The ZIF cable locks are the little grey pieces seen on the cable-side ends of the white bar. They will slide, as per detailed picture, toward the cable.

Step 10
Sometimes the "tags"/"lugs" that are around the edge of the top & bottom frame, be careful not to bend them as when putting back the covers they will not merge. I used a screwdriver to poke through the hole the screw was supposed go in & push against the "inside nut" to let the tag from the top slide down between the 2 tags. The "inside nut" is like the one right next to the ribbon cable as shown in Dia.14. The screws are from Dia. 7&8.
