    “The Official firmware files provided here contain an anti downgrade mechanism.
    This can be bypassed by simply changing the name of the update file to that of a higher version number currently installed.
    To download a modified Firmware file, check the Downgrading box and then click the desired Download buttons.
    A file starting with 90.**.5 will be downloaded, where ** is a random number to avoid collisions in your downloads folder.
    We recommend once you’ve downgraded, to delete these files as to avoid future confusion!”

  2. I just tested the firmware 33.39.10, and the signal and penetrations seem weaker. Is there a way to make a rollback?
