I cannot flash my phone because "Device is no longer supported"

I cannot flash my phone because "Device is no longer supported"


I've tried to install TWRP, but since I ran the command "fastboot flash boot twrp-dogo-3.2.3-0-dogo.img", my phone doesn't boot anymore, the screen remains black.

I want to repair it with Xperia Flash Tool but I see the message "Device is no longer supported".

It also shows the message "Please refer to update session a4ccac8b-1d2f-4737-90f5-a84cbfdf2eac if you need to contact Emma support."

What can I do to restore a valid boot image? My phone can still enter to fastboot mode and I can still flash the boot partition. The Xperia Companion also fails to repair it, it requires me to unlock my screen but it is black.

Best regards.
