Insert the pry tool along the side of the device, then work your way around the borders of the screen, separating the screen from the rear assembly frame.

Be careful and do not lift the screen completely off yet, leave the screen at an angle.

Use the heat gun to heat up the bottom to loosen the adhesive from the menu and back buttons.

Once heated, gently pull the screen upward.

Make sure that the buttons are separating from the adhesive.
