I'm going to give this a try later. One small fly in the ointment is that if like me you do not have and do not want to ever have a Facebook account, it will not be possible to load this onto the device after 2022. This is because loading the ADB requires putting the device in developer mode, which in turn requires an internet connection and an active login to your Oculus developer account. Oculus developer accounts…
You sure? “In part, the unlocking is an attempt to guarantee that Go hardware will continue to be fully functional well into the future, allowing for "a randomly discovered shrink wrapped headset twenty years from now [to] be able to update to the final software version, long after over-the-air update servers have been shut down," Carmack wrote.”
The whole process for putting an Oculus device in developer mode is incredibly fiddly and annoying. You need a verified developer account. You an app running on a phone, which in turn requires an online login. You can't just do it from a desktop PC and you certainly can't flip a toggle on the device itself.
Ideally, as a follow-up to this, they will release something that allows putting the device into developer mode without requiring any of that. As of now, that does not exist.
