deCONZ doesn't connect after ZSHARK use

I just got a ConBee II and I’m trying out the software. I’ll mainly be using it to sniff and to run OTA updates of devices.

First I ran deCONZ and played around with it. The I ran ZSHARK, it flashed the sniffing firmware and successfully captured some packets. Now I ran deCONZ again but it doesn’t seem to flash the coordinator firmware again. Clicking the Connect button simply does nothing.

You need to manually flash. Deconz doesn’t so that automatically.
