OxygenOS I upgrades from Oxygen OS Beta to Hydrogen OS 10. If I factory reset, will it go back to Oxygen?

    I really wanted Android 10 so I decided to install HydrogenOS onto my 6T (From Oxygen Open Beta 17 to Hydrogen 10 Public Beta). However, I was wondering, what OS will it revert to if I factory reset?

    You've installed Hydrogen and overwritten Oxygen with that. A factory reset will give you Hydrogen again.
    You need to flash Oxygen again in order to get it back.

    How would I flash Oxygen? I've tried installing the most recent beta but it does not allow me to install as it's an older version.
