That's weird as I can't reproduce this with my device, but I'm still using a prototype.
Asking someone with a final device to give another try, but we can for sure try to change the minimal value as required. You can restore back the brightness if you have access to a terminal, by doing the following: sudo echo 10 > /sys/devices/platform/leds-mt65xx/leds/lcd-backlight/brightness Can you play with the values and find out what is the minimum you get that is still able to see visualize unity8? Our minimum is currently 5, so would be great if you could play with that bit and give us the feedback.

Even if you manage to reboot (you don't see the confirmation dialogue) you still have completly dark display which effectively "bricks" the phone (no battery removal) unless you are patient enought to blindly try and hit long time enough to increase the brigtness again.
