The led cannot be solid blue in the first step

I bought a EVO-ALL and T-harness for my 2009 silverado 1500. I connectted the T-harness to my truck. I press and hold the button on then EVO-ALL, then plug the 4-PIN data wire to EVO_all. But the led on EVO-All cannot to be solid blue. So I have no chance to release the button. I waitted long time and tried sereral times. Same problem. So I cannot pass the first step when I tried to install it. One more question, the EVO_All I got shows EVO_RS on the box, not EVO-GM. But the T-harness is Thar-GMt4. Is it the problem. Thanks,
