Follow these steps carefully to flash the vbmeta image with verification disabled. Step 1: Prepare the Files
In simpler terms: The device will no longer care if you modify system , vendor , or boot after unlocking the bootloader.
fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta_a.bin
The vbmeta.img file extracted from your current, official stock ROM (it must match your current build number). Step-by-Step Instructions
Open a Command Prompt, PowerShell, or Terminal window inside that specific folder. Step 2: Boot Your Device into Fastboot Mode vbmeta disable-verification command
file contains the cryptographic digests for various partitions (system, vendor, boot). Verity vs. Verification: Disable-Verity: , which checks partition integrity at runtime. Disable-Verification:
To understand the command, you must first understand . Android Verified Boot (AVB)
: This is a specific flag passed to the fastboot tool. It modifies the header of the VBMeta image during the transfer, changing the internal flag to tell the bootloader, "Do not verify the integrity of the partitions listed here."
Boot into fastboot:
Once the flashing and wiping processes finish successfully, restart your phone: fastboot reboot Use code with caution. Troubleshooting Common Errors 1. "Unknown option --disable-verification"
The partition contains metadata like cryptographic hashes and signing keys used to verify other partitions, such as system , boot , and vendor , during the startup process. If you try to flash a custom file (like a Magisk-patched boot image or a custom recovery) without disabling these checks, the device will detect the modification and refuse to boot, often resulting in a bootloop . The Command Breakdown
To successfully execute this command and its variations, you generally follow these steps: Unlock the Bootloader : This is an absolute prerequisite. You cannot modify the partition on a locked device. Obtain Stock VBMeta : You must extract the vbmeta.img
You usually need the vbmeta.img file extracted from the official Fastboot ROM/Firmware of your specific device model and version. Follow these steps carefully to flash the vbmeta
Some developers provide a "padded" or "empty" vbmeta.img . This is a tiny file that contains no data but satisfies the bootloader's requirement for a partition to exist while having all verification flags turned off by default.
This occurs if you are using an outdated version of Fastboot. Early versions of the tool did not support AVB 2.0 arguments.
Open a command prompt or terminal in your platform-tools folder. Run the Command: Type the command above.
