All documentation followed by Tai.

 

1. Official Onion OS: https://github.com/OnionUI/Onion/wiki/Installation

Only install Onion OS v.4.0.4 or later for firmware versions starting with 20221216 or 20221224

I followed the "Installing (on an empty SD card)" instructions since I wanted to use my bigger 256GB Samsung MicroSD card.
