It looks like a new XBOX 360 Corona MoBo revision was spotted by the guys over at hackfaq.net highlighting some security changes.

Thanks to the guys over at hackfaq.net, there's some info of a new ‘downgraded’ Corona revision (v4? or v3/16mb) for the XBOX 360.

As expected, there are some security changes. Here are the main two, via Homebrew-Connection:

- There is no longer POSTbit connected to a point outside of the processor. The POST is used to get the debug info from the console and is used in the RGH to know if the console start glitched (ie start correctly) or if it need a reset to try another time.

This means it’s now a lot harder to glitch the new machines … for example the russian guys over at hackfaq removed the CPU to get postbit access. Let’s hope hackers find a alternative to the POST.

- Some resistors linked to J2C3.X pads have also been removed. These points are used to dump/flash the nand and for i2c SDA/SCL signal transmissions. You will need to brigde the pads to be able do read/write and properly send the i2c signals.

According to them, most likely this isn't the same Corona revision that T-X was able to glitch, as they've said that one has a 64MB NAND, while the MoBo described here is said to have a 16MB NAND. But of course, for the moment, that is just speculation.

So, just stay tuned for more news about this new Corona rev. in the upcoming days!
