First let me say this is for NOR PS3 's only... 1st gen fats cant do this. check your compatibility before trying. There is another solution for nand systems but I will get to that later.
Click here for compatibility check
Also this is not like regular ps3 hacks , this process is similar to a jtag on the xbox. There is soldering involved.
If you are freaking out looking at this no worries ... solderless clip on available now... see below
how it looks installed....

PS3 Downgrading Tutorial w/ ProgSkeet and Teensy++ 2.0
Submitted by greg; Wed, 08/17/2011

And here it is: The tutorial, courtesy of dospiedra, for downgrading PS3 OFW 3.70 to CFW 3.55. Now I wouldn't attempt this if a) you're scared, b) you suck at soldering, or c) you have absolutely no tech. skills whatsoever. Otherwise, if you know what's up and have a ProgSkeet or Teensy++ 2.0, then solder up and get your downgrade on.

Translation provided by Mximposter:

    Hello everyone, I finally got it, we have a downgrader for SLIM consoles, this time a bit different that I did with PHAT models, I made it for both flashers, ProgSkeet and Teensy++!

    First You Need:

        * PHAT or SLIM console with NOR updated to 3.70 (*DO NOT TRY WITH ANOTHER VERSION*)
        * Solution to write and read the NOR of the console (flasher ProgSkeet or Teensy++)
        * HXD program (a good-hex-editing-program, that you like and know how to use!)
        * FlowRebuilder v.4.1.3.2
        * A cold beer (this is important)
        * http://pastebin.com/yuvJ5Leh Downgrade.bin

    First we dump our NOR with a flasher, the file size must be “16,777,216 bytes” no byte more or a byte less, take several to be absolutely sure of what you doing.

    Get the dump “example jakemcallister.bin” and we have to get it into FlowRebuilder to make it readable, the option is called bytereverse dump and extract.

    Do it and you will have a file but the extension will be bin.REV open it with the HXD and take out our personal data of the console EID, BOOTLOADER, CSID and METLDR.

    Now we need to put even more data!

    We get it with the following way:

    In this case we get our METLDR in our prepatched image for downgrade attached in this tutorial inside the folder where FlowRebuilder had placed our.rev also has created another folder called “nameofthedump.EXT” in there are our personal files of our console and we need to get some to place em inside the pre-patched image that I attached.

    Open the HXD and open downgrade.bin and the metldr file that is inside the folder asecure_loader, we pick the tab on the HXD metldr and copy all the HEX content to get in inside the downgrade.bin.

    Press control + g and write “810″ thats the position of the metldr right click on the first line of the position 810.

    And choose “paste writing” and in the same way we introduce the other ones

    The files to get in are:

    - :METLDR: offset “810″ size “E960"
    - BOOTLOADER_0 offset “FC0000″ size “40000"
    - EID: offset “2F000″ size “10000"
    - CISD: offset “3F000″ size “800"

    Then we take the downgrade.bin with the saved changes and we get in FlowRebuilder with the option bytereverse dump and extract.

    This time the program will give us a error, but is a normal error, in fact is okay and will give us a file called downgrade.bin.REV.

    And thats the file you have to use to “flash” the console with now.

    If all went well at writing, turn on the console and you will see in the screen push the PS button, BUT DON'T DO ANYTHING ELSE, turn off the console and put it in factory service mode, once done we need to put the correct file system for 3.55 lv2diag of jaicrab without reader and a special cfw:

    lv2diag: http://www.logic-sunrise.com/telecha...r-jaicrab.html
    cfw: http://pastebin.com/03MFDLGV

    Turn on the console with the usbstick with these two files in the right usb port (in the last) of the console and it will shut down after 10 / 15 minutes, turn on the console without any usb connected to verify that you did it correctly it will take you to xmb.

    If all went well turn off the console and put your lv2diag FILE2 from this pack: http://pastebin.com/gGETcxMR

    The console will turn on for 20 seconds will turn off itself and CONGRATULATIONS your console will be 100% functional and running 100% the kmeaw CFW 3.55 now!

    Thanks to:

    * DiGiTaLAnGeL (Tester with progskeet)
    * Glevand & mfw builder team (cfw)
    * NDT (Assistant) is a very good person
    * JaiCraB (lv2diag without reader)
    * Robs1 (my guide with the nor flash)
    * EussNL (his great support in the wiki that I use every day PS3DEVWIKI.COM)
    * Defyboy (for creating ps3devwiki)
    * To the whole channel darkps3 from irc-hispano.org for their support and many hours of testing we have hit hard mother****ers!
    * DemonHades (because if you had not post on your website with the lie you said about me, I had not met DigitalAngel or uf6667 and these two helped me a lot)

    And finally to the people who asked me in private to have a donate paypal button, here it is.

    Greetings and from now on, I will resume my work with the DUAL NAND and that dump 3.6x that gives me so many problems. hehehe

    I have updated the position of METLDR that was earlier misplaced, the correct offset is "810" size ”e960″, please make note of this, it is VERY IMPORTANT!

Sorry if it came off the wrong way... I just wanted to collect all the information I can before I posted it. I wanted to be thorough so people understood what it takes to do this mod. This is huge news for people waiting to downgrade thier slims. BTW Fats even with nands are down gradable with the same tool just a lil different procedure. TUTE for fat w nand coming soon.
Also this is a universal unbricking tool.

There is now a clip on nand and a clip on nor flasher for the progskeet.
If you have an ol phat ps3 w nand you can use the 360clip nand solderless clip on. Nand also has option for clip on dual boot...
pic shows clip on dual boot nand and old progskeet. new progskeet doesnt need extra adapter. I own the new blue one ... highly recommend.

If you have a nor you can use the solderless clip on 360clip nor.
