Just saw a post on elotrolado saying ntsc-j dumps are not valid for that tutorial. It seems lukin shared a pal dump of his own but there are no links anywhere.
I have CECHB and have read this post top to bottom. I have installed my infectus HB (Pain in the A**). I am ready to dump my nands.
My question is... Should I power the nands from the infectus 3.3v or power on the machine? Which method is the safest or best?
You must only power infectus with 5V. You must do that:
1. Turn on PS3 (standby)
2. Plug in Infectus to USB
3. Try to turn on PS3 two times.
4. Click on PS3 Double NAND flasher, you can dump/write
@btw: You have working console?
@NAND dumps: Please, If someone have NAND dump CECHG03/CECHH03, please publish It. Very big group of people needs it ;<
@yellowcapri: Hmm, really there is no need to power infectus.

There is confusion over powering nands.
From what i gather it is recomended to do a cold dump of the nands. PS3 powered off and external power supplied to the board 3-3.6v if powering nands directly. This is supposedly the most reliable way.
Infectus gets it's power from USB but has a provison for a 5v output on the PCB, some use this 5v to power the nands but it's not recomended due to problems people were having. (PS3 possibly drawing too much power from USB?!) Infectus should not need an extra power supply unless the one from your USB is unstable for some reason.
Flashing the nands should be done warm eg. PS3 powered up from it's own supply. Powering down via the switch on the back of the console is also recomended as people were having problems when powering down in the normal way causing corruption/errors on the nands.
Reading or writing from the NAND should never be done while the system is powered on. You should be supplying 3.3v externally.
You can also interface with the NAND controller chip via the NOR style testpoints on the bottomside if you wish to wire up a nor flasher. You do not need to worry about interleaving like this either.
if you try to power the nands whilst its still on the motherboard..good luck. there is a VERY heavy current draw in my cechc02 the draw was approximately 1.5 ~ 1.8 amps... which is VERY high(indicating other components are getting JUICE also)... also note that there is a potential voltage drop .. I supplied 3.3V from my variable DC power supply (no load) then connected it to nands but measured ~1.8V @ filter cap...
As for the 3.3V source from infectus v2 pad i measured approx 5V(it was no where near nand chip specifications)... and you can definitely NOT have enough juice(i.e. current) if infectus is powered through PC usb ports & the used to power nands.

For the record, powering the NAND's using only an external bench supply with NO additional power supplied to Infectus (V2), I can read the NAND's successfully.
I can confirm the current draw of 1.8A, which I believe to be the South Bridge (based on the heat of the thing).
When it comes to write, I can't see why it should be any different? Its not like you need more power to Infectus for a write operation.
So me personally, I dont see the need yet to power Infectus - just the NAND's.
On to the topic of rebuilding the NAND image - are there currrently any tools that allow you to enter in the location of bad blocks such that when the NANDs are rebuilt it automatically relocates the data around the bad block for you, in the correct manner such that it can be processed by the console when powered on?
No good splicing in data into areas of NAND that would contain bad blocks!
Thanks guys for clearing that up so read/write to the nands should always be done cold under external power.
Is 1.8A the current draw for the board alone or does anyone know if this rises with the card readers/wifi etc connected (playstation fully assembled). also are you guys using the points recomended by infectus next to the nand for powering?
I was gonna use a battery but guess that idea is out the window now
@yc in my case cechc02 - board alone, i powered @ point circled in purple from lukin thread - just give power at one cap. you can measure with m/meter to confirm all Vc legs have voltage.
battery should be ok...but use D cells or cells with large reserve & be quick.
3.3v right? Also, did you recover your ps3 from wanin brick?
