THIS FOR SURE HELP!!!!!!!Hi...I find the answer...Push and hold rec button and button for holding...And it will start..if your mp3 (a samsung yp-u3 mp3) says log val=0x10008018 or something, click and hold the record button and once it begins to record, press the back arrow/button (symbol in the top right corner). your mp3 should work (play music and such) now. to fix your mp3 and get rid of that log val message, you need to go to settings, then system, then format. format your mp3. unfortunately this will delete all your songs and files on the mp3, but the mp3 player should be fixed and the log val message wont appear anymore.
hope this helped..
