I got stuck following https://www.hovatek.com/forum/thread-32664.html

I unlocked bootloader, and I made a custom vbmeta with all stock keys just to see flashing is okay.

I tried this command:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta-sign-custom.img

Then I got this:
Rewriting vbmeta struct at offset: 0
Sending 'vbmeta' (1024 KB) OKAY [ 0.045s]
Writing 'vbmeta'

And I got stuck. So I tried stock vbmeta to see if it works:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta-sign.img

It also got stuck. I tried without --disable-verity and it says FAILED:
fastboot --disable-verification flash vbmeta vbmeta-sign.img
Rewriting vbmeta struct at offset: 0
Sending 'vbmeta' (1024 KB) OKAY [ 0.045s]
Writing 'vbmeta' FAILED (remote: 'Write img fail!')
fastboot: error: Command failed

I also tried no option (no --disable-verification and --disable-verity) and I got FAILED.
I did try the same to stock and custom img, all got FAILED.

I am going to attach info-image for both stock and custom. Only flags variable is different
(0 for stock, 2 for custom).

The command I made for custom image is this:
avbtool make_vbmeta_image --key rsa4096_vbmeta.pem --algorithm SHA256_RSA4096 --flags 2 --chain_partition boot:1:keys/key_boot.bin --chain_partition dtbo:6:keys/key_dtbo.bin --chain_partition socko:13:keys/key_socko.bin --chain_partition odmko:14:keys/key_odmko.bin --chain_partition vbmeta_system:2:keys/key_vbmeta_system.bin --chain_partition vbmeta_system_ext:3:keys/key_vbmeta_system_ext.bin --chain_partition vbmeta_vendor:4:keys/key_vbmeta_vendor.bin --chain_partition vbmeta_product:5:keys/key_vbmeta_product.bin --chain_partition l_modem:7:keys/key_l_modem.bin --chain_partition l_ldsp:8:keys/key_l_ldsp.bin --chain_partition l_gdsp:9:keys/key_l_gdsp.bin --chain_partition pm_sys:10:keys/key_pm_sys.bin --chain_partition l_agdsp:11:keys/key_l_agdsp.bin --chain_partition l_cdsp:12:keys/key_l_cdsp.bin --padding_size 20480 --output vbmeta-sign-custom.img

Now I am out of idea. Can anyone help me?

FYI, my tool versions are:
avbtool 1.1.0
adb 31.0.3-7562133

ps. sorry for bad English and not using quote frame. I'm new here and I don't know how to use quote.

What I'm interested in right now is the stock vbmeta.
Are you saying you tried flashing the vbmeta contained in the firmware without flags i.e fastboot flash vbmeta vbmeta.img
and that failed also?
