189w ago - As a follow-up to the previous Project PNM news, here is another update from PlayStation 3 hacker No_One below.

To quote: Hi mates, I wanted to give you news concerning the PNM project. I really missed time. But I just finished what I call the "stand-alone mode". In this mode, we can do everything concerning the NOR FLASH mangement.

Here are the functions working now:

  • copy memory
  • dump memory
  • update memory
  • display memory CRC32
  • read memory
  • display memory details

PNM is now working with 2 NOR sockets and 1 "virtual" one which is the PS3 embedded memory. It means for example that now we can dump/update the PS3 NOR like any flasher, but also copy its content to another FLASH and so on...

Next step now consists in wiring the PNM board to the PS3. This is what I call the "PS3 mode". I will do it next week

I will of course give you details, some nice pictures and maybe a video. We are not so far to be capable to dual firmware the PS3 and do some nice progress in FLASH decrypting.

Have fun !
Cheers

No_One

PS: For people asking why I simply didn't use a twice capacity NOR FLASH (32MBytes) instead of 2 NOR FLASH (16MBytes). This is simply because it is easy for SONY to disable the dual firmware feature using what we call the "Product ID". Original NOR has a unique product ID (16Mbytes). A simple check and you cannot anymore use PNM.

You know why modchips take time to research? Because its not as easy as throwing a switch, some flash memory, and a resistor on it and calling it a day. Anyone could have looked up the public datasheets for the flash memory 5 years ago and done this. Wanna know why they didn't? Because its dumb and it won't work.

Indeed but surely in the real application you'd use more complex circuit - at leas some additional capacitors or logic flip circuit controlled by pushbutton with LED indication etc. etc. etc.

Also - in regards of various FWs on hard drive - if anyone would go through all the troubles piggybacking the flash they can also have two hardrives and switch those (most probably only while powered off) also by a "switch" ...

I think its alright to kill a ps3 or two for the sake of the greater good.

Wow... Does anyone have knowledge of circuits? You CANNOT do a NAND or NOR dump while the console is in operation using hardware. It requires the console be off and unplugged and doing so while on could seriously damage (if not immediately fry) your ps3.

We know for a fact that there is a hole in that is possible to find by reversing how the spus work. Why can't we just get a couple of talented devs, who know how to reverse focused there instead?

The only real use i see in this is just to obtain the 3.61+ keys in order to boot newer games under some cfw ... be it a cfw or a mfw. Joe Shmo won't want to do this solution considering how involved it is. In fact ... since you have to ruin a ps3 (or find a bricked one) to even do this ... why not just keep one on ofw and one on cfw ?

If this aids in getting new fw keys and if all of the offsets are patched during boot-time ... then we might have very completely pwnd the system ... considering someone actually goes through the lv0 flash to get the new keys (every time a new ofw is released).

Either way ... seems much simpler to perform on a fat than a slim. I hope to see a 3.61 flash somewhere in the wild within a few days.

Is a software hack still going to be available for 3.6 or is it going to require an external hardware device?

Hooray some more progress! Now just disappear before Sony finds you!

But its great to see some more progress towards the 3.6x firmwares.

Really something to look forward to especially for this upcoming psp remaster thingies.

i took a review of this, think about it you need two ps3's (one to take apart n steel the flash) or find the same models flash memory and solder and make a switch on ur ps3, each flash can have its own firmware, BIG problem would be that a hdd that has lets say 3.55 cfw on the 3.55 first flash, the second flash 3.6+ will make you update threw that hdd.

BUT as an idea, spoofing the firmware on the hdd a possible compatibility will work., a big thought is since it is a theory, if the ps3 model and key is stored threw the flash/ then that will be the biggest problem since the ps3 key would be on the hdd, and the hdd would not match each flash. many possibilities and many chances of making the ps3 more hacked than the psp
