Aside from the different hardware revisions of the PS3's motherboard, the systems are virtually the same as mentioned in previous posts. We have examined multiple PS3 TEST's, Retail PS3's, Demo Unit PS3's, and even Factory Mode PS3's, and found that there are no hardware differences between them at all.
Mind you, there are differences, but they are due to the hardware revision, not due to the systems themselves. To make that more clear, the units are identical to their counterparts of the same hardware revision.
So, the question is- what's the difference? Software!
We all know the difference is in the software, and after examining countless dumps from these systems, on top of flash dumps given to us by you, our loyal re... More »

It is a fairly simple process as follows.. For starters, the PS3 is powered off, and a special USB dongle, known as the Jig, is connected. The PS3 is then turned on, and then off, once it has detected the Jig.
After this occurs, the PS3 is then turned back on, into "Service" Mode. From here, the PS3 is re-flashed using a Firmware Update on a USB stick, specifically designed to only install from the Service Mode. Once the PS3 is re-flashed with the software, it is then used in conjunction with a PC running customized software, specifically the DEX.exe and CEX.exe's.
There are a multitude of special PS3 firmwares, basically three major ones. The first is a Core System, followed by the Service Sys... More »
The item that peaked his interest the most was that it had one single 56-pin Flash chip, the S29GL128N90TFIR2, and was 128MB in size in contrast to older PS3 consoles utilizing dual (2x256MB) 48-pin chips totaling 512MB. So, he bought a new adapter, and some blank chips and proceeded to pull the 56-pin flash, and dumped it.
To our surprise, he was unable to dump more than 16MB of it! At first, we believed that the other blocks in the flash were protected via password, however there was something else brewing.
He took the 16MB dump that was made and flashed it onto a completly blank chip, and reinstalled it in the PS3.
To our surprise, it worked!
Now, if you recall, newer version PS3 Firmwares have ask... More »
Please share ideas questions and feedbacks in this thread comments, it would be appreciated.
Download: PS3 NAND Flow Rebuilder v3.50 BETA
NDT ;-)
From ReadMe: PS3 NAND FLOW REBUILDER v3.50 (including ECC Algo by RPS).
This tool allows to unscramble the blocks of a PS3 dumps ordering them in a way that the dumps become readable and extractable!
It also allow you to re-scramble back to the original order once you modified the data you wants, then from now on it include the ECC recalculation algorithm that was private until today.
It's for study and tests purposes, for experienced people only (devs) that this way can manage the files inside the flashes and patch sensible areas.

First, a small technical explanation. We were not able to modify any data on the PS3's flash chips due to the ECC. The ECC is a checksum basically, that ensures whatever data is in the block is not changed or corrupted, and if it is it errors.
So, the problem was since when we tried to alter data, the ECC would then in turn be invalid, causing errors, making the system not boot.
We did develop a way around this, however, it was time consuming and quite slow. We used the PS3 to write data to the flash, then dump it, with its proper ECC, then rewrite to where we needed it. This would take hours on end! We were not able to regenerate the ECC since we did not know the proper algorithm.
But now, we can!!
After multiple tests done by NDT to see what the ECC... More »
To begin this week's PS3 Dev briefing, we want to give a follow-up in regards to the PS3 Downgrade PUP's for PS3 TEST/Debug consoles we recently acquired.
Yes, it does work fine, and we have successfully downgraded a PS3 Test to version 1.00! Version 1.00 is quite neutered for a TEST, about the only thing that works is the ability to run code from a DVD/BD, aside from that just about everything is non-functional.
More to come in those regards, including our ability to install and dump Retail PKG's on a Debug PS3 console!
Now onto the rumors: As we all know, many have been trying (but failing terribly) to dump the EEPROM chip inside the PS3's controller.

First off, we would like to wish all of our American visitors a very Happy 4th of July 2008 today!
But for more explosive news (who doesn't love a pun?) we recently received two special PS3 PUP files from a VERY nice guy. As pictured below, they are PS3 Debug 1.00 (65.5 MB (68,765,224 bytes)) and PS3 Debug 1.50 (72.2 MB (75,762,080 bytes)).
These PUPs, which are the special downgrade PUPs, allow a user to downgrade their PS3 TEST from any version down to it. For example, with the 1.00 SPECIAL Downgrade PUP a user can be on 2.40, install it, and after a reboot be on 1.00!
1.00, which lacks just about every feature but ON/OFF functionality, will then let us upgrade to any DEV firmware above it.
Which brings us to 1.50... Through examining numerous Sony documentation recently, we have read that in the 1.60 Firmware the PS3's kernel memory and user memory are separated, leading us to believe that the kernel m... More »

The wait is finally over for those anticipating the day PS3 Firmware 2.40 would be available.
A few weeks back, we posted a video of PS3 Firmware 2.40 Debug in action on a TEST PS3 unit, and more recently Sony confirmed the PS3 Firmware 2.40 Update's Features (including detailing which titles currently offer Trophy support), along with an Official PS3 Firmware v2.40 FAQ.
