Got a cracked screen from toddler stepping on the iPad. My repair went well, everything worked. Except I scratched the LCD. It seems to scratch easily.
At this step, be careful when folding over the screen, as it may scratch on the aluminum frame (third picture). When they say “soft lint free surface” that is needed, specifically where the LCD meets the frame. Place a thin cloth like sunglass cleaning cloth over the edge of the frame.
I did this repair. I used a hair dryer, I think it works better: gets very hot fast.
