Same here, so suspect I have the same problem, didn't see these comments until after I finished!

Took me nearly 2 hours to remove the glass because it just shattered even more every time I used the sucker. Used IsoPropanol to clean.

Checked all was working with the new digitiser and home button by starting iPad before sealing the glass shut, all ok.

Stuck it all down, home button works occasionally, but also siri bleeps on it's own sometimes as if someones pressing the button. Also, if I press either side of the home button I get a reaction as if I've pressed the home button, or sometimes I get the double tap action and sometimes Siri, makes me think that there is something shorting / touching that shouldn't be, unless it's the ribbon.

Will order another kit and give it another go shortly as the glass is sure to break when you re-open.
