Use 7-Zip or WinRAR to extract the vbmeta.img from the AP file.
The vbmeta.img file contains cryptographic hashes for other partitions, such as boot , system , and vendor . During the boot process, the bootloader checks these hashes. If it detects a modification—like a Magisk-patched boot image —it will trigger a security violation, often resulting in a or an "Error verifying vbmeta image" message.

To understand the significance of vbmeta, one must first grasp the concept of Verified Boot. This is a security mechanism that ensures the integrity of the operating system from the moment the device is powered on. When a Samsung Galaxy M31 boots, it follows a strict chain of trust. The hardware verifies the bootloader, which verifies the kernel, and so on. The vbmeta partition acts as a central authority in this chain. It contains the cryptographic keys and hashes required to verify the integrity of other partitions, such as boot , system , and vendor . If the data in these partitions matches the metadata stored in vbmeta, the device boots normally. If there is a mismatch—indicating potential malware or corruption—the boot process is halted, or the user is warned. In essence, vbmeta is the checkpoint that guarantees the operating system is in a state the manufacturer intended.
