Google "hdb 2019 gold" and the first result is a link to firmware with IPTV streaming built in looks like it would be pretty easy
If it's still new, download the latest software and upgrade it and i'm sure you will have a 6 or 12months of free IPTV and Forever server will be enabled, other than that go to the menu and go to the apps section where you can find youtube and internet related stuff, there you will find an app to login your xtream code credentials.
Is this box dvb-s2 and the iptv servers they give you. Does it not mean it delivers cccam, which unscrambles live satellite channels. I use this in my box which also has android but I use android for iptv which is 2 different TV sources.
there is either a secret menu, or a pass code to get into the real settings. Once you gain access to where the real settings are you should be able to modify them. HOWEVER, you're probably better off sending it to recycling and picking up and Chromecast or Firestick as it is a better device and doesn't have those restrictions.
