The bootloader passes this digest string to the kernel via the kernel command line ( androidboot.vbmeta.digest ).
Before Android 8.0, Verified Boot used dm-verity but lacked a unified structure for managing different partitions. Google introduced , which uses a data structure called VBMeta to store cryptographic digests (hashes) of multiple partitions (boot, system, vendor, dtbo, etc.). ro.boot.vbmeta.digest
The value of ro.boot.vbmeta.digest is a to the state of all protected partitions. Because vbmeta itself contains hashes of boot and system , a change in any verified partition would alter the vbmeta image, thus producing a different digest. The bootloader passes this digest string to the
You can view your current digest value using a terminal emulator or ADB with the following command: getprop ro.boot.vbmeta.digest Use code with caution. Copied to clipboard Empty Result The value of ro
