Trouble getting a new electron up: LED flashing cyan

Yes. The battery is fully charged. The red charging indicator LED turns off within a couple of minutes of connecting the USB cable.

[EDIT] I am occasionally (1 out of 20 times) getting this sequence: Flashing green-> Flashing cyan-> Couple of orange blinks -> Flashing cyan. I will now try to find and flash the same code that an out of the box electron comes with, Not that I have flashed it till now, but I am clueless and think that there might be some problem with the program currently on the device. Kindly provide any other suggestions meanwhile.

[EDIT2] I reinstalled tinker on my electron with

particle update
particle flash --usb tinker

Still the same old story.

[EDIT 3] Tried the following with no change in result:

particle keys server

I am guessing that the people at [SOLVED] Electron high frequency flashing in cyan - #51 by ScruffR are facing the same issue. Maybe the problem is actually SIM related. C'mon particle. Do something.

[EDIT 4] As suggested in above link, I used keys doctor and all the steps completed successfully. I also tried everything with another electron that I have. No change in results. This is such frustrating. :doge:
