So I had this problem last night, and the guy at the Verizon Store helped me fix the boot loop that my DNA was stuck in, but now it's doing the same thing and it won't let me do what he did.
Basically a text box popped up saying that my phone was powering off in 'x' seconds. Before I could try to stop it, it went into a boot loop, as it did just 24 hours ago. I tried holding the power and volume down button, and it brought me into the bios, just like the guy at Verizon showed me, however once I'm in the menu, my volume and power buttons cease to function, and after a few seconds, it goes right back into the boot loop.
Also, my orange charging indicator light no longer illuminates when the phone is plugged into the charger, nor when it is placed on the wireless charging pad I have. Currently I'm considering letting the battery die and then charge the phone up and reboot it that way, but I don't want to let the phone die, only to find out that it won't charge either, and have essentially a dead phone.
Any ideas besides a new phone? I can't even select the factory reset option, so that's out of the question.
