So people, all people in this thread know that all echo's run android( oook fireos) and creating a cfw would be trivial because of what I've discovered:

If you search amazon source code on google, you can see a page that provides kernel, vendor etc for amaozn echo's.

WHAT IT also provides is verity keys!!!!!

so even though bootloader cant be unlocked, why cant we build a rom that uses verified boot from these keys to create cfw?

Share your thoughts.

EDIT: SOme of you are probably wondering, wth is a verity key? well, it is what is used to make a vbmeta image. The system partition is then checked for tampering using the hash from this image, and only then it will boot. So it will make a custom rom seem like an official firmware update to the echo.

Has anyone attempted to actually build a rom with this method?
