How to Setup IPTV on Amazon Fire TV
The Sub-Device app works perfectly on Amazon Fire TV Stick
To install Perfect Player on Amazon Fire, follow these instructions:
On your Amazon Fire home page, press Up to select the navigation tabs. Scroll to the right until you reach the Settings option and click on it.
Select Device > Developer Options. Scroll down to the option “Apps from Unknown Sources” and make sure it says ON (click on it if it doesn’t).
Launch the Amazon Fire Store and search for Downloader.
Click on the Downloader icon and then press Install. Allow Downloader any permissions it requests. When it is done downloading, click Open to launch it.
In the URL text box, enter in www.bestiviewhdiptv.com/app/stbpsub
Downloader opens up this page just like a web browser does.
Click on the latest APK file, the one at the top of the page.
Just like when you downloaded Downloader, you may be asked to allow the application access to your Amazon Fire.
The iviewHD Plus Sub-Device APK will first download and then prompt you to install.
