How To Put Your iPhone or iPad Into DFU Mode


DFU mode is a ‘Device Firmware Update’ mode of your device. You have to switch your iPhone or iPad to DFU mode every time you try to Jailbreak or update latest iOS release on your device. Many users fail to successfully install iOS or Jailbreak because they are unable to turn their devices into DFU mode. Athough many iOS updates and jailbreaks automatically switch your device to DFU mode, some jailbreaks do require you to do it manually. In case of downgrading your iOS, you have to switch your device to DFU mode on your own. If you are trying to update iTunes on your device from beta or GM firmware, again you have to turn your device to DFU mode.

DFU mode and recovery mode are two different modes. Switching your device to DFU mode is not as simple as switching your device to recovery mode. Timing plays an important role and you need to do a lot of practice before doing it successfully. It may take some time, so do not worry and keep trying the below mentioned method of turning your device to DFU mode. So let’s see How you can put your iPhone or iPad in DFU mode:

Step by Step Guide

  1. Connect to a computer: First step is to connect your device with Windows or Mac computer. Keep iTunes running on your device while connecting.
  2. Hold Buttons: The most important step is to hold down multiple buttons simultaneously. Hold down the home button and the two sleep buttons on top of your device together.
  3. Timing: It is most important to keep all buttons held down for at least 10 seconds. This may need some practice as over holding will display the apple logo on your screen, meaning that you have to start all over again.
  4. Switching Buttons: After 10 seconds, let go of the two sleep buttons but keep your finger on the home screen for at least 5 more seconds. Again, timing is crucial as over holding may result in “Plus into iTunes” message that means that you have to do it again.
  5. Done: If you managed to do this properly, the color of the screen stays black. This means that you have successfully turned your device into DFU mode.

This is the time when iOS downgrade or jailbreak controls your device. After the jailbreak or iOS are done playing with your device, iTunes displays an alert message on your screen saying it has detected your device and it needs a reboot.

Some people may be still confused about the recovery mode and the DFU mode. The basic difference between both modes is that the DFU mode can allow you to downgrade while recovery mode does not allow you to downgrade your device. Recovery mode implements iboot while DFU mode bypasses iboot.
