Wondering if anybody has had any luck finding these ESPN channels Deep Links for the ESPN App or Disney+ App?
I think the Hulu standalone app will be phased out this year, so this will probably will stop working when that happens and need Disney + or ESPN+ Deep Links.
Update: There is one thing that is a little annoying, when the Hulu app goes idle, it asks you to select a profile on startup. Updated to the latest ADB 20260228-1 and wasn't having the issue anymore, the tuners are able to move past The "Who's Watching" profile screen.
Below was some testing I did, but no longer needed.
I created a custom ADB configuration to test a few things to get around this:
"pre_tune_commands"
Added "input keyevent 66" to press "enter" when ADB opens Hulu to get past the select profile screen.
"post_tune_commands"
Modified with a double "input keyevent 4", so my fire tv presses "back twice" on exit, so the Hulu app doesn't close and launches quicker. Might need to do some trial and error here to see what works best for your setup/preference.
Note: I've updated my fire tv's to not sleep with the "settings put system screen_off_timeout 2147460000" command, that is also explained below:
