Device identifier
Find your TV MAC address for FoxAPP
Use the MAC or UID shown inside FoxAPP, not a guessed value from TV settings. That identifier is what activation expects.
Open FoxAPP on the TV
Install FoxAPP on a Samsung Tizen or LG webOS TV and open it. The first screen usually shows the MAC or UID.
Copy it exactly
Keep colons and letter case as displayed. Do not type a MAC from TV settings unless it matches FoxAPP.
Samsung Tizen
Search FoxAPP in the Samsung app store, open the app, then copy the identifier from the FoxAPP screen.
LG webOS
Search FoxAPP in the LG Content Store, open the app, then copy the identifier from the FoxAPP screen.
