    i tried upgrading to both 3.72 M33 and 3.72 HX and when i start the update it says i need 3.52 M33-3 or higher and then it exits. I go to my system settings and it says 3.52 M33-4 so i dont see why it wont update.

    plz help
    thanks

    best would be to create pandora's battery and universal unbricker v3 memory stick. using them will give you the option of official 3.71 or 3.71 m33-2 with no hassles.

    go HERE for instructions.

    so i starting installing pandora's battery and when i get up to this step: Turn off the PSP and take out the Battery then re-insert the Battery back in the PSP and the Universal Unbricker Menu should come up. press X to install 3.71 M33 to the PSP.

    the psp light goes on after i put the battery in but the screen stays blank
