In 2021, many devices (like the Pixel 6 and early Pixel 7 series) implemented stricter AVB requirements. Without disabling these flags, attempts to flash a custom boot.img or kernel would result in a or a "Your device is corrupt" warning. This command became the standard "gateway" for users moving from stock firmware to customized systems. Steps to Use the Command
: Connect your phone to your PC and run: adb reboot bootloader .
Android Verified Boot (AVB) ensures that all executed code comes from a trusted source. It prevents malware from tampering with system partitions during the boot process. The Role of vbmeta
: Flashes the stock or empty vbmeta image while applying the disabling flags to the device's hardware flags. Prerequisites for Using the Command
To use the vbmeta disableverification command, you'll need:
: Disables dm-verity , which checks the integrity of the filesystem blocks.
The primary barrier to flashing custom software is Android Verified Boot (AVB). To bypass this security check, developers and enthusiasts use a specific Fastboot command: fastboot --disable-verification flash vbmeta vbmeta.img . What is vbmeta and Android Verified Boot?
AVB establishes a that starts with a hardware-backed key and extends through the bootloader to the VBMeta data. During every boot, the bootloader checks the signatures against the stored hashes in VBMeta . If the bootloader detects that a partition’s content has changed (like a patched boot.img from Magisk), AVB will see this as a security violation and will either show a warning or refuse to boot entirely.
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img How to Disable DM Verity and Verification on Android
Place your stock vbmeta.img file directly into the Platform-Tools folder. Type the following command exactly as written and press Enter:
Note: On some devices with virtual A/B partition slots, you may need to target specific slots using fastboot --disable-verification flash vbmeta_a vbmeta.img and fastboot --disable-verification flash vbmeta_b vbmeta.img . Step 4: Reboot Your Device
In 2021, the vbmeta --disable-verification command was a vital tool for Android power users. It effectively bypassed the stringent checks of Android Verified Boot, allowing for customization, but it fundamentally compromised the integrity checks put in place by Google. It is crucial to understand that this should only be done if you are comfortable managing your own system integrity.

In the earlier days of Android (pre-2019), simply unlocking the bootloader was often enough to flash a custom recovery or root. However, by 2021, the landscape had changed drastically.

For power users, developers, and root enthusiasts, the phrase became a mantra. If you were flashing a custom recovery like TWRP or rooting your Pixel or Xiaomi device in 2021, you likely encountered this command. But what exactly does it do, why did it become essential in 2021, and how do you use it safely?
