I got a broken one from a friend. It was missing charge port and pads. So I ran a usb cable to the trace points. Plugged it in. No less. Not turning on…getting 5 volts at the battery and getting voltages within range on the main board too. Gonna try the reset:
# Hold down the power button for 8 seconds, then let go.
# Press the power button once. The Fuel Gauge flashes white to red 3 times.
# Your device is now reset.
Should that fail I suppose I'll take the speakers and hook up another bluetooth speaker to make custom one.
