Vbmeta Disable-verification Command

The primary users of this command are developers, security researchers, and enthusiasts engaging in Android customization.

| Risk | Description | |------|-------------| | Security loss | System partitions can be modified without detection. Malware could persist in system/vendor. | | Boot failures | Some devices (Pixel 6+, Xiaomi, OnePlus) may still refuse to boot if vbmeta flags don’t match hardware keystore state. | | No OTA updates | Over-the-air updates may fail because they require verified partitions. | | Data loss | Wiping userdata is sometimes required after changing verification state. |

Recommendation: Always take a full backup and have stock firmware available before running this command.

Use the appropriate command for your device:

For Google Pixel / AOSP-based devices:

fastboot flash vbmeta --disable-verification vbmeta.img

For most modern devices (disable both verity and verification):

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

If you don’t have a vbmeta.img (rare – do not skip): Some guides incorrectly claim you can use --disable-verification without an image file. This is wrong. You must have a vbmeta.img file (stock or empty). Use the stock one from your firmware.

Better approach – create an empty vbmeta with flags:

fastboot flash vbmeta --disable-verity --disable-verification --unspecified vbmeta.img

But note: --unspecified requires a dummy image. The safest is to download your stock vbmeta.img. vbmeta disable-verification command

After Magisk patches your boot.img, the partition no longer matches the hash in VBMeta. Without disabling verification, the device will enter a boot loop or display a corrupt screen. Running the command allows the modified boot image to load.

Navigate to the folder containing vbmeta.img and run:

fastboot flash vbmeta --disable-verity --disable-verification vbmeta.img

For A/B slot devices (Pixel 6+, many 2021+ phones), flash to both slots:

fastboot flash vbmeta_a --disable-verity --disable-verification vbmeta.img
fastboot flash vbmeta_b --disable-verity --disable-verification vbmeta.img

The command vbmeta disable-verification is typically used with fastboot to modify the vbmeta partition so that the device skips hash verification of other partitions (like boot, system, vendor, product). The primary users of this command are developers,

Note: This is different from disable-verity.

Disabling verification allows you to flash unsigned or modified partitions (e.g., custom kernels, patched boot images) without the device refusing to boot.

While rare, it’s good practice:

fastboot flash vbmeta your_backup_vbmeta.img

(You can dump it if you have root, but if you’re here, you probably don’t yet.) Recommendation: Always take a full backup and have
