The front glass panel was cracked.
The repair went off without a hitch.
Do not try to pry from the sides, only the corners.
Use your jimmy to pry the glass just enough to fit an opening pick in the gap, then use those to slice down the length of the adhesive and hold the edges off the frame.
Your suction cup will not be very useful without a clean un-cracked portion of glass to attach it too. If you have a spot for it, it will allow you to apply upward prying force from both sides of the glass, using the opening picks and the suction cup. Remember to move the suction cup along with your pry tools.
