Waiting for moderator approval since I am a new member, but if approved download from Google Drive and put it on a USB-C Flash drive or USB with a USB-C Flash Drive. Plug it into your device, you might need to keep it plugged in exit the vehicle, lock it, and re-enter the vehicle. This will allow 9" screen to turn off, once turned on it will find the update. You can have it update the MCU if it asks, but it will not correct the remaining battery and mileage. Once you connect to WiFi and run update search it will ask you to choose interface and update MCU when it restarts all will be working again.
