Hi guys here's the deal, this Saturday i was trying to flash my cousin's xbox BenQ drive that still has the original firmware, I followed the instructions in the IPREP V009 tutorial, but when I was at the MTK vendor intro his drive didn't get the good status of 0x73

. It keeps from 0x51 and 0xD1 only. I'm using the xbox power supply to turn on and off his drive, but not a VIA or NFORce sata drive.
PS. I did this method with my xbox and worked flawlessly.
PS2: Is it totally safe to unplug the power cable from the drive with the console On?! I mean, because I have to do the Geremia's Unlock method and I'm using my xbox power supply, so i got a little scared doing that.
