[Detailed Guide]How to Put iPhone 8/iPhone X in DFU Mode
Unlike putting iPhone in Recovery Mode, which enables you to re-install your iOS operating system, putting iPhone in DFU mode makes it possible for you to change your operating system. That's why when you need to downgrade your iOS version, it's necessary for you to put your iPhone in DFU mode. If you are using an iOS version with bugs you can't put up with, you may want to downgrade it to the previous version when there is no improved iOS system available. Thus this article is written to detail the method to put iPhone 8, iPhone 8 Plus or iPhone X in DFU mode. The ways to put iPhone 7 and iPhone 6 in DFU mode are also provided in case you need them. Read on to get more details.
How to put iPhone in DFU mode
To make sure the process goes smoothly, you'd better equip your computer with the latest version of iTunes. What's more, putting your iPhone in DFU mode will erase your iPhone data. To avoid data loss, you are recommended to back up your iPhone to the computer first before your iPhone enters DFU mode. Last but not least, since it's very easy to make mistake during the process, you may need to go over the steps first before you perform the method on your iPhone.

Step 1: Connect your iPhone 8/iPhone 8 Plus/X to your computer and lauch iTunes.
Step 2: Press and quickly release the Volume Up button, press and quickly release the Volume Down button and then press and hold the Side button (Sleep/Wake button) until you get a black iPhone screen.
Step 3: When your iPhone screen goes black, release Side button only and then quickly press and hold both Side and Volume Down Buttons for 5 seconds.
Step 4: Then release Side button only and hold the Volume Down button for another 5 seconds.
Step 5: During the process, pay close attention to iTunes. When you see a small window in iTunes telling you iTunes has detected an iPhone in recovery mode, release the Volume Down button and check your iPhone screen. If it's black, fortunately, you have put your iPhone 8/8 Plus/X in DFU mode successfully. While if it's not, for example, it's the "connect to iTunes" screen, you have to repeat the steps above to enter DFU mode again.
