How To keep An iPhone In to DFU Mode ?

Hi friends, in this topic I am discussing How To Put An iPhone In DFU Mode ( Device Firmware Update).DFU is the deepest type of restore you can do on an iPhone.
 

A lot of the information out there is just plain wrong. In this article, I’ll explain what DFU mode is, how firmware works on your iPhone, and show you step-by-step how to DFU restore your iPhone.
 

What You Need To Know Before We Start.

• The Home Button is the circular button below your iPhone’s display.
• The Sleep / Wake Button is Apple’s name for the power button.
• You’ll need a timer to count to 8 seconds (or you can do it in your head).
• If you can, back up your iPhone to iCloud or iTunes.
 

 

How To Keep An iPhone In DFU Mode

• Plug your iPhone into your computer and open iTunes. It doesn’t matter if your iPhone is on or off.
• Press and hold the Sleep / Wake Button and Home Button (iPhone 6s and below) or the volume down button (iPhone 7) together for 8 seconds.
• After 8 seconds, release the Sleep / Wake Button but continue to hold the Home Button (iPhone 6s and below) or the volume down button (iPhone 7) until iTunes says “iTunes has detected an iPhone in recovery mode.”iTunes has detected an iPhone in recovery mode
• Let go of the Home Button or volume down button. Your iPhone’s display will be completely black if you’ve successfully entered DFU mode. If it’s not, try again from the beginning.
• Restore your iPhone using iTunes.

 

How To Keep An iPhone 8, 8 Plus, Or iPhone-X In DFU Mode

A lot of other websites give false, misleading, or overcomplicated steps when telling you how to DFU restore your iPhone 8, 8 Plus, or iPhone-X. They’ll tell you to turn off your iPhone first, which is completely unnecessary. Your iPhone does not have to be off before you put it in DFU Mode.

If you like our videos, watch our new YouTube video about how to DFU restore your iPhone X, 8, or 8 Plus. If you prefer to read the steps, the process is actually a lot easier than they make it out to be! The process starts off just like a hard reset.

• To DFU restore your iPhone X, 8, or 8 Plus, quickly press and release the Volume Up button, then quickly press and release the volume down button, and then press and hold the side button until the screen goes black.
• As soon as the screen turns black, press and hold the volume down button while continuing to hold the side button.
• After 5 seconds, release the side button but continue to hold the volume down button until your iPhone shows up in iTunes.
• As soon as it appears in iTunes, release the volume button. Ta-da! Your iPhone is in DFU mode.

Note: If the Apple logo is appearing on the screen, you held down the volume down button for too long. Start the process over from the beginning and try again.
 

A Word Of Warning

If your iPhone is damaged in any way, and especially if it’s water-damaged, a DFU restore may break your iPhone. I’ve worked with customers who tried to restore their iPhones to fix a minor problem, but water had damaged another component that prevented the restore from completing. A useable iPhone with minor problems can become completely unusable if a DFU restores fails because of water damage.

When you DFU restore your iPhone, your computer erases and reloads every bit of code that controls the software and hardware on your iPhone. There’s the potential for something to go wrong.

 

What Other Electronic Devices Have Firmware?

All of them! Think about it: Your dryer, washing machine, microwave and TV remote all use firmware to control buttons, timers, and other basic functions. You can’t change what the Popcorn setting does on your microwave, so it’s not software — it’s firmware.

 

What’s Firmware? What Does It Do?

Firmware is the programming that controls the hardware of your device. Software changes all the time (you install apps and download new email), hardware never changes (hopefully, you don’t open your iPhone and rearrange its components), and firmware almost never changes – unless it has to.

 

DFU Restores All Day, Every Day.

Apple employees restore a lot of iPhones. Given the option, I’d always choose a DFU to restore over a regular or recovery mode restore. This isn’t official Apple policy and some techs would say it’s overkill, but if an iPhone has a problem that can be resolved with a restore, a DFU restore stands the best chance of fixing it.

Thanks for reading and I hope this article clarifies some of the misinformation on the internet about how to enter DFU mode and why you’d want to use it. I encourage you to embrace your inner geekiness. You should be proud! Now you can tell your friends (and kids), “Yeah, I know how to DFU restore my iPhone.”
