New method Downgrade v2 supports all NOR FLASH
Write a new method consisting of 6 patches, this time we will use to edit the dump hxd original of your PS3 (make backup)
steps:
first check if our standards Dump bytereversed, to start patching the original dump.bin file we must first ensure that the beginning of the flash at offset 200 is readable "IFI" if instead you see "FI.I "Your rules need to patch it bytereverse before (a and go back to him to put it in bytereverse the console to be read again" FI.I "when we patched the files and offset's a patch are these
patch1: OFFSET 0C0010
Patch2: OFFSET 7C0010
patch3: OFFSET 80000
patch4: OFFSET A0000
Patch5: OFFSET 40000
patch6: OFFSET 60000
easy, normal and cojemos the patch1 for example, copy content and paste it patch1 0C0010 writing and so the rest (the file size does not vary after the stripe)
the rest of the downgrade is the same as before, factory mode, and pup jaicrab lv2diag nochecks.pup of the previous release.

Downgrade v2 Nuevo metodo compatible con todas las NOR FLASH
Notapor TwoStone » Mié, 31 Ago 2011, 16:13
Escribo un nuevo metodo que consisten en 6 parches , esta vez vamos a usar hxd para editar el dump original de vuestra ps3 ( haced copia de seguridad )
pasos:
primero revisar si nuestra nor dumpeada está bytereversed , para poder empezar a parchear el archivo dump.bin original primero tenemos que asegurarnos que al principio de la flash en el offset 200 se pueda leer "IFI" si en vez de eso veis "FI.I" vuestra nor necesita bytereverse antes de parchearla ( ay que volver a hacerle bytereverse al meterla en la consola para que se pueda leer nuevamente "FI.I" cuando la tengamos parcheada los archivos y offset's a parchear son estos
patch1 : OFFSET 0C0010
patch2 : OFFSET 7C0010
patch3 : OFFSET 80000
patch4 : OFFSET A0000
patch5 : OFFSET 40000
patch6 : OFFSET 60000
es facil , cojemos la nor y el patch1 por ejemplo , copiamos el contenido de patch1 y lo pegamos escribiendo en 0C0010 y así con el resto , ( el tamaño del archivo no puede variar despues de los parcheos )
el resto del downgrade es igual que antes , factory mode , lv2diag de jaicrab y pup nochecks.pup del anterior release.

Just extract the folder “downgrade v2 ProgSkeet” anywhere on your PC.
Open WinSkeet40000/LinuxKeet/iSkeet on your computer.
Create a dump of your 3.70 OFW if you haven’t already done it.
Call it “OFW370.bin” -IT MUST BE A BYTESWAPPED DUMP!-
Open the “Patcher” tab and select “OFW370.bin” as the input file.
Select the progskeet_patch.txt as the patch file.
 
This release is based on the patchset of the downgrade v2 released by dospiedra,
and you should check BYTESWAP while reading NOR and when you flash your downgrade.bin
file back. Go for it :) Now you have a fully working downgrade.bin to flash
