Thanks for this fantastic guide!!! Got an old Macbook Air working again. Only difficult spot was the ZIF cables. Man, I hate ZIF cables....

Ok finally got the cable and was able to successfully finish the project.

That video cable is ROUGH to install.

Same problem for me. I damaged this cable and am ordering one now.

This is a tough step so I would also suggest removing this cable first.

I had the same problem but only on one of the two screws. Then I realized there's a little tiny "o-ring" underneath which is acting like a nut. I lost one of them in the process of upgrading. If I could find out where to buy a new one I would!
