Fire TV Stick 4K Max Setup

There are two install paths for DisplayCache on Fire TV. Standard Install covers three out of every four deployments and works with just the remote and ~10 minutes. Kiosk Mode adds a one-time ADB step that physically disables the Home button — use it when accidental Home presses are a real risk.

Within Standard Install: where does the remote live?

This isn’t a separate install — it’s an operational choice you make after the install is done, depending on the deployment:

• Remote nearby — back-office screens, sound booths, anywhere staff control the remote. Pressing Home exits to Fire OS, which is exactly what staff want for quick maintenance.
• Remote hidden — lobbies, classrooms, public-facing displays. Tuck the remote in a locked drawer. The app keeps running on boot, and without a remote no one can press Home. This is what we recommend for most public-facing screens.

Not sure? Pick Standard Install and hide the remote when you mount the screen. It covers 99% of the customers we’ve set up. Move up to Kiosk Mode only if you have a real reason a passer-by would have a Fire TV remote on them.

The first few sections below are common to both install paths. Stop reading at Step 6 if you’re doing Standard Install. If you’re doing Kiosk Mode, do Steps 1–5 anyway (or skip straight to the Kiosk Mode section at the bottom — both work).

Have these ready before you plug in the Fire TV. The whole setup takes about 20 minutes.

1. A DisplayCache account. If you don’t have one yet, sign up at displaycache.com. Free trial, no credit card.
2. Your Wi-Fi password. The Fire TV asks for this during its first-boot setup.
3. A dedicated Amazon account for your signage. See the section right below this one — it’s the single biggest thing that prevents pain later.
4. A laptop, phone, or other device with a web browser. You’ll log into the DisplayCache admin from there to finish pairing.
5. The DisplayCache APK file. Email hello@displaycache.com and we’ll send you the latest download link plus a 2-minute walkthrough. (Once we’re live on the Amazon Appstore, this step will go away.)

Recommended: a dedicated Amazon account for your signage

Amazon requires every Fire TV to be linked to an Amazon account, but they don’t care which one. Don’t use your personal account. Set up a separate one just for the org’s screens. Here’s why and how.

Why a separate account matters

• People leave. When the person who set up the Fire TVs leaves the org (volunteer, IT staff, pastor, teacher), their personal Amazon account goes with them. The screens stay paired to a disappearing account — eventually they de-authorize and your signage stops.
• Privacy. A personal account leaks recommendations, recently-watched shows, and marketing emails onto a public display. You don’t want “Continue watching: The Crown” appearing in your lobby.
• Payments. A personal account often has a credit card on file. With the remote, anyone walking by can rent a movie or buy an app.
• Cleanup is easy. When you ever need to retire all the Fire TVs, you de-register a single dedicated account instead of trying to remember whose personal account is on which device.

How to set it up (5 minutes)

1. Pick a generic email address. Use your existing IT or admin email if you have one. Good examples: signage@yourchurch.org, displays@yourschool.edu, firetv@yourbusiness.com. If you don’t have a generic mailbox, create a free Gmail or Outlook account first — takes 2 minutes.
2. Go to amazon.com and click Account & Lists → Start here at the top right to create a new account.
3. Fill in the form using the generic email and a strong password. Use the org name as the name field (e.g., “First Baptist Signage”).
4. Verify the email when Amazon sends the code.
5. Skip the “add a payment method” prompt if Amazon asks. Fire TVs work fine without one. You can add a corporate card later if you ever want to buy something from the Appstore.
6. Save the credentials in your password manager. 1Password, LastPass, Bitwarden, even a shared spreadsheet locked in a drawer — just somewhere the next IT person can find it.

One account, many Fire TVs — you sign every Fire TV the org owns into this same account. There’s no extra cost, no licensing, no setup penalty for sharing.

Out-of-the-box first-time setup. Skip this if your Fire TV is already running.

1. Plug the Fire TV Stick into your TV’s HDMI port and into power.
2. Switch the TV to that HDMI input. You’ll see Amazon’s welcome screen.
3. Follow the on-screen prompts: pick a language, connect to your Wi-Fi, sign into your Amazon account.
4. When it asks about adding streaming services, just press the remote’s right arrow to skip — you can do this later if you want.
5. You’re done when you see Amazon’s home screen with rows of recommended shows.

This part takes ~5 minutes. The Amazon account is required by Amazon, not by DisplayCache — we never see it.

This is the most important step. Fire TVs go to sleep after 20 minutes of inactivity by default, which means your signage stops every 20 minutes. Turn it off.

1. From the Fire TV home screen, press the remote’s gear icon (or scroll to the right and pick Settings).
2. Open My Fire TV.
3. Pick Sleep (newer firmware) or Power (older).
4. Set Sleep Timer to Never.
5. Go back, then to Settings → Display & Sounds → Screen Saver.
6. Set Start Time to Never.

The Fire TV will now stay awake as long as it has power.

The DisplayCache app is currently distributed as a sideload package while our Amazon Appstore submission is in review. Reach out and we’ll walk you through it.

1. Email hello@displaycache.com with subject “Fire TV install.”
2. We’ll reply within one business day with: (a) the direct APK download link, (b) a 2-minute video showing the install, and (c) the exact remote button presses for your Fire TV model.
3. Follow the video. The install itself takes about 5 minutes — mostly a one-time toggle to allow apps from outside the Amazon Appstore.
4. Once installed, DisplayCache launches automatically. You’ll see a fullscreen pairing screen with a 6-character code that looks like X7K-9M2.

The Fire TV is showing a 6-character code (like X7K-9M2). Now connect it to your DisplayCache account so you can manage what plays on it.

1. On your laptop or phone, open admin.displaycache.com and sign in.
2. Click Devices in the left sidebar.
3. Click the orange + Pair Device button.
4. Type in the 6-character code from your TV exactly as shown (the dash is optional — the form is forgiving).
5. Give it a name you’ll recognize later — “Lobby TV,” “Kids Room,” “Front Desk.”
6. Click Pair.

Within a few seconds, the pairing code on your TV disappears and the screen changes — either to a holding screen (“Waiting for content”) or to whatever you have scheduled.

Now put something on the screen. There are two ways:

• Assign a playlist directly. Quickest. The same playlist plays 24/7. Good for “always show our weekly slides.”
• Use a schedule. More flexible — different content at different times of day or week. Good for “Sunday morning announcements 9am-noon, then a different playlist the rest of the week.”

Both options live under Schedules and Playlists in the admin sidebar. The first time you set this up, start simple: upload a few images, create one playlist, assign it to your Fire TV. You can always add scheduling later.

Once you save, the Fire TV downloads the content and starts playing within 1–2 minutes. After that, anything you change in the admin pushes to the Fire TV automatically — you don’t touch the remote again.

For public-facing displays (lobbies, classrooms, hallways), put the Fire TV remote in a drawer. The app starts automatically on boot and runs without any remote input. If someone with a remote presses the Home button, they’ll exit to the Fire TV home screen — tucking the remote away is the simplest prevention.

For tighter control (the screen literally can’t be exited even with a remote), see Advanced: Kiosk Lockdown at the bottom of this page.

For deployments in public or semi-public spaces — a lobby, a hallway TV, a classroom display where curious people might press buttons — you can lock the Fire TV Stick into full kiosk mode. The Home button stops working, Recents is hidden, and DisplayCache is pinned to the screen until an admin unlocks it.

What you’ll need

• A brand new or factory-reset Fire TV Stick. The kiosk activation only works before any Amazon account is signed in.
• A Mac, Windows, or Linux laptop on the same Wi-Fi network as the stick.
• Android Debug Bridge (ADB) installed (download from Google; macOS users can also brew install android-platform-tools).
• The current DisplayCache APK file (we’ll send this to you separately when you request kiosk provisioning).

Provisioning steps

1. Factory-reset the Fire TV Stick (Settings → My Fire TV → Reset to Factory Defaults), or skip this for a brand-new device.
2. During the setup wizard, get the stick onto your Wi-Fi network but do not finish signing in to your Amazon account yet. Note the device’s IP address (Settings → My Fire TV → About → Network).
3. Enable Developer Options:
   • Go to Settings → My Fire TV → About.
   • Click your device name (Fire TV Stick 4K Max) seven times to unlock the developer menu.
   • Back out one level → Developer Options → turn on ADB Debugging and Apps from Unknown Sources.
4. From your laptop terminal, connect and install:

   adb connect <FIRE-TV-IP>:5555
   adb install displaycache-firetv.apk
   adb shell dpm set-device-owner com.displaycache.player/.DeviceAdminReceiver

5. The last command is the one that activates kiosk mode. If it returns Success: Device owner set..., you’re locked in. If it errors with "a user is already on the device", the stick wasn’t fresh enough — factory-reset and start over.
6. Open DisplayCache from the Fire TV launcher one time. It will pin itself to the screen on first launch and on every boot afterward.

Unlocking the device

To exit kiosk mode (for maintenance, troubleshooting, or to retire the device), run:

adb connect <FIRE-TV-IP>:5555
adb shell dpm remove-active-admin com.displaycache.player/.DeviceAdminReceiver

The stick returns to normal Fire TV behavior. Re-provisioning later requires a factory reset.

Updating a kiosk-mode device

DisplayCache self-updates automatically. When a new build is published, every paired Fire Stick downloads and installs the update on its next manifest poll (within 30 minutes). In kiosk / Device Owner mode the install completes silently and the app relaunches itself — no remote interaction or ADB push required.

If you ever need to force an update or roll back manually:

adb connect <FIRE-TV-IP>:5555
adb install -r displaycache-firetv-vX.Y.Z.apk
