Install ResetMusicAndVideosLibraries Configuration Profile The newest iOS Beta (7.6) says we need to install the ResetMusicAndVideosLibraries Configuration Profile to fix some bug.  How do I install that profile?  I tried dropping it into the Organizer window of XCode, but that didn't seem to do anything.
You can email ResetMusicAndVideosLibraries.mobileconfig on your iPhone and install it from the mail message.

After that:


Tap on Reset Library in Setting -> Music (it'll delete all your contents in Music and Video apps).

Restart your device.

Now you can reinsert your music and video using iTunes.
