I used CWM to install Beats Audio, after install and reboot I only get to the LG logo then to the moving LG logo. Then the screen goes black and the buttons dont light. Even though the screen is blank you can still see it has power. When I connect the USB I dont see it under computer, but I do hear the sounds on the computer like it connecting. But the LGMOBILE support sees the phone and reads the model and version.. What do I do to get to CMW or anything past the 2 first LG logos?
