Except for (cosmic-) bitflips and/or evolution changing the programming

That its producer has gone bancrupt they have absolutely lived the enshittyfication while doing the settings in their custom Android and I am currently on the last supported android version (12) which will probably go unsupported soon-ish and the company I got the phone from has sold so few that the definitely better alternatives (Lineage, etc) don’t have any reports of people who have done it with my device or even a tutorial. And reading into flashing it on an unsupported device is a rabbithole I currently don’t want to spend time with. And if I fuck up I can’t even write the company to fix it for me or smth like that…
