hey, earlier today, i downloaded some songs on my computer and than transferred over the songs on to my phone. Just dragged and dropped in to the music folder. Than later that day i went to check up on the phone but it was off. So i pressed the power button to turn it back on. it got through the LG logo sign than it goes to the black screen of death. The computer didn't even recognize my phone anymore. It says that the USB device is malfunctioning and wont read it. Please help. This phone is not even rooted. I have to pull out the battery and pluged in the USB and nothing works. Any suggestions would be appreciated. Thank you .
