Hi there, SchwarzeRose and welcome to the community forums!
I understand you are having issues with the update? Have you tried the troubleshooting checks supplied by Meta Quest Support on Page 1? I'll copy them here for you so you can see them more easily:
- Ensure that you have enough storage space in your Quest headset, as sometimes the Software Updates can be substantial in size and may require enough space in your Quest Device.
- Try a different supported browser, Chrome, Edge, and or Opera
- Remove Elite Strap with Battery or any third-party accessories from the headset. If you are using an Elite Strap with Battery or other headset accessories please remove it from the headset before attempting to connect the headset to the computer.
- Check USB connection. Ensure that you are using a high-quality USB-C cable capable of data transfer for connecting your Meta Quest headset to the computer. The cable provided with your headset will suffice.
- Confirm headset software version. Prior to updating your headset manually, verify that it is running the appropriate software. To find the current build number in the headset, navigate to Settings > System > Software Update. It is possible that your device already has the latest version installed.
- Try another computer and cable. In the event that none of these steps resolve the issue, attempt connecting your Meta Quest headset to a different computer or try a different USB-C cable that can support data to determine whether the problem is related to the headset itself, the original computer, or the USB connection.
In terms of the spacing, yes, 70mm would be the maximum pupillary distance you can adjust to so this would be correct.
Hope this helps! Let me know if you're still experiencing issues with the update and we can work through further checks together 😁
