Can't get my Photon online

I can’t get my new Photon online - the app on the iPhone tells me that it is offline and that the setup isn’t complete.
When looking at the console, I get this:

  • No firmware is shown.
  • I can’t get it connected via DFU mode and USB whatever I try (I can get it flashing yellow without problem)

Can anybody help me?
