Hi NetRunner_2k77β π
The easiest way might be using an iphone, if you have one or if you can borrow one.
For Android you'll need an older version of the phone app to pair the Quest 1.
The following solution explains what you must do and includes a link to an older version..... maybe you must try multiple version numbers though.

The app will probably tell you to update.... you must skip that.
Unfortunately, on some phones the skip button isn't visible and can't be used. π
If thats the case, use a tablet for the set up.
A friend set up a Quest 1 recently with an Android tablet using version 257.0.0.16.106 - the next/continue buttons here were also almost hidden at bottom of the page, but he could use them..
Good luckπ€
