How to put iPhone in DFU mode

4 minutes of reading / By

DFU is the abbreviation of Device Firmware Upgrade mode which allows the restoration of a device from the current state. In this mode, the boot-ROM may accept iBSS. Moreover, DFU is burnt into the hardware as a part of secure-ROM, so removing it is not possible. Although DFU mode resembles the most obvious recovery mode they aren’t the same, because in recovery mode the device is reverted to factory settings with the latest iOS available whereas, in DFU mode, iTunes can still communicate with the device but cannot upgrade its software to the latest version automatically.

Now, here’s how you can put your device in DFU mode-

Preliminary knowledge

  • Below the display of your iPhone, the circular button is the Home Button.
  • The power button is known as the Sleep / Wake Button.
  • Firmware is the bridge between hardware and software which means that it controls the functionality of a given device.
  • During a DFU restore, your pc or mac completely erases all the coding present on the device that controls it and if even a small issue arises, then it can potentially harm the device.
  • Water damaged iPhone shouldn’t be used for this, as it sometimes wrecks it functionality completely if the restore doesn’t complete.
  • Your device can be on or off before its put in DFU Mode.

 How To Check If The Device Is In DFU Mode

  • If the device display shows Apple’s logo, the steps weren’t executed correctly and the device is rebooted. The steps need to be repeated all over again.
  • If the iPhone shows the logo of iTunes, the steps weren’t executed correctly and the device has entered recovery mode. The device needs to be restarted to exit recovery mode.
  • If iTunes does not prompt a detected iPhone in recovery mode, it means that the device isn’t in DFU mode.
  • If the device display isn’t black, shows that the device hasn’t entered DFU mode.

How To Exit DFU Mode

Your device will exit DFU mode automatically once it has been restored successfully. But in case, the user enters DFU mode by mistake and needs to return to normal functionality by exiting DFU mode, then just hold the Volume button with the Sleep / Wake button till Apple’s logo starts to appear.

 

 

DFU mode is simply the perfect way to install previous versions of iOS, update the firmware, or just fix an unresponsive device. It can also be used to verify the hardware, and the functionality of the right software, due to which DFU mode is extremely essential for jailbreaking your iPhone.
