I have downloaded the binary, but cannot upload to Elektron.  
Basically I have the same problem as here [Particle CLI cant load Firmware Binary - Electron - AT&T data card [Solved]](https://community.particle.io/t/particle-cli-cant-load-firmware-binary-electron-at-t-data-card-solved/20515), except reinstalling nodejs and particle cli does NOT solve the problem.

So I downloaded the firmware binary and trying to flash it to Elektron via USB using Linux Mint and particle cli.

```nohighlight
myuser@laptop ~/Documents/Particle $ nodejs --version
v0.10.37
myuser@laptop ~/Documents/Particle $ particle --version
1.11.0
myuser@laptop ~/Documents/Particle $ particle identify

Your system firmware version is 0.4.8
myuser@laptop ~/Documents/Particle $ particle flash --serial blink.bin
! PROTIP: Hold the SETUP button on your device until it blinks blue!
? Press ENTER when your device is blinking BLUE 
sending file: blink.bin

```

What I am doing wrong?  
What NodeJS / particle cli version am I supposed to be using?

After upgrade nodejs to v0.10.43, the latest in the 0.10.x series the issue is still there.

v0.10.43 is rather old by now. 0.12.7 is old already which used to work just fine. I believe node is at 5.7.1 by now, which would be worthwhile trying?

Thanks, you were right. After a few trials I finally suceeded with node v5.7.1;

$ particle flash --serial blink.bin  
! PROTIP: Hold the SETUP button on your device until it blinks blue!  
? Press ENTER when your device is blinking BLUE  
sending file: blink.bin

Flash success!  
Aborted

ps.: also tried the 0.12.x series, no luck there either.
