September 24, 2011 // 7:54 pm - This weekend the ProgSkeet Team has made available a video demonstrating the ProgSkeet PS3 Solderless and Dual NAND Kit Tools alongside details below.

To quote: We are happy to introduce you the SOLDERLESS KITS for our ProgSkeet device!

The main word is "BE FLEXIBLE" as ProgSkeet project will be the BEST TOOLKIT for the NAND and NOR flashing!!! We present today the NAND TOOL KITS, in few days we will be ready also with NOR TOOL KITS!!! Stay Tuned

1 - PROGSKEET is 100% PIN to PIN compatible with the SOCKET tool sold from this site

Just connect the ProgSkeet 32 pin special flat cable. (please note that this version don't support programming or reading with out the device is powered on. A new version will be released with the VCC pad to manage NANDS with a self power provided from PROGSKEET) and also us we will offer this socket in a package together with the 20 cm 32 PIN flat cable.

2 - ADAPTOR PCB: This pcb is an adaptor from 50PIN ZIF PROGSKEET CONNECTOR (necessary for the coming "NOR SOCKET" solderless tools) to 2 x 32 PIN ZIF connector. With this adaptor progskeet is able to manage 2 NANDS on the DEVICE and also extra 2x SECONDARY NANDS (for dual nand feature). The kit include the 50 pin flat cable from PROGSKEET to ADAPTOR PCB.

3 - NAND PCB: This "optional" pcb has a 1Gbit NAND flash on board. Progkseet is able to use it like a backup nand or switch this nand and use it instead the NAND on the board of the device. The feature called "DUAL NAND" allow to support different NANDs ONLINE and test firmwares in a easy fast way. The software will be ready soon to support this feature, user can also attach a switch to progskeet to allow a fast selection of the NANDs without using the PC tool.

Progskeet support max 2 x NAND PCB on each ADAPTOR PCB, the kit include a 32 PIN 3CM flat cable (from NAND PCB to NAND SOCKET)

You can see a FULL PROGSKEET KIT SAMPLE where is clear how is the complete kit with 2x NANDS PCB and 2x NANDS SOCKETS (on the picture miss one socket sorry J ) but I think the concept is clear.

The big advantage of PROGSKEET is that can work on ANY CONSOLE / DEVICE, is study to be MODULAR and so is MUCH CHEAPER then any other solution that is specific addressed to a device.

The nice special FLAT CABLES are also easy to be fitted inside the device without bit problems, and also the KIT is removable in few minutes and is not PERMANENT.


We will send tomorrow more infos and pictures regarding PROGSKEET V1.1 "CRYSTAL BLUE LIMITED EDITION" in production in these days and available in the market soon!

Nice news also about the PROGSKEET software, that now support new nice features.

ProgSkeet 1.2 Bitstream 2013-03-30 by uf6668 is attached below, which fixes NOR issues with the following changes:

The long awaited fix for Progskeet 1.2 is finally here, uf6667 confirms this should fix the write issues people were getting with 1.2.

Download: ProgSkeet_12_130330_1909.dat / ProgSkeet_12_130330_1909[1].dat (Mirror) / ProgSkeet_12_130401_1824.rar‎ / ProgSkeet_12_120402_1730.rar‎

  • Dual boot using a switch (led on = secondary nand/nor, led off = primary nand/nor).
  • Supports both solderless nand and nor together. This should fix the write issues people were getting with 1.2.

ProgSkeet 1.2/1.21 BITSTREAM_12_130401_1824 (via is the second progskeet v1.2 fix NOR bitstream.

ProgSkeet 1.2/1.21 BITSTREAM_12_120402_1730 (via is another updated bitstream, again to fix the NOR read / write issues on the 1.2 / 1.21 progskeet.

+ Added metastability to the DQ ports to filter out noise and glitches

+ Reduced timeout from 1.3ms down to 320ns per word

+ Added timeout for reads/writes (1ms), no more blocking
+ Fixed bug where it would read gpio from data pins rather than from gpio pins

+ Increased metastability of USB (should no longer disconnect)
+ Restored Samsung Q compatibility that was caused by dualboot pin allocation

servo386 It's very hard to do. If you are not not really good at soldering I wouldn't attempt it. A few guys here offer a downgrade service it may be your best bet to look into that.

In general, how difficult is to pull of one of these ProgSkeet mods? Specifically to one of the old CECH0A launch models? I am familiar with soldering but I'm not sure I would say I'm good at it. This for experienced circuit boarders? I've heard of people sucessfully hacking CECH0A's but I don't if they had to downgrade their FW's beforehand. Anyone have any experience with this particular circumstance?

Thank you for the info. I will go and try it.

You'll need to solder to the pins of the two NANDs. Here are the NAND pinouts for the V1.2.

The 3rd pic is for the older one but its bigger so you can see what each pin is.

hello all.

I'm new here so a noob. Well I have a PS3 fat with cechg04 sem-001 motherboard. I got along a PROGSKEET V1.2 and now I want the ps3 downgrade. But I do not find this motherboard diagram of where I need to solder the wires. Could someone help me with this I've been looking for 3 days.

Thanks already

this is my link and dump both original and patched one. i byte reverse the dump and use e3 nor checker to check the dump. yes flashing the original one give me yold again. i use the last winskeet version.

How did you check and see if the nor dump is good? Post up the nor dump and I will take a look at it. Post it to a file sharing site. Thanks

Also what happens if you write your nor dump back to it without patching it.

Hello i have tried to downgrade a ps3 slim cech2004a with nor samsung k8q2815uqb-pi4b. i use the clip and turn on the ps3 for read option. i have made the cfi dump and it's good the dump of nor and it's good too, so i have made the patch for rewrite the nor... flash it (using winskeet and the write option is: single word and static timing).

after finish and verify the file i make a new dump of the nor, and it was identical to the one i have flash.

turn on the ps3 and boom ylod... Any idea? thx
