Use a hair dryer or heat gun to soften the adhesive holding the display assembly to the frame.

Heat one side of the device, then insert opening picks between the digitizer and the frame to separate the adhesive.

Heat one side of the device at a time to ensure that the adhesive stays soft.

If your screen is severely cracked, use a suction cup to pull the display assembly up.

Be careful to not bend the metal tabs in these areas.
