Ringtones won't work apart from marimba.. Please help!

[Babydoll24]

I recently installed iFile and tried to rename a ringtone with an mp3 file just to see if it worked.. I changed it back after to the original file name but now none of my ringtones will play at all ( they play in iFile just not in settings) and I'm left with just marimba. I really don't know what I've done wrong and any help would be much appreciated... Thanks x

This is irreversible, you will need to restore your iPhone ;(
