I was just playing around on my phone and noticed there was an update so i went ahead and started it. When it was finished installing and on the screen with the green circle with a 1 in it, it quickly turned to a red triangle with an exclamation point in it. I have tried rebooting it several times and I have even factory reset it already a couple of times. I have also cleared the cache a few times as well. I have done everything you can do from the volume up and power button menu but every time it starts up again it goes right back to the red triangle. My phone is pretty much useless now. Does anyone know how to help me??
