S1fwx

Sometimes you may need to manage the firmware associated with a particular portable player. By ignoring the fact that its extraction as a backup is really useful, you will be able to repair all types of MP3 and MP4 performing such a task.

S1fwx copies the firmware of any portable player to your own hard drive. To do this it uses the command console, so just run the file extract.bat after inserting the device into your computer to proceed with the extraction, which ends in a matter of seconds.

If the MP3 or MP4 has an error, it can be repaired using the file repair.bat.
