Nope... tried with this:
BKS25056-FGD177FLW-2-7-20. Result: LCD dead, player in mass storage mode only.
Just learned FGD177FLW has nothing to do with FPC-C177VHS...
So the only solution is to get the file that you mentioned, but i can't get it. Is there another place from i can download this? Because it seems to be the only compatible FW (at least the LCM driver)
Or, if you have access to that file... Would it be too much hassle if I ask you to upload to some other site, please? would be greatly appreciated...
