    5. Now use the pick to push the display toward the Lightning connector so the tabs come out of the aluminum frame.
    6. Rest the display on the aluminum frame, so you don’t overstretch the flex cables.

    If necessary, heat the outer edges of the display a few times. Don’t forget that the flex cables for the display are on the side with the Sleep/Wake button. The display is also engaged at the edge of the earpiece.
