== Accessing the NAND ==


Power the Infectus, it crashes the PS3 and leaves the NANDs in powered mode:


== NAND Offsets ==
Use the console to power the NANDs: power it up until the PS3 crashes and halts with red flashing LED, press power again to stop the flashing, but keeps the console powered on. The NANDs are not accessed by the PS3 in this way, so it doesn't matter if the NAND content is already messed up. After that, you can read/write the NANDs.


===1patchcos.bin===
Use the Infectus to read the 2 different NAND chips. You get 2 files this way, one for each NAND : flash0.bin & flash1.bin
CTRL-F : <code>00 00 00 00 00 00 00 00 00 00 00 00 00 6F FF E0</code>


CECHC-04/COK-002 MFW 3.15 ([[User:Euss|Euss]]):
Interleave the 2 previous mentioned bin files into 1 single flash dump: flashfinal.bin (256MB)

Hola , llevo trabajando en este proyecto cerca de dos meses y ahora mismo ya que he conseguido que funcione lo publico para que todo el mundo pueda usarlo, este tutorial es para consolas con NAND flash de 256mb , no significa que no funcione en las de 16mb , en sí se modifica casi lo mismo en las que tienen nor flash , pero debido a que aún tengo jodida mi fat 80gb de 16mb no lo he podido ni probar ni verificar.

Con infectus sacamos nuestra nand flash0.bin y flash1.bin y como en el tutorial de lukin para reparar las bad nands hacemos el mismo proceso hasta que obtenemos nuestro dump flashfinal.bin de 256mb
  000C00E0  6C 76 32 6C 64 72 00 00 00 00 00 00 00 00 00 00 lv2ldr..........</pre>
 
esta nand la abrimos con un editor simple hex editor y buscamos esta parte
 
"00 00 00 00 00 00 00 00 00 00 00 00 00 6F FF E0"
 
vereis que justo debajo ay una linea muy parecida , yo estos datos los encuentro en el offset 000C0020 , puede variar segun la nand y aqui empieza la fiesta :-D
 
reemplazamos INCLUSO ESA LINEA con el archivo 1patchcos.bin si usais el hxd poneros en el primer 0 de esa linea ->boton derecho y pegar escribiendo , antes teneis que tener abierto el 1patchcos.bin en el hxd y copiar en hex todo su contenido para poder pegarlo..
 
luego vamos a buscar el segundo archivo a parchear buscamos en el hxd en nuestro dump la parte :
 
"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"
 
y de la misma manera que se parchea el primero se parchea este también , cojemos el archivo 2patchtrvk.bin del pack y reemplazamos todo el contenido incluso el "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"
 
luego cogemos con el flowrebuilder usamos la opcion reescramble this dump para que nos vuelva a generar nuestro flash0.ECC.bin y flash1.ECC.bin
 
y flasheamos el resultado , cuando termineis notareis que la ps3 ahora enciende pero tiene un bonito black screen , vale cojemos nuestro jig para ponerla en factory service mode y la ponemos en factory , luego cojemos el tipico lv2diag de marras y el pup que querais
 
( AVISO : el primer pup que metais se quedará en la consola como la versión minima que podeis downgradear luego , por si quereis bajar de 3.55 a 3.41 luego tendreís que meter el pup 3.41 antes de subir a 3.55 o se quedará en 3.55 por que si no os costará volver a escribir el dump de nuevo para poder downgradear mas bajo del pup que pusisteis la primera vez. )
 
luego poneis el lv2diag para salir del factory service y ya está ;-)
 
Notas : esto vale para reparar el brick de waninkoko SIN NAND DONADA incluso en las placas sem-001 ( probado ) ( y de paso downgradeas xD )

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 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):


'''revoke package:'''
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
for a 3.72 console it would be : 00 00 00 00 00 00 00 20 00 00 00 00 00 00 00 20 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 60
http://pastie.org/3006911


'''revoke program:'''
nand we open this with a simple hex editor and look for this part editor
for a 3.72 console it would be : 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 E0

ay 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:-D
 
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 DONATED plates even sem-001 (tested) (and step downgrade xD)
 
Thanks:
 
all channel # irc-hispano darkps3 for supporting me for so long ;-)
to donate the INFECTUS austaquio32 to achieve to continue with my project
to Nodial2ne paid for the help locating files in the nand
to robs1 for helping throughout the process with ideas to make this possible
 
and everyone who was patient and not by private haunts me xD


Example, copy ros1 to ros0 and overwrite (HxD):


* goto edit
pack:
* select block (CTRL-E) : start 7C0020 - length 6FFFE0
* copy (CTRL-C)
* goto (CTRL-G) : C0030
* overwrite (CTRL-B)

==== PUP to use ====
pd: I have 4 years unemployed, who selflessly want to donate something please contact me via private (sorry but I have 2 children and the PS3 does not give me to eat me or them xD)
[[Talk:Downgrading_with_NOR_flasher#Premade_CFW_Rogero_V2| Rogero V2]] or any firmware with prepatched lv1 (no syscon hash checks)
either that or give me a job lene!

* if using the jaicrab NoBD lv2diag : Use the Rogero normal PUP
