You have to write to support team or regional dealer

Desde donde dice communities ve a faks ahi dice que hay que ciontactar a autel, antes
no era necesario

I want to change language un french

I believe the Fix to this would be to write to Autel or the dealer and pay a $US 250 transfer fee or some sort for that device's serial number. I then believe a software update becomes available in a day or two that allows the changing of the language for that device.

This is just MY opinion of what happens based on what I recall seeing on various forums. There is an Autel consultant "Curtis Hardin", who Will get it done for you when you book a consultation session with him. He will act like the middle-man between you and Autel's engineers to get your device rectified.
