Great guide, covers the details nicely. I would add that the nvram command no longer works as of firmware in Big Sur. We don’t have too much trouble with that, however. Shut down the machine, and make sure to not open the lid or do anything else until the battery is disconnected.

I will also note that we’ve never had a T3 screwdriver not strip unless we cut the tip off the torx; the screws Apple uses never seem to be happy until that is done. Haven’t see anyone else complain about that, though, so maybe it’s just us!

In case anyone is wondering: as long as your part is OEM, it shouldn’t give any issues with the T2 chip. Most assemblies are not sold with the screen angle sensor, however, so that needs to be transferred to the new assembly. That’s just a matter of unscrewing the one screw that holds it to the clutch and then attaching it to the new one in the same way.
