I skipped 6, 8 and 11. Works fine just means you have to be more careful moving things around as opposed to being more careful disconnection (and reconnecting cables).
TIP: If you do not have wifi and bluetooth after completing the the upgrade don't panic and stay calm. Assuming you were careful during the procedure you may have disconnected the airport/bluetooth board from the logic board. Without taking the airport board apart it looks like there is only one connection on the ribbon cable, on the logic board side. However there is another connector under the black material on the airport board side. Simply press your finger on the airport board right beside where yhe ribbon meets the airport board. If you hear a click you may have just solved your problem.
Great guide! Made it relatively easy to perform the upgrade. I did skip steps 6,8 and 11. Skipping steps means being more careful not to stress cables, connector or boards when maneuvering things around. Most connectors are pretty simple, just about weighing the odds of breaking a part by trying to remove/reconnect things or by working around the connections. Like every repair be diligent and take your time. It takes much less time to read and look closely at the steps then to order and reinstall another part.
