> Yes, in a custom ROM GrapheneOS is an alternative OS, that keeps the same security model as Android. It's not a "custom, hacked thing that disables the security". > Assuming a phone was securely installed (after verifying sha/sig) with lineageOS RECOVERY and ROM - it will not accept a build with different sign keys. (i.e) AOSP keys. Do you know which keys are used by Lineage? My understanding is that some phones running Lineage use the testing keys. Simply because some phones don't allow "custom keys". But that means that it defeats the point of the signing. Are you saying that the signing is useless in Android?
