Yes, the bootloader is unlockt. Everything is ready to be signed and flash, using fastboot and SP_flash_tool running on Linux mint.
Soon as I figure out how to implement your code in to my project. I can't figure out how my vbmeta.img info shood lock like?
Is it this:
python avbtool make_vbmeta_image --key hovatek.pem --algorithm SHA256_RSA2048 --flag 2 --chain_partition recovery:1:keys/hovatek.bin --chain_partition system:2:keys/vbmeta_system_key.bin --output vbmeta-custom.img
