Did you do anything special when flashing the BeatsAudioSGS20317.zip file? Because I found that the update script inside does not mount the system partition correctly. (Probably it's meant for SGS) I have to copy all files inside to the TestBeatsAudiob0317_.zip to flash successfully.
Besides, what player do you use? I use PowerAMP 2.0.5 build-488.
