Le Downgrade De Ps3 Fat 3.6x Avec Une Infectus 2

[the-green]

On disait que c'est possible depuis longtemps mais personne n'a pu démontrer à la scène comment faire ça !

Désormais un hacker espagnol du forum Elotrolado vient de dévoiler une méthode hardware permettant de faire le downgrade de PS3 FAT en firmware officiel 3.6X, bien sur le but est de revenir en firmware antérieur afin de pouvoir utiliser un CFW 3.55 ou autre. Comment ? C'est "simple" (pour certains bien sur ), mais on a besoin de la fameuse puce Infectus 2 pour ça.

Cette méthode hardware de downgrade permet aussi de débrikcer les PS3 FAT comme ceux brické par le CFW waninkoko V1 à titre d'exemple. La solution et à première vue n'est pas adressée à tous le monde, bien loin delà, il faut être un expert en soudures puisqu'il faut réaliser des points de soudures très fins sur la nand, pour les plus curieux vous-voici la photo pour comprendre de quoi on parle:

Il faut bien noter que dospiedras1973, l'auteur de cette nouveauté précise qu'il a testé cette méthode sur une PS3 FAT avec une nand 256 MO, mais "théoriquement" elle devrait marcher sur les nand 16 MO, chose qui reste à vérifier à vos risques et périls.

Citation de dospiedras1973:

Hello, I've been working on this project about two months nowsince 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 almostthe same in those with normal flash, but because even I havemy fat fucking 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 asin 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

"

ay you will see that just under a very similar line, I find this datain the offset 000C0020 may vary according to the nand andthe party starts here:-D

EVEN replace that line with the file if you use the hxd1patchcos.bin get in the first 0 of the line -> right click and paste writing before you have to have an open 1patchcos.binhxd in hex ​​and copy its contents to can paste .[ps3hax.net]

"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 alsocojemos 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 thisdump 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 ourfactory jig to put it into service mode and put it in factory, thenthe 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 tolose 3.55 to 3.41 then you will have to put the pup up to 3.41before 3.55 or 3.55 will remain in that if cost will not rewrite thedump again to downgrade to lower the pup that you put thefirst time.)

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

Note: this applies to repair the brick Waninkoko NAND NOTDONATED plates even sem-001 (tested) (and stepdowngrade xD)
