Facts: How Much Do You Know about DFU Mode?

What is DFU Mode?

DFU Mode allows users to put iPhone/iPad into where it can interface with iTunes but does not load

the iPhone operating system or boot loader. That enables users to alter and select the desired

firmware to install onto iOS device. For instance, you would use DFU mode if you want to re-install

a previous version of iOS, jailbreak your iPhone or unlock your SIM. Compared with Recovery

Mode, DFU Mode is for dealing with systematic issues, like updating/downgrading, jailbreaking and

other while Recovery Mode is for data restoration and software update.

DFU Mode comes in handy when you're under the following situations:

1. Fail to access iPhone/iPad, such as iPhone/iPad is stuck in Apple Logo screen, iPhone/iPad

cannot stop rebooting, iPhone/iPad becomes unresponsive and so on. In these cases, you should try

enter the Recovery Mode at first. If it fails, DFU Mode is the second choice. (iOS System Recovery

is also recommended.)

2. Try to jailbreak iPhone/iPad or unlock SIM card. During the process of jailbreaking and SIM

unlocking, users will need to get access to DFU Mode in order to continue the process.

3. Want to downgrade iOS on iPhone/iPad. Most iPhone 6 users report that iOS 10 causes many

problems on the device, so they'd like to have it downgraded. Note that Recovery Mode can't

downgrade iOS.

Tutorial: How to Enter DFU Mode on iPhone/iPad?

Make sure that you've installed the latest version of iTunes, and then follow the following steps to

get your iPhone/iPad into DFU Mode.

For users who are using models latter than iPhone 7/7 Plus:

Step 1. Plug your iPhone/iPad into the computer with a USB cable.

Step 2. Power off the device.

Step 3. Press and hold the "Power" button for 3 seconds.

Step 4. Press and hold the "Home" and "Power" buttons for 10 seconds.

Step 5. Release the "Power" button but keep holding down the "Home" button.

After about 15 seconds you will be prompted by iTunes saying that it has detected a device in

Recovery Mode.

For an iPhone 7/7 Plus users:

Step 1. Connect iPhone 7/7 Plus via USB cable to the iTunes on computer.

Step 2. Turn off the device.

Step 3. Press and hold down the "Power" button for three seconds.

Step 4. Hold the "Power" button and "Volume Down" button together for 10 seconds.

Step 5. Release the Power" button but keep pressing the "Volume Down" button until it prompts that

your iPhone is in Recovery Mode.

It seems a bit complicated to enter DFU Mode, right? However, it cannot be easier to exit the DFU

Mode on your iPhone/iPad.

Press and hold down the "Home" and "Power" buttons at the same time until the Apple Logo appears.

The steps are exactly as same as the way you hard restart the iOS device.

iPhone/iPad frozen in DFU Mode when trying to jailbreak/downgrade the device. Though these are

rare cases, you should know how to deal with this situation in case that it comes to you one day.

iOS System Recovery, as its name tells, is a professional tool developed to address a variety of iOS

your iPhone/iPad via USB cable to it. Select "More Tools", and then choose "iOS System Recovery"

option. Hit the "Start" button to continue.

Note that there is also an advanced Mode available. However, it would wipe out all your data in

order to fix your device back to normal, so use it only if the normal mode fails.
