The old glue was full of tiny shards. I rubbed it all away with many Q-tips and petroleum ether. To protect the LCD I used a sheet of heavy paper. Cleaning took a lot of patience.

Still should have listened to Mike: The digitizer ribbon cable went between the frame and the panel. It was bent too sharply. Touch worked, but the home button did not. When i tried to reopen, the glass cracked. Big disappointment, but ill try again!
