Hello, so i flashed a software with bad checksum abd now my mercedes wont start. So i was told to bench flash it in bootmode. I was wondering is this the real pinout(https://www.lesamisdelaprog.com/pinout- ... -mode.html
)? Do i apply the gnd and +12v to the wires between ecu and obd plug or like in the first picture of the link straight power to pin 9 and 13?
