Hi and thank your for keeping this old device alive!
I have recently installed LibreElec on my Wetek Play 2 following this guide:

So far so good.
When I try to shut it down, it keeps rebooting.
I can see the red standby LED turning on for a few seconds, but then it switches to blue and the device starts again.
