• Alternatively, use strong tape instead of the suction handle.
• As a last resort, superglue the suction handle to the broken rear glass.

Pull up on the suction handle with strong, steady force to create a gap between the glass and frame.

• If creating a gap is difficult, apply more heat to further soften the adhesive.
