    Help f/w 4.21

    i need HELP
    i bought a second hand ps3 it came with F/W 4.21 on it and was wanting to install OFW 3.55 using the USB but i cant get it to work .
    I have read many posts regarding downgrading but none of the FW i have tryed has worked & i keep getting error code (8002f828) WDF!!! (I looked for the code online and cant find it any where ).
    With the fw i have on my ps3 is there any way that i can downgrade or get the OFW 3.55 from a game/download if so which games/sites should i look for and where is the best place for FREE

    many thanks in advance

    You can download the minimum version check.pup here MinVerChk.rar
    You want to be able to install 3.55.

    To downgrade you need a nand/nor flasher like progskeet. ProgSkeet

    I haven't ever used one so I can't really help you with that sorry. Good luck

    He is right. The only way to downgrade is as I said above. You need a progskeet or teensy++.

    Since your minimum firmware is 1.97, I am guessing your model # is CECHH. Which is a nor model.

    You can also use e3 flasher, to downgrade. It comes with a solderless clip. So you wouldn't have to solder anything.

    You can check out my guide here.

    Like already said, there is no way to downgrade without a hardware flasher.

    It is fake. There is no jailbreak for 4.21. Your ps3 has to be on 3.55. Simple as that.
