I removed some of the stock ringtones (from my ROM) that I didn't want from /system/media/audio/ringtones and added some new ones that I got from the xda forums via my SD card and RootExplorer.
When I open the Sound/Default Ringtone menus in settings, some of the old ringtones are listed and new ones are listed as well, none of them play. The only ones that do are the few that I left in /system/media/audio/ringtones and a few stored on my SD card.
How can I fix this issue so that my phone recognises that all files are in their proper directories?
