NORway v0.7 - Teensy++ 2.0 NOR and Dual NAND flasher
WARNING: Use this software at your own risk. The author accepts no
responsibility for the consequences of your use of this software.
This project has been ported for the Teensy++ 2.0 from the original NOR flasher tool
("noralizer" by Hector Martin "marcan" <>) that was used to flash
AsbestOS onto the demo PS3 at 27C3, and for experimentation.

PS3 Teensy
Powering option 1 (voltage regulator, Teensy powered by USB):
Install the 3.3V voltage regulator available at! 5V trace has to be cut and 3V pads have to be shorted!
Please refer to
Powering option 2 (external power, Teensy powered by console):
Connect Teensy's VCC solder pad to PS3's 3.3V supply (see connection diagram). 5V trace has to be cut and
3V pads have to be shorted!
Please refer to
Connection diagrams for other boards can be found at:
Prerequisites for Windows:
Python 2.7.2 (
pyserial 2.5 (
Install Python + pyserial (see "Prerequisites for Windows"). Install drivers. Connect Teensy
directly to your PC (not an USB hub, might cause trouble). Flash Teensy with "\teensy\default\NORway.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.
* Flash Teensy with "\teensyNOR\default\NORway.hex"
At the command prompt enter "" to display help.
Procedure to dump your flash:
- PS3 is turned off
- At the command prompt enter: <your com port>
- Turn on your PS3, it shouldn't boot
- At the command prompt enter: <your com port> dump flash.bin
- When dumping is finished enter: <your com port> release
- Power off your PS3 (disconnect Teensy if PS3 doesn't boot when restarted)
Dumping takes about 1 minute. A file "flash.bin" with a size of exactly 16 MB (16.777.216 bytes)
has been created in your current directory.
Writing a complete flash using the "write" command takes about 4:30 minutes.
* Flash Teensy with "\teensyNAND\default\NANDway.hex"
At the command prompt enter "" to display help.
first make sure that you are able to read the NAND's info. do this by using
the info command.
get information: COMx NAND_ID info
dump: COMx NAND_ID dump filename
write: COMx NAND_ID write filename
NAND_ID is the id number of the NAND. it can be either 0 for NAND0 or 1 for
NAND1 on your motherboard.
Bad blocks (currently only PS3 is supported):
- Locate and print bad blocks in an input NAND dump file: badblocks Filename
- Remap the bad blocks of an input file to a new NAND given the new nand's dump (that is used to locate the bad blocks on the new NAND) remapbadblocks InputFile NewNand OutputFile
Before you flash your PS3 with anything new, make sure that the content of your dump is correct
(use the supplied tool "norpatch.exe", it's able to recognize any OFW core os).
And keep your original dump in a safe place. You might need it.

More information available at (thanks to eussNL and all contributors for maintaining this great wiki!):
It's tested on Win7 x86/x64, but should also work just fine on any other x86/x64 Windows >=XP. Basically
it should also work on Linux and OSX, but I didn't test. If you're running Linux/OSX, you probably know what to do. ;-)
Serial drivers are not required for Linux/OSX.
Thanks to "marcan" for the original implementation.
