(Length depends on the hash algorithm – typically 64 hex chars for SHA256.)
adb shell getprop ro.boot.vbmeta.digest
This property represents a of all VBMeta structures used during the boot process. It is a critical component of Android Verified Boot (AVB) , ensuring that the code being executed comes from a trusted source and has not been tampered with. Key Technical Details ro.boot.vbmeta.digest

The "heart" of this system is the VBMeta structure, which contains hashes (fingerprints) for individual partitions like boot , system , and vendor . When a device fails to boot after an
When a device fails to boot after an update, developers often look at the VBMeta status. If the digest calculated by the bootloader doesn't match the one expected by the system, the device will trigger a "Rescue Party" or stay stuck in fastmode, citing a "VBMeta image verification failed" error. How to Check Your Digest
Formally: Given vbmeta_digest = SHA256(vbmeta_image) , and vbmeta_image includes hash(boot) , hash(system) , etc., then ro.boot.vbmeta.digest is a compact, non-repudiable identifier of the exact software version and integrity state of the device.
