I just flashed my 78fk drive at my grandparents house with fwtoolbox and everything flashed correctly. There weren't any errors when flashing at all. The problem is when I turn it on the 360 logo comes up for a second and doesnt and logo doesnt complete. The 360 restarts itself and tries again. What did I do wrong. Is the sata cable not plugged in all the way or something? I'm gonna reopen it.
