May 23, 2011 // 1:41 pm - Today anonymous PS3 hackers who call themselves No_One have released a Dual Firmware PDF document that may bring 3.6x+ Key Decryption and new CFW to Custom Firmware fans.

Download: PS3 Ed2.pdf / PS3 Ed2.pdf (Mirror) / PS3 Ed2.pdf (Mirror #2) / PS3 Ed2.pdf (Mirror #3) / PS3 Ed2.pdf (Mirror #4) / PS3 Ed2.pdf (Mirror #5) / PS3 Ed2.pdf (Mirror #6)

To quote: 05/23/2011 For Immediate Release: The beginning of dual-firmware PS3: PS3_Ed2.pdf The technique outlined in the .PDF will help people learn more about 3.6x firmwares.

The solution relies on the implementation of a second NOR/NAND Flash. Some technical limitations have been identified. But time will help us to remove them.

The information in the document is still theoretical for the moment, however please post results from your testing.

We believe knowledge and information wants to be free. Learn what you can and help contribute to making the PS3 scene a better place. Released by No_One.

This does look promising. looking over the images I can see its made well and I would imagine its only a matter of time before the developers find a safe outlet for it. Just not in the usa because you get 20 years. lol

I think this is something similar to the usb black-cat flasher once used to flash bcm chips using a jtag but with added breakout. you can see from the 1st image its connected with usb and jtag.

Even if it never gets released from them, we now have the means of making one ourselves, just a little different than the old lpt1 home made jtag lead.

When could PNM be released? Anyway good job that would be awesome

Here is another update from No_One on the hardware for this project which should allow developers to further examine the PS3 NOR flash in search of new exploits:

Anonymous hacker releases explanations of DUAL NOR hardware.

A hardware has been designed. Project codename: PNM (PS3 NOR Manager). It meets the following requirements:

  • copy/dump/update NOR FLASH
  • static switch and dynamic switch between 2 NOR FLASH (sockets)
  • realtime spying the NOR activities

A PDF with all the explanations, schematics and so on will be provided very soon for release ! ...this is one of the page extracted from the PDF that will be released. This is a part of the PNM schematics:

I believe knowledge and information wants to be free. This is why I consider that this project is open-hardware and will be open-source !

PS: PNM could lead to 3.6x+ key decryption/CFW, but also to a TRUE dual firmware management
PPS: No other hardware (Infectus...) will be capable to handle what PNM is capable to do...

In related news, some install pics from dospiedras1973 are posted here:

Finally, Varicela via DemonHades ( shared a pic of another PCB with Dual NAND support allowing users to install both PS3 OFW and CFW on a single console, stating (roughly translated) that there are integrated sockets on the "two side plates" that are to be used by the Infectus modchip–for this dual-NAND to work.

this is good news.

Even if this is possible, it would require a hardware mod and also another mod to allow switching between 2 hard drives. Different firmware versions probably handle data on the drive differently (especially on the newer console versions with small nand size since a good bit of the OS is stored on the HDD instead of the nand).

Basically all this really means is that there may be a possible alternative (hardware mod + 2 HDD mod vs buying a 2nd PS3 for OFW).

So really this won't gain anything. It won't lead to CFW. And if your willing to buy the extra parts and mod the PS3, your much better off just buying a 2nd PS3 for official firmware.

So nothing interesting really... move along people.

Didn't the consoles with 256Mb flash use it for filesystem / OS? Something along the lines of merging the 2 partitions (128Mb + 128Mb flash = 256Mb partition)

There were people having trouble with the CFW in the early days. The 16Mb NAND consoles & the 256Mb NAND consoles?

It's been a while...

I thought the Fat Ps3 already had 2 Nand (Or some other flash memory) used to store the firmware and a copy of it in case something goes wrong?

I can't remember where did I read that (or even if it is true ^^ ), but that's what I immediately thought when I read that news. I suppose that in that case we could use the "backup" flash memory as a second firmware, enabling Dual Firmware.

Does anybody have an answer on these? Again, I might be completely wrong

i used this method on my amiga 500 ... bootrom 1.2 and 1.3 , chip selected by the chip-select-lines.
