Dumping PS3 Hypervisor and Bootloader with Atmega8 at 16Mhz


218w 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 here. 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 IDA 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 ponyprog to program my chip, with CKOPT ticked in the fuse settings, everything else was unticked.

You could take 5V from the USB port and add a resistor. AFAIK the AVR can operate at 5V, too - check the data sheet.

And yes - the connection between Vcc and GND shouldn't be there. That mistake was pointed out to the author on the first two pages but it looks like he didn't provide a fixed schematic afterwards.

In my opinion, the 3.3V is not send to the ps3, it only feed the avr (there is normally no power send to the ps3, only a link between the xdr and the ground is made)

I've seen someone talking about a MAC modded keyboard, I've already told about a modded keyborad (not a MAC one indeed) to speed up things but seemed no one had the wish to wreck a 5$ keyboard to perform the hack with a bit more ease...

Furthermore, rereading I've seen now many ones talking about 3,3V... but... XDR of PS3 works on 1,8V, it's not that feeding it a 3,3V pulse could set up a big mess into it ?

I hadn't see that there is a new method Thanks you for the information !

But now i've order the atmega8, i will be happy if i can make it working too.

Hello, sorry for upping this old thread.

I've just order all I need to make this assembly, but i've two questions:
- Is it normal that the ground and the +3V are linked ?
- Where do you take +3.3V ?

Thanks you a lot.
There is a new method that uses LPT which is way more cheaper and easier. Why don't you use it?
