    I have a defective Prowise PW-55v02, it is stuck in standby.
    The main control board is a B.MSD309.33C 12365.
    (Similar boards/chipsets are used in Blaupunkt TVs, I've found that the firmware could be the culprit)
    So I'm looking for a firmware dump of U9 25Q32BS (SPI Flash).

    I took a dump of the existing flash but some bits flip from time to time.

    The panel is a T420HVN01.1

    Does anybody has a working dump/firmware file
