Unable to claim Photon

What is the output for one of the stubborn Photons when performing a particle setup?

Had some success today. Using Particle app on my cell, Particle CLI and Particle Build, all three Photons [Ted, Weather, & Redboard] are listed in my cell app, as devices in Particle Build, and by particle list. Ted will breathe cyan after startup, but drop back to breathing green after 20 seconds. It will not accept a flash from Particle Build. Particle identify gives Ted’s number, but particle device add results in failed to claim device, server said: Core isn’t online, 404. With Ted blinking blue, particle identify returns the protons number 2400…032. Particle device add 2400…032 will return successfully claimed device at times but will also return failed to claim device, server said: Core isn’t online, 404. Bottom line, Ted will not accept a code flash while breathing cyan or blinking blue. While blinking blue Particle setup moves through the questions to an endless “…obtaining device information.” Photon Weather seems healthy all round.

Could you try placing Red Ted in Safe mode, and see if you can flash it with a known good app then (Tinker/blink an LED)?

Thank you Moors
I put Red in safe mode, flashed it the RGB_LED code & it worked. Loaded tinker and turned on Particle in my cell. It was able to turn D7 on and off.
Switched to Ted with the same great results.
I believe that all three Photons are now functioning properly.
It has been a horribly frustrating three weeks but you and ScruffR pulled me through.
Thank you.
