After setting up my new Deco E4, I updated it.

When the update finished, the Deco's light started blinking yellow.

It never had the blue light again, just stuck on blinking yellow, I don't know which is the firmware version that was updated.

I tried doing the setup again follow the instructions on the Deco app, but it never worked. The app never detected the Deco device again and the network created on the app was automatically deleted.
