My droid 4 bricked tonight when I was trying to fastboot 4.1.2 files. Now it won't turn on, won't light up, won't do a damn thing. I try plugging it in and the computer doesn't even recognize it, and rsd lite doesn't show it either. I'm stumped. I tried holding down all the buttons (both volume and power buttons). I tried plugging it into the wall, plugged it in to my computer with my factory cable (so it shouldn't be a battery issue). Whats my next play?
