Meta released a web tool letting you force update your Quest headset to the latest system software version.
The new Meta Quest Software Update Tool is a webpage that uses the WebUSB API to sideload the latest update to your USB-connected Quest headset.
WebUSB works on Windows, Mac, Linux, ChromeOS, and even Android via Chromium browsers such as Google Chrome, Microsoft Edge, Opera, and Samsung Internet. You can access this tool by signing in with Meta.com and setting the country to US. If you are using a Mac, you will need to switch to another browser. To be clear, this does not mean you must have a US-based account. You simply need to change the region of your site to United States. Hold down both the volume up and down buttons until you see the Meta logo, then let go. You select Sideload update using the volume controls. This will not reset your headset and will keep your files, apps and data. Meta releases sub-updates that are dynamically rolled out by Meta servers. This includes the major Quest 3 passthrough improvement in v66.0. This includes the Quest 3 Passthrough Improvement in v66.
