New RAK 7200 unresponsive

I just received this today. As per the little note on the box, the battery was disconnected for shipping.

I have connected it (the plug only fits one way into the socket), and am attempting to charge, but there is no activity on any of the LEDs and the device seems totally unresponsive. The charger says 5.21V at 0.36A and has done for the last 3 hours.

Is there anything I can try? Is the battery faulty perhaps?

Thanks

Pat

Hello @patmolloy
Please connect it to your PC and check the activity, version of FW ant etc., according to this guide :

Thanks, it is alive. The board was not properly seated in the case so none of the LEDs were visible. Not convinced it is charging still, however. But I get see the device on a serial port now. Thanks.
