How to enter your iPhone or iPad into DFU. Non-standard way. How to put your iPhone into DFU mode using iTunes How to disable dfu in iphone 4
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 enter the iPhone into a special state to perform certain operations: creating the necessary partitions in file system, start/firmware of the bootloader, as well as firmware of 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 can cause similar problems? It could be unsuccessful firmware, a hack or an aggressive application from Cydia - it doesn’t matter. It's much more important to know how to fix it.
It’s worth noting right away that you can enter an iOS device into DFU mode only by iTunes programs– sometimes without it, i-devices, including the iPhone 7, are even afraid to sneeze.
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, before starting all manipulations via DFU, it is better to make a copy of everything that is on your smartphone in cloud storage or directly to your computer.
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:
- You need to connect your iPhone to your computer - you need iTunes already turned on.
- 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 the mode was turned on Recovery Mode:
Here it is worth emphasizing the fundamental difference in the iPhone between DFU and Recovery mode, so that inexperienced users stop confusing them:
- Recovery Mode operates within operating system, is considered “softer” and does not require iTunes to be enabled.
- 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:
- First, you need to completely turn off your iPhone.
- 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 the iPhone 3g and ends with the iPhone 4s (which does not prevent you from using the 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.

Not an easy task at times...By the way, in some cases, after a successful opening, replacing the battery can help.
