If there is corrupted data in your Mp3 player, please reformat your player your factory settings(it depends upon the manufacturer, mostly use the reverse side of the needle to press in the pinhole that is available somewhere in your player). This action deletes all the files in your player and all the settings are reset. Your player will be now like a new one. You can upload music again and use it as normal one. Thanks for choosing fix-ya!. Please rate my solution as helpful.
