I suggest opening it laying with front upside, that way you minimize the danger of losing the springs and also the battery hinges stay in place.

Also you can pull off the whole sticker, but they used a pretty glue. It even still held well after I was done with the reassembly.

The bottom one is a long one, don't forget as later you will meet also longer ones.

Happened to me, had no clue where it was supposed to go XD

Upper comment is correct, they are about a cm to the outer sides of the circles. The circled ones on top are blind, the board has no holes there. Maybe a prototype still had them?

Also all those four screws are long ones. The fifth long one you should have unscrewed already was the one under the sticker in the bottom middle.

I don't agree, I think it's the upper shoulder buttons, which I just have to fix. It's just a small plastic-part with a thin bridge used as a spring-like, so an obvious breakpoint.

The other one was also already cracked. I just superglued them back now, seems to work, how long is the question though.

Otherwise I've seen there's also 3D-printing manuals on thingiverse, next time I will try printing them myself, maybe with a thicker bridge then.

Just for posteriority, because I also forget to check it and had to figure our in hindsight.

The first seven are 6 small ones and a long one in the middle under the sticker.

The next four long ones are what holds the board to the upper part, two are at the top near the shoulder buttons on the inside, and the other two are left and right at the bottom, they are also part of the battery holding cases.

The rest are small ones, but I didn't remove the ones holding the touchpads so I can't say for sure.

Just for posteriority, this is what I just fixed on mine. It's just a small plastic-part with a thin bridge used as a spring-like, so an obvious breakpoint.

Guess it's just to ground it then as the other guy said it's both on zero.
