Sorry we couldn't find the cause of the failure. It's really weird, we've never had anything like this, it's not a software issue, maybe it's the voltage instability causing the MCU pointer error, but I'm not sure. You can try to factory reset the parameters, and if it doesn't work, you should get a refund.
Factory reset method: menu->set, and then long press the "Auto" button.
