Dualboot DVD firmware mod for the Xbox 360

chip select

Monday brought news of backups successfully booting on Xbox 360s with modified DVD firmware images. LittleJonny put together a tutorial on how to boot two different DVD drive firmwares. To perform this mod you need a second SST 39sf020a flashrom plus some resistors. The two flash chips are soldered directly on top of each other except for pin 15. Two wires are then attached. Which flash chip is used depends on which wire you pull to ground. Just add a switch and you can install a modified firmware on the second chip while keeping your original. I’m guessing Microsoft will put firmware detection into the dashboard to combat this, but this will keep your original firmware intact so you won’t have to reflash if something breaks.

shut up wootbike, anything you say == null due to your “first post” post.

How would microsoft check the firmware in the dash? Couldn’t you just plop another chip in the middle telling it to return whatever this new patch is expecting?

your != you’re != cool
well of course they can check for serial numbers or ‘auth codes’ like ‘microsoft’ and burn a link to diable everything if its not found. then you’ll just think that your mod screwed you’er xbox.

if you know what your doing you can work around it all. just like hack a day pps have proved again and again…..

Errr, people who post things that aren’t relevent to the topic makes me sad, and makes baby jesus sad, and errr lets say God kills a kitten everytime it happens.

So I think this definetly means that I want an xBox, and that it’s improbable to make an unhackable system… well atleast for microsoft.
