My nexus 4 wont charge or turn on, and had a blinking red light known as the "red light of death" when i plugged it in or tried to use any of the buttons. Ive tried holding on to the power and bolume down buttons, the power and volume up buttons, and the power button alone. Ive made various google searches and nothing theyve recomended has helped. Now, the red light is completely gone but the phone still wont turn on or charge. What do i do?!
