I was setting up my third Photon and ran into problems…
All went well until I did not get breathing cyan but ultimately "nearly steady/not blinking] green. Got back to blinking blue…tried again…but hung up with checking user ownership…
I did a factory reset and got to steady white. I understand next is use dfu-util to reflash.
I tried to reflash both 0.43 and 0.42 with Photon on DFU mode [blinking yellow].
In both cases part 1 loaded ok. Part 2 looked to be loading ok but ended with an error message:
dfu-util: Error during “download get_status”
Power off and Power back up just gets back to steady white.
