Dumping PS3 Hypervisor and Bootloader with Atmega8 at 16Mhz


Sponsored Links
237w ago - Hi guys, I used an Atmega8 running at 16Mhz (I had a couple lying about from the BT Vision project I was working on) and knocked up a small prog to do the same as the other chips and dump out the PS3 Hypervisor and Bootloader.

I was quite surprised, It actually worked fairly straight away! I only had one pulse going everytime I pressed the button at first but not a lot was happening.

So I did what xorloser did, and modded it so it pulsed every 100ms while the switch is pressed.

After about 30-40 seconds... I got a hit with the exploit code posted [Register or Login to view links]. Then I used the dumper (posted here) to dump the 10mb bin.

Just having a look through the dump, lots of strings in there.. I haven't dropped it into [Register or Login to view links] yet tho...

This is the source and hex (for those who dont want to compile it) for the Atmega8 which I glitched my PS3 with. The Chip I used was the Atmega8-16pu. You will also need a 16mhz Crystal, and 2 x 22pf Capacitors.

Grounding pin 14 on the chip will produce a pulse on Pins 2 of the chip (infact it does all of PORTD) This should then go to the memory bus point on the ps3. See Circuit diagram (below).

I used [Register or Login to view links] to program my chip, with CKOPT ticked in the fuse settings, everything else was unticked.

The links posted for the PS2 wiki are an interesting read, just a little peak at some of the stuff that the dev's must be looking over now

And well done is0mick, +Rep!

It seems like Geohotz's exploit really did ignite the Ps3 scene!
Definitely... I'm sure in weeks or months to come a lot of the "whispers" that are currently happening behind the scene will surface publically if they prove true.

There are already unconfirmed reports that the exploit is reproducible on PS3 Debug units via XMB with no memory line glitching required through software which would be interesting.

Other rumors include calls like cellUsbdAllocateMemory and libusbd may be exploitable, but right now these are just IRC rumors and remain unconfirmed.

Slowly the PS2Dev Wiki is being updated also, something to keep watch on:
