It looks like there is no way to replace the firmware, there is a guide for the “Sansa” player, but nothing for the Clip Sport it seems. Also a few posts on this forum about the locked down firmware, didn’t see a solution besides sending it in somewhere to replace the firmware, maybe check those posts too (“BOP” in the title)…
Didn’t find anything on how to get it to play MP3s either, kind of sounds to me like this firmware should refuse to play them in any case, because that seems to be whole point of it ?
Good luck, have been in many similar situations spending countless hours trying to get some old device to work again, maybe sometimes it’s better just to ditch it.
