1 year after IoT.... Redbear duo looks difficult to install now

I got it work before. I started to play Xbox, watching youtube movies, enjoy vacation, etc.
Now, my redbear can’t go back particle.io I got the particle key.
I forgot document and fix it. I followed this. looks way difficult.
What I do now?

Po-Util works great with core, pi but… There is no particle cli tool for Redbear.
It Didn’t work.

Have you tried logging back into particle-cli?

$ particle cloud login

I need tutorial how to DFU redbear.

With po-util?

Do whatever is possible on po-util. I removed particle device from IDE.
I want to see if po-util can do better job than dfu and particle cli.

This one failed… loss blinking light and can’t get in Particle IDE.
