Dumping PS3 Hypervisor and Bootloader with Atmega8 at 16Mhz


Sponsored Links
244w 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.

I've rebuilded xorloser hardware with a Attiny2313 at 25MHz at the past Weekend. But I could not test it yet. maybe next weekend

You can download the package here: [Register or Login to view links] Sorry, all in german

The Download link is at the bottom of the Page. Source Code + Circuit are included.

Costs about 3,50 Euro. Your opinions would be nice.

I wounder if I could do this by connecting a Signal generator that generates square waves at a frequency of 25MHz. I will do a quick test tonight with some SMT clips.

Does anybody know if there is a difference in f/w between the different regions ?

My PS3 is a Hong Kong version with REG A blueray and reg 2 dvd.
