If you install a custom ROM, custom kernel, or root your device, you are modifying the boot or system partition. This requires flashing a new vbmeta image, which produces a different digest. ro.boot.vbmeta.digest

: This digest acts as a "fingerprint" for your system's current software state. During boot, the system calculates a new digest and compares it to this stored value; if they don't match, the device may refuse to boot or display a warning. Security Checks It acts as a unique fingerprint generated during

: The bootloader calculates this digest after verifying the vbmeta signature against the hardware-backed public key. 3. Role in the Chain of Trust This requires flashing a new vbmeta image, which
