Not to be that guy but do you really trust an “unofficial port” you found on Telegram? That seems, to me, just as problematic as blindly trusting Google.
Has this port been tested for behavior that’s non-standard in LineageOS? Random ports distributed in channels such as Telegram do not instill much confidence that it’s legit and not riddled with spyware/malwnare.
I don’t have a solution for you but I’d think twice about installing any OS that isn’t distributed (or at least validated by) via official channels.
As long as your important data is safe, go mess things up. Break things, read the docs, reinstall if necessary. This is how we all learn.
I can’t count the number of times I’ve had to reinstall because I attempted a fix that made things worse. It’s not the end of the world… In fact each time you do you’ll be better at it.
When your data is safe (backed up or stored on a NAS) the reinstall stakes are a lot lower so there’s not as much pressure to keep things perfect. Figure out how to automate your computer’s config (I use ansibe) and it’s even lower. When that is setup you could reinstall and be ready to go in under an hour.
