Particle P1 breathes white... AGAIN!

Double posting the same issue is not appreciated here

CLI doesn't work anymore!

I had installed CLI previous version (it was fully operational) and yesterday during opening it a message that a new version xxxbbbbbrrrrttt (or something) is available, indicated. I tried to make update and from then everything in CLI does not work. Previously particle shown as “particle” and now is shown as “.particle” plus a new dir “particledev”. What happens? 4 days ago, i had connected Photon with RS485 interface, loaded a library and during power-up Photon fried!

Hence I locked the other topic, not to waste other people's time supplying the same answers multiple times scattered all over the forum.
