dsi bottom screen parts

If you look at the bottom screen assembly from the side you'll see the metal part (the lcd screen) and the transparent plastic part (the touch screen). You can separate the two by using a flat blade xacto knife and running it around the edges of the assembly where the adhesive is. Then simply reuse whichever part is still good.

Reassembly is the reverse of removal.
