Kudos to everyone who warned about the screws in step #8. They’re not nice screws and they do need to replaced with a reasonable amount of torque in order to secure the BlueTooth/WiFi assembly. You have to remove those screws in order to remove one of the 3 Torx screws securing the drive mechanism.
I personally had little trouble with the screws in step #8 but only because I was forewarned and took extra care to ensure that I was using the exact cross head driver for the screws. It helps to have the right tools.
Now… if anyone has any tips on how to get those fiddly Torx screws back into their positions I’d be even more grateful. I’ve managed it but find that screws like that are a real pain to get back into place. The heads are not at all deep, they’ve picked up a bit of magnetism and prefer to jump off the driver and stick to any other metal in the machine. The longest part of the job is getting those three screws properly seated (not cross threaded) and screwed down to the point when the drive is secure.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
