Did you perform a master reset after the upgrade? If not, do that and see it everything is working again.

Hi,
I tried reset by holding Vol+forward,
also start engine+engine off+open door+lock door+close door.
Didn’t help.
Maybe I can flash it again? or downgrade?

A master reset is different than what you did above…
