So I have a Toshiba TV that has Android TV built in and its abit laggy and I dont like all the ads and I cant hide some apps. I have installed other launchers and using button mapper to switch. However is there a way to permanently change the launcher?
You can use ADB to disable the stock launcher, but the exact apps to disable would depend on your specific device somewhat.
The FLauncher documentation gives the commands for the CCwGTV for a starting point.
Yes. Use an app called Launcher Manager. It allows you to select a custom launcher and to always boot with it on power up.
This is a quick way to get it on there:
What version of android tv does it have?
