I’ve been looking through the documentation and installation guides for PostmarketOS, and I’ve noticed there seems to be no mention of locking the bootloader after flashing.
Is that because there’s no issue with doing so, or because you can’t?
I’m looking at installing on a Fairphone 5, but anyone with any device that’s able to share their experience would be appreciated.
Only pixels let you relock the bootloader after flashing.
Frustratingly, grapheneos only supports pixels because of that.
That’s just plain wrong. Some others also allow it, for example: you could lock a Fairphone.
After installing a different os? So if I installed PostmarketOS, could I lock the bootloader? After looking in to it more, it seems like a pretty clear no.
postmarketOS does not seem to have implemented Android Verified Boot yet and I am not aware of Linux distros that do it.
Have a look at iodéOS, CalyxOS, GrapheneOS if you want that, at least for now.
I have Graphene, and I’ll be sticking with it for now.
I think my next step will have to be getting involved with implementing verified boot, because unless every phone suddenly starts shipping with TPMs and open bootloaders, I won’t ever be able to switch.
Finding a starting point is half the battle I guess!
There’s definitely enough to do, so if you want to contribute in that area, it’d be MUCH appreciated. :)
