Now ro.boot.vbmeta.digest will match the hash of custom_vbmeta.img. Note: Google Play will still detect a custom key, but device integrity is cryptographically sound. ro.boot.vbmeta.digest

The bootloader calculates this digest at runtime as it verifies each partition. It then passes this value to the Android kernel using the command-line parameter androidboot.vbmeta.digest. Once Android starts, it takes this value and exposes it as the read-only system property: ro.boot.vbmeta.digest. Why It Matters: Play Integrity and SafetyNet Informative Paper: Understanding ro

Advanced users who root their devices for legitimate development or customization often find themselves locked out of banking apps and streaming services. When a user unlocks the bootloader or flashes a custom recovery (like TWRP), they often have to flash a "patched" VBMeta image to disable verified boot. This instantly changes the digest, flagging the device as "unclean." platform/external/avb - Git at Google - Android GoogleSource
