183w ago - Today sabrax from XBoxHacker.org (linked above) has shared a video demonstrating a way to trigger 'Manufacturing Mode' using a Memory Card on unmodified Microsoft XBox 360 consoles, followed by receiving an 0x81DA07FF error.
Shortly after, rupal has posted both the extracted XEX & INI file along with a raw dump for examination by other devs.
To quote: "It is happening only when a (specific) memory card is inserted, on 2 different Xbox 360's, it is entering "Set Manufacturing Mode", and after some time is showing this error: 0x81DA07FF.
Here is video - for a split second there is a blink on 0:20 - 0:21.
This exact memory unit should be 100% genuine (other MU from the same batch is still working with the latest dashboard).
Tested offline, tried it also on a unbanned and banned console latest dashboard, same result, "MTE Screening Utility" and so on as in seen on the video."

would be real nice if eventually this would lead to being able to downgrade the 360s back to an exploitable kernel.. or just be able to reset the efuse's if thats even possible.. would bring the price of used non-updated 360's way down..
so it should be possible to 'reset' it... i wonder if anyone has been working on this for either the 360 or the ps3??!
