My Particle Electron has been working fine until recently when I was trying to put into DFU mode (to flash a program, since it was not allowing over serial), where I mistakenly released and pressed setup button.
This was followed by some red flashes.
I have updated the firmware using particle firmware manager and also from command line using ‘Particle Update’, following the update the device flashes continuous blue. When I press reset, the device tries to reset by flashing various colours followed by red flashes and finally flashes continuous blue.
As the device was flashing continuous blue, I also tried to flash a program from the serial port to see if it makes any difference, the device responds to the flash (CLI says flash is success) but device soon goes back to flashing continuous blue.
I also notice that this behaviour is not consistent.
Could some one please advice how I could resolve this ?
