Yes, there is a screw holding down the fan shroud it is an angled black part where the guy's left hand index finger is located in Step 56

Think that a screw part uninstall was missing, it will hold the motherboard in, until you remove it. Located at the bottom of the hard drive bracket, Requires a T20 to remove it. Then the motherboard come out easily as the instructions state. I'd post a photo, but can't on this comment section. My Mod for a customer, is to remove the "fusion", replace that PCIe "blade" with a 2TB from OWC. Reformat the internal 1TB hard drive to be used as extra storage or backup. The screw could have been referred to as : One 20.1 mm T25 spacer screw, mine was a T20. Perhaps there are some differences in models.

Would be good data to show the 3 areas (wifi antennas where the "tape" is larger and covers them. The rest of the "tape" is 1.4" and easy. Also after removing the display, be sure to remove the old "tape" from both the display and the rubber parts of the case. Use the spudger to start an end and it should pull off easily. Careful on the baackside of the display as you can scratch off the black paint/covering.

You can "warm up" the adhesive before try to cut it with the tool using a hair dryer. Heat the edges for about a minute, keep moving it so you don't cause stress in the glass. Also the above note.. use the tool and then the cards. Do not use a guitar pick or other objects as the thickness will cause you to break the front glass, which is a bonded part of the display (expensive).

Update on logic board alignment - use two USB plugs one in each end of the connectors through the back to be sure alignment is good before tightening screws.

The newer drives have rubber ends and an adhesive side, be careful removing them if replacing the drive and be sure they are securely pushed back into the holder

OK, so when did you remove the RIGHT speaker? Suddenly it is not in the photos. I s there anything besides it's plug to remove?

Very difficult. be very careful on the limited space end that you don't puncture the battery!

Strongly suggest you remove the display. Also the picture shows the "perfect world" it is far ore difficult to remove and get to those white adhesive pull strips. be very careful!!!

If you push 1, then 2, then the side button and the slide appears, keep the button down and click on the X (cancel) button, then the logo will appear. Now it has reset!
