    The answer for it was posted already. You can downgrade it yourself or send it to someone to downgrade it for you. You have a NAND ps3 and you need to solder in a progskeet or use the clips on it. Thanks

    hi, you need a progskeet and solder about 50 wires 26 awg to read, patch, write nand. There is solderless clip solution but most of the time gives many bad blocks.

    If you dont have good soldering skills I could do it for you and if interested I also do nice light mods.

    PM me for more info and photos
