un membro di nome Judges del gruppo ps3hax sta lavorando ad un progetto sulla base del miglioramento del codice di Marcan del team FailOverflow poter flashare le Nor delle ps3.....dai primi suoi test è emerso che sia riuscito ad effettuare un downgrade da OFW 3.61 al CFW 3.55
vi riporto quanto da lui descritto:
Hi there..
Here comes my initial release of a NOR flasher soft for the PS3 called “NORway”. I know, there are other “WIP” projects, but I got a little impatient, so I’ve decided to create my own solution. It’s a port of “noralizer” by marcan, a pretty good working NOR flasher implementation for another FPGA board.
Anyway, here’s the README.txt, which should explain everything:
NORway v0.1
This project has been ported for the Teensy++ 2.0 from the original NOR flasher tool
(“noralizer” by Hector Martin “marcan” <hector@marcansoft.com>) that was used to flash
AsbestOS onto the demo PS3 at 27C3, and for experimentation.
Contents:
teensyNORway.avrsln – Source code for the Teensy++ 2.0 (AVR Studio 5.0)
teensydefaultNORway.hex – Compiled hex-file for the Teensy++ 2.0 (AT90USB1286)
hwinstallinstall-*.jpg – Some pics of how I’ve mounted the Teensy (CECH-2504A/B)
hwinstallnor_testpoints.png – Connection diagram of the NOR testpoints (CECH-2504A/B)
serial_install.exe – Teensy serial drivers for Windows
README.txt – this file
NORway.py – PC Python client
Hardware connections (see “hwinstallnor_testpoints.png”):
PS3 Teensy
A0-7 PF0-7
A8-15 PA0-7
A16-22 PB0-7
D0-7 PD0-7
D8-15 PC0-7
CE# PE0
OE# PE1
RESET# PE4
WE# PE5
RY/BY# PE6
TRISTATE# PE7
GND GND
There are no modifications to the Teensy itself required. Don’t install any power regulators,
don’t cut any traces.
DON’T CONNECT THE VCC SOLDER PADS TO ANYTHING!
Connection diagrams for other boards can be found at:
http://ps3devwiki.com/index.php?title=Hardware_flashing
Prerequisites for Windows:
Python 2.7.2 (http://www.python.org/ftp/python/2.7.2/python-2.7.2.msi)
pyserial 2.5 (http://pypi.python.org/packages/any/…-2.5.win32.exe)
Usage:
Install Python + pyserial (see “Prerequisites for Windows”). Install drivers. Connect Teensy
to your PC. Flash Teensy with “teensydefaultNORway.hex” and reset it after completion. Start
Windows’ “Device Manager”, expand the “Ports (COM & LPT)” node, you should see something like
“USB Serial (Communication Class, Abstract Control Model) (COM4)”. This tells you that “COM4″
(or whatever shows up) is the COM port used by Teensy.
At the command prompt enter “NORway.py” to display help.
Procedure to dump your flash:
- PS3 is turned off
- At the command prompt enter:
NORway.py <your com port>
- Turn on your PS3, it shouldn’t boot
- At the command prompt enter:
NORway.py <your com port> dump flash.bin
- When dumping is finished enter:
NORway.py <your com port> release
- Power off your PS3 (disconnect Teensy if PS3 doesn’t boot when restarted)
Dumping takes about 3 minutes. A file “flash.bin” with a size of exactly 16 MB (16.777.216 bytes)
has been created in your current directory.
Flashing is rather slow. Writing a complete flash with the “write” command takes about 2 hours.
Might be improved in future versions…
IMPORTANT:
Before you flash your PS3 with anything new, make sure that the content of your dump is correct
(e.g. compare ros0/ros1 area of your dump against “CORE_OS_PACKAGE.bin” from an actual PS3UPDAT.PUP
of your current firmware). And keep your original dump in a safe place. You might need it.
It’s tested on Win7 x86, but should also work just fine on any x86 Windows >=XP.
Basically it should also work on Linux, but I didn’t test. If you’re running Linux, you
probably know what to do. ;-) Serial drivers are not required for Linux.
Unfortunately I couldn’t manage to make it work on any x64 version of Windows, because of
the Python pyserial module.
Thanks to “marcan” for the original implementation.

PS: I’ve already managed to downgrade my OFW 3.61 to CFW 3.55. There’re minor things to rule out, but expect a downgrade tutorial coming soon..
PPS: Thanks to defyboy for the original idea of using a Teensy for flashing!
