Hi - I seem to be first, but I'm stucked at the installation.
The bootloader seem to be unlocked, but neither the script nor manual commands are working.
First of all - this is my setup
I'm working on an actual debian system with
adb
Android Debug Bridge version 1.0.41
Version 36.0.0-13206524
Installed as /usr/lib/android-sdk/platform-tools/adb
Running on Linux 6.17.11+deb14-amd64 (x86_64)
fastboot
fastboot version 36.0.0-13206524
Installed as /usr/lib/android-sdk/platform-tools/fastboot
**./flash-all.sh** 
_Available devices:
XXXXXXXXXXXXXX         fastbootd usb:1-10
Warning: bootloader does not support slots, and slot a was requested.
Warning: skip copying bootloader image avb footer (bootloader partition size: 0, bootloader image size: 12777556).
Sending 'bootloader' (12478 KB)                    OKAY [  0.501s]
Writing 'bootloader'                               FAILED (remote: 'No such file or directory')
fastboot: error: Command failed_

Also weird:
fastboot flashing unlock
FAILED (remote: 'Unrecognized command flashing unlock')
fastboot: error: Command failed

The getvar-command is working:
