Press and hold power and home for 30 seconds or until it turns on

The GP instructions are backward. You should connect, then power off. If you power off and then connect, the idevice will power on.

Well what's happened to get you in this state?, you're not the OP and you and give no explanation at all, perhaps that might help.

Well I have restored Iphone to factory settings and restored back up through itunes, that was the only way I could get it to power on. I plan to try again.
