Need help downgrading COK-002

[sarkat]

OK guys i switched to Progskeet (white board ) and here is the results :

installed progskeet drivers and infectus and used infectus to update bitstreams and used ProgSkeet_Retail_SL_NAND111126.

and now on winskeet 4000 tested for shortcuts none found .but when i click on nand1 and click auto it says uknown i have tried and double checked my solder points and used different 3.3v but still the same

what cause this problem ?

Soem tips posted by @euss on ps3hax long time ago:

- use clamps, the pressure of fingers is unstable and will lead to alot of stress and bad dumps
- basicly there are 3 ways to handle NAND with progskeet (choose one, do not mix):
... - NAND + PRogskeet powered by PSU from console itself, using 3.3V wire to progskeet and using R7 switch (commonly named method1 in ps3devwiki)
... - Progskeet powered by USB, NOT using 3.3V wire, but having R8 closed, while using PS3 PSU for powering NAND flash (commonly named method2 in ps3devwiki)
... - Progskeet powered by USB, having R8 closed, while using 3.3V + GND wire from PS3 board to ATX powersupply for powering NAND flash (this is explained on talk page of ps3devwiki)

Because you work with NAND, some other tips as well:
- old Winskeet seem to have least problems detecting NANDs (always try autodetect, because if that fails, dump will also fail).
- never use second channel of Progskeet, only use the first channel, that is around the USB connector (or if you are using Y-adaptor/subboard, use only the one numbered lowest).

Hope it help.
Also make sure that you read and fully understand all of this: Progskeet 1.0 / 1.1 - PS3 Developer wiki
Also read this: K9F1G08U0A-PIB0 - PS3 Developer wiki is not strictly needed but good to know.

Yeah I have read that on ps3hax site and also just to metion I am using offboard using tsop48.and I have double checked everyting and read many thread all over net to ps3wiki downgrade. And ima really out of idea.

Also read this: K9F1G08U0A-PIB0 - PS3 Developer wiki is not strictly needed but good to know.

I am using that schematic.but not sure why winskeet doesnot detect samsung chip.

Hope ypu have some othertips on your mind for winskeet not to detect samsung chip.

I have no idea, maybe clean pins with alcohol (if not help try clean downgrader with alcohol, lol). Maybe [MENTION=29]Joonie[/MENTION] [MENTION=37]3absiso[/MENTION] or [MENTION=48]littlebalup[/MENTION] can help you. As i said before I'm not familiar with NAND, I only know that NAND consoles like dying after opening case (CECH-C user here ).

Lol yea already tried with alcohol maybe I will try with non alcoholic.lol

I am thinking maybe tsop48 is not working with the white progskeet but it's just the connection .
Also I will try direct solder to figure where is the problem
Anyway thanks for the tips I will update once o get some results

what progskeet version do u have

this one (white board)

just wanted to add some more info my pc detect progskeet in device manager .and i used Infectus to program ProgSkeet_Retail_SL_NAND111126.

Hello again i have tried with Progskeet 1.21 and update bitstream with infectus using ProgSkeet_12_130720_1716.dat

but i got this message while erasing

ACTEL_SLOG_UROW = FF FF FF FF FF FF FF FF FF FF FF FF FF FF 00 FF FF

Is ok, wait 30 second to one minute. And update will be finished.

Yea I tried that still not detected no matter what progskeet I use it doesnt work. I am switching to Teeny again at least it detect the nand.but I think my problem is with the re-scrumble process when I use Teensy some time it.modifies 46 blocks and with the same patchs using a different software it modifies 47 blocks not sure which one is correct.
