Downgrade 3.6x : Le bout du tunnel?

[Vous devez être inscrit et connecté pour voir ce lien]




Dospiedras1973, des forums espagnols ElOtroLado, vient de publier quelque chose qui va ravir les possesseurs de PS3 FAT (NAND de 256 MO) en Firmware 3.6X. Par ailleurs, cette méthode permettrait de débricker les PS3 FAT qui ont subi un brick causé par le CFW Waninkoko v1. La méthode consiste à souder une puce Infectus sur la PS3. Ceci est donc réservé à ceux ayant l'habitude d'utiliser leur fer à souder et qui sont expérimentés.

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

“00 00 00 00 00 00 00 00 00 00 00 00 00 6F FF E0”

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 )

Thanks to:

all channel # irc-hispano darkps3 for supporting me for so long
to donate the INFECTUS austaquio32 to achieve to continuewith my project
to Nodial2ne paid for the help locating files in the nand
to robs1 for helping throughout the process with ideas tomake this possible
and everyone who was patient and not by private haunts mexD

Voici les PS3 compatibles :

CECHA = 256MB
CECHB = 256MB
CECHC = 256MB
CECHE = 256MB
CECHG = 256MB

Merci à JackL pour l'info.

J'ai pas trop compris le but de faire çà (noob que je suis )

Ben le but premier du downgrad des consoles c'est de pouvoir revenir en firmware jailbreakable( 3.41,3.42,3.55 etc.)de ce fait installé des homebrowes, la par exemple installé un FTP pour relié avec l'ordi et insérer un patch hack sur MW2(exemple)

ah ok, Merci de l'info :)
