Hello, I bought a 4g mini while on holiday in the UK just 3 days ago. It was working fine but suddenly stopped working. All the blue lights flash together on and off periodically. I've tried to reset by holding both the power button in for 10+ seconds and pushing the factory reset button under the battery cover for 5+ seconds with a pin. No change. I've noticed when I disconnected it from the mains power supply there are no lights at all indicating no power but its been charging for hours and should have a full battery.
