    Check out your Slim model number:
    CECH-20xx(OK To Downgrade) NOR = Teensy++ 2.0 / Progskeet / E3 Flasher

    CECH-21xx (OK To Downgrade) NOR = Teensy++ 2.0 / Progskeet / E3 Flasher

    CECH-25xxA or B (with date code [0C] [0D] [1A] are known to be ok) NOR = Teensy++ 2.0 / Progskeet / E3 Flasher
    ALL THE REST(DOUBLE CHECK THIS with MinVerChk from HERE AS SOME CANNOT BE DOWNGRADED)

    CECH-30xx (CANNOT Downgrade)

    CECH-40XX (CANNOT Downgrade)

    This information was taken from HERE & HERE & HERE

    This thread has all the information you need to do it

    Just make it clear:
    CECH-25xxA or B (with date code [0C] [0D] [1A] are known to be ok) NOR = Teensy++ 2.0 / Progskeet / E3 Flasher
    ALL THE REST(DOUBLE CHECK THIS with MinVerChk from HERE AS SOME CANNOT BE DOWNGRADED)

    [1A] - Not always can be downgraded but can be hackable. If its downgradable you can install OFW 3.55, if can't downgrade you can install CFW higher than 4.21.

    [1B] - Sometimes hackable.
