Sounded interesting till I got to that. I would think anyone smart enough to make a chip that can do that would know it's the kernel that has the hole in it, not the dash, and HTF can we downgrade since the efuse is blown, the console shouldn't boot if you put a lower kernel on (and never removed the resistor). (unless of course they mean you can downgrade IF you removed the resistor before upgrading).
Don't get me wrong it would be awesome if this is true, but I'd like to hear more about the downgrading process. If it can truely work on a console that has been updated these guys have found a gold mine, I'd buy it.
Hahaha, downgrade the dashboard.
I suspect they mean downgrading the kernel using the same technique that robinsod did - corrupt the applied patches and it reverts to the previous kernel. From what i have read of robinsod's work about downgrading from 4552, it does not work using this technique, even if you did remove R6T3. It was speculated at the time that the file system was completely overwritten with one that will not work with lower kernels. Once he flashed his NAND with a dump of an older kernel it booted fine again. Thus, you need a dump prior to upgrading to 4552 to be able to downgrade to pre-4552 kernels since the NANDs are married to each individual 360 with a per-box key...
Robinsod performed the exact process with a LPC2148, which probably costs less that what this chip will cost. I suspect that they need to do some more research into the subject before they make such bold claims, or atleast provide more evidence other than them actually dumping the NAND (old news, sorry). This is nothing new and certainly does not look easier than what robinsod did. Plus, if they were smart, they would have used the alernate pinout on the bottom of the motherboard. It is much easier to solder to!
My two cents.
