I also have a pixel 6, still running the stock Google OS, but I'd like to try Graphene OS... Is there anything that worked on the stock Google OS that you had trouble with on Graphene OS?
I used to have a Huawei phone and there was a way to change the model number. It was an extra step I had to do first, but since the hardware was otherwise the same, I did manage to successfully flash another regions ROM on my US model.
Yeah, exactly. Let's say you're on instance B and I'm on instance C, and we both follow a community on instance A. You comment on a post, it will be stored on your instance B, and sent to instance A. Instance A will share it with my instance C because I follow the community, and it will be mirrored on all 3 instances. If instance A goes down, or doesn't exist anymore, the old post/comments will still be there on instance B and C. If you leave new comments after instance A goes down, they won't make it to my instance C. That's my understanding at least, hope that makes sense!
As long as there's a subscriber to the community on another instance, it will automatically have a copy there, that's just how the federation works. It's not really a backup, and it only has posts since someone subscribed to the community from that instance.
But if you're worried about what will happen to old posts from lemmy.world communities: if you can read it now from your instance, it will still be there if lemmy.world disappears.
If you subscribe to a community in a different instance, it's automatically mirrored there. If lemmy.world disappeared tomorrow, I'd still be able to view all the communities from lemmy.world on sh.itjust.works, for example.
If you post a new comment, it won't leave your instance, but all the old posts/comments will still be there.
