How to Install IPTV on a Formuler Box (UK Guide 2026)

Formuler boxes use MyTVOnline, which is already on the device. You add a portal or an Xtream login. You do not install a random APK.

MyTVOnline 2 and MyTVOnline 3 use the same idea with slightly different button names. The steps below name both.

In short

What you need

Recommended app

Use TiviMate. MyTVOnline is the player on the Formuler. If you also watch on a Firestick, TiviMate is the matching guide-style app. Other players that also work: IPTV Smarters Pro .

Step by step

  1. Open MyTVOnline

    From the Formuler home screen open MyTVOnline. On MyTVOnline 3 the add button is a plus on the portal row. On MyTVOnline 2 open Content Manager or the portal list.

  2. Add a portal

    Choose Add portal. Set the nickname to BestUK. Paste the portal URL from the welcome message into the URL field. Save.

    Add portal form with nickname and URL
  3. Or add Xtream Codes

    If you were sent a username instead of a portal, choose Xtream Codes or Add playlist. Enter the name, username, password and server URL. This replaces the portal step. You only need one of the two.

  4. Open the portal and load the guide

    Select the new portal and wait for live TV, films and the guide. If the list is empty, reboot the Formuler once. Set the box timezone to London so the guide times match.

Log in to your subscription

You can add a portal with a nickname and URL, or sign in with Xtream Codes. Use whichever your welcome message includes. Do not enter both unless you mean to keep two playlists.

Xtream Codes API (preferred)

Any name you will recognise.

Paste the username from the welcome message.

Paste the password. It is case sensitive.

Replace this with the server URL from your email or WhatsApp.

Portal

Paste the portal URL from your welcome message, then save and reboot.

M3U URL

Use this if the app has no Xtream Codes button. Replace USER and PASS.

Only needed when the app asks for a separate programme guide.

Problem, likely cause and what to try.
Problem Cause Fix
Buffering The Wi-Fi drops, or the stream is 4K on a line that cannot hold it. Use the LAN port. Formuler boxes are often tucked behind the TV, where Wi-Fi is poor. FHD is the fallback if 4K stalls.
Black screen The player opened the stream but the video decoder failed. Reboot after adding the portal. A black screen with a loading spinner usually clears on the second boot.
Login failed A username, password or URL was typed with a space or a missing character. Check you used the portal URL in the portal form, or the Xtream URL in the Xtream form. They are not the same address.
EPG not loading The guide URL is empty, or the device clock is wrong. Update the guide from the portal menu. If it stays blank, the account has only just been added. Wait two minutes and open the guide again.
App not installing Unknown sources are off, or the store cannot see the app. Do not install a second IPTV app from a browser on the Formuler. MyTVOnline is the supported path.
Guide times are an hour out The EPG offset does not match UK time, or daylight saving has changed. Timezone London and an EPG offset of 0 match UK listings. Reboot after the clocks change.

Formuler questions

Which Formuler models use MyTVOnline?

The Z series boxes that ship with MyTVOnline 2 or 3. If your box has a different home screen, tell us the model before you add a file from the web.

Portal or Xtream: which should I pick?

Use the one in your welcome message. If both were sent, the portal is the native Formuler path. Xtream is fine if you already use it on another device.

Can I add a second portal for another room?

You can add another playlist on this box. A second screen playing at the same time still needs another connection on the plan.

The box already has a portal. Will this remove it?

No. Add BestUK as a new portal and leave the old one in the list.
