supercard DSONE EOS firmware

Hi can somebody please help I don't seem to be able to update my supercard DSONE to use the new firmware am putting all the correct files onto the microsd but when i put it into the DS I just get a blank screen

Extract it using a program like WinRAR. Inside will be a folder called ''en'' '. Open the folder. Copy the files inside it to the root of your microSD card. Finished.If it doesn't work , pleast try to format it.

I did all that including reformatting the sd card evan tried a different card but still no luck
