to inspect whether a device is running a modified or official firmware version. Related Properties You will often see this property alongside others such as: ro.boot.vbmeta.hash_alg : The algorithm used (typically SHA-256). ro.boot.vbmeta.size : The size of the VBMeta image. ro.boot.verifiedbootstate ro.boot.vbmeta.digest

This "Digest" value must match ro.boot.vbmeta.digest on a locked device. Legacy devices (Android 7 and below) don't have AVB

Not necessarily. Legacy devices (Android 7 and below) don't have AVB. Also, some OEMs (e.g., Samsung with Knox) implement their own verification ( ro.boot.warranty_bit ) and may not propagate the standard AVB digest. However, a missing digest on a modern (Android 10+) device usually indicates a corrupt or disabled verification chain.

Because the structure of the metadata blocks has fundamentally changed, the hash calculated by the bootloader changes along with it. On many chipsets, completely disabling or clearing out verification results in ro.boot.vbmeta.digest returning a blank entry, a sequence of zeros, or a completely abnormal hash value.
