Prepare a microSD (32GB or below capacity is preferred). Make sure it is in FAT32 format.
Get the update file ready.
Rename the file to update.yst and place it under the root of the microSD.
Eject it from the card reader afterwards.
Procedure for older ECU design with firmware file only. - (YouTube Tutorial)
Insert the microSD into the control unit. The red LED will be flashing rapidly. Wait until the LED becomes solid and eject the microSD.
New ECUs (v250+ for Electric Frunk; MARK 3.0+ for Model 3 Electric Tailgate) come with a new firmware system that contains two update files (firmware and config). - (YouTube Tutorial)
To flash the update.yst, you need to disconnect the power of ECU for 30 seconds, insert the SD card and reconnect the power.
The red LED will be flashing rapidly. Wait until the LED becomes solid and eject the microSD.
To flash the config.yx, keep the ECU connecting to power and insert the SD card.
The red LED will be flashing slowly.
Wait until the LED becomes solid and eject the microSD.
The LED should be flashing constantly now and you are all set!
