that leaves a total of 114mb of expansion room.

No. It's 128Mb (Mega bits) which is 16MB (Mega Bytes). The dash is 4MB, leaving 12MB.

My bad, I had not seen the board nor the #'s off the chip to look up the data sheets...(sorry for the stupidity).
god I want to take one of these things apart!!!
alright...(just looked at data sheets for the hynix nand chips)...
as for the extraction of data/flashing of the chip... I am crosschecking something for a quick&dirty dumper/flasher(will post info on it in a short while... stay tuned!)

The TSOP is encrypted with a per-box key, i focused on the TSOP in my research for a security vulnerability for about 10 minutes, then i realised that it was encrypted with a per-box key (absolutly no data off the TSOP made any sence even in a hex level for anything) My guess is that this key would be the same as the executable signatures (a.k.a: RSA-2048) but if anyone has a opteron based cray or 2 (the new model ones) that they are willing to lend to me for a few years i'd be willing to brute force decrypt the TSOP and see what i can find vulnerability wise.

i know this is off topic but i am just wondering if anyone knows where i can hire out a high speed 100+Ch LSA? thank you in advance

Can you try your firmware key from your dvd drive to decrypt it? (couldn't hurt) wink.gif

I don't think so..

All dvd keys are others. But, if you solder tsop from premium to other premium, console is normaly turned on. So, all consoles have that same key for decrypt flash I think..

Anyone understand me? laugh.gif

IMO

well it wouldnt work,

1) i think that the dvd key is actually an AES key,
2) if 1 is wrong, the dvd key is encrypted data, encrypted with the same key possibly as the TSOP, and decrypted with a public key which we have no access to

While browsing my 360HDD today I noticed a file on it called DASHBOARD. I know the dashboard isnt run off the HDD, otherwise core console would be in trouble.


So what is this file? a Backup of the dash or???

Oh? What was the path to this file?

BTW, some screens in games are also a Dashboard.

I would imagine it is where dashboard updates are downloaded/storage before installing to the 360's flash memory.

all of the above said, I believe that it starts its bios and runs self checks(unsure of what), then if everything is OK then it retrieves the dash from the NAND chip. Also, if the original dash was ~14 mb, and they "had" to cut it to 4, then there is something else on the chip or else they would not be worried about 10 more megabytes. even if the dash was 14mb, that leaves a total of 114mb of expansion room. why would MS want THAT much expansion room? They either have plans for some MAJOR software upgrade(but why would the cut the first dash down so drastically?), or their is something else stored on the chip.


The NAND is 16MBytes total (Mb=megabit, MB=Megabyte). There may or may not be anything but the dash on there. We'll find out when someone figures how to dump it.
