There is a major problem with the information provided here.
I followed the advice of the staff and purchased on eBay a replacement glass with tools for our cracked glass problem. I then began to follow the guide shown here.
The first major problem is that the suction cup will not pull off the glass. I tried the suction on various surfaces, and it's very strong. So no doubt, the problem is the fact that the glass is cracked. But that's the whole reason we're trying to take it apart. Secondly, if this guide doesn't apply to cracked glass, that should be clearly stated and possible another guide should be provided.
As it is now, removing the "glass" from the foamy "gasket" underneath was nearly impossible, and the local tech now tells me that in this condition, it's essentially worthless.
