I tried updating today. First with the stock firmware and then the Rockbox firmware. When I tried to update the firmware I got an error message "Firmware update file not found"
I also looked at the music browser. There are no files found in the TF card or OTG device (not sure what this is).
I installed a card from Kingston, 8G before I started. I don't know how to switch between them, or why the player isn't reading.
Thanks,
Joe
