do not pry up! pull to one side so you don't disconnect the clip from the motherboard!

Actually Lisa, you are incorrect. If you pull to one side you WILL end up pulling the connector off the motherboard. It is designed so that you ARE MEANT TO pry it upwards out of the connector. All you need to do is use the point or corner of the flat edge of a spudger (or a small flat-headed screwdriver), push it ever so slightly under the middle of the small white plug where there is a small recess in the connector for just this purpose. Prying the plug up in this fashion you should clear the connector with the spudger by prying it up through the recess rather than catching the connector and pulling it off the board.

When I was putting mine back together, the flap popped off and when I tried to put it on with a tweezers, it snapped. Any suggestions other than scrap it or use it without the touchscreen? Pictures at https://sites.google.com/site/memesbyluc...
