If your iPhone Duo bugs out or stops responding and you can't turn it off and back on again, you can try something called a force restart. The process involves pressing the two volume buttons in sequence, then holding the side button until the Apple logo appears.
The iPhone Duo's volume buttons can change function depending on how you hold the device, so to make it easier for you, in the following steps we will identify them by their physical location. Keep reading to learn how it's done.
How to Hard Reset iPhone Duo
- Quickly press and release the volume button nearest the side button.
- Quickly press and release the other volume button.
- Press and hold the side button until the Apple logo appears, then release the side button.
The order in which you press the volume buttons matters, so start with the one nearest the side button, then press the other. Both presses should be quick, and you only need to keep holding the side button at the final step.
If your iPhone is responding normally and you simply want to turn it off, swipe down from the top-right of the screen to invoke the Control Center, then long press the power button in the corner until the shutdown slider appears. To turn the device back on, just press and hold the side button until the Apple logo appears.
