Hello, Good day! I'd just like to inquire if there's a way of upgrading the firmware (FW) of a Tesla Model S through USB flash drive or through another method. We’re trying to service a Tesla Model S to improve its performance and avoid problems on the 12v aux battery charge/discharge. The car was imported to the Philippines early in 2013, and still has a FW v4.x. There’s still no Tesla service center in my country. Since the car was imported to another country, we have no access to over-the-air (OTA) updates normally available to Tesla Vehicles. Additionally, we can’t use the local WiFi since the FW version that enables WiFi (v5.6) has not yet been installed. I’d be very grateful you could suggest alternative methods of downloading the latest FW to the Tesla Model S. Thank you very much in advance!
