Hello All. Just yesterday I updated my blackberry 8830, after I started to add some new songs to my media card and started to try out the voice recorder. That night I tried to play some music on my phone but when I clicked play it said "Device Media Processor Is Busy"
and none of my music or ringers could place, so basically all my phone could do was vibrate. And I tried a battery pull which worked but then went back to the volumeless state. I noticed when there was no media card in my phone it worked.. This is what I did to solve this problem..
I took out my media card and I inserted it to the computer to notice when I opened the card, at the top of the list where all my music and pictures were it had the folder "BlackBerry
" which was not there before the update. When you open the blackberry folder you see music,ringtones, voice notes, etc. I copied all my pictures and pasted it in the picture folder and the music in the music folder, and when i was done copying and pasting i deleted all the stuff from where it was before. So all you would see is just the "blackberry" folder instead of seeing the blackberry folder and all your stuff. I inserted the media card back into my phone and everything now works perfectly fine.
HOPE THIS HELPS !
