yeah i got lucky with an rrod fix as well. this xbox i just fixed has the last exploitable kernel so im happy. =]

So why cant you downgrade it with an infectus chip with that time hack?
... Efuses, and your bootloader is gone nothing to get it back.

Half correct Fuses are blown but the Bootloader isnt gone the CB been updated to blacklist KK kernal.
and buy a RROD 360 on ebay fix it then jtag it.

3/4 correct...the Efuses (more then one) have been blown and the CB has been locked down(Efuse blown) from this Meaning the new bootloader is in affect...

. But i think soon we will find a other way to downgrade... Nothing is impossible in hacking 
Post by: arielzadi on December 19, 2009, 06:58:00 AM
so i could have a better understanding of how hte hole process works-are the efuses embeded in the cpu?
how large are they
is there anyone in this world thats has the skills to swap them ?
EDIT:
just found this on wiwkipedia
"The primary application of this technology is to provide in-chip performance tuning. If certain sub-systems fail, or are taking too long to respond, or are consuming too much power, the chip can instantly change its behavior by 'blowing' an eFUSE. This process does not physically destroy the eFUSE, so it is reversible and repeatable, using JTAG Programming."

Dremel sells them . And they are pritty smal look on google xbox 360 R6T3 . There you see how smal it is. Its pritty smal but whit that ironsolder you can solder it back. But as i said before i think it gose into e80. But you'r cb is allredy updatet so i don't think you could be able to get it to work.

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

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

If anyone is good enought to do it we can find a deal for a fair price.

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.

jumojn, you are by far one of the dumbest, uneducated people i have seen on these forums who "knows what they are talking about"
hex editing as great and all, and it will uncripple a banned 360 but you fail to understand that everything important on the nand is SIGNED, as in encrypted, by a big long key, known as the CPU key, which for some reason is stored in the CPU's bank of efuses, which can only be read out with Xell. and cannot, by any m,eans other than decapping the CPU be accessed physically. if you want to, be my guest and go decap that mofo with your cheap ass radioshack soldering iron and get back to us on how that works out
and please refrain from knowitallism until you can actually form a statement about what you are talking about that doesnt sound like you pulled it directly out of your a$$

I've been waiting since the update for a new hack, and I only see in these forums people doing nothing but slowing the scene.
We should work together, we should try random things on our consoles just to make it unstable, to comment how to get that unstability, and to try to gain control of the console. If we all do this, maybe we can get somewhere.
Please, stop saying "no, stfu noob" to people that only wants to have a hack in their powerful but limited console, and start saying useful things, like the previous #19 by loto bak.
I'm gonna try everything just only to hang or make unstable the console. I suggest you all to help, just to get what we want in less time.
I really don't know anything about hacking, but if someone knows possible ways to find an exploit...please comment
PD: Is everything signed in the HDD? I mean, even the game logos? Maybe some modded picture, or modded text can exploit the console...

1. Read a bunch of forum posts. Now you are a computer engineer.
2. Speculate
3. ????
4. Profit!!!!
Oh wait, nevermind, I'm full of shit. Downcast, I do honestly respect your thirst for knowledge, and it is commendable that you are dedicated to learning new things.
Sorry to burst your bubble, folks, but the people that develop the hardware in the XBOX 360 are extremely knowledgeable and technical people. They have Computer Engineering and Computer Science degrees; likely, most of them have completed graduate school. These people work on the cutting edge of technology. They aren't bested by a bunch of dolts that lurk on message boards, talking in purely speculative terms.
The people behind the SMC hack are most likely equally qualified individuals. I'd be very surprised if any of them were completely self-taught. If I had to bet, they're a combination of EE, CE, or CS students, graduates, or working in the field. They have sophisticated knowledge about the internal components used in the 360. They have advanced technology at their disposal and know how to use it. They studied the architecture of the 360 and learned as much as they could, reverse engineering new components as they found them. They did lots of experimentation and I'm sure they failed... A LOT.
I'm not trying to discredit the community, but there are those on these boards that have a clue about how the hack works and then there are those that have just enough technical knowledge to think they do. It can be extremely hard for the uninitiated or the uneducated (not in the broad scope, but in the CS/CE field) to tell these people apart.
What it boils down to is that if you're just poing through some NAND dumps in a hex editor, you're are highly unlikely to make any useful contribution to the development of a new exploit or hack. The only thing speculative topics accomplish is pumping more mis-information into the minds of the masses who will believe anything they read. Of course this information will clunk through the rusty gears of these people's minds and exit through their fingertips in a later post down the line. Then this cycle repeats until this speculation is mutated into 'fact.'
The moral of the story is to know what you don't know. Either put down the mice and start studying to get into an engineering school or leave the heavy lifting to those who are capable.

It's annoying reading so many posts about downgrading the current kernel, but we should never say something is impossible. It could happen one day or maybe a different exploit to hack kernel 8955.....be patient!
The thing is that it is impossible to downgrade due to the way Microsoft secured the console.
The only way updated consoles might have any hope is if they discover a new hole that can be exploited. But remember the current exploit is the only one discovered to date and it took 3 years to be able to able to really make mass use of it.
