Not quite you don't.Ok I get it.
The latest released version of the CF (mod3.13) does not have iplfix functionality, nor are any packages pre-installed - you need to install iplfix.There is no point in updating to the latest firmware as the custom firmware includes the iplfix package which basically preinstalls what the official firmware does.
iplfix is most definitely dated 2021, I assure you, as Humax didn't release the updates until this year. Maybe you are thinking of iplhack which was from last year and is now obsolete.The only reason I asked was because the official firmware was dated 2021 where as the iplfix was dated 2020.
Irrelevant for practical purposes.Also the customer firmware was dated 2017.
You can do it with the ir package, but start (or continue) another thread for that.Given a choice I would rather repurpose the TV Portal button to do something more useful but as I don’t have a clue how to do that I think I will just avoid pressing it.
