Hi @TECH_GEEK10 -

I’m with @ScruffR on this one.

I think there are very few people, if any, that have managed to stuff up Photons to the extend I have and running Particle Doctor via CLI almost in all cases (but one where the Photon was physically damaged due to a short) resolved the problem. Providing you can get into DFU mode of course.

If you can enter Safe Mode you can also try Particle Update via CLI, but from what you posted it seems you cannot get into Safe Mode?

Best of luck!!  
Friedl.
