Good day, it happened such a situation dropped Olimpus mr100 (m: robe 100) and for this flew the hard disk.
I replaced it with a new one, filled in the original firmware, the device just started to glow and requires a connection to the PC, after connection it's just charging.
I spat and decided to fill Rockbox there, like everything started fine, it works, but when playing there is no sound. This situation is also on the second olipus, everything works but there is no sound.
What can be and methods of solution?
