    Default Is it possible to downgrade my PS3 without E3 Flasher or Progskeet?

    I have a 1st gen PS3, is the PS2 backwards compatible version.
    I purchased it from some dummy on Craigslist that discarded the whole blueray drive when he tried to replace with a new one...
    Lost the PCB that attaches to the ODD.

    Now I have a PS3 without a disk drive in it.
    I already have 2 other PS3s that are working just fine, but would like to flash this to CFW if possible, just to play with.
    I had read somewhere, I thought, that there is a way to downgrade now... depending on what the lowest possible FW is installable on the console.
    Of course, the lowest possible FW on this one is 1.00.

    Is the only way to do this with an E3 Flasher or Progskeet?
    If so, then this will just be a media server for the kids, because I refuse to drop a ton of money into this console.
    The most I would be willing to invest would be a new drive if it were downgradable. I have to downgrade so that I can marry a new board to this console.

    Any help would be appreciated.
    Thanks!

    What CFW do you want?
    Think about that before you make the step.

    Mainly want to drop to 3.55 long enough to remarry a bd drive. After that, I'm not sure I guess. I found a website called ps3hax that talks about being able to drop to 3.55 from 3.66 and up.

    There is no way to downgrade OFW to OFW without a flasher, you can only downgrade using software if you are already on CFW.

    That's why I come here. Usually everyone knows what they are talking about.

    What do you suppose these instructions mean though?

    "Instructions:

    STEP 1: Plug a USB stick into your computer
    STEP 2: Create a folder in the root of the USB stick called PS3
    STEP 3: Create a folder inside the PS3 folder called UPDATE
    STEP 4: Download PS3 PUP Updated
    STEP 5: Unzip PS3UPDAT.PUP
    STEP 6: Move PS3UPDAT.PUP to the directory UPDATE that you just created on the USB stick
    STEP 7: Plug the USB stick into your PS3
    STEP 8: Navigate to Settings Tab
    STEP 9: Choose System Update
    STEP 10: Choose Update via Storage Media
    STEP 11: It will say it found Version Downgrade
    STEP 12: Choose OK
    STEP 13: Accept Conditions and Install Update
    STEP 14: After less than a minute, your PS3 will update, beep 4 times then shut down.
    STEP 15: Power up your PS3 (You will have to do it on the console and not by the controller)
    STEP 16: Your PS3 is now on CFW !

    Work on All models slim and fat.
    100% tested works!"

    My statement is not completely true, when the first jailbreak dongles came out, you could downgrade from 3.55 to 3.41 or 3.15 using the dongles, with a special pup. There is no way to do it from any ofw above 3.55

    The instruction you have in the post above me is how you go about installing CFW

    So my understanding is that without a E3 I can in no way return my PS3 back to 3.55 OFW... But that with the method above that I can install 3.55 CFW. It's that correct? And if so, then can I remarry a bd drive at that point? Or must it be OFW?

    Lastly, if I can remarry a bd drive using CFW, am I able to return my ps3 back to current OFW?

    Mainly am wanting to make this PS3 usable again. Can't even use Netflix or Hulu where I am missing my bd drive... :-(

    Appreciate everyone's help so far. Thanks!

    No, the ONLY way to install a CFW is to be on OFW 3.55. Which as stated you CANT downgrade without E3 flasher. So your ONLY option is to get a flasher.
