I had my Home Assistant system running smoothly for quite a while. But last week my NSPanel stopped, the time display was frozen and no input was possible. The hardware buttons and also the relay switching from the dashboard worked. So I think something in the update process broke. In the MQTT logs I see this:
tele/tasmota_nspanel1/RESULT {"CustomRecv":"event,startup,53,eu"}
And no response is sent from my RasPi with its HomeAssistant installation. I have to admizt that I was a little bit confused when I set up the NSPanel with the eco-system, so I thought an update is always a good idea 
But now I’m stuck, the ESP-firmwar update stuck with a SAFEBOOT, maybe somebody can give me a hint how to correctly flash the lastes FW:
