[Lenovo P11] Mambobuzzz:
Ah yes!!! That worked! Thank you!

Next problem. Fastbootd is here, device is recognized everything's fine but:

C:\Autre\Outils\ADB>fastboot --disable-verification flash vbmeta ROM/vbmeta.img
Rewriting vbmeta struct at offset: 0
Sending 'vbmeta_b' (4 KB) OKAY [ 0.001s]
Writing 'vbmeta_b' OKAY [ 0.007s]
Finished. Total time: 0.043s

C:\Autre\Outils\ADB>fastboot erase system
Erasing 'system' FAILED (remote: 'Partition doesn't exist')
fastboot: error: Command failed

C:\Autre\Outils\ADB>fastboot erase system
Erasing 'system' FAILED (remote: 'Partition doesn't exist')

C:\Autre\Outils\ADB>fastboot devices
HVA05BYV fastboot

I tried this: https://droidwin.com/how-to-fix-failed-remote-partition-table-doesnt-exist/ but can't seem to help.

EDIT: Here my vars:
