But, it doesn't sound like you have tried a factory reset. For the Aura HD, this can be done by:
- Charge the battery for at least an hour.
- Force the device to power off by holding the power switch in the off position for about 20 seconds.
- Hold the light button down and turn the device on.
- Release the light button when the screen changes or the power LED stops flashing.
If it doesn't work, try again waiting a little longer at each step.
