In the documentation after “Installing /e/OS from recovery” you reboot into recovery mode and then work in TWRP. In recovery mode I can’t find TWRP, so I do not know how to go on in the documentation. Do I have to install TWRP according to LOS (not mentioned in the documentation)?
To answer my question: Do I have to raise an issue? If yes: In the BQ category?
