Argon in Listening Mode after code succesfull flash

I am having problems with one Argon. The bidir sticker is dirty and the app does not read it but yesterday I setup using serial and this

The code was running but today it was not, I re-flashed and it says “Flash success!” but goes to Listening Mode and the code does not run.
I factory reseted, repeated the manual above, flash using DFU etc, but with no result.

Might be useful to say that “particle serial list” detects it in COM12 but “particle serial identify” says “Serial problems, please reconnect the device.”. But power down and restart does not work there.

How can i solve this, or restart the particle to “other” factory values?

Thanks in advance,
