When I try to update the firmware for my HW-N400 soundbar using USB, the soundbar displays the following message: NO DAT. The ROM file, HMS-N400WWB-1000.3.ROM, is on the root directory of the usb drive and not in a folder. The reason I want to update the firmware is because the soundbar suffers from audio dropping out on occasion. If there is another way to correct this problem I would love to know about it. Thanks.
it is Fat 32 and 32 gb
