IPhone – Jammed lock screen button

I have the same problem with my iPod touch. In settings, go to "General">"Accessibility" and turn AssistiveTouch on. You will have a little square with a circle appear on your screen. tap that to open it up, and there will be a lock screen button. Press and hold this, and just like with the lock button, the "slide to power off" will appear. Good Luck!

Of course now you cannot power it back on as you have no power button... I had the same problem... Just connect the iPhone to your charger and it will power the phone back on.

This happened to me too. My son forgot his password, and he didn't want his iPhone anymore, but I wanted to erase the device before selling/recycling it.

The broken power button (also called the "sleep/wake" button) makes this difficult - normally you'd hold down the power & home buttons simultaneously while connected to iTunes via USB, all the way through a power cycle, through the apple logo's appearance, until it shows you the Recovery Mode screen as shown here: https://support.apple.com/en-us/HT201412

Without a working power button, a variation is necessary. What I did was use the Assistive Touch feature, which my son had already turned on months before, since the power button wasn't working. Plug the device into a computer with iTunes loaded. Hold down the "Lock Screen" button (in the "Device" submenu) for a few seconds until the power-off slider is shown. Then, while holding down the Home button, slide the power-off slider to the right - keep holding the Home button for a long time, through the device powering off, through the Apple logo, and until the Recovery Mode screen appears.

Now follow the prompts in iTunes on the computer, and the device should reset as normal.
