Comment on Rooted Android phones vulnerable due to Android kernel patching flawsparent

Comments

Rooting in this context means unlocking the bootloader to allow for a custom OS/kernel that isn't signed by the OEM

That would not be the correct usage of the term "rooting". "Rooting" on Android systems generally means to install a `su` binary (like Magisk) that you can use to give apps root permissions, thus completely circumventing the normal android app permission system.

I'd rather have the ability to enroll my own keys so I can boot my own signed OS and maintain a root of trust that I own much like what can be done on desktop Linux with a TPM. IIRC Google's Pixel phones have this ability (and are one of the few phones that have this ability if I'm not mistaken).

I agree completely. I have a Google Pixel and use this with GrapheneOS.

This feature is `called avb_custom_key`, and yeah, unfortunately only some devices support it.
