Please visit our community forums for help with this error:

i tried searching the forum on keyword device id_ec_new.der
but nothing came up. a search with google on the net also on
keyword device id_ec_new.der also had no hits.
however you will notice that in the error message itself the word
successfully is spelled wrong.

the device when reset goes from breathing white to blinking green.
i do have a battery attached as well as plugged into usb. this electron
has been operating with no problems for a ~week. i get the same error
message if i run a standalone particle keys doctor

Hi @dkryder,

The CLI wants you to replace the text “device id” with the device id of your device. Put your device into listening mode (hold setup button until the led blinks blue), and run particle identify.

Thanks,
David

yes, i’m aware of that. i was using the term as a placeholder for the actual id in the error message.

does anyone know what directory the file 44002c000xxxxx37353037_ec_new.der would be?
otherwise file deviceID_ec_new.der running keys doctor throws the error that it can not find that file.
