How to Put Your Device into DFU Mode

How to Put Your Device into DFU Mode

Learning how to reliably place your iDevice into DFU mode is a step that you must learn if you want to be an effective jailbreaker.
DFU mode stands for Device Firmware Upgrade mode and differs from the restore mode with the iTunes logo that you may be used to. DFU mode differs from recovery mode because it does not load the boot loader, hence you will see a solid black screen instead of the more friendly “connect to iTunes logo”. Getting into DFU mode is super easy, but it does require some practice. We generally recommend putting your device into DFU mode prior to even starting any jailbreaking actions, because it just makes the process more seamless.

To place your device into DFU mode, do the following:

Step 1: Connect your device to your computer
Step 2: Hold the Home + Power buttons on your device simultaneously for 10 seconds.
Step 3: Release the Power button without releasing the home button. Continue holding Home for another 10 seconds.
Step 4: Release Home, and your screen should stay completely black. If so, chances are you successfully entered into DFU mode.
Notes: If iTunes is configured to do so, iTunes will open and report that: “iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes.” If your screen is black and iTunes reports this message, this is a surefire indicator that you are successfully in DFU mode.
To kick your device out of DFU mode, simply hold Home + Power for 10 seconds and release. The Apple logo should then appear.
