If you added songs to the device in MSC mode, then switch to MTP mode, you will not be able to see the songs added in MSC mode and vice versa, though the space used on the player will still reflect their presence. Switching modes should make the files show up. For example, switching from MSC to MTP mode or vice versa.
For older players - e200v1, c200v1, c100, m200 - the files become hidden files if the modes are switched. An easy workaround is to edit the folder options to show hidden files.
STEP 1 - Edit the folder options of the computer to show the hidden files
Windows XP: 1. Double-click My Computer. 2. Under the Tools menu, select Folder options, then click the View tab. 3. Under Hidden files and folders option, select Show hidden files and folders. 4. Uncheck the Hide protected operating system files (Recommended) check box. 5. Click Apply, then click OK.
Windows Vista: 1. Double-click Computer. 2. Click the Organize button on the upper left corner. 3. Click Folderand search options. 4. Click the View tab and select Show hidden files and folders. 5. Uncheck the Hide protected operating system files check box. 6. Click Apply, then click OK.

As you said your cellphone giving error of bluetooth operation faild i'll recommend you to Turn it off then On . If this does not work then you are suggested to get you cellphone software reistalled so that may fix other problem if there are any including the bluetooth error.
select show to all in blutooth setting to connect your bluetooth with other devices..if you are using ear piece (bluetooth) first add it in your devices connect it..and once it connected select hidden..so no other bluetooth device can interupt
