use waterlilly file
 

I have updated my firmware different times. For new looks. I tried using the waterlilly program and I can not use the file to update my firmware to delete the other languages. The update program does not see the saved file.

theremper, You have to load the firmware directly to your player using Waterliliy. Connect your player and use the download button. Then if you want to save the firmware extract it from your player with s1fwx.
