Why, instead of safely entering a BIOS setup, does the cell phone brick when installing the Custom ROM wrongly? Wouldn’t this protection be better for users? I mean, this could be done through ADB.
Also, do you think it’s possible that this way of doing things will come to the computer, with ARM hoping to gain a good share of the market and all?
You can replace the OS on most Android devices.
Specifically- devices made by Google have been unlocked allowing replacement of the software.
You still have to put together a working kernel and drivers, environment, etc.
Not much stopping folks from doing that though.
GrapheneOS, Ubuntu, and others have made headway for some devices.
Each device potentially uses different hardware implementation and features.
Graphene is targeting only google pixel devices.
Ubuntu touch and Ubuntu phone have been picked up by I think postmarketOS
I think AOSP is the best bet for the largest majority of Android users.
Kernel dev is a fun hobby.
