Additional context

开发者你好，我在尝试安装boot时候提示了上述错误。
已经给了所有权限到ksu，线刷了多个版本的miui均有该错误，boot文件无论是卡刷包还是线刷包提取出来的都不行，BL锁已解。

When I use kernelsu on A12, the same error occurs.
When I switch to the Rom of A13, everything is normal.

I also encountered this problem, but I solved it like this

Tests found that this version does not support LKM kernelSU, but supports GKI version of KernelSU
Temporary startup is no problem, but once flashed, it cannot be started
After testing, it was found that it was an AVB verification problem. The following is the solution

Available GKI version: android12-5.10.198_2024-01-boot.img.gz

How to use: Unzip the file, and then flash the img in fastboot mode

1. Temporary startup img (restart invalid): fastboot boot kernel_file
2. After restarting, the phone has temporary root permissions, then install Hardware Assistant

If you click Install in KernelSU and install it directly, what is actually installed is LKM version
Click to patch the image, which is also the LKM version
Click to install to an unused slot, which is also the LKM version

1. Use kernelSU to grant root permissions to the Gear Assistant, then open the Gear Assistant
2. ROOT Zone -> Disable AVB2.0 boot verification/DM verification -> 3Disable AVB2.0 boot verification/DM verification
3. After that, restart the phone and flash the kernel normally
4. Flash the kernel: fastboot flash boot kernel_file

Now, my phone works normally and the version is GKI. If you don't need GKI, the above steps have actually solved this problem ; )
