StbEmu Setup Guide 2026 — Stalker Portal MAC Address Configuration

StbEmu turns an Android phone, TV box, or Android TV stick into a MAG set-top box, so it can open stalker portals that ordinary M3U players cannot read. Setup comes down to three fields: the portal URL, a MAC address, and a matching STB model. Get those three right and the channel list loads in under a minute. Get one wrong and you see an authorization error with no explanation of which field failed.

This guide walks through the whole configuration on a real Android TV box, then covers the errors that actually show up in practice: portals that reject your MAC, portals that only answer requests from one country, and portals that load once and die a week later.

Short answer: how do you set up StbEmu?

Install StbEmu from Google Play, open the profile list, and create a profile. Paste the portal URL into Portal Settings, then enter the MAC address in STB Configuration. Pick the STB model the provider specified, set your time zone, and restart the profile. The portal loads its own interface and channel list.

What is StbEmu and why is it not an M3U player?

StbEmu is an Android app that emulates the firmware of a MAG set-top box, the hardware line built by Infomir. It does not play a playlist file. It pretends to be a MAG box, connects to a stalker middleware server, and renders whatever interface that server sends back.

That difference matters more than it sounds. An M3U player downloads a text file full of stream URLs and builds its own menu. A stalker portal keeps the channel list on the server, tied to a specific MAC address, and hands the client a session token. The provider can change the lineup, revoke your access, or expire the MAC without touching anything on your device.

If you only have a playlist file, StbEmu is the wrong tool. Use a player that reads a free M3U playlist instead. StbEmu is for MAC based access, and our stalker portal codes page is where those portal and MAC pairs are published.

What you need before you start

Four things, and the provider has to supply the first two:

• Portal URL. Usually ends in /c/, /c, or /stalker_portal/c/. It often includes a port number.
• MAC address. Almost always starts with 00:1A:79, which is Infomir’s registered hardware prefix. A portal that expects a MAG box will refuse a MAC from any other prefix.
• An Android device. Android TV box, Android TV stick, phone, or tablet. Any reasonably modern Android build runs it; check the app’s requirements on its Play Store listing if your box is old.
• A remote or mouse you can navigate with. Portal interfaces are built for a MAG remote, not a touchscreen, and some menus are unreachable by tapping.

How do you install StbEmu on Android TV or a TV box?

StbEmu ships in two versions on Google Play: a free build and StbEmu Pro, a paid build without ads. Both configure portals the same way, so start with the free one and pay only if the ads bother you.

1. Open Google Play on the box and search for StbEmu.
2. Install it. On Android TV the free build sometimes does not appear in the TV Play Store; in that case install it from the Play website on your phone and pick the box as the target device.
3. Launch the app once so it creates its config directory.
4. If your box has no Play Store at all, sideload the APK with a file manager and allow installs from unknown sources for that manager only.

The same install pattern applies to most players on a box like this. If the box itself is new, our Android TV box setup guide covers the device side first.

How do you add a stalker portal and MAC address in StbEmu?

All configuration lives in one profile. Press the menu button on the remote, or long press anywhere on screen, to open the settings drawer.

Create the profile

Go to Profiles, add a new profile, and name it after the provider. Keep one profile per portal. Editing a working profile to try a second portal is how people lose a setup that was fine.

Enter the portal URL

Open Portal settings and paste the URL into the Portal URL field:

http://portal.example.com:8080/c/

Three details break this step more often than anything else. The trailing slash after /c is required by some middleware builds and ignored by others, so try it both ways before assuming the portal is dead. The port number is part of the address and cannot be dropped. And http is not interchangeable with https: use whichever the provider wrote.

Set the MAC address

Still in the profile, open STB configuration and replace the default MAC with the one from your provider:

MAC address: 00:1A:79:4B:2C:8E

Leave the format exactly as shown, uppercase hex with colons. StbEmu generates a random Infomir MAC on first run, and that random MAC is not registered on any portal, so it will always fail.

Match the STB model, serial, and device ID

The STB model dropdown decides which firmware StbEmu imitates. MAG250 is the safe default and the one most portals were provisioned against. If the provider named a model, use that one instead, because some portals check the reported firmware and reject anything unexpected.

Serial number and Device ID fields sit just below. Most portals ignore them. A minority bind the MAC to a specific serial and device ID pair, and those portals return an authorization error until all three match. If your provider sent a serial, enter it; if not, leave the generated values alone.

Set the time zone

Open the Advanced section and set the time zone to your own. StbEmu reports it to the portal, and the portal builds the EPG around it. A wrong time zone produces a channel list that works and a guide that is hours out of step. Related settings for the guide itself are in our IPTV EPG setup guide.

Restart the profile

Back out of settings and reload the profile, or close and reopen the app. StbEmu does not re-authorize on the fly. The portal screen should appear within a few seconds, drawn by the provider rather than by the app.

Why does StbEmu show an authorization error?

StbEmu reports almost every failure the same way, so the message tells you little. Work through the causes in this order, cheapest first.

The portal only answers requests from one country

Many stalker portals are provisioned for a single market, and the server is configured to answer only IP ranges from that country. From anywhere else the server drops the request, and StbEmu shows the same generic authorization error you would get from a bad MAC. That is why a portal a friend swears is working can fail on your box with identical settings.

You can identify this case by testing the portal URL in a browser on the same network. If the browser also times out or returns nothing while the provider confirms the MAC is active, the block is on the network path, not in your configuration.

The fix is to reach the portal from an IP inside its own country, which means routing the connection through a VPN server located there. Connect to a server in the portal’s country, then reload the profile in StbEmu; the portal now sees a local IP and completes authorization normally. A VPN with servers in the country you need, such as PureVPN, is enough for this. We may earn a commission if you buy through this link, at no extra cost to you.

Channels load but stutter every few minutes

Stalker streams are usually high bitrate, and a portal that authorizes fine can still stutter. Before assuming the provider is oversold, check whether your connection is the constraint: run a speed test on the box, and watch whether the stutter clusters in the evening.

Evening-only buffering on a connection that tests fast points at traffic shaping rather than bandwidth. Some ISPs identify continuous video traffic and cap it, which produces exactly this pattern. Encrypting the stream removes the signature the shaper matches on, so the traffic is no longer singled out, and that is one reason people running MAC portals keep a VPN on the box permanently. Our IPTV buffering fix guide works through the other causes, including Wi-Fi interference and undersized box hardware, which are more common than throttling and cost nothing to rule out.

The portal worked yesterday and is gone today

Free MAC portals expire. Providers rotate MACs, hit their concurrent connection cap, or shut a server down. Nothing on your device changed, and no setting will bring it back. Our stalker portal checker tells you whether a portal is still answering before you spend time re-entering it. Keep two or three profiles configured against different portals so a dead one is a two-click switch rather than a re-setup.

How do you make a stalker portal last longer?

You cannot control the provider’s side, but a few habits help.

• One device per MAC. Portals count concurrent connections per MAC. Two boxes on one MAC usually knocks both offline.
• Do not share the pair. A MAC that circulates widely hits its connection cap and gets revoked.
• Leave the STB model alone once it works. Changing it re-triggers the firmware check.
• Export the profile. StbEmu can write its config out to a file. Keep a copy so a factory reset does not cost you the setup.
• Avoid overnight idling. Some portals count an open session against the cap even when nothing is playing.

Free portals are unpredictable by nature; that is the tradeoff for not paying. If you need a lineup that stays up, a paid subscription with a support channel is the honest answer, and our IPTV codes page lists what is currently working on the free side.

FAQ

Is StbEmu free?

Yes. The standard StbEmu build on Google Play is free and supports ads. StbEmu Pro is a paid build that removes them. Both handle portal and MAC configuration identically, and neither includes any channels.

Why does StbEmu need a MAC address?

Stalker portals identify clients by MAC rather than by username and password. The provider registers a specific MAC on their server and ties your channel package to it. Without a registered MAC the portal has no record of you and refuses the session.

What MAC address should I use in StbEmu?

Only the one your provider issued. It normally begins with 00:1A:79, Infomir’s hardware prefix for MAG boxes. Randomly generated MACs, including the one StbEmu creates on first run, are not registered on any portal and will always fail authorization.

Can I run StbEmu on a Firestick or a Smart TV?

Firestick runs Fire OS, which is Android based, so StbEmu can be sideloaded. Samsung and LG Smart TVs run Tizen and webOS and cannot install Android apps at all, so StbEmu is not an option there. Those sets need a Tizen or webOS IPTV app, or an Android box connected over HDMI. Our Smart TV setup guide covers the Tizen and webOS route.

Which STB model should I select?

MAG250 unless your provider specified otherwise. Most portals were provisioned against MAG250 firmware. Some check the reported model and reject anything else, which is why matching the provider’s instruction matters when they give one.

Why does the portal load but no channel plays?

Authorization and streaming are separate steps. A loading portal means the MAC was accepted; a channel that will not start points at the stream servers instead. Test a second group of channels first. If nothing plays anywhere, the subscription content behind the MAC has probably expired even though the MAC itself is still valid.

Conclusion

StbEmu configuration is three fields and a restart. When it fails, the app gives you one vague error for a dozen different causes, so the work is in narrowing it down: verify the MAC character by character, confirm the portal URL and its port, test whether the portal is reachable from your network at all, then check the country restriction and the time zone. Keep a second portal profile configured, because free MAC portals go dark without notice and a spare profile turns that into a two-click switch.
