Ok, I found a great link detailing which traces go to which pins courtesy of unbricker.com
unbricker tech page

Using the reference letters from the Undiluted Platinum mod-chip instructions, here is the correspondence to each.

Undiluted platinum mod chip instructions pic

Pin name: UP reference letter

IO7: A
IO5: B
IO4: C
IO6: D
IO3: E
IO0: F
IO1: G
IO2: H

CE: J/P (the one you cut)
W/En: K
R/B: L

Looking at the pins that are wired up, is it possible for the mod chip to actually re-write the data to the flash rom? I think if the PSP is bricked, then you must always use the flash rom from the mod chip. Does that make sense?

"UP" USB -> "UP" Flash

I'm bad at soldering and seeing the pictures i think you need a magnifier to do this, i'm not taking my chances with this one. I was wondering, what is the chance of bricking your psp? and how much time does it take to accomplish this, from an untouched psp to a fully assembled one again? For me it would be an option to buy a psp with the chip already installed :)

Hi Ookm i really really hope you can help
I have a massive favour to ask!?? I have a UN chip on the way but the only problem is my psp is 2.6 so i have no firmware to flash to the chip please could you send me a nand-dump.bin of either 1.0 or 1.5 firmware i would be extremely greatful i can apprecite the nature of this request and i realise my cheek in asking but i have nowhere else to turn! So if you see fit can you e-mail it to me at funkingwangsta@lycos.com or could you point me in the direction of the firmware i would be most greatful
P.s this may sound stupid but is there anyway i can flash a 1.5 eboot to a chip!??!

1. i haven't U.P.
so i don't know what format they use on FW backup

2. i can't send FW image to anyone
because it is illegal !!

Ookm: can you confirm this works?

I don't believe it does because that IC contains the RAM too...
If it does work, there are many possibilities to make much easier installation...

it's so funny
i don't think PSP will work without RAM :P
