaps, if the iPhone does not exit DFU with a reboot, then you can try programs like TinyUmbrella or iReb. I have not encountered such a situation yet, but if I do, I will definitely tell you.
