Is using a toothpick every time you want to boot to LibreELEC not your thing?
The solution is very simple, according to the LibreELEC forum it's very simple. Just run a command and done.
But what if you dont have a keyboard? Or just too lazy to type it in every time?
This is the solution!
What the app does is very simple. it runs the "reboot update" command as root.
Want to know alternatives to boot to LibreELEC?
