I have Moto G with Bootloader unlocked and I have installed TWRP Recovery and I was using CM-12 Nightly Build.
The device was working fine but now The device just Blackouts after reboot and I am unable to access any control of device but when I press Power button for couple of seconds, it shows Reboot/power off/Airplane mode option.
I am able to hear caller ringtones and everything seems to be working fine except the screen is completely black.
