Hey @my123 > However, there's a catch still: there isn't a central update service. So while you might use a custom OS that way, you'll still need to update the vendor partitions (with the drivers, both kernel and user-mode ones) out of band in that scenario to get updates for those. > This mechanism allows to have universal Android images that work across all of the ecosystem, and can be used for GNU/Linux distributions on phones too if there's motivation to do so. So assuming my bootloader is unlocked, have a GSI compliant phone, what is the remaining work I would need to have done in order to get it working under linux (and by working I mean all devices - including cameras and etc)?

This can be fixed with an engineering effort to do so to make it work on devices launched with Android 12. The Linux on phones community is very small and that causes problems in this case.

This would fill the last chunk of custom per-device bits. I wonder how big the audience would be for such a project though. :)
