Electron enters directly Listening Mode when trying to connect to Cloud

Troubleshooting
1

My particle always directly going to Listening Mode when trying to connect to the Particle Cloud without blinking green first. Of course a SIM-Card is installed. I also tried to remove the SIM and insert it again with the same result.
I was on 0.5.3 and tried to update to the current Firmware 0.6.2. It states that it was correct but if I try the following in Listening Mode:

$ particle identify

Your device id is 40005e000351353337353037
Unable to determine system firmware version

and

$ particle serial identify

Your device id is 40005e000351353337353037
Unable to determine system firmware version

So not sure how to proceed here as it is always entering listening mode even with Tinker App.

How did you try?

$ particle update

> Your device is ready for a system update.
> This process should take about 30 seconds. Here goes!

! System firmware update successfully completed!

> Your device should now restart automatically.

Can you try

particle serial inspect

and post the result?

I tried it lots of times in Listening mode and got two different results. For me the occurrence of both was completely random:

$ particle serial inspect

! serial: Serial timed out

$ particle serial inspect

! serial: SyntaxError: Unexpected end of JSON input

Could you try placing the device into Safe Mode first and then enter Listening Mode from breathing magenta?

Not possible. So I hold down both buttons and release the reset button. No if it blinks magenta I release the mode button but immediately it jumps back into my application code and does not breathing magenta.
