    Go to System Settting > System Information and make sure your firmware isn't 3.52 M33 already.

    You should update just like if you're on 1.50 except you must use the GAME150 directories.

    did you try to go straight to m33 3.52-4 or m33 3.52
    you have to go first to m33-352 and then to -4
    i upgraded from oe 3.40 to m33 3.52 and then to m33 3.52-4
    and all work`s well
