Ok none of you faggots ever believe me but here it is. Quest 2 without Facebook. 

I have had an Oculus account from the Rift days I never linked to a Facebook account. Should be the same for new ones.

1 purge any Oculus app from your phone if installed before

2 disabled app auto updates on Google play settings

3 download the old Oculus app ver 36.0.0.5.242 https://www.apkmirror.com/apk/facebook-technologies-llc/oculus-2/oculus-2-36-0-0-5-242-release/oculus-36-0-0-5-242-android-apk-download/

4 Sign into the app with your Oculus account and leave it on

5 factory reset the quest 2 even if you just pulled it out of the box. (Volume down + power till it restarts and goes to a boot menu)

6 go through the setup as directed up to completing the wifi setup.

7 in the phone app add a headset. You won't see Quest 2 since it's an old app but select Quest option. It will likely say it faild even though it found the headset. You can back out and see it in your device list.

8 finish in headset setup.

9 eneble developer mode (google that)

10 you can now enable app updates again.

You will get warnings when downloading/buying games and apps that your headset isn't set up yet but you can ignore that. Obviously any Facebook related social functions will not work.

Some time next year you shouldn't have to jump through these hoops as playing Facebook free will be officially supported as announced by the zuck earlier if you trust that.
