Was able to find my old Gigabeat S (30GB). I haven't done anything Rockbox related since I had my iPod 5G (30GB).
So, I installed Rockbox onto my device, but the dual-boot loader didn't seem to work. I can reboot the device and it goes straight into Rockbox. I want to go to the original FW too. Any ideas?
Also, does anyone know how I can start all the way from scratch (restoring the device)?
