It's not unique to Armbian, I've done it myself with the pinebook when playing with screen brightness. The fix is to either login via serial/network and tweak the right sysfs path, or use a flashlight to light up the LCD panel enough to be able to use the screen again to turn the brightness up 
you just need to find a bright enough flashlight to be able to light the screen up enough... and yes, you basically put it right up to the screen, and shine it at an angle.
This was why a brightness script I published a while back has end limits on it so that it can't turn the backlight off!
