This is a very peculiar behaviour. These status reports do bear some info, but whether or not they indicate some incompatibility is difficult for me to say as I don’t know of a comprehensive doc that lists good vs. bad combinations of firmware modules (@rickkas7?).
Maybe you could also provide the output of particle serial inspect (forgot serial before 
) with your device in Listening Mode.
Another thing you could/should try is flashing the bootloader for 0.8.0-rc.1 (and 0.7.0-rc.4+) which has to be done via particle flash --serial not --usb.
However, 0.8.0-rc.1 (and I guess rc.2 too) has an open issue reported by me about connection loss detection
