We are trying to flash A MS 25 with the newsest firmware. We have A PNY flash drive with the firmware installer on it. But it won't boot while in the computer. We have disabled all of the other drives on the computer. But it simply will not boot. Please help. Update:I finally did it! I had to use another computer, and I change to boot order of the USB drive. The other computer kept booting into the "u3" partition of the flash drive. And kept causing the computer to freeze. But now I have another problem. I thought my DVD burner was Dual layered but it's not. And I'm going to have to purchase one. But I don't know which one to get. I've read alot guides, even some here on afterdawn. But I'm still A little confused. Some guides say to use A samsung drive to rip xbox games, while others say to use A pioneer? do I need both? and what kind of software do I need? is "kreon" the best choice? or is there something better? and do I need to take apart the samsung drive every time I want to backup A 360 game?
