FYI: Under Step 13, you missed 1 ribbon cable that also needs to be detached in order for the motherboard to be separated. It is the tiny IC housed in a small PCB near the bottom left of the C-Stick. In fact, this little ribbon gets separated and reattached throughout your guide pictures starting with step 8. Here is a link to the ribbon in question (Note: Pic borrwed from Step 12 which highlights the red cable. Look for my lighter arrow which shows the missing ribbon): http://i.imgur.com/0V7QI4i.jpg
