Hi raldone01 🙂
Use another phone or a tablet to pair the Quest.
Pairing the Quest 1 does not work on an Android phone with the current Meta Horizon version anyways.
The easiest way is using an iphone - maybe you can borrow one for a few minutes - on iphones the setup works without issues.
On Android phones setting up the Quest 1 only works when you use an older version of the Horizon app.
The solution in the link below decribes what you must do. Unfortunately, the link to the old version doesn't work anymore. I'll put in a link where you can download old versions.😉

The app will tell you to update - you must skip that. Unfortunately, the scaling of the (old) app doesn't fit most phone screens and the continue/skip button is not visible. If that's the case, use a tablet for the setup. Even here the button is only partially visible at the bottom, but you should be able to use it.
212.0.0.2.109 worked some time ago. I'm not sure, if it still does. You might have to try multiple ones. The number gives you at least an idea where to look🙃
And as Maccyb123 said, edit your post and remove the serial number... also on the screenshot.
