I'm trying to find the nor Tristate PIN on a DYN-001 board. Could someone explain what I have to look for with the multimeter? Or have already one found it on this board?
You need the datasheet for the chip that the board has.
Find which pin in tristate and use a multimeter to check for continuity between the pin and a test point
The tristate pin is actually called SB_DISABLE, Unless you are keen enough to lift and replace the southbridge BGA chip then this won't work. It basically disables the southbridge I/O pins and puts them into a state of high-impedance so it doesn't interfare with us reading the flash.

Just make sure you don't short any of the 3.3v power points.
gibata: http://ps3devwiki.com/index.php?title=Hardware_flashing does the pinout look like these? If not I would appreciate the pinout on the wiki when you are done.
Excellent work, Thank you. I have put the pics on the wiki. Did my method work for locating the SB_DISABLE pin? or do you have another method?

@yellowcapri or anyone else who knows.
Question. On the forums you posted a SEM-001 Test layout. It has all of the infectus test pins, and then extras. I have an infectus v2 coming. It looked like the guy who posted afterwards that wrote in all caps.
Anyway, I was wondering if you had any further proof that this worked because I am in desparate need of this solution. I have a unique brick working on flashing NAND consoles with Linux. I need a safe dump that would not require the two nands to be interleaved as it is done via the points already running through the Starship 2 chip creating one file. I would get a Teensy 2.0 ++ for this if needed.
Is this the case? Is this doable? If so, how would the power situation work with giving the nands juice? Does this method (if it works) work by turning on the PS3, letting it get to where it needs to go, then taking a read?
I will be eternally grateful to you if you could help me out here. I'm alone in a world with a one of a kind brick on a SEM-001. I have infectus v2 coming in the mail already, and this could save my butt as i'm skilled at soldering, but maybe not quite that skilled to solder 30 awg to nands.
Also the whole interleaving and combining with calculating bad blocks seems next to impossible without good software (which i'm not sure even exists.)
What I need is a DUMP from my nands, edit a couple of blocks. (I already know where I need to edit.) Garbage it out, then reflash.
This would be a godsend if this will auto split them via the test points to the two nands.
Please help me!
One lost soul.
Edit: I just ordered a Teensy 2.0 ++ with 3.3v regulator for this occasion.

Today I connected SB_DISABLE to ground on my bricked slim and entered the mode I quoted above. I got a new sequence of lights.

Has anyone been able to determine what this mode is used for?
No, I was able to reproduce this once but all lights were green. Have you figured out a constant method to reproduce this mode? What were the symptoms of your console?
