Thanks a lot CJPC!!! But can you show your one? What did you use?
how many times you press Button to get exploited?

I'm sure somebody can write a simple program to send whatever that button does at a much higher frequency that the human hand can. "Just do it"!

ok CJPC i will try your diagram so IT WiLL WORK i believe! i will write later some progress!

No surprise here since it was released before the exploit, but to quote: http://twitter.com/Mathieulh/status/8643140668
I just wanted to confirm to anyone willing to try geohot's hack on the ps3 that it does work on 3.15 (it has been tested)

I don't know if this has already been asked, but can the 50ns low pulse be achieved by using a pic chip (12F629 or similar) and a bit of code to trigger the pulse instead of using a switch?
As mentioned earlier, transistors are much faster than tactile buttons. Could this be done?
For example: PIC 12F629 that pulls an output low for 50ns, but does this say 4 times a second? Surely this would result in more 'hits' for the exploit?
Correct me if I'm wrong.

Well - in theory yes it would work, assuming you can find a PIC that can handle the job fast enough (and, make up some code to whip on there).

for whoever is using his circuit, you have to keep the trigger held at 5V UNTIL you want the pulse to go through, and then let go of the button (if you're using a momentary switch / pushbutton). quite frankly i feel like the pulse width may not be the deciding factor as to why everyone is having issues with the glitch working. if CJPC was able to get it to work twice, i feel like a difference of +-5ns isn't significant, but rather it's the fact that when people think it SHOULD be triggering, it isn't.

I believe you are right at far as the way the 555 is wired I think it should be wired in astable mode http://en.wikipedia.org/wiki/555_timer_IC it uses two resistors and continually pulses on a specified frequency also I dont think that you need HEF4016 also the wiki page provides a formula to calculate the time of the pulse LOW=ln(2)*R2*C(in Frads (F) im not firmiliar with the ln value but if someone with better electronic knowledge wants to comment I think we could figure a smaller easier to source (all Radioshack parts) pulse "generator".

Well - Gave the altered diagram a try (2+6 to the switch) - also had no luck. Open to suggestions on some modifications, if not we are going to have to get a bit more creative.
If I had to guess, it seems like conee might be onto something, as in the switch not totally triggering properly - however the PDF does not seem to agree - says to pull the lines high for a low pulse, then again - nothing seems to agree!
