If you need to use DFU to restore your iPhone, this article will prove very useful to you. In it, we are going to be looking at what is iPhone DFU mode, how to put your iPhone in DFU mode, and get it out of DFU mode as well as the main difference between DFU and Recovery Mode.
Let’s get started.
DFU mode is a state that you can put your iPhone into where the device’s operating system or bootloader doesn’t load but the device still interfaces (communicates with) iTunes. DFU is an acronym for “Device Firmware Update” and it is intended for advanced users only.
This is why people often choose DFU mode when all other troubleshooting options fail to produce the desired results.
DFU mode is therefore useful when an iPhone is completely unresponsive, it is bricked, or when the user wants to downgrade the device to an older version of iOS. It can also be very useful when you want to install custom firmware to the device for jailbreaking or SIM unlocking purposes.
One of the main ways that DFU mode differs from recovery mode is that a device in DFU mode will interface with iTunes without iTunes automatically installing the latest iOS firmware into the device. When you put your device in recovery mode and connect it to iTunes, iTunes will restore the device while installing the latest version of iOS and firmware on to the device.
DFU mode lets you change and choose the firmware you want to install onto your device. therefore, you could use DFU mode to install a previous version of iOS if you want.
It is however important to note that if you restore your device in DFU or recovery mode via iTunes, you will lose most of the data on the device, in-app data that wasn’t included in the last iTunes backup, and any modifications to the device’s settings.
Like we mentioned before, DFU mode is intended for advanced users only. The main reason, however, that most people choose to use DFU mode is they want to change or update the firmware and iOS on the device to fix problems with the device or just because they want the features in a particular version of iOS.
DFU mode, therefore, becomes the best solution for a bricked device or a device that is disabled and won’t respond to any of the normal troubleshooting solutions. But the majority of people who use DFU mode, do it to downgrade their current version of iOS to another firmware package that they prefer.
DFU mode also proves very useful in installing custom firmware, often required when jailbreaking or unlocking the SIM on an iOS device.
The method to put your iPhone in DFU mode will depend on the device model. The following is a description of how to put an iPhone in DFU mode for all device models:
