It's a huge day for the PlayStation 3 homebrew scene. Developer NDT has released the PlayStation 3 Rebuilder v3.50, which lets you unscramble the blocks of a PS3 dump to make them readable and extractable. It even allows you to re-scramble it.

One can only speculate as to how this would affect the PlayStation 3 homebrew scene from here. Here's the readme from NDT.

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.

In this updated version you'll find some good news:

1) You can now re-scramble back a modified dump in order to flash it in your console (ECC regeneration is now included).

2) Analyzer has some more informations (it's still alpha, i use it for debug, it's complete only for versions 2.40/2.41).

3) It automatically extract EID file in its own modules.

4) It show the (eventual) differences between the 2 bootloaders files

5) Save Console Attributes log file in the Log dump folder.

6) Support the 80 Gb Nand Dump extraction for study purpose (nand model is different and is one chip only).

USAGE:

- UNSCRAMBLE & INTERLEAVE FLASHES / RESCRAMBLE & DEINTERLEAVE FLASHES -

First of all select if you want to unscramble or re-scramble your dump.

The first option is the first you have to use, it unscramble your flashes and interleave them in order to obtain a readable and extractable dump.

Once you modified the unscrambled dump (you can swap files or change some data) the second one allow you to deinterleave the flashes rescrambling them as the original ones are (otherwise dump won't work).

- BYTE REVERSE AND EXTRACT AN 80GB DUMP FILE -

Our very own Courier dumped a 80Gb Flash yet! It's completly different from a 40/60 Gb dump, it's already interleaved.

With this option you can extracte the kernel files from this kind of dumps.

- FILE SELECTION -

"Flash 0" (TOP): Is the flash0 dump file, warning, many USA dumps use the way around names, so if your dump is USA you should try to load Flash1 here instead.

"Flash 1" (BOTTOM): Is the flash1 dump file, warning, many USA dumps use the way around names, so if your dump is USA you should try to load Flash0 here instead.

OUTPUT (INTERLEAVED) file: It's the interleaved file that the tool produce using the UNSCRAMBLE option.

INPUT (INTERLEAVED) file: It's the modified interleaved file from witch the tool rebuild the new flashes (0/1) that you need reflash on PS3.

- ANALYZER -

It's the option that add to the log what's contained in the flashes blocks, the info is in this format:

0000000000.00.01.120.15140.00000#0249 | 00000000.0.1.78.3B24.0000 ==> File-System Root

On the Left there is the OOB block unique data, on the right (after the ==>) there is the analysis, so what the block contains.

It's fully working only for dump versions 2.40/2.41 and it's very slow, it's an alpha debug option.

- GENERATE NEW ECC -

Using the Option "Re-scramble modified dump then de-interleave it into two new flashes." you can enable this flag, so the new modified and rescrambled flashes will have ECC fixed (thanks to RPS for the Algo).

- FORCE BAD BLOCKS ECC CALCULATION -

This option shouldn't be checked unless you know what you're doing!

PS3 don't expect the ECC of a bad block to be good, it's safer to keep it as it is.

- GENERATE AMOXIFLASH DIFF FILE -

Bushing is working on a feature for Amoxiflash (a tool to flash nands fo Wii, XBOX360 and PS3) that will allow you to flash only the differences from the original flash file.

This will allow you to save time while trying some ps3 hacks attempts :-)

INSTALL NOTE:

This tool need the .net framework 2.0 in order to work: most computers should have it installed yet, by the way here is the link in case you wonder where to get it:

microsoft.com/downloads/details.aspx?familyid=0856eacb-4362-4b0d-8edd-aab15c5e04f5&displaylang=en

NOTE:

ECC calculation (Algo by our very own RPS *you mate rocks!* ), is included in the tool this time, have fun pathing your firmware.

Stand-Alone tool (PS3NANDECC v1.30) was included in order to be used separately if you wish; The Algorithm is the same for Debug and Retail consoles.

###BEWARE: you need the external power addition to your Infectus mod in order to use it! Otherwise it's to risky, if you patch something bad your console won't boot anymore.###

And a huge thanks to NDT for sending in the tip!
