Yeah, I've asked a lot of questions in a short time, but you got to start somewhere

So,
I've finally rooted my TV sucessfully
In order to use this app (https://forum.samygo.tv/viewtopic.php?f=63&t=8760), I have to export my TV channel list by doing:
Main Menu->Broadcasting->Channel Settings->Transfer Channel List->Export to USB
However, at channel settings, there is no option called: "Transfer Channel List".
How could I export my TV channel list?
