So I had a couple apps opened. Just 3 total Chrome, Viper4android and Rocket Player and my phone froze. When the screen timed out it not won't let unlock it or show any kind of screen. Stays on black screen. The hardware taskbar buttons are all lit. No sound is made when its plugged into the charger either. Phone is ZTE Boost Max on 4.4 KitKat Rooted with Philz Recovery. I've tried booting into Philz like usual power + volume down but no luck.
