Apologies if this has been asked before, I’m sure it has, but after viewing the various threads on here I’m still a little puzzled, so hope you can answer a couple of questions more clearly. I’ve opened my XBOX 360, apart from removing the 6 torx screws (not as hard as I thought it would be), and I now want to flash the DVD-rom. Is it possible to render the XBOX 360 useless if I do the flash wrong? Can I role back to the original MS version? I’ve read the instructions for installing the new firmware and it appears pretty straight forward??? I’m just seeking some reassurance, that if it is carried out incorrectly I don’t end up with a brick.
