    [Answered] Can't Downgrade new PS3 3.50 fw help?


    just brought my ps3 320 gig CECH-2502B, it came with 3.50 fw preinstalled. i get to the factory mode just fine via AVRKEY doogle
    but when i put in file 1 n mod 3.41 fw it results in constant blinkin of the green light on the ps3. even after an hr nothing happens so i'm forced to turn it off.

    it works fine when i try 3.50 fw and file 1.

    Ignore this if you have done these steps already: You need to put file 1 and the mod 3.41 firmware on a usb stick formatted to fat 32, in the right hand side usb port.

    You could also wait for KaKaRoTo to release his 3.55 downgrade solution in the near future.

    I suspect that CECH-25 with OFW3.50 preinstalled have minor changes in SYSCON eeprom, chipset configuration and/or BD-Firmware wich OFW3.41 is not aware of and unable to handle that - resulting in a panic or loop during boot. So you'll have to wait until this is found out and probably patched in a CFW.

    this ps3 yours have issues of downgrade because he come of factory with board in fw 3.5.

    Why on earth would you want to downgrade? Just install 3.55 Kmeaw. No need to risk a brick to downgrade a console that doesn't need it.

    If you are looking for OtherOS support then check out the Linux Dualboot CFW here:

    Please don't bump old threads and then start a new one about the same issue.
