    Slim PS3 4.11 to 3.55 Downgrade help?

    Hi Folks, I hope your day shall be nice. I was just wondering If I can Downgrade my Ps3 Slim from 4.11 to 3.55 Without Any Additional Hardware, And How?

    My Ps3 Firmware Version : 4.11.
    My Ps3 Model Number : Cech 3004-A.

    And If there's any way to jailbreak or downgrade my PS3. Please tell me. Thank You.

    Additional Hardware = e3 Flasher or something like it.

    The only way to downgrade if you have updated past 3.55 is with a nor flasher which reprograms the chip with 3.55 coreOS however you have a new unjailbreakable console which is not downgradable and is unhackable for now. you need a CECH-2503B or below.
