I also provide the result of the "fastboot get-var all" command and there is no partition size. Usually there should be something there but not this time.
The recovery is gone and the only thing that actually work is the "Show barcode" option in fastboot.
When my friend chose the Reboot or Recovery mode, the Google logo appear for a >0.6 second then turn it self off.
Also tried booting into EDL mode but didn't seems to work. It might required a EDL cable.
Any help would be appreciated since my friend is pretty much desperate at this point since quaratine prevent him from getting a step out of his house lol.
He also send me his Pixel through mail lol.
