iPhone How-To Guide • RecoveryRecovery mode didn't work? DFU mode is the next step. It takes careful timing, so read all the steps before you start.
Works on: iPhone 8, 8 Plus, SE (2nd and 3rd generation), and every Face ID iPhone from iPhone X through iPhone 18 Pro Max.
Warning: A DFU Restore Erases Everything
This deletes everything on the phone. Use it only as a last resort, after recovery mode and iOS Recovery fail. Photos, messages and apps are gone unless you have a backup (see How To Back Up Your iPhone). If you want to keep your data, call or text (720) 413-8150 first.
How To Enter DFU Mode
The screen stays black in DFU mode. That is normal. If you see the Apple logo or the computer-and-cable picture, you held a button too long. Start over.
- Plug the phone into a Mac (Finder) or a PC (Apple Devices app).
- Press volume up and let go right away.
- Press volume down and let go right away.
- Press and hold the side button until the screen goes black, about 10 seconds.
- Keep holding the side button and also hold volume down for 5 seconds.
- Let go of the side button but keep holding volume down for about 10 more seconds.
- The computer should say it found an iPhone in recovery mode, while the phone screen stays black. This is the last step: click Restore. This deletes everything on the phone.
Did It Work?
DFU restore failed too? It may be hardware. I can check it and refer board-level work to a microsoldering specialist.

Changed your mind? A force restart takes the phone out of DFU mode without erasing it.
Apple doesn't publish DFU steps. These timings are the ones repair techs use.
