Cast4K IPTV Setup Guide —
MAC Portal on Every Device
Setting up Cast4K IPTV takes two things: your device MAC address registered with us, and our portal URL entered in your app. This guide shows exactly where to find the MAC and where to type the portal on MAG, Formuler, STB Emulator, Fire Stick and Samsung or LG smart TVs. New here? Start with the free 48-hour trial.
Before You Start
How a MAC Portal Line Works
Cast4K IPTV (also known as Stream4K) does not use usernames, passwords or M3U playlists. Three pieces fit together instead.
2
Activation on Our Side
We register a trial or paid line on that exact MAC. Only that device can open the portal, which is why one subscription covers one device.
3
The Portal URL
After activation we send the portal URL privately on WhatsApp. You type it in your app once, and it stays the same when you renew.
Why the portal URL is not on this page: it is shared only with activated customers and trial users on WhatsApp. If anyone else gives you a "Cast4K portal", it is not from us. Get yours from the Cast4K IPTV free trial or a Cast4K IPTV subscription.
MAG Box
How to Set Up MAC IPTV on a MAG Box
Works on MAG 250, 254, 256, 322, 324, 424, 520 and 524. Menu names can differ slightly between firmware versions.
Where to find the MAC address
Turn the box over: the MAC is printed on the sticker underneath and starts with 00:1A:79. You can also see it in Settings → System information (or the Status screen on newer models).
Where to enter the portal URL
- Find the MAC address: Read the MAC address from the label underneath the MAG box (it starts with 00:1A:79) and send it to Cast4K IPTV on WhatsApp.
- Open portal settings: On the MAG home screen open Settings, then Servers, then Portals.
- Enter the portal URL: Type a name in Portal 1 name and enter the portal URL sent to you on WhatsApp in Portal 1 URL.
- Save and restart: Save the settings and restart the box. The Cast4K IPTV portal loads with the channel list.
Tip: on MAG, leave Portal 2 empty unless you use a second provider, and make sure the URL has no space at the start or end.
Formuler
How to Set Up MAC IPTV on Formuler MyTVOnline
Formuler boxes use the MyTVOnline 2 or MyTVOnline 3 app for portal services.
Where to find the MAC address
Open MyTVOnline. The MAC address is displayed in the app (on the Connections screen and in the device information). Formuler MACs often start with 00:1A:78; send it exactly as shown.
Where to enter the portal URL
- Find the MAC address: Open MyTVOnline 2 or 3 on the Formuler and note the MAC address shown in the app, then send it on WhatsApp.
- Add a portal: In MyTVOnline go to Connections and choose Add portal.
- Enter name and URL: Enter any portal nickname and the portal URL sent to you on WhatsApp.
- Connect: Select Connect. MyTVOnline downloads the channel groups and the program guide.
Tip: if the connection hangs on "loading", edit the portal, check the URL, and reconnect. MyTVOnline also lets you hide channel groups you do not watch.
Android & Fire Stick
How to Set Up MAC IPTV on STB Emulator and Fire Stick
STB Emulator turns an Android phone, tablet, TV box or Amazon Fire TV Stick into a MAG-style portal player.
Installing on Fire TV Stick
STB Emulator is not in the Amazon Appstore, so install the free Downloader app first, then enable Settings → My Fire TV → Developer options → Install unknown apps for Downloader, and use Downloader to install STB Emulator. On other Android devices you can install it from Google Play.
Where to find the MAC and enter the portal URL
- Install STB Emulator: Install STB Emulator on your Android device. On Fire TV Stick, install the Downloader app from the Amazon Appstore, allow apps from unknown sources for Downloader, and install STB Emulator with it.
- Check the MAC address: Open Settings, Profiles, select your profile, then STB configuration, and note the MAC address. Send it to Cast4K IPTV on WhatsApp.
- Enter the portal URL: In the same profile open Portal settings and enter the portal URL sent to you on WhatsApp in Portal URL.
- Restart the app: Go back and restart STB Emulator. The portal loads with your channels.
Tip: in STB configuration you can also pick a MAG model (MAG 250 is the usual choice). Do not change the MAC after we register it, or the portal will refuse the connection.
Samsung & LG
How to Set Up MAC IPTV on Smart STB (Samsung / LG)
Smart TVs from Samsung (Tizen) and LG (webOS) can run the Smart STB app from their app stores.
- Install Smart STB: search for "Smart STB" in the Samsung or LG app store and install it.
- Note the MAC: the app shows a MAC address on its first screen. Send it to us on WhatsApp.
- Open settings: press the Menu or Settings button on the remote and choose Settings → Portal settings.
- Enter the portal URL: type the portal URL from WhatsApp, save, and restart the app.
Smart STB has its own app license from its developer after a short free period; that fee is separate from Cast4K IPTV. Set IPTV works in a similar way: it shows a MAC address on the TV, and we help you link the portal over WhatsApp.
Troubleshooting
Common Setup Errors and Fixes
Most problems come down to the MAC, the URL or the internet connection. Work through these before contacting us.
"Authorization failed" / "STB blocked"
The MAC in your app does not match the MAC we registered, or the line has expired. Compare the MAC character by character, then message us on WhatsApp to check the line.
Portal will not load
Check the portal URL for typos, missing slashes or extra spaces. Copy it exactly from the WhatsApp message and restart the device.
Channels freeze or buffer
Clear the app cache (STB Emulator and MyTVOnline both have the option), restart your router and box, and try a wired connection. Try an HD version of the channel if 4K stutters.
Stopped working after a while
Your trial or subscription may have ended. Renewing keeps the same MAC and portal; we add the time and you just restart the app.
Changed to a new device
A new box or a reinstalled app usually means a new MAC. Send us the new MAC on WhatsApp and we will help move the line.
Still stuck?
Send a photo of the error screen and your MAC on WhatsApp. Our support team is available 24/7 and will walk you through it.
