I rechecked the if cable is faulty, but it link fine tested with Ohm-meter after soldering....

You said you connected the Ground to pin 4 of the programmer. Well, pin 4 is not Ground. Pin 3 is.. please look at the connector's diagram "ReSt" posted above.. João @jhsa,@Rest... I will try changing pin4 to pin10 I was able to get 5v with Vcc against pin4, if it's not ground, then I sho...
