PS3, Exploit, Roll-out

[original version]



It seems that to roll-out the exploit and make it success 100% is like the lotery, don't get exasperated.

Once installed as descrived previously I recommend a restart. As it is so "tricky" to success with it, it is recommended to do it just after a restart and without logging in into the graphical interface. I mean, when the system requests our login data we will go to a terminal by pushing Control+Alt+F1. There we login with the user defined during the installation.

Once logged in we can go as root with the following command "sudo -s". WE introduce the root password and we are ready to test the exploit.

The command to run the exploit is "ps3exploit" and it needs a parameter. The amount of times that it will give you the opportunity to cause the failure to the hypervisor and that we will take advantage to generate the memory dumps.

If we run "ps3exploit 100". We will get 100 opportunities to carry out the deed.

It will show a message telling us to push the button of the circuit and the retry count until you to the 100 retries xD. How we will know that it works? If the exploit detects your button push in the circuit you will realize, the RAM dump will begin. And what happens if it is not detected? It will inform you that you got you 100 retries and that's it. If it is not detected don't despair, try again with "ps3exploit 100" until you get it.

In my case, I still haven't been able to make it work. I think that it is because of the circuit, I have not built it in the right way, the 26Mhz crystal as I previously said o the the circuit isn't the right one.

I'll keep you updated...

PS3, The 40ns circuit, Lets build it

[original version]

FAILURE



Just got the material, after 3 hours of search in a nearby "town". Anyway I haven't found the 25Mhz crystal, so I have to use a 26,770Mhz one (I hope that the history doesn't change too much :S).
Just tell you, that the sum of all of the components, including the board with the holes, hasn't exceeded 3€.

This afternoon-night-early morning I'll put my shoulders to the wheel. I'll keep you informed.
-----------------------------------------------------------------------------
It's 22:10 and I already have part of the circuit built. Some easy to solve doubts appear:
I have to supply 5V to the integrated circuits. I have located the power supply points from where I can get that voltage. I still have to locate the 3,3v points.
The attendant from the shop has given me the wrong resistors :S, so I had to put a few more in a serial way.
Right now the circuit looks like this:





---------------------------------------
Finished circuit.



Next step, Install linux (almost there) and solder the circuit to the PS3.

PS3, The 40ns circuit

Good night.
Tomorrow afternoon I'll buy the components to build the following circuit:



When back from shopping I'll build it. I'll describe the steps (while I study it :S).
