danielassad , thanks for the tip on modifying the ADFUupdate file. i'm sure it'll be very helpful to others.
Back to your problem, your player would be using the v9.0.xx series firmwares here

As currently the firmware extractor S1fwx only supports upto v9.0.43, you might face a problem of locating a compatible firmware.
