Either way, "test" or demo device, we can't help. That phone is not for public use and your only solution is to return it to where it was legitimately bought so they can replace with a real, working unit.
As it's not the standard software, any rooting or flashing guides have the potential to brick the device, rendering it useless.
Your only way forward is to take it back to where it was purchased.
