Hello, I have a CECHA01 BC 60 GB PS3 with a COK-001 motherboard with a NAND chip on the top and bottom side.
I bought a Progskeet 1.2 + NAND 48-pin 360-clip for downgrading my PS3 from 3.74 to 3.55.
I have filed the 360-clip to fit flush on the NAND but it will fall off with any movement.

So my question is what would be the best way to secure the 360-clip on the NAND if I wanted to use the PS3 to supply power to the NANDs? Would Electrical Tape work?

successful downgade complete using a teensy ++ on cechj03 with a dia-002 board.

was not a simple task but here is how i overcome some problems i had.

i started off the task by not using a voltage regulator and used the vcc from the ps3, this worked fine without any issues, created good dumps and all was fine until flashing the patched dump back, this would stop at 256k,
i moved to using the writeword command in norway.py however this give the same results.

i checked the vcc and at that point the voltage was floating about a bit and even at times dropping as low as 2.5v hence it was more than likely the nor that was failing not the flash as the vcc comes from the ps3 and the nor.

i then fitted a voltage regulator and tried the write command again once again came across the same problem still stopping at 256kb however the writeword command worked flawless and verified without problems too.
ive now fitted a switch to switch between the voltage regulator and the vcc, ive done this so i can leave the teensy++ connected and still within my ps3 but it can also be used as a factory service unit as well when the switch is set to the vcc power and if ever i need to flash i can swap back to the regulator meaning everything boots well and works without problems.

so here are my reccomendations

1 i used 30swg wire, worked without any problems on cables less than 15cm (had about 0.1 ohm resistance between the teensy and the trace on the ps3)
2 fit a voltage regulator to do the dumps as well, the voltage drop caused by the teensy++ cant be healthy for the nor chip and i was lucky i never bricked the thing.
3 dont remove the teensy++ from your ps3 for using it to get into factory service mode, just simply remove the voltage regulator and attach the vcc (no voltage drop was seen doing this so id go as far as saying its safe and better than removing the whole chip just to enter factory service mode)

Hello, great guide.

I have a fat ps3 nand. i read the guide, and am not sure what the development board is about.

to do the downgrade, am i getting this right?

i need:
progskeet 1.2
(with that board soldered to 3.3v to progskeet)
injectus
nand 360 clip
usb flash
AND development board (if so, which one would you recommend to a total noob like me?)

Thank you in advance, if positive i order the needed material and try it out and let you know. (is 1 clip used twice ok?)

Regards,
Shino

Development board means usb downgrader, like E3 Card reader.

I got a phat nor ps3, bought a e3 flasher online today. Just want to know if there are something in this guide in the e3 nor downgrade that is invalid? Cus i've seen a warning on a site that there have been some bricks. Just want to know if that part of the guide is safe
Edit: saw your note on the first page. I guess it's a good guide

my ps3 slim is at firmware3.60....is downgradable i already know that....i like to know if i must update to any particular firmware before downgrading or can i downgrade from the 3.60 straight away?

[Sarah1331]

You don't need to update pal downgrade will work on any fw version asking as you have a compatible console

[extek01]

please guys,,,how do i know which point is D15,D14,D13 etcs on a ps3 nor board?....i just open my ps3 slim to downgrade it hoping to see those points but was disappointed,,hw do i know which point to solder to..for example am soppose to solder p37 to D03 but i am unable to locate such points my ps3 board DYN-001...am using progskeet V1.2

For PS3 i'm not sure where to get the files and how to recreate a flash. That is why I asked, but considering what I read so far, I think it is not possible (yet?). For xbox you will also need CBA/CBB if you don't have your cpu key.
