Here are the instructions on how to extract the firmware of your MP3/MP4 player using the S1fwx tool.

Note: This is NOT fully supported for 9.x.x firmwares as it is not able to extract your firmware fully. Please make sure your player's firmware version is 3.x.x for this to work properly.

The S1fwx tool can be downloaded here. This will only work for ACTIONS chipset players (ones that play .AMV video files).

1. Connect the player to your computer with the USB cable. Make sure your computer detects the player and a drive letter is allocated to your player from My Computer.

NOTE: If you do not run the "repair" on the your "dump.bin" file after extracting it using the S1fwx tool, then you will get ERRORS when trying to upload it to your player.

14. Go back to the folder that the S1fwx program is stored and you will now see another new file, "dump.bi$". The "dump.bi$" file was the original "dump.bin" file from step #12. The NEW "dump.bin" file is now repaired and ready to be modified and uploaded back into your player.

15. This new dump.bin is the backup of the firmware for your player, so keep it in a safe place. The dump.bi$ is not needed.
