Okay, so I was trying to jtag my own xbox 360 with a falcon motherboard. Nothing went as planned, so I desoldered everything off the board. Now my xbox will only start up once with the 3 RRoD. And it won't power up by the RF board, it just starts up when I plug the power connecter in. Is there any ways I can test to see if all of my solder connections are good or bad? I am new to the modding scene, so please be as specific as possible. Thanks in advance! I also can't power it down with the RF board.
