I already tried. The thing is that when I click "update firmware", the player just reboots and no changes.You may need to run the update again. As a last resort go back to the FW that last worked for you.
And the same reaction to other menu items, "Music", "Playlist" .....
The instructions say that need to install the original firmware, but I do not know where it can be taken.
