So I have been at this for a few hours now going through the guides and trying all the different methods of connecting, claiming, and finding the sparkcore.
I started by resetting to factory default tried the android spark core app on sprint lg g2 on my home network. it got the sparkcore to breath cyan but then said no cores found. I followed similar posts and nothing worked for me.
I tried connecting over usb on windows, install the driver; however, windows is not seeing the device in device manager. I tried just going through com port numbers hoping to find it and it still could not connect via putty.
I do not know how to try and resolve this. I have factory reset it multiple times, tried having it forget connecting/creds.
