I bought an LG Volt from Best Buy around mid-August and I've never had any trouble with it until today. I was using Dolphin Browser on data with about 9% battery and it froze for a while and then the screen shut off and now my phone won't turn on. I flashed the v3 ROM from the all things root forum that had the pre-root and everything. I also installed xposed. There was no indication that it was going to shut down. I've had the phone plugged into power for about an hour but there's no lights like when you usually charge it. I get no response when hold any of the buttons or when I plug it in to my computer other than "USB not recognized". Any help in rescuing my beloved phone would be much appreciated. Thank you
