    Mushy409 Only the (355)patchcos.bin? i don't need the patchtrvk.bin?

    dayv i think he means the nand. because he is talking about 256mb.bin

    Is there a way to downgrade Nand Consoles from 4.00 to 3.55?

    But you say mushy409 speaks about Nor consoles, but he is speaking about 256mb Nand.

    Without the 2patchtrvk.bin???

    I've tried 1patchcos.bin / 2patchtrvk and 1patchcos355.bin / 2patchtrvk.bin but it doesn't work. I have done it how it was explained in the Tutorial but doesn´t work.

    Then i've tried only 1patchcos.bin and only 1patchcos355.bin but it doesn't work.

    Plz, anybody of you have an answer for me?

    Let me have a quick look thru your NAND dumps...

    Looks like your NAND dumps are ok, you should use 355patchcos.bin first - if that fails try applying the trvk patch. I haven't used the 3.41 patched COS yet. Are you sure you're patching from the right offset? C0020 - make sure the cursor is flashing at the beginning of that offset.

    In flowrebuilder when you de-interleave the modified 256Mb image, you need to select your original NAND0.bin & NAND1.bin - then select your modified 256Mb image. This creates your modified 128Mb flash images.

    You'll be left with NAND0.bin.new & NAND1.bin.new - flash these files back with Differential Flashing (no verify)

    When it's complete, dump BOTH NANDs again & compare them against your NAND0.bin.new & NAND1.bin.new - any differences = bad flash/bad connections to NAND.

    The reason I said downgrading 16Mb NOR consoles is the same for 4.00 as 3.7x, 3.6x etc is because this is true. I've downgraded BOTH NAND & NOR consoles on 4.00 firmware without problems. The 16Mb NOR console I did only required the first patch (3.55 COS) to 'black screen' the PS3 for FSM downgrading.

    I've tried it how you explained it (like i did before), and again only ylod. I have flashed back the original dumps (only for testing) and the ps3 is running.

    But this time i've tried this: When it's complete, dump BOTH NANDs again & compare them against your NAND0.bin.new & NAND1.bin.new - any differences = bad flash/bad connections to NAND.

    and the Nands are exactly the same (compared with HxD).

    I really don't know what more is to do.

    i don't know

    Can you upload your patched NAND image? I'll take a look and see if I can do anything...

    Just looking at your patched dump... I can't understand how your NAND image is interleaved, but mixed up every 0x200 in sections... I'm re-downloading your original dump, then I'll patch it for you and re-upload the new image

    Smile Badblock

    that means, his NAND DUMP had badblock. and i am really sure thats came from SAMSUNG UOB. it has more than 2bad blocks after interleaved. and most of badblocks are in Core_OS area. that's the problem come.


    Note :
    - Flowrebuilder only do ECC not remaping BADBLOCK.... so remap the downgrade patch base from core_os dump.
    - As long as BADBLOCK not store on Core_OS area, you are lucky to go

    regards

    Sorry for my bad english
