I've downloaded and extracted the same EC update version as in your file, trimmed the 32-byte header from the EC update version N2IHT42W, here's the complete file (262,144 bytes or 256kB). Check your programmer and select a chip size of at least 256kB or greater and try, it should work.Attached Files
