    Downgrade to 3.55 CFW
    Upgrade to 3.60+ OFW
    that would be a nightmare lol

    Then again, nothing is 'unhackable' as it's only a matter of time. Sony's every attempt to secure the console has so far been flattened by Devs & hackers alike.

    Same with the Xbox - It's been quite some time since there's been any serious activity, only DVD FW which most the pirates have jumped straight on to cash in. I'm actually glad the JTAG/Rebooter Glitch has been found as now BOTH consoles can be used once again for homebrew.

    Sony might have the upper hand, but we soon catch up

    sorry for bumping this topic! hopefully there's someone that can confirm model CECH2504B datacode 1A ca be downgraded. it came with 3.56 out of the box MinVerChk shows me minimum firmware = 3.50 >>

    have checked the matter with E3 team, and they are not sure, its RARE model

    ps3 wiki shows it can downgrade, is there any way of checking the MELTR after installing the E3flasher and backing up the NAND Bios like in the first post?!

    thx for any help on this!

    From what I understand you can't below what the ps3 came with. So if it came with 3.56 that is the lowest that you can go.

    Thumbs Up


    that sucks, the thing is, if you check ps3 dev wiki it could work.

    New PS3 METLDR Revision in CECH-2504 May Block Downgrading-2505-1a-jpg

    Actual praxis: 3.55/3.56

    is MinVerChk no full-proof if it says Min Firmware: 3.50 can be installed? even though 3.56 was loaded.

    is there a possibilty. the shop returns the older ps3's, updated the firmware 3.56 at the time, put a new STICKER on the bottom with new Datacode. put the ps3 in its original box in another box and sell it as virtua tennis bundle they even give another controller and a platinum game for free i think they want rid of it.

    it looks though that the PS3 letters on the topcover are smaller then previous CECH2504B i can recall,not sure that the PS3 letters where bigger.

    should i try or leave it alone, i know its my responsibility!!

    if i try anyway hehe, is there a way to unbrick the system(with the NAND backup) if it fails at the downgrade?

    ps: i can get another FAT PS3 CECHL04 80GB for 180€, its a good system (16mb NAND) 180 is a bit much or good price?

    thx in advance!
