I followed the steps regarding removing the display glass, since my old one needed replacing. Unfortunately it did not come off, even with a good amount of heat from a heat gun. I felt any more heat would start to melt things. Eventually I tried prying a corner, which caused a crack, and ultimately I ended up chipping out tiny shards of glass everywhere. Eventually I got it done, but it was a royal pain. BE CAREFUL AND WEAR SAFETY GLASSES.
