Next we will remove the bottom plate. The alcantara is glued on a plastic frame. You don't need to remove the alcantara.

Start at the connector side. Use your hairdryer / heatgun to weaken the glue. Cut between the frame and the alcantara. Don't tilt your opening tool. 'Save' your progress with the opening picks.

The keyboard an the back plate is separated with a white plasic foil. Try to keep it on the keyboard side. See those 3 stripes of glue? That's where it's attached to plastic frame. The connection can be unstuck with heat and your opening tool.

Move to the next step before reaching the trackpad side.
