Unlocked bootloader on my phone no problem so decided to go on to rooting. Followed the xda video step by step, but using twrp as recovery instead of clockwork. Flashed twrp using fastboot. Instead of hitting reboot bootloader, accidentally hit power down. Device is now stuck on charge screen, even unplugged. Charging LED unlit, cannot power down/reboot. Anything I can do, or have I bricked the device?
