Execute the following command in your terminal/command prompt:
fastboot flash vbmeta_b --disable-verity --disable-verification vbmeta.img
: Without this patch, if you flash a modified boot image for rooting, the existing vbmeta will detect the signature mismatch and trigger a bootloop or direct the device back to the bootloader. patch vbmeta in boot image magisk
When you root with Magisk, you normally patch the . But on devices with Verified Boot (especially Pixel/Android One/Modern Samsung), the system also checks the vbmeta partition. If vbmeta doesn’t match, the device won’t boot.
Google introduced with chained partitions. Patching vbmeta for boot alone is insufficient—you must also disable verification for the vendor_boot partition: If vbmeta doesn’t match, the device won’t boot
For devices that lack a separate vbmeta partition, Magisk can patch the necessary vbmeta flags directly into the boot image. This is the most integrated approach and requires no separate vbmeta flashing.
Also, I want to mention that while the patching of vbmeta does allow more possibilities for device customization, users should still be cautious and understand the risks involved with modifying their device's boot image. Improperly patched vbmeta or incorrectly modified boot images can still cause problems with device security and stability. This is the most integrated approach and requires
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
To bypass AVB, Magisk targets the struct. The critical operation is modifying the flags field.
