Hello ftanl
Yes there is, you can do it with s1clone v2.0. You can download it from here:
http://www.s1mp3.de/tools.s1clone.html
Support for a wider range of v9 devices.
I have the same player as you. If you achieve to create the firmware backup I would like you to send me the backup. Because my player is death now and I can't find the firmware.
Thanks and I hope it will help!!
