Umm i think they are in the cpu.

arielzadi · « **Reply #16 on:** December 19, 2009, 07:46:00 AM »

so basicly downgrading is impossible unless there is a way to change the cb within the cpu
am i correct?

K,
this thread is chock full of idiot

There is no way to downgrade on the 360 Period.
The only hope for people who have updated is for a new exploit.
There has only ever been once exploit discovered.
Good luck finding another (Impossible? no. Unlikely? yes)

Efuses :
Efuses are inside of the CPU. There is no way to 'swap' them. Period
R6T3 is a RESISTOR
Removing R6T3 prevents fuses from being blown
There is no known way to rewrite or reset efuses. It is very likely this is imposible
MS has never done it with an update, nor is there any provision in the security system to require it
If this were possible it would break their security system so if this function existed it was likely disabled

CB is stored on your nand

please read this-it says that they can be changed
http://en.wikipedia.org/wiki/EFUSE
i am just saying that it is written

you could physically replace an efuse, but you'd have to spend millions

get a freaking new 360 that is exploitable.. you're stupid for having killed homebrew on your console

i can't agree with you more Loto_Bak xD

zomg haz we replace 2 teh efuse with my solder gun!?!

if some one could look deep deeep deeeeeeeeeeeeep . i mean deep into the nand. Im sure ther is a hole for us to get it to work... . Or then from nand to get some thing to work and then to xel.. You never know. Evrything is hackable... The sony is forsho hackable but it could take years to find any holes.

Hello,
i need a premodded xbox 360 with the jtag hack.
If you know any place where i could buy it will be cool.
If anyone is good enought to do it we can find a deal for a fair price.
Thanks in advance

Those interested in eFuse's should read this:

i sorta understand what arielzadi is trying to say with that wikipedia page. the last line says: "This process does not physically destroy the eFUSE, so it is reversible and repeatable, using JTAG Programming."

technically, yes, but that page also says in many systems that use eFuses, meaning not all are reversible. you dont think m$ would include the jtag points on their motherboard to reset the eFuses.

Please, if you would be so kind to redirect me to the proper section i'll be happy to post in the proper way.
Thanks
