On devices with a dedicated vbmeta partition (most modern Android devices from 2018 onward), you either patch the vbmeta partition or instruct the bootloader to skip verification.

The vbmeta partition contains:

: Magisk modifies the boot.img . Without a corresponding update to vbmeta , the device detects a signature mismatch and triggers a bootloop or a "Your device is corrupt" warning.

For a complete implementation example, you can use a batch script that handles slot detection and flashing.
