How to correctly flash a benq drive in the xbox 360!!! MSDosFlash Method?

Hi,

I tried to flash the xbox 360 benq drive with the xtreme flash method using iprep on a usb.

However, the status wont change from the xf7 or whatever the correct way it was. I have the correct chipset, via I believe and that is not the case.

I heard that benq drives sometimes dont work this way and the best way is to use the msdosflash 32 method.

Can anyone explain how you do this??

I plugged in my drive and started the msdos app, and it asked me if I wanted to calculate the mdk or whatever it was not sure, and I said yes.

Then after that it took like 10 mins and my xbox 360 drive was making a noisy spinning noise. Does that mean it has been flashed? If not how would you correctly do it?/ Thanks
