You are pushing the drive half-way back in, correct?
Also, this tutorial assumes that when you connect the SATA CABLE and the POWER CABLE to your drive that the POWER CABLE/CK3 is already supplying POWER to the drive (or your 360 is turned on, either way (IMG:

What is the exact error you see at the 'black screen' (the DOS area, where the firmware validation is failing for you)?
i'll get it word for word when im home, so just to know after the esq parts my xbox should be on and both power and sata should be plugged in and my drive should be halfway?
