I tried to replace the glass on my wife's IPAD but it was already very shattered. At one point when I attempted to suction cup an edge, the glass really shattered and I guess shattered the LCD panel as well when I didn't notice it. The glass panel went back on very well. But because the LCD panel was now shattered, the unit looked great but wasn't working. Great experience, but if the glass is shattered as my was, it's unlikely you will be able to repair the unit.
