Hey there. Just opened my evo for the first time yesterday. I wont mention the method that I used because it left little jagged edges in my plastic frame. I would try again with a plastic "safe-pry" tool, just like the green ones you posted. It takes considerably more force than I had expected after removing the torx screws, both to remove the backing (pictured in your post) and to remove the screen (this is what I was up to - cracked glass replacement). "A bit of adhesive" is what I was told holds the glass into the plastic frame... understatement of the year with my Evo. I really had to work at it. Again, the tool I used jacked me up a little, so I would not reccommend using anything other than something plastic that can slide in between the separation of the frame and whatever you are trying to remove. Good luck!
