Install guide
A few minutes, once. You only need the free Downloader app: no computer, no cable and no developer tools.
All Channels needs a Fire TV running Fire OS 6 or later, such as a Fire TV Stick 4K or 4K Max. On your Fire TV, open the settings path below: it needs to say Fire OS 6 or higher.
Amazon's newer Vega OS devices, such as the Fire TV Stick 4K Select, can only install apps from the Amazon Appstore, so All Channels can't run on them.
From the Fire TV home screen, choose the search icon, look for Downloader (a free app made by AFTVnews), and select Get. Open it once it has installed.
Fire TV only installs apps from outside the Appstore if you allow it, and on Fire OS 7 and later you allow it for Downloader alone. On Fire OS 6 the switch covers all apps, so switch it off again after installing.
On older Fire OS the switch is called Apps from Unknown Sources. If there's no Developer options, open About and select your device's name seven times, then go back. You don't need ADB debugging; leave it off.
Open Downloader and select the URL box. Type the short personal address you were given when you bought All Channels, then press Go. When the download finishes, select Install.
Once it says App Installed, select Done, then Delete to remove the downloaded file and keep your Fire Stick's limited storage tidy. This doesn't uninstall the app. You can switch Downloader's install permission off again now.
Open All Channels from your apps. Scan the QR code on the screen with your phone's camera, then enter your provider's Xtream Codes login or M3U link on your phone's keyboard. Prefer the remote? You can type it on the TV instead.
Scan the code to open this page on your phone while you work through the steps on your TV.
Afterwards
Install the new version the same way as in step 4. It normally replaces the old one and keeps your login, favourites, watch history and reminders. Don't uninstall first.
The new version can't replace the All Channels already on your Fire Stick, usually because the two came from different sources. An older version won't install over a newer one either, so check you have the latest link.
As a last resort you can uninstall the old copy (long-press the app icon, then Uninstall). That deletes your login, favourites, history and settings for good, so you'd set up again.
Check the server address starts with http:// or https:// and includes the right port, and that your username and password have no stray spaces. If your internet provider blocks yours, try a VPN or switch on Encrypted DNS in Settings, Network.
The player tells you why, for example that your subscription has ended, that too many devices are using the account, or that the channel is offline at the provider. A short technical line underneath is worth quoting to your provider.
In Settings, raise the buffer size. If it's still poor, try with and without your VPN to see which side is the bottleneck.
