Im not a pro but to tell you the truth your looking at the risk when you mess up on disk burning.
you flash the drive right then you should be fine till they update the xbox with software that wont work with the new BIOS on the drive I have not done it but I have looked in to it if you RIP a disk and its got something micro$oft see's like sectors are mixed up some way the xbox will send a report of it so I was told.
but anyway you modify the xbox theres a chance you can get banned no matter how low, it remains there.
