I just bought my phone last week, and it just arrived today. I bought it completely unlocked off of Amazon, intending to use straight talk as my carrier. But, while preforming some basic setup, the phone just shut off. It will not turn back on, and the charging light will not come on. I have tried other controllers, sockets, and even my computer as a source for power. Every once in a while, maybe after an hour of the battery being removed, I can get the phone to vibrate when I hold the power button, though nothing aside from that. I called LG, and they led me through some basic troubleshooting, then said my phone was not covered by the warranty and that they could not help me. Any suggestions?
