The ways that exist to activate the DFU mode on your iPhone — 2022
In the day-to-day use of an iPhone, there are many bugs that can occur regarding software. In these situations, it may be necessary to access DFU mode to restore the operating system by reinstalling iOS on the iPhone. That is why it is necessary to know how this mode is activated on any device, and in this article we explain how to do it.
What you should know about DFU mode
DFU is the acronym for Device Firmware Update in English. Very briefly, it is a process that is integrated into iPhones and iPads so that interaction with iTunes or Finder is forced. And although in many cases it can be said that it is the same as a recovery mode, the truth is that there are some important differences. The main one is that the DFU mode will always allow you to change and choose the firmware that you will have installed on your device. In this way we are facing a mode that is mainly used to install a previous version of iOS.
Obviously, it is a mode that should not be abused too much. It is indicated for exceptional use when the rest of the options available have failed. This is because it always takes time to carry out this process, which is of an advanced level for some people.
What problems should you use it for?
Before the uses that you are going to give to this DFU mode, it is mainly the resolution of problems related to the software. It is a fact that neither iOS nor iPadOS are perfect operating systems, and as they are used, some important problems can arise. Above all, you can have different bugs such as unexpected restarts or simply that the device enters a practically infinite loop. In these situations in which the device cannot be restored correctly through Finder or iTunes, it is necessary to resort to activating the DFU mode. It is a convenient way for the computer to detect that something is happening on the device in order to carry out the corresponding restoration.
Another situation where you will have to make use of DFU mode is when you have a beta version installed on your iPhone. In this situation you will have to activate this mode compulsorily, since being in a test version when you want to restore it cannot be done through normal channels. This is because the system does not detect an official version as such, but a test version. That is why when you want to remove a beta, you will have to opt for the DFU mode.
Can it be used on all devices?
This is a question that many people who want to use the DFU mode can ask themselves, since we are used to most features being limited to very specific devices. But in this case it should be noted that it can be used on any device. It is a characteristic of any iPhone and also iPod that is available from the factory. It is a fundamental tool as we will see to be able to solve relevant software problems.
In this way, you will not have any a priori limitation to be able to use this function. As is logical, we always recommend performing this operation on the iPhone when you have knowledge of what you are always doing. We are facing a process that can eliminate all the content of your device quickly, and irreversibly. That is why it must be used responsibly.
The different ways to activate it
Once you know why it is interesting to activate the DFU mode, or recovery mode, it is time to know the necessary steps to carry it out. It should be noted that depending on the device you are using right now the process varies slightly. This is something mainly related to design. But above all with the number of buttons it has, since it should be noted that in the case of the iPhone X forward the Home button was eliminated. Next we are going to divide the steps to be carried out depending on the equipment you have.
iPhone 8 or later
- Press and quickly release the volume up button.
- Quickly press and release the volume down button.
- Keep pressing the side button until you see the recovery mode screen.
iPhone 7, 7 Plus
- Press and hold the top or side button on the iPhone.
- At the same time, press the volume down button.
- Keep pressing them until the recovery mode screen appears.
iPhone 6s o anterior
- Hold down the home button.
- At the same time, press the top or side button.
- Keep holding them until the recovery mode screen appears.
What if the buttons are broken?
All the methods that we have shown in this article are related to the pressure on very specific buttons of the device in question. But there may be a situation where you have the iPhone with these buttons completely broken, or it is with an activation lock. In these cases we must tell you that there are no other alternative methods to those that we have previously commented on. Apple does not add another option to activate recovery mode, because it is the only method to be able to interact with the motherboard itself.
In this situation, the company recommends going to the Apple Store itself or any technical service. In this case, what will be done is to make a connection through its special equipment. This is something that you will not be able to do at home. That is why if you are faced with this situation, you should contact Technical Support in order to have an adequate recovery of your device.
what will happen next
But activating the DFU mode does not remain only on the iPhone, since once it is activated, different actions must be carried out. Upon activation, recovery information will appear on the screen requiring you to connect your iPhone to a Mac or PC. Next you will have to locate the device on the computer, because in the case of being on a PC you will have to open iTunes or on Mac you will have to carry out the search in the Finder itself. Likewise, the computer will always detect the device automatically and a pop-up message will appear so that you can decide what actions to carry out.
In this case, at first, it will try by all means to reinstall the software without deleting your personal data. This is ideal when a bug can suddenly occur, but you don't have any backups done. Likewise, it can also be restored by deleting the data or even forcing the update. Obviously, what will always be of interest is to perform a complete restoration, since it is called recovery mode for a reason.
Regardless of the option you have chosen, the system will try to download the software version for the device. Obviously, here the time will be variable depending on the connection you have to the internet. Note that if the download exceeds 15 minutes, the iPhone will automatically exit recovery mode and reboot to return to the main screen. That is why you must wait for the download to complete completely to reactivate the recovery mode as we have previously commented. While both Finder and iTunes will no longer download the software again, having it stored in their local files. Automatically, it will start to perform the update or restore.
