So unlike the font exploit, this method has the advantage that the dash boots normally, and you can play original Live games without being banned?

Does this method patch the kernel? If so, when and how? And next time you turn the xbox on it will be back to normal, kernel wise (dumb question)?

Look forward to some quick comments.

as long as u play ur original games ur kernel doesn't get patched, but when ur loading ur evox, then ur kernel is getting patched, so u can't play games from ur HD on LiVE

thanks for not flaming me guys..

my question is what is error 21... i read it in the tutorials (error codes explained)

"21 - anywhere - This error says that the machine was booted to display a error, basically someone told the machine to reboot (or launch a xbe) with this flag, and the error code just means its been rebooted by the flag"

only if there was a way around this.

Should it be something with the singned shit. So that the xbox doesn't recognize the linux.xbe (changed evox) as a normal program. So it doesn't allow it to launch. Maybe it requires a change in Evox. Or maybe the st.db needs a change.

i wonder what would happen if you got rid of the live install from the dash and left it as when you first bought your xbox? hmm.

I can't try that, i don't have the dasboard anymore without LIVE.

Its worth a try though. But it should also be possible WITH the LIVE installed. There has to be something changed in the exploit it think.
Because you can run linux, why doesn't EVOX work?

I'm going for a sleep now, going to work tomorrow on it @ my work. I have to work in about 6 hours.
Need my sleep......... ZZZzzZZzzzZz

Ok, I have been around the scene for awhile... in the background.  Searching and soaking up all the information that I can.

And after reading this article about the details behind the 007 save game hack and how it actually works. Click here to read article

I realized that we still need the "key" to be able to sign other apps to work with this exploit.  Because as most of you including myself have noticed, the font signature doesn't work when signing anything, including evox.

After reading the above article, this is what happens...

The buffer overflow happens, "... It then disables write protection in the kernel memory. It then proceeds to scan through RAM, looking for the last four bytes of the public key. Once it finds that, it modifies the last four bytes of the public key. Once you modify the public key this way, you end up with a public key that is easily factorable. It is now divisible by 3! This allows us to easily figure out the other prime, and from that then we can recreate the secret key used. "

So we need to figure out how this particular overflow works, and then figure out if it uses the same method as the 007 hack by changing the last 4 bytes of the signature.

hrm... has anyone tried signing evox(which you have to rename linux.xbe) with the 007 signature and testing to see if it loads?

I might have to try this to see if they just copied that part of the code...

I am at work now I will try it once I get home.

We need to work as a team to figure this out.  Those this MAY mess up peoples abilities to listen to music while playing games, it seems like the way to go until the issues with the font exploit are resolved.

I will keep you all posted.  Also any that knows different please correct me if I am wrong about anything I have stated.

I tried that already, its not working. I already tried also to load the freex EVOX and renamed it to linux.xbe, but also not working. Keeps up popping error 21

Every thing I sign fails, I got the linx.xbe that came with the hack working, I think it is the signer I am using, can someone give me a few hints to where exactly they found theirs that has been seen working, I rename the out and everything. Any pointers in the right dirrection would be nice.

I still can't understand. If its possible to launch Linux from it, why isn't it possible to run EvoX? My knowledge is not good enough to find it out. I Still not understand it. Everything i sign it still give's me error 21.

The reason why xbedump doesn't work to sign any of the files is because it's not MADE to sign anything for the audio xploit.  The guy never released the key he used, he just released his linux file and the st.db file... unless somebody opens that up or the linux file and checks what key is used and then implements that into a new xbedump program, you're not going to get it to work...

I never saw the key floating around, I just assumed since the switch existed for it, that it was in there, I was abuot to ask for they key and just compile my own, thanks hoopter, I aint good at hashing out keys, be nice if someone looked at this a litte It doesnt look like he tried to convelude anything thuogh the files are small. I think it would be a sweet hack to launch something else.
