I’ve setup several Photons, but I’m having trouble today for some reason. After trying to set it up to our WiFi, the Photon quickly blinks cyan and then a very rapid (burst?) of red and then repeats the same pattern. Although I try to put it into setup mode to join it to WiFi (it seems to work part way), it always reverts to this pattern. I received 3 new Photons today and two of them are doing the very same thing. Advice? ---

This might help: [https://docs.particle.io/support/troubleshooting/common-issues/photon/#blinking-cyan](https://docs.particle.io/support/troubleshooting/common-issues/photon/#blinking-cyan) And so might this: [https://docs.particle.io/support/troubleshooting/key-management/photon/](https://docs.particle.io/support/troubleshooting/key-management/photon/) The issue you’re describing sounds like a keys issue (cyan with blinking orange). Give that a try and let us know if that worked for you. ---

This is getting frustrating…the first time for me with the Photon. All 3 Photons received today are doing the same thing. I have been working between two different Particle accounts. Could this be contributing to my problems in some fashion? ---

Seriously…3 “bad” Photons all arrived in the same package today? It really seems like something else is wrong. I believe I’ve gone through both of the steps outlined above, but without any success. I really don’t know if the device(s) should be considered “claimed” or not. They don’t show up under “particle list”, so that makes me think they were never successfully claimed. Regardless, none of the steps have made a difference. Some additional guidance would be greatly appreciated. You guys have spoiled me! ---

A video of the LED sequence might help diagnose the problem. Also double check that your photon has connectivity to the internet, specifically port 5683. ---

I had another Photon connected while all this is going on and I’ve never had an issue with all the other Photons I’ve setup here (or anywhere). I just recorded a 10 sec video, but it’s way too large. I’m going to try and downsize it and send it later. Thanks for chiming in! ---

Out of interest, could you tell me the version of system firmware on the problem photons? [Determining the version of system firmware on a Photon/P1](https://community.particle.io/t/determining-the-version-of-system-firmware-on-a-photon-p1/13324) In the initial factory run there was a key generation bug that would affect a small percentage of photons which was fixed in 0.4.8 - if this is that same bug, you certainly were unlucky to be bitten 3 times! 😧 But please bear with us - it’s not a permanent problem and we can get you up and running with these 3 units. ---

I already flashed 0.4.9 to one of the devices without benefit. What’s the easiest way to get a 10MB video to you? ---

With regard to logging out, I always use the default for ``` Would you like to revoke the current authentication token? (y/N) ``` Is that the smart thing to do (especially when switching between Particle accounts)? Truthfully, I don’t understand this question. ---

FWIW, I re-checked all 3 devices and they’re all running 0.4.9. I had re-flashed one of them yesterday thinking it might help, but with no benefit. Gosh, this is really getting frustrating. I have to believe it has something to do with my account. ---

Can you place the device in DFU mode and do `particle keys server` and see if it helps? There’s nothing to do with the account. All these are between the cloud and device so no account related stuff are involved. I guess the device has yet to be claimed, right? ---
