See https://www.youtube.com/watch?v=kmN_pDAF... for his technique to remove ribbon.
I have the Asus S 8 and it too has a cracked screen. I found this video on youtube.com where a guy replaces the glass screen on an Asus Transformer. He does mention two "ribbons" inside with numbers on them and says you should look at that to order the right screen, Right now, I'm trying to find a seller with the right glass. The digitizer is okay, it is only the glass which is cracked, it still works.
