I have jtp-001 slim 4.11 ps3 nor chip is 05 spansion.
teensy no vreg, 5v bridged (successfully downgraded my other ps3slim with it)
soldered to mobo (soldered twice and checked my connection twice)
used this testpoints from jsd-001
http://www.ps3devwiki.com/wiki/File:...testpoints.png

I got
Nor chip manufacturer: unknown <0x11>
Nor chip type: unknown <0x5e1111>
trying to dump.

What to do to resolve this?

edit: NVM solved it by using voltage regulator. Downgraded from 4.11 to rogero.

@liranantebi :
Just one question. Does NANDway v0.1 Beta already support verify after dumping/flashing or not?

I want to make some speed tests and comparing them with ProgSkeet 1.2 (I know that it's just a Beta software and doesn't support the differential flashing, but I'm curious), thank you for your support.

P.S.: as always, I'll work with desoldered nands from the mobo and install them in a zif socket.

Yes. It supports verify after write. Currently this is the default behavior on write. later I will enable either vwrite and write - which will let you choose what you want.
The verification is done per each block - meaning - erase->write->check per each NAND block.

I'm going to update very soon with differential write (work in progress).

Either way you work with the NANDs - make sure you have good grounding of the host (PC) and target(mobo/NAND chip).

Ok, thank you for your answer.

When I have time to test it, I'll let you know.

OK, so after hour and hours... And more hours of looking at post after post of information. I have to post a question.
Here is where I am at, ordered progskeet 1.2 (didn't do my research... Silly me) Found out that... Well it is basically useless.
I have a dual nand system. Looking at using teensy to read/write.
My questions
1) I see teensy doesn't supply enough power, can the system power the nands while teensy reads/writes to them (without causing errors obviously )
2) If not can the progskeet be used to power them (while on mobo) while teensy reads/writes.
3) Where is nandway? Looked on git hub, got a 404.

Sorry but after about 4 hours of looking around My head hurts too much to continue. (7am and haven't gone to bed yet)

If anyone can help me on my journey on flashing my nands please do.

Thanks ^_^

Tr1ckst3r,

you can use use Teensy to read the NANDs. The project is located at github.com /Effleurage/NORway-and-NANDway.
The NANDs on the mobo can't be powered from the 3.3v regulator. The current demand is too high (the mobo demands 1.8A and Teensy powered from USB can supply only 500mA).
The NANDs on the mobo can be powered from external source (like from the progskeet or from ATX power supply). Make sure that all grounds are firm and connected together - this will improve the reading dramatically.
With the NANDs on the motherboard you can discard WP# and RYBY# (no wiring required).
I've added support to Differential write - so once you have a good read and patch it using flow rebuilder - you can try it out and save yourself a lot of time.
Teensy can be still be driven from the 3.3v regulator (but not directly from the USB 5v). Just again - make sure that the usb ground is firmly connected to the ps3 mobo ground.
make sure you have no shorts and that each wire is connected and have no resistance (test it with a multimeter)

I hope it helps. good luck!

but you are liranantebi !?

and the link at github don't work...

So teensy needs a power supply as well? Or do I bridge teensy's 3.3v section
Sorry little noobish in this ^_^

(Also, I take it you can't supply the nands power from the ps3? IE have the ps3 running while reading/patching nands?)

Also I asked for anyone to help me. Thank you for helping me

Tr1ckst3r:
Re: So teensy needs a power supply as well? Or do I bridge teensy's 3.3v section.
I will share from my own experience..
google "Converting To 3.3 Volts". you will find the pjrc site explaining how to drive teensy from the 3.3v regulator.
from their site:
"Teensy 2.0 and Teensy++ have a place to solder a 3.3 volt regulator to convert the Teensy to run at 3.3 volts."
So you need to solder the 3.3v regulator, cut the 5v pad and bridge the 3.3v.
than you don't connect any +3.3 from the motherboard or the external power supply to the teensy +5v pin.


Re: (Also, I take it you can't supply the nands power from the ps3? IE have the ps3 running while reading/patching nands?)
I'm testing it right now. there is a special pin for TRI on the NAND motherboards. (still without success.)

Ahhhhh oK thanks.

All I have to do now is get one! Thanks for your help. Also could you provide a mirror for the nandway? It is no longer on github.
