Particle CLI cant load Firmware Binary - Electron - AT&T data card [Solved]

I can download the Binary but cannot seem to get it into the Electron.

I go from Blinking Blue to solid Blue LED back to Blinking Blue with this error:

! PROTIP: Hold the SETUP button on your device until it blinks blue!
? Press ENTER when your device is blinking BLUE 
sending file: firmware.bin

Have you got the most recent version of CLI?

npm update -g particle-cli

yes, updated.

I can see the device, but I cannot make it flash:

:confounded:

EDIT: I have both files that downloaded in their own folder whilst I use:

particle flash --serial firmware.bin

Reinstalled Node.js, updated Particle CLI and it flashed.

What version of node are you using that works? I’m having the same issue, on v0.10.33.

This is way too old.
At one instance a few months back I had to upgrade to somthing higher than 4.0.0
