# firestrip

**Reclaim your Amazon Fire TV from your Linux terminal.**

firestrip is a Linux-native TUI and CLI tool that removes Amazon's bloatware, silences telemetry, swaps the launcher, and tunes device settings — entirely over ADB, no root required, no Windows in sight.

---

## Support This Project

firestrip is built and maintained by **one person**, in free time, with no corporate backing, no funding, and no team. Every device profile, every package classification, every line of the TUI was researched and written from scratch.

If firestrip:
- saved you from booting Windows just to debloat a stick
- stopped Amazon from silently fingerprinting your viewing habits
- gave you a Fire TV that actually works for *you*

— then consider buying a coffee. It takes 30 seconds and means a lot.

Donations directly fund what keeps this project alive: tracking FireOS updates, adding new device profiles, and staying ahead of Amazon's ongoing attempts to lock down ADB access. The tool is free and always will be — but if it's worth a cup of coffee to you, [you know where the button is](https://buymeacoffee.com/succinctrecords).

---

## The Problem

Amazon Fire TV hardware is genuinely good. The software is not. Out of the box:

- The launcher is plastered with ads and "recommendations" you never asked for
- Dozens of background services collect usage data, fingerprint your viewing habits via ACR, and feed an advertising ID you can't easily opt out of
- Amazon Sidewalk runs silently, sharing your device's network with strangers
- Pre-installed apps you can't remove bloat storage and RAM
- The UI is optimised for Amazon's revenue, not your experience

Every existing tool to fix this is either Windows-only, macOS-only, an unmaintained shell script, or doesn't cover Fire TV at all. firestrip was built to be the tool that should have existed years ago.

|---|---|
| `a` | Select all visible packages |
| `n` | Deselect all visible packages |
| `s` | Filter to Safe tier only |
| `p` | Preview / confirm selection |
| `Enter` | Toggle row selection |

---

## CLI Reference

```bash
# Device info
firestrip --host 192.168.1.138 device

# Debloat
firestrip --host 192.168.1.138 debloat list
firestrip --host 192.168.1.138 debloat run --preset safe
firestrip --host 192.168.1.138 debloat run --preset safe --apply
firestrip --host 192.168.1.138 debloat run --preset aggressive --apply
firestrip --host 192.168.1.138 debloat run --package com.amazon.bueller.music --apply

# Telemetry
firestrip --host 192.168.1.138 telemetry status
firestrip --host 192.168.1.138 telemetry strip --apply

# Launcher
firestrip --host 192.168.1.138 launcher list
firestrip --host 192.168.1.138 launcher status
firestrip --host 192.168.1.138 launcher scan
firestrip --host 192.168.1.138 launcher set wolf --apply
firestrip --host 192.168.1.138 launcher set wolf --apk ~/Wolf.apk --apply
firestrip --host 192.168.1.138 launcher restore --apply

# Settings tweaks
firestrip --host 192.168.1.138 settings status
firestrip --host 192.168.1.138 settings apply --apply

# APK install / uninstall
firestrip --host 192.168.1.138 apk install --path ~/MyApp.apk
firestrip --host 192.168.1.138 apk uninstall --package com.example.app

# Backup & restore
firestrip --host 192.168.1.138 backup create
firestrip --host 192.168.1.138 backup list
firestrip --host 192.168.1.138 restore --input ~/.local/share/firestrip/backups/backup.json
firestrip --host 192.168.1.138 restore --input ~/.local/share/firestrip/backups/backup.json --apply

# USB
firestrip --usb debloat run --preset safe --apply
```

Dry-run is always the default. **Nothing is changed on the device unless `--apply` is explicitly passed.**

---

## Package Classification

Every package in the database is assigned one of four tiers:

| Tier | Description |
|---|---|
| `SAFE` | Standalone. No system dependencies. Confirmed safe to disable. |
| `RISKY` | Has inter-dependencies or is OTA-related. Warned before action. |
| `TELEMETRY` | Data collection, usage reporting, advertising services. |
| `NEVER_TOUCH` | Hardcoded. Cannot be selected or disabled. Never appears in the UI. |

**Debloat presets:**

| Preset | Tiers targeted |
|---|---|
| `safe` | SAFE only |
| `telemetry` | TELEMETRY only |
| `aggressive` | SAFE + RISKY + TELEMETRY |

All operations use `pm disable-user --user 0` — the package stays on disk and can be re-enabled at any time. No permanent changes, no brick risk.

**`NEVER_TOUCH` includes** (among others): `com.amazon.tv.launcher`, `android`, `com.android.systemui`, `com.android.providers.downloads` (system download manager), live TV tuner packages on the Fire TV Box.

---

## Telemetry Stripped

firestrip applies two layers of telemetry suppression:

### Settings layer (7 overrides)

| Setting | Effect |
|---|---|
| `global/amazon:device_metrics_opt_in = 0` | Opt out of device metrics |
| `global/limit_ad_tracking = 1` | Disable advertising tracking ID |
| `global/amazon:interest_based_ads = 0` | Disable interest-based ad profiling |
| `global/amazon:sidewalk_enabled = 0` | Disable Amazon Sidewalk mesh network |
| `secure/usage_stats = 0` | Disable usage statistics |
| `global/amazon:data_monitoring_consent = 0` | Revoke data monitoring consent |
| `global/amazon:acr_enabled = 0` | Disable ACR (Automatic Content Recognition) |

### Services layer (20 packages)

Includes: `com.amazon.device.metrics`, `com.amazon.tv.acr`, `com.amazon.hybridadidservice`, `com.amazon.sneakpeek`, `com.amazon.whisperlink.core.android`, `com.amazon.ftvads.deeplinking`, and 14 others.

---

## Launcher Swap

The launcher workflow runs four verified steps:

1. Install the replacement launcher APK (skipped if already installed)
2. Set it as the default HOME activity via `cmd package set-home-activity`
3. Verify the HOME activity resolved to the new launcher
4. Disable the Amazon launcher so it cannot reassert itself

On devices with recent security patches (December 2025+), step 4 will encounter a SecurityException — the Amazon launcher is marked as a protected package. Steps 1–3 still succeed. The warning is shown in both TUI and CLI output.

To undo: `firestrip launcher restore --apply` (or the TUI Restore button) re-enables the Amazon launcher and removes the HOME preference.

**Built-in launcher definitions:**

| Launcher | Package | Type |
|---|---|---|
| Wolf Launcher | `eu.wolfgangstudios.launcher` | Polished, TMDB metadata, no ads |
| FLauncher | `me.efesser.flauncher` | FOSS, minimal, remote-friendly |
| Sideload Launcher | `com.riverrock.sideload` | Lightweight, shows sideloaded apps |

Any launcher already installed on the device (detected via HOME-intent query) is also listed automatically, tagged `[on device]`.

---

## Backup & Restore

Before any destructive operation, firestrip can snapshot the full device state to a JSON file:

```
~/.local/share/firestrip/backups/<timestamp>_<model>.json
```

The backup contains:
- Full list of all installed packages at time of backup
- All packages disabled during the session
- Current values of all telemetry and settings-tweak keys
- The default launcher package at time of backup

Restore re-enables every package that was disabled and optionally restores the launcher. Supports dry-run preview before applying.

---

## Device Settings Tweaks

The Settings screen applies five quality-of-life overrides:

| Setting | Value | Effect |
|---|---|---|
| `system/screen_brightness_mode` | `0` | Manual brightness (disable auto) |
| `global/transition_animation_scale` | `0.5` | Halve UI transition speed |
| `global/window_animation_scale` | `0.5` | Halve window animation speed |
| `global/animator_duration_scale` | `0.5` | Halve animator duration |
| `global/stay_on_while_plugged_in` | `3` | Keep screen on while charging |

---

## Supported Devices

| Device | Model | Status |
|---|---|---|
| **Fire TV Box (4K)** | `AFTBOXE1` | ✅ Primary reference device, fully tested |
| Fire TV Stick (3rd Gen) | `AFTE` | ⚠️ Profile present, community tested |
| Fire TV Stick 4K | `AFTMM` | ⚠️ Profile present, community tested |
| Fire TV Stick 4K Max | `AFTKA` | ⚠️ Profile present, community tested |
| Fire TV Stick Lite | `AFTS` | ⚠️ Profile present, community tested |
| Fire TV Stick (2nd Gen) | `AFTT` | ⚠️ Profile present, community tested |
| Fire TV Cube (1st Gen) | `AFTR` | ⚠️ Profile present, community tested |
| Fire TV Cube (2nd Gen) | `AFTRS` | ⚠️ Profile present, community tested |

The `AFTBOXE1` (codename `juliana`, MStar M7632, Android 9, FireOS `PS7712.5370N`) is the primary development and test device. All package lists, telemetry constants, and test fixtures are sourced from real hardware. Unknown models fall back to the common package database with a warning.

> **Fire TV Box (`AFTBOXE1`) users:** firestrip never touches the live TV tuner stack (`com.amazon.tv.channelscan`, `com.amazon.tv.livetv`, `com.amazon.tv.conditionalaccess`, `com.mediatek.tvinput`). These are hardcoded in `NEVER_TOUCH`.

---

## Safety Model

firestrip is designed so that normal use cannot brick your device:

- **Dry-run by default** — no action is taken until you pass `--apply` or confirm in the TUI
- **Confirmation gate** — the TUI shows a full list of planned changes in a modal before executing
- **Disable, don't uninstall** — `pm disable-user --user 0` keeps the APK on disk; `pm enable --user 0` undoes it instantly
- **`NEVER_TOUCH` enforcement** — system-critical packages are stripped from all tier lists at load time and cannot be selected under any circumstances
- **Per-device profiles** — package lists are model-specific; there is no cross-model guessing
- **Automatic backup** — the TUI backs up state before applying debloat operations
- **Restore in one step** — any backup can be applied to re-enable everything firestrip disabled

---

## MX Linux / Systemdless Notes

firestrip treats MX Linux and other non-systemd distributions as first-class:

- Zero `systemd` dependencies anywhere in the codebase
- ADB server lifecycle managed via subprocess (`adb start-server` / `adb kill-server`)
- Automatic reconnect when the Fire TV wakes from sleep
- udev rule helper (`firestrip setup-udev`) writes `/etc/udev/rules.d/51-firestrip-android.rules` and reloads rules — no daemon needed after that

---

## Contributing

Contributions are welcome — especially:

- **Package list updates** for new FireOS versions or devices
- **New device profiles** (Fire TV Cube 3rd gen, Fire TV pendant)
- **Launcher entries** in `firestrip/data/launchers/launchers.toml`
- **Testing on non-Box hardware** with real package lists

See [DESIGN.md](DESIGN.md) for the full architecture, data model, and developer reference.
