Help, Hongmi Won't Boot

Oct 10, 2013
I was just sitting around today when my Hongmi made that "reboot sound" from across the room. I ignored it because it's spontaneously rebooted a few times before. When I looked at my phone later, and it was still sitting at the "MI" booting screen. It never finishes. It takes a very long time to go from the black and white small MI logo to the red large MI logo. I have tried many boots, with SIM card, without, with SDcard, without, etc.

I tried booting into recovery by holding up+power and after many minutes, it boots up to a screen that says "Factory Mode" but goes no further. Anyone know what the problem is? It was working fine yesterday.
