[Spark core] Common issues

:frowning: I was able to connect the Spark to my wifi access point and claim it only once (and only after I rebooted the AP itself). After that i’ve never been able to go past the green blinking.
I’ve tried to patch the CC3000 but i get the error message

Cannot open DFU device 0a5c:21e2
Error writing firmware…Cannot open DFU device 0a5c:21e2

My device is a Spark and is set in DFU mode connected to a USB 2.0 port. libusK driver installer via Zadig. I’m running Windows 10.
dfu-utl -l shows this
