Electron no mobile connection, Particle Doctor finished without error

Hello I unpacked an Electron an the 22th of december and checked it with the tinker app.
I could set an LED.

Today the electron does not connect to the cloud. After blinking green it blinks quick blue (listening mode).
I updated the firmware from 0.48 to 0.64.

After I checked https://docs.particle.io/support/troubleshooting/common-issues/electron/ sussessless, I run particle flash --usb tinker
and later “particle device doctor”. It finished without errors.
But the Electron still can not connect to the cloud and goes to listing mode.
In the Particle console I can see that the last handshake was on the 22th of december.

What can I do?

Blinking dark blue, listening mode, typically occurs if there is a problem with the SIM card or a loose connection to the Electron.

Unplug the USB power and battery from the Electron. If it’s installed in a breadboard, carefully remove it. Be sure to lift it from both sides; if you pull up from one side only you can bend the pins on the other side.

Flip the Electron over and remove the SIM card. Gently push down on the metal band to make sure it’s tight. In rare cases you may want to use a pin to lift up the tiny metal prongs on the Electron, but this is not typically necessary.

Put the SIM card back in. The metal contacts on the card face the Electron, and the cut corner goes on the inside. Make sure it’s pushed all the way in.

If that doesn’t resolve the problem, create a support ticket and we can continue troubleshooting.

Hello rickkas7,
Thanks for the answer. I tried what you said, but without sucess.
I am not sure about the listening mode.
When I look to this side https://docs.particle.io/guide/getting-started/modes/electron/ the color looks like cyan, but the blink frequency is faster, more like the frequency of the green (Looking for Internet). But my combination of frequency and color is not described there, so I thought it is listening mode. It changes from blinking green to blinking cyan and backwards.
When I try to set in in DFU Mode the LED is partly red on the side with the u-blox
module. at first cyan and read and than green and red.
Any suggestions?

That’s the expected colour as R+G = yellow which will follows after a short R+B = magenta (aka Safe Mode).

Are you seeing any other colours during cyan (B+G) blinking? (fast blinking indicates the cloud “negotiation” process which should be done in no time usually)
Can you post a video?

I have noticed that particle doctor sometimes doesn’t do the same thing as executing the respective steps manually, so try this

// in Listening Mode (blinking dark blue - B only)
particle identify 
// in DFU Mode
particle keys server
particle keys doctor <deviceID_from_identify>

If that does not work give this a try and post the output

Hello ScruffR,

So it is definaly not “Listing Mode” I compared it. Cloud negotiation process? Ok. It takes more than 10 s before it return to blinking green.
Are you seeing any other colours during cyan (B+G) blinking? No, there is only cyan.
Can you post a video? I tried to upload a video, but that is not supported, I can only upload pictures.
If you give me your Email, I will send them.

Have you opened a support ticket as suggested by Rick?

Now I opend a support ticket.

Hi tbartels71,
I’m running in your exactly same issue, after running the command “particle device doctor” without any errors.
It constantly blinking cyan , seems like a Particle cloud logging error.
Have you solved the issue in some way?

Hello LucaM,
Open a suport ticket
They will help you. In myx case the SIM-card does not work. They send me a new SIM Card.
