Tips to Unlock Porsche MG1CS002 H80 ECU with Flex

Problem:

Failed to boot glitch unlock an Porsche Bosch MG1CS002 H80 ECU using Magic Motorsport Flex programmer. Tried all the connections and resistors (3.3 ohm/5 ohm/ 6 ohm), with short/long cables, with adapter E1 without adapter, all no luck. Any solution?
