How to recognize DFU mode?

DFU in an iPhone or iPad can only be recognized when the device is connected to a computer and only using a USB cable. It is the computer that will notify the user about the device firmware update mode. iTunes recognizes "Device Firmware Update" mode as 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 is an emergency mode and is recognized by iTunes when connecting the device to a computer as a recovery mode. In this case, the iPhone works without loading the system shell, so pictures and the device are not visible on the iPhone screen does not respond to key presses and does not turn on the display.

Different from recovery mode ( Recovery Mode) because 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 normal mode.

DFU mode on iPhone (firmware updates) is constantly confused with Recovery Mode. In fact, the difference is huge, and it is as follows:

Recovery Mode – a softer mode compared to DFU; The iPhone gets into Recovery Mode using the iOS operating system, and into DFU Mode by bypassing it. DFU mode is applied only when Recovery Mode refuses to help. DFU mode cannot be accessed if the device is not connected to the iTunes media combiner. To enter Recovery Mode, it is not necessary to connect the gadget to the PC.

There are also external differences between the two specific modes. The gadget in DFU MODE has a completely black screen, without the Apple logo; the gadget does not respond to pressing “Home” and “Power” separately. The USB cable and the iTunes icon are visible on the display of the smartphone in Recovery Mode.

How to put iPhone 6 into DFU mode

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.

The process of entering the iPhone into DFU mode is very similar to the process of entering recovery mode

You can put your iPhone into DFU mode using the buttons located on the device's body. For iPhone models up to version 6 inclusive, the operation algorithm is slightly different from entering recovery mode for later versions.

1. Connect the device to your PC using a USB cable
2. Launch iTunes on your PC. Attention: the latest version of the program must be installed on your PC.
3. Press and hold the Power and Home buttons at the same time for 10 seconds.
4. Release the Power button, leaving the Home button pressed for 10 seconds. A message should appear on your computer screen in iTunes indicating that your device is in recovery mode. The display of the phone itself will remain black.
5. In iTunes, select the "Restore iPhone" option to reset your phone to factory settings. After this, all personal data will be erased, and the latest version of the system will be installed on the iPhone.
6. To exit recovery mode, press and hold the Power and Home buttons at the same time for 10 seconds, after which the device will turn off. The next time you turn on (by pressing the power button), the device will boot into normal mode.

No matter how reliable the iPhone 6 is, it is not immune to various types of failures. In some cases, the phone stops responding to any user actions: the screen does not light up, the buttons are inactive. In order to get it out of this state, the developers provided the dfu mode. The abbreviation dfu stands for: device firmware update, that is, updating device firmware.

This mode is an effective tool that helps you successfully recover your iPhone from many emergency conditions. They occur especially often after iOS updates, when the user tries to implement them on their device.

When activated, dfu acts as a bootloader, since the operating system, for one reason or another, does not do this. During the recovery process in this mode, the system is completely removed and reinstalled. All previous settings and personal data are erased, and the latest current version of iOS is downloaded to the phone. Then personal information can be restored, provided that you have backup copies of it.

How to initiate dfu

This is a very important and necessary function, let's take a closer look at how to enter the iPhone into dfu mode.
First, connect the switched-off device with a USB cable (preferably a branded one) to the authorized computer with which it was previously paired (since you will not be able to enter confirmation from a non-working iPhone to connect to a new device).

Secondly, simultaneously press and hold the “Home” and “Power” buttons pressed for ten seconds.

Thirdly, release the “Power” key and hold down the “Home” key until a characteristic iTunes notification appears on the computer monitor that the device is under dfu mode. (It is recommended to update iTunes to the latest version before this to avoid errors)

At the same time, the phone itself does not reflect the successful completion of this mode. His screen is still disabled and cannot display any system messages. The computer will carry out all further processes itself. It must be connected to the Internet, as you will have to download the latest version of iOS from the Internet. This may take more than one hour until all file system partitions are successfully installed on the phone.

If you cannot switch your iPhone to dfu mode the first time, try repeating the entire procedure a little later using the original USB cable.
As you can see, putting your iPhone into DFU mode is not at all difficult. Let's now find out how to get him out of it.

How to disable already running recovery mode on iPhone 6

If, after starting dfu mode, you change your mind about restoring the system so as not to lose all existing data, then you can easily remove your iPhone from it. To do this, it is enough to perform a regular reboot, i.e. Press the Power and Home keys and hold for ten seconds. After turning on the power, the phone will start loading into normal mode (provided that it was operational before). It makes sense, as a training, to carry out this process before problems arise. So that later you can be prepared and not make mistakes.

In conclusion, we will say that you should not neglect the use of this mode. It will help restore your phone in cases of system failures, or when the current update has gone wrong, and also if you have forgotten your password. If you have a backup, you will copy all your data again, and your iPhone 6 will work like a Swiss watch.

How to put iPhone into DFU mode? Many users of Apple products have never even heard of this, at least until the device works unconditionally and nothing needs to be restored. But, after certain procedures, such as jailbreaking (hacking), even a brand new iPhone 7 is capable of going on strike, and iPhone 5 even more so can “deny service.” Therefore, sometimes there is no other choice but to restore the original firmware. Before you figure out how to restore your iPhone, you need to enable the required mode.

After all, it is often possible to “resurrect” an iPhone only by enabling DFU. By the way, jailbreaking itself is also done through it. How exactly does all this work on an iPhone and what is DFU mode?

Device Firmware Update (DFU) is a special recovery mode that allows you to put the iPhone into a special state to perform certain operations: creating the necessary partitions in the file system, starting/flashing the bootloader, as well as flashing additional modules and system partitions. It can also be used to recover your password.

So, what DFU mode is is clear. In what cases will you need to put your smartphone into recovery mode?

• The device refuses to turn on;
• Standard recovery measures do not apply;
• Inability to recharge;
• The computer does not see the iPhone.

What could cause such problems? It could be a bad firmware update, a hack, or an aggressive application from Cydia - it doesn’t matter. It's much more important to know how to fix it.

It is worth immediately noting that you can enter an iOS device into DFU mode only through the iTunes program - sometimes i-devices, including the iPhone 7, are even afraid to sneeze without it.

How to put your iPhone into DFU mode?

It is important to warn you: the procedure for restoring an iPhone in this mode destroys everything that was stored on the device, no matter how sad it may sound. Therefore, it is better to make a copy of everything on your smartphone to cloud storage or directly to your computer before starting all manipulations via DFU.

And a small rule: the connection should only be made via the original cable (preferably) to the rear USB ports. It is not advisable to use front inputs and adapters. This especially applies to the iPhone 7. The newer the model, the more vagaries.

The procedure describing how to enter DFU mode is not easy, but on the fifth attempt everything will definitely work out. But especially gifted users may be able to cope with the task right away.

So, to log into DFU:

1. You need to connect your iPhone to your computer - you need iTunes already turned on.
2. Next, you need to hold down the Home and Power buttons for 10 seconds, then release Power, but continue to hold Home.

It didn’t help and the iPhone won’t enter DFU mode? How was it decided? After all, even after entering DFU mode, the iPhone screen remains completely black, and this can only be determined by looking at the iTunes messages. If everything is done correctly, the tuna will display the following message:

But if such an image appears, it means that Recovery Mode was enabled:

Here it is worth emphasizing the fundamental difference in the iPhone between DFU and Recovery mode, so that inexperienced users stop confusing them:

1. Recovery Mode operates within the operating system, is considered “softer” and does not require iTunes to be enabled.
2. DFU works bypassing the operating system - at the hardware level. Therefore it is more effective.

How to enable the first mode will not be discussed here - so if the iTunes and USB cable icon appears on the iPhone screen, you can safely start the procedure all over again.

A more complex method to put iPhone into DFU recovery mode:

1. First, you need to completely turn off your iPhone.
2. Now the Power button is pressed for three seconds, then the Home button is pressed, held together for 10 seconds, then, just like in the first case, Power is released, and Home continues to be held.

Failure again? However, this is strange... Then for especially lucky users there is the iReb program, which will tell you how to switch the iPhone to the desired mode.

The lightweight utility will control the entry of the iPhone into the required DFU mode - you just need to select the appropriate device, the list of which starts from iPhone 3g and ends with iPhone 4s (which does not interfere with the use of iPhone 5s, iPhone 6s and iPhone 7), and then just follow the instructions that appear on screen.

Didn't work out again? It is possible that the Home button refuses to obey. In this case, the RedSn0w program will help. You need to launch iTunes, connect your iPhone and open this utility. Then all you have to do is click on the pwned DFU button so that iTunes indicates that you have successfully entered recovery mode.

Let's say it worked, and all the necessary procedures have been completed. How can I restore the device to its previous state?

How to remove iPhone from DFU?

It's simple - to perform the withdrawal you need to hold the Home and Power buttons for 10 seconds, thereby rebooting the device.

A small nuance before removing the iPhone from a special state: you do not need to immediately disconnect the cord from the PC without completing the steps described above.

Otherwise, another problem may arise - the capricious gadget will not want to exit DFU mode. Why is this happening and what to do?

This happens due to a simple malfunction of the system, even if it is an iPhone 7. Sometimes programs such as TinyUmbrella, RedSn0w, RecBoot and iReb help to remove the smartphone from the ill-fated mode. How to return your smartphone to normal using RedSn0w?

You just need to re-enter the previous mode using this program, and then try to exit DFU by rebooting.

Everything is useless and again it is not clear how to exit recovery mode? Then you can try to recharge the battery. However, to do this you will have to remove the back cover using a screwdriver and suction cup. Not an easy task at times...By the way, in some cases, after a successful opening, replacing the battery can help.

Last resort

If it was not possible to exit DFU mode, then there is only one way out. This is a complete re-flashing - it mostly helps.
