Ro.boot.vbmeta.digest New! -

Crucially, this digest is . It cannot be changed by the Android OS once the kernel boots. It is set by the bootloader.

This property is a primary indicator for security services like (formerly SafetyNet). ro.boot.vbmeta.digest

If you modify partitions (e.g., flashing a custom recovery or rooting with Magisk), the VBMeta digest will change. Crucially, this digest is

Modern Android devices rely on a chain of trust. At the heart of AVB 2.0 is the vbmeta partition, which contains hashes and signatures for other partitions (boot, system, vendor). During boot, the bootloader computes the digest of the vbmeta image and passes it to the kernel via the device tree. The Android system then exposes this value as the read-only property ro.boot.vbmeta.digest . This property is a primary indicator for security

Inside vbmeta , there is a rollback_index field. If the bootloader enforces rollback protection, it compares the rollback_index inside vbmeta against a stored value in tamper-resistant storage.
