Please help to install graphene OS on my pixel6a, to install the OS through the device, it just rebooted in the bootloader and that's it. The bootloader unlock was able to reinstall the OS, but now I can't lock it again.
When entering a command
fastboot firmware lock
I get an answer
FAILED (remote: "invalid android images, skip lock")
fastboot: error: command failed
On the site https: //flash.android....uejay-user&signed=true also plans to install the OS and block the bootloader, but gives an error. During installation, the device reboots into the bootloader and the site gives an error that the device is busy.
At the moment, when you turn on the phone, only a white screen with the inscription google.
I have Manjaro Linux on my PC, but it's unlikely that grapheneOS developers for Arch will also get a guide for this problem.
Also the team
OEM fastboot lock
issues
FAILED (remote: "Invalid oem command lock")
fastboot: error: command failed
