Step 1: Install Downloader
From the Fire TV home screen, select Find or the search icon. Search for Downloader, choose the recognised orange Downloader application and install it.
Step 2: Allow Installation When Required
Open the Fire TV settings and find the installation permission for Downloader. Allow it to install the supplied app. Menu names differ between Fire OS versions, so ask support if you cannot find the option.
Step 3: Enter the Downloader Code
Open Downloader and enter:
Downloader code: TELVIS
Check that the displayed download belongs to Telvis. Do not install files from unrelated search results or unverified messages.
Step 4: Download and Install
Start the download, wait for it to finish and select Install. Once installation completes, open the app. You can delete the downloaded installation file afterwards to recover storage.
Step 5: Sign In
Enter the username, password and any server information from your welcome message. Credentials are case-sensitive. Avoid adding spaces before or after a field.
Step 6: Allow the First Load to Finish
The first sign-in may take longer while live, movie, series and EPG data load. Keep the app open until the update finishes.
