Would have been better if the repair had been done on camera!! Some of the removals were off screen and the start where the hinged unit was removed, what was going on there? Still images may have been a a help,

As with dismantling anything, it's best to set them out as you taken them off in some sort of reference grid. Or at the very least a photo of what you took off so when you come to that last weird screw that doesn't seem to belong anywhere, all you need do is back track your photos or look at where it came from and where it was left on your reference grid when you took it off.

It pays to prepare, I have a drawer full of "extra" screws, left over prior to finally slowing down and noting where I was putting things and from where they had just been removed.

I would have to say a partial disassembly, unless I'm missing pages somewhere?
