This guide is grossly incomplete. Do NOT try to pull up the sensor array after taking these five screws off. There are 8 more screws that have to be removed, as well as 2 tabs that need to be pushed before the sensor array comes off.
-Two screws on the bottom (by the camera) to each side. There are four screws here, but only the outermost two need to be taken off. See the two sensors on the bottom? The screws under the outside corner of each sensor are the ones you remove.
-Two screws on the top, to the right and left of the cable opening.
-Four screws on the back, to the left and right of the lenses. Turn the Vive around, the screws are deep inside four holes.
-Finally, two tabs on the bottom by the camera. If you look closely you will see them!
