If you have the .ecc file, you should be able to just plug in the USB drive, open it and copy the file into the 1st window.
If you're having problems with the extraction process, what extension is on the file before extraction? Even if it's an .exe file it may be a self-extracting zip file that can be opened with an app like Stuffit Expander.
I have an update for my tv. The instructions say: Extract the *.ecc file and load it to the root directory of a USB removable memory drive. Does anyone know how to do this on a mac or where to find the info? Thanks in advance.
