The Blu Dash 5.0 Dual SIM D410 was released September 3 2013. Repairing this device is relatively complex and requires tools that have to be purchased.
You can't without erasing everything most likely. The best answer would be to research a way to erase the phone's data while it's plugged into your computer. After you erase there will be no passcode but there will be no data either.
