Introduction

Prerequisite guide to disconnect the daughterboard in the HTC Vive Pro 2 headset.

Tools

Parts

Kapton Tape

Step 1

Rotate the head strap forward as far as it will go.

Step 2

Unplug the All-In-One Cable from your headset.

Step 3

Remove the All-In-One Cable from the cable guides along the left side of the head strap.
During reassembly, connect the All-In-One Cable to the headset before routing it through the cable guides. This will ensure it has the right amount of slack.

Step 4

Separate the top strap from itself where the Velcro secures it.

Step 5

Peel back the Velcro securing the rear of the top strap.
Feed the top strap out through the head strap to partially remove it.

Step 6

Feed the top strap through the clip near the front of headset to fully remove it.

Step 7

Peel off both front side foam pads to uncover the speaker wires.

Step 8

Use the point of your spudger to pry out the two rubber spacers next to the headphone screws.
Be careful not to accidentally pry any of the speaker wires under the rubber spacer.

Step 9

Use the point of your spudger to pry up and disconnect both the left and right headphone speaker wires.

Step 10

Use a T6 Torx screwdriver to remove the two 12.1 mm screws (one on each side) securing the head strap to the headset.
Use a T5 Torx screwdriver to remove the following screws securing the head strap to the headset:
Four 3.9 mm screws (two on each side)
Two 4.1 mm screws (one on each side)

You do not need to remove the four 3.9mm screws or the 4.1mm screw. They do not secure the strap to the headset. You only need to remove the two 12.1mm screws.

Step 11

Remove the two plastic spacers underneath the previously removed Torx T6 screw.

Step 12

Thread the headphone speaker wires out through both ends of the head strap.

Step 13

The four screws securing the outer shell are covered with black stickers. If the stickers are difficult to remove, simply press your T6 Torx driver through them.

Step 14

Use a T6 Torx screwdriver to remove the four 3.9 mm screws (two on top, two on bottom) securing the outer shell to the headset.

Step 15

Insert an opening pick into the seam between the two halves of the outer shell.
Slide the opening pick through the seam to dislodge the clips securing it to the headset.
Only insert the opening pick as far as necessary. There are ribbon cables underneath the outer shell.

Step 16

Continue sliding the opening pick through each seam until all clips have been dislodged.

Step 17

Carefully slide each half of the outer shell off of the sensor array.
Be careful not to snag any of the ribbon cables underneath.

Step 18

Use your fingers to gently peel the face rest cushion off of the headset.

Step 19

Use the point of your spudger, or a clean fingernail, to flip up the locking tab on the microphone ZIF connector on the daughterboard.

Step 20

Use tweezers, or your fingers, to pull the microphone cable straight out of its socket.

Step 21

Use tweezers, or your fingers, to peel the conductive fabric off the sensor array ZIF connector on the motherboard.

Step 22

Use your spudger, or a clean fingernail, to flip up the locking tab on the sensor array ZIF connector.

Step 23

Use your fingers to grip the left and right sides of the sensor array cable and pull it straight out of its socket.

Step 24

Use a T5 Torx screwdriver to remove the four 3.0 mm‑long screws securing the top of the sensor array.

Step 25

Use a T6 Torx screwdriver to remove the four 3.8 mm‑long screws securing the front of the sensor array.

Step 26

Lift the sensor array straight off the lens assembly and remove it, making sure you thread the cable through its slot.
During reassembly, make sure the sensor assembly cable is threaded through its slot before continuing.

Step 27

Use your fingers to peel up the thermal pad covering the daughterboard.
The thermal pad will likely remove the Kapton tape from the ZIF connectors on the daughterboard. Replace the Kapton tape if necessary.
Set aside the thermal pad. You'll reuse it during reassembly.

Step 28

Insert the flat end of a spudger under a corner of the lens assembly press connector.
Don't insert your spudger anywhere else, as you risk dislodging nearby surface-mounted components.
Twist the spudger to lift the press connector up and disconnect it.
Repeat the same process to disconnect the other lens assembly press connector.
To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Don't press down in the middle. If the connector is misaligned, the pins can bend and cause permanent damage.
