How to Install Castle APK on Firestick

These steps work on Fire TV Stick 4K and other Fire TV devices. Menu names vary slightly by Fire OS version.

Steps

  1. On your Firestick, open Settings, then My Fire TV, then Developer Options. Turn on Apps from Unknown Sources. On newer Fire OS versions, Developer Options is hidden until you select your device name in About several times.
  2. From the Amazon Appstore, install the Downloader app.
  3. Open Downloader and enter the download address for the Castle APK file, then download it.
  4. When the download finishes, select Install. Then select Open, or find the app in Your Apps and Channels.
  5. If the app will not install, check your free space first. Clearing an app cache helps: Settings, Applications, Manage Installed Applications, pick an app, Clear cache.

One warning

Only download the APK from a source you trust. Avoid modified (MOD) versions: altered files can hide malware.
