How to bypass trust on broken iPhone/iPad screen
If you want to restore your iPhone/iPad with a broken screen, you can bypass the "trust" step" by putting it in "DFU" mode which is a recovery mode. To do so, connect it to your computer with a usb cable, then you have to press both home and power button for 10 seconds then release power button for 5 seconds. You'll then be able to backup/restore your device!
