June 28, 2011 // 9:35 pm - Today dospiedras1973 has shared a PS3 Firmware 3.6x downgrade method for 256MB NAND (Fat) consoles via the Infectus PlayStation 3 mod-chip alongside a Waninkoko CFW Brick Fix followed by a New Method - PS3 Downgrade v2 Supports all NOR Flash from TwoStone.

Download: PS3 Firmware 3.6x Downgrade via Infectus / PS3 Firmware 3.6x Downgrade via Infectus v2 / Waninkoko Brick Fix Guide

To quote, roughly translated: Hello, I've been working on this project about two months now since I've gotten to work as public so that everyone can use, this tutorial is for consoles with 256MB NAND flash does not mean it does not work in 16MB in itself is changed almost the same in those with normal flash, but because even I have my fat 16mb 80GB I have not been able to neither prove nor verified.

Nougat (the phrase I owe to some forero around here that I really liked the expression):

With INFECTUS flash0.bin and we get our nand flash1.bin as in the tutorial to repair bad lukin nands do the same process until we get our dump flashfinal.bin 256MB nand we open this with a simple hex editor and look for this part editor:

"00 00 00 00 00 00 00 00 00 00 00 00 00 6F FF E0"

You will see that just under a very similar line, I find this data in the offset 000C0020 may vary according to the nand and the party starts here

EVEN replace that line with the file if you use the hxd 1patchcos.bin get in the first 0 of the line -> right click and paste, writing before you have to have an open 1patchcos.bin hxd in hex and copy its contents to can paste.. then we find the second file to patch at hxd we dump on our part:

"00 00 00 00 00 00 10 10 00 00 00 00 00 00 10 10 00 00 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 40"

And in the same way as the first patched patched this also cojemos 2patchtrvk.bin pack the file and replace the entire contents including the:

"00 00 00 00 00 00 10 10 00 00 00 00 00 00 10 10 00 00 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 40"

Then we take the option we use reescramble flowrebuilder this dump so we rebuild our flash0.ECC.bin and flash1.ECC.bin and flash the result, when you finish you will notice that the PS3 now has a nice on but black screen, it cojemos our factory jig to put it into service mode and put it in factory, then the typical cojemos lv2diag of yore and the pup you please.

(NOTE: the first pup that metais will stay in the console as the minimum version that you can downgrade then, if you want to lose 3.55 to 3.41 then you will have to put the pup up to 3.41 before 3.55 or 3.55 will remain in that if cost will not rewrite the dump again to downgrade to lower the pup that you put the first time.)

Then you put your factory lv2diag to leave the service and you're

Note: this applies to repair the brick Waninkoko NAND not plates even sem-001 (tested) (and step downgrade )

Good news

I think this method requires 3.55 on the ps3 to begin with before upgrading to 3.70 though, so then it can be stored to the ProgSkeet and then reapplied after an upgrade has occurred - kind of like a checkpoint for the Firmware to restore to.

Next step probably is going to be Dual Firmwares enabled via something like this, although I suppose most people would want a usb version lol

now that this has been accomplished, i think that all 3.70 games will also be playable on 3.55 via patches. *crossing fingers*

i can't find it for sale in australia..

Someone previously posted a link to a website called oz3ds that was selling it for something like US$66 with free shipping (I think it said that it was an Aussie based store).

Think I read in the past that the smaller nand versions have parts of their firmware stored on hdd. So is it now just about to adapt it to the smaller nand size or will we get in trouble cause of the external storage of some part of the fw on hdd?

If you got any infos about that fact, pls let me know!

it depends, which motherboards your comparing.

No, I don't believe. Did he go in FSM with a simple dongle on 3.70? I think it isn't possible because from 3.60 you cannot more use jailbreak to go in FSM.

But to downgrade from 3.60+ using a flasher you need to be in fsm or you have to patch lv1. However I'll wait for more explainations from dospiedra, this news (and 3.55 modded) are very interesting!!

ps: uf6667 said "Also big surprise also for 3.56-3.70 users "
