HTC Vive Focus Motherboard Replacement

Introduction

Follow this guide to remove or replace the motherboard on a HTC Vive Focus.

Power down your device before you begin. Be careful not to power on your device while making repairs. If you accidentally power on your device, stop working and power it back off before you resume.

This repair requires breaking the plastic welds that help secure the front cover to the device. If you complete this repair, the gaps between the plastic front cover and side panels will no longer be flush. This damage is permanent but only cosmetic and will not affect the device’s functionality, usability, or operation.

Does anyone know where to get replacement flex cables for the focus plus? I have been given one to repair but the power button flex was torn and is beyond repair.

Thanks
