Reheat your iOpener and apply it to the top edge of the device for at least 2 minutes.

Insert an opening pick or a halberd spudger just past the front-facing camera.

Use your cutting tool to slice the remaining adhesive underneath the top edge of your device.

Don't insert your slicing tool deeper than 2 mm, or you risk permanently damaging the display panel.

If the slicing becomes hard, reheat the edge and try again.
