Grab the lifted portion of the home button assembly and gently pull it away from the display, tearing the rest of the adhesive.

As you pull the assembly away, the rubber backing may begin to separate from the home button. The home button is only connected to the rubber backing by a fragile cable, so do your best to keep them together as you pull the assembly out.

If you are transferring your home button to a new display, the original adhesive should be strong enough to keep it in place.

If the original adhesive is not strong enough to hold the button in place while you re-install the display, you can lay the button in the chassis, and then install the display over it—the display assembly will keep the button in place.

If you are installing a new home button, remove the plastic film covering the adhesive, then carefully align the button with the display and press it into place.
