How to recognize DFU mode?

DFU in an iPhone or iPad can be recognized only when the device is connected to a computer and only with a USB cable. It is the computer that will notify the user about the device firmware update mode. iTunes recognizes the "Device Firmware Update" mode as a recovery mode.


What is DFU Mode? How is it different from recovery mode?

DFU-mode (Device Firmware Update) is a device firmware update mode. It refers to emergency mode and is recognized by iTunes when the device is connected to a computer as a recovery mode. In this case, the iPhone works without loading the system shell, so the iPhone screen does not show the picture and the device does not respond to key presses and does not turn on the display.

Differs from recovery mode ( Recovery Mode) the fact that in this mode the device does not show visible signs of life (the control button does not work, there is no image on the display) In some cases, this mode helps to correct a minor software glitch and allows you to reboot in the normal mode.

Any iPhone, iPad, or multimedia iPod touch can be entered into DFU mode... To be honest, I myself have never put 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 we will do today. We'll take the Apple iPhone as a model for experimentation. The peculiarity of entering the DFU mode is an absolutely black screen, and there are no identification marks on the iPhone screen, if the translation into DFU was accompanied at least by an inscription, as in the picture on the left, it would be a little clearer.

In addition to 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 crashed, and the iOS firmware does not start, in such cases, the Recovery Mode and DFU modes are used. To begin with, they always try a milder mode - Recovery Mode, but if it does not help, then they already use the DFU mode.

Sometimes DFU is confused with Recovery Mode. Whatever you get confused, I will try to explain the difference between them:

  • When you enter iPhone or iPad into Recovery Mode, appears on the device screen. When entered into DFU, the device screen displays a black display.
  • It is not necessary to use iTunes to enter Recovery Mode. I can't start DFU mode without iTunes, I tried it myself.
  • The Recovery Mode is launched using the iOS operating system, 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 in DFU mode. You can use any more convenient one. Before we start, launch iTunes on your computer and connect your iPhone or other gadget to it using the supplied 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 in one of the following ways:

Method 1. How to log into DFU

Putting iPhone into DFU mode. Method number 1

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

Method 2. Second attempt to enter into DFU

Step-by-step launch of DFU mode in iPhone. Method number 2

This method is called more correct, but it is more difficult for beginners. and we are waiting for the device to turn off to the end. Now we hold down the Power button and after counting up to 3 seconds in the place with it we hold down the Home button. Now holding Home + Power, count to 10 and release Power, but continue to hold the Home button.

ITunes while starting DFU mode

When completing the iPhone input into DFU mode, it is useless to watch the phone screen, since it will simply be black, you need to look in the running iTunes program, which will detect the device with the DFU mode running and display the following message:

ITunes detected iPhone in recovery mode. You need to restore this iPhone before using it with iTunes.

If you saw such a notification, and the only button appeared in iTunes - Restore iPhone, now look at the phone screen, if the screen is black, then it is in DFU mode. If you did not press something correctly, an image with the iTunes logo and a USB cable may appear, which means this is the Recovery Mode.

How to get iPhone into DFU mode

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

Once, after an unsuccessful attempt to update the firmware, I got out and our iPhone went into a permanent recovery mode, from which it only helped. Perhaps, if the iPhone does not exit DFU by rebooting, then you can try programs like TinyUmbrella or iReb. So far, I have not encountered a similar situation, but if I come across, I will definitely tell you.

When you try to restore your device, an unpleasant thing can happen - your phone or tablet will go into perpetual recovery mode. How to enter and exit the iPhone from DFU Mode will be described later, but first you need to understand what this mode is and why it is needed.

What is DFU Mode for and how to enter it?

DFU is a special mode that is used for an emergency update, flashing or booting a device from a backup copy. It is used if the phone or tablet is frozen and does not respond to commands. DFU Mode works in tandem with the computer application iTunes, with the help of which all the operations for managing the firmware are carried out.

Why the device might freeze

But if some failure occurs during an emergency update or recovery of the device, then your gadget will face an eternal reboot. It looks like this: the device tries to turn on, but at a certain moment it encounters an error in the operating system and cannot overcome it, this problem causes the device to automatically switch to recovery mode. If in this situation you try to remove the device from DFU Mode, then it will start loading, again stumble upon an error and, accordingly, will return to DFU Mode. This cycle is called the Recovery Loop.

The following situations can cause the above problem:

  • Incorrectly loaded firmware. If the iTunes files were damaged or not updated to the latest version, or the Internet connection was disconnected during the download process, then the IOS for your phone or tablet may not download correctly.
  • The restore or update process was interrupted before it was completely finished. The USB cable may have been unplugged too early, or the device may have ended charging too early.
  • If you tried to downgrade the firmware of your device, then this could also cause a recovery loop.
  • Perhaps the device itself was damaged: the error lurked in the operating system, or the insides of the phone or tablet had physical flaws.

How to enter iPhone or iPad into DFU Mode

First, connect your phone or tablet to your computer using a USB cable and disconnect it, and then use one of the methods below to enter DFU Mode.

How to switch to mode by holding the Home + Power buttons

Transition by alternately pressing the "Lock" and "Home" buttons

The result for both options should be a message from iTunes on the computer screen, which says that a device is connected to the computer, which is subject to authoritative recovery. Remember that nothing should be displayed on the phone or tablet screen, there should only be a black solid color screen throughout the entire process.

Output iPhone, iPad, iPod touch from DFU

If the device is not in an eternal reboot and no errors occurred during the recovery or update process, then a simple reboot will help: pick up your tablet or phone and hold the Home and Lock buttons for 10 seconds. Done, the device will automatically restart and return to normal operation.

Through special programs

If your device falls into the so-called "recovery loop", that is, after each reboot, it automatically returns to DFU mode, then one thing remains - to use third-party computer programs that will help to cope with the problem that has arisen.

TinyUmbrella

  1. We connect the computer to the device using a USB cable.
  2. Download and install the program from the developer's official website - http://blog.firmwareumbrella.com. The site has installer files for both Windows and Mac OS.
  3. Put the device in DFU Mode. Instructions describing this process are found above in the same article.
  4. Wait until the program detects your phone or tablet in recovery mode and the Fix Recovery button becomes active. Click on it.
  5. You will be asked if you really want to fix the recovery process. Confirm the action. After that, wait a while, the device should turn itself on in normal mode.
  6. The process of exiting the recovery loop is complete, but it is worth considering two more useful buttons of the program you are using. The first - Enter Recovery, allows you to put the device into DFU Mode without using buttons. It can come in handy in the event that the physical buttons are faulty.
  7. The second button - Exit Recovery, allows you to exit recovery mode without using the device buttons. But this method only works if the device is not in an eternal reboot loop.

What to do if you cannot exit DFU mode

If the use of the above programs did not help, then one thing remains - try again to restore through iTunes. But this time everything should go without errors, otherwise the problem will not be solved. Before starting the operation, charge the device 60-100% so that the process is not interrupted at the most inopportune moment.

Exiting DFU - Step by Step


If none of the above methods helped you, including re-flashing through iTunes, then one thing remains - take the device to the service in order to get the help of a qualified specialist. Perhaps the insides of the gadget were damaged, in which case you will have to pay extra and replace them with new ones, of course, if the warranty for the device has already expired. But before taking the phone to the nearest service, contact Apple support, perhaps they can give you the right advice on how best to act in this situation - https://support.apple.com/en-ru.

So, the device can be switched to DFU Mode in order to perform a hard recovery or firmware update. But if this process is interrupted or carried out incorrectly, then the phone or tablet can go into eternal recovery mode, returning to DFU Mode from time to time after rebooting. In this case, a regular reboot, third-party programs or re-flashing can help you in compliance with all the rules. If all else fails, contact Apple support and the official device repair service.

DFU exit method regime on i-devices is determined by how the device was inserted into it and the presence of a jailbreak. Traditionally a fairly standard way, but in some cases it may be necessary to involve additional software.

Instructions

Go to the Recovery Mode Loop Fixer / SHSH Blobs Grabber tab and click the Set Auto-Boot True button. This action will take the device out of DFU mode.

2. Please note that the use of the iREB ​​application is implied only in devices with a jailbreak and cannot be used if there is an official firmware!

3. To get out of regime DFU in the standard way, press the Power button, located on the front of the device, at the same time with the Home button, which is located on the front of the screen. Keep both buttons pressed for 10 seconds.

4. Release both buttons and turn on the device in the usual way. To do this, press and hold the Power button until the Apple logo appears on the device screen.

5. Exit from regime DFU implies the need for a metamorphosis of the firmware of a mobile device. This operation can be performed in one of 2 recovery modes - Recovery and DFU. In order to switch to DFU mode, connect the i-device to the computer with the help of a special USB connection cable supplied with the package, but do not open iTunes. Disconnect the device using the standard method and press the Power and Home buttons at the same time.
