Dumping PS3 Hypervisor and Bootloader with Atmega8 at 16Mhz

Sponsored Links
263w 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.

I've just order all I need to make this assembly, but i've two questions:

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?

Atmega chips are also cheap and available everywhere. Just requires some effort to build and flash.

This is much cheaper and easier solution than using FPGA's like geohot.

personally, i think it would be priceless to use a mac keyboard and exploit, disable one of the led's (oh.. scroll lock num lock caps, take yer pick..] .. have modify the exploit code so that you have to type in glitchitnow [and hit say scroll lock -led you disabled] .. and away goes your 40ns pulses .. until say release key, and, also have the benfit of useing the keyboard on the ps3 to boot' instead of 1 usb connection, be additonal one .. one hack for another..

so.. who's up to do this one.. [personally i think GeoHot should, just to give the finishing touches on what he started] anyone for bets on the ramifications news wise on that one? lol...

Hi guys. Just got my 555 and 4025. I know it was said to be impossible to achieve 40 ns but do I have any chance?

I routed the wire the same as on xorlosers blog (Make sure you are not shorting out the resistor with bare wire over the top of it).

My wire actually comes from the same point (but from the right) then is routed through the gap between the column of components (just underneath the brown capacitor)

The length of the wire would be about 6 inches or so.

I make that < £3 How cheap do you want?

IsoMick, How did you route the connection from the system board out of the ps3?

I have tried 3 different routes and everytime I tru to boot I get either a blacnk screen or an alert 0 and then hang.
If I remove the wire from the resistor it boots just fine. This drives me nut !!!
A picture wouldn't hurt if you have one.
