woked for me, using crucial CT1286AC800 M8FJ18

(1gb 200pin DDR2 Sodimm 128Mx64)

step 8, with no cell radio this is not needed (as mentioned)

step 24, with SSD no need to remove daughter board, can pivot MB on cable and insert memory (as mentioned)

step 25, hinge bracket, dont need to completely remove screws, the hinge has a part that is above the MB, can just losen and slide MD down

when reinserting the cables with the locking arms, SSD/keyboard/trackpad, make sure fully home, can be quite hard to tell due to the still/short cables. (experience from other stuff.)
