Boron in Boot, Connecting, Reboot Loop

Hi,
I just wrote my first view programs in the web IDE to get start with my Boron 2G/3G and now it is stuck in some kind of loop. When I power it up the LED is white for a short time (start up) and then its blinking green (looking for internet). After about 12sec it restarts with white LED again and I hear the windows USB sound disconnecting and immediately reconnecting.
I tried the factory reset button combination. The combination works but it doesn’t change anything.
How do I resolve this?

I installed Workbench and CLI.
When I tried to monitor what is going on with
“particle serial monitor --follow -v”
the device magically recovered itself after a view more restarts.
Everything works again as expected, but I still have no idea what the actual problem was.
