The Free60 Project wrote:On Tuesday, Microsoft has released an Xbox 360 software update that overwrites the first stage bootloader of the system. Although there have been numerous software updates for Microsoft's gaming console in the past, this is the first one to overwrite the vital boot block. Any failure while updating this will break the Xbox 360 beyond repair. Statistics from other systems have shown that about one in a thousand bootloader updates goes wrong, and unless Microsoft has a novel solution to this problem, this puts tens of thousands of Xboxes at risk.
M$'s new update bricked my XBOX (about 3 months old) and there are hundreds of posts of the same at the XBOX site's forums.
Also, people with units out of warranty are getting screwed too since M$ is telling people that they won't fix them (well, they will, but for $100).
