Hi @Twisty welcome to /e/ land.

Is critical - @OneThumb provided this clue recently: [GSI] Q-GSI --- new version download location. See post 73 - #109 by OneThumb

Please be aware that anything which involves “a backup of your EFS partition” requires careful thought, reading and preparation.

This is the /e/ documentation page

Bon chance
