There is NO NEED to remove the screen. There is multiple guides on here and the one I read before didnt take it off. I didnt know I had the wrong guide till after I took it off. I spent 30 mins just trying to get those 3 screws back in.

IMO, gently holding the screen you can remove the batter, saving the extra time it took me to reassemble the screen twice, since it had white lines.
