Hello guys, i need to update the firmware (mine is 1.00 version) of my MATSHITA BD-MLT UJ240AFW

I tried several of them, but no one works:

Firmware Search - Firmware HQ

...can someone help me?
My PC is an ASUS N75SL.


-PS-

...alternatively i have also tried to update the drivers, but i have found nothing.
I look forward, thanks...
