# Installing LineageOS on Amazon Echo Show: Unlocking the Bootloader and Installing Android
XDA Developers developers have published a guide to gaining root access on Amazon Echo Show models. The process allows replacing Fire OS with LineageOS 18.1 (Android 11), turning the device into a full-fledged Android tablet without ties to the Amazon ecosystem.
Supported models: Echo Show 5 (1st generation, 2019), Echo Show 5 (2nd generation, 2021), and Echo Show 8 (1st generation, 2019). After modification, the display can serve as a hub for Home Assistant, a media player, or a versatile tablet with access to Google Play.
Technical Details of Exploiting Vulnerabilities
The devices are built on MediaTek chips, allowing exploitation of known BootROM vulnerabilities. The main stage is gaining access to the preloader mode to attack the bootloader.
Developers have released the amonet fastbrick tool, which simplifies unlocking. The process includes:
- Connecting the device to a PC via USB.
- Running the utility for fastboot unlocking.
- Installing TWRP (Team Win Recovery Project).
- Flashing LineageOS via recovery.
# Example commands for installing TWRP

Installing Custom Firmware and Post-Modification Steps
After unlocking the bootloader:
- Boot into TWRP.
- Flash LineageOS 18.1 (ROM + GApps optional).
- Wipe cache and dalvik.
- Reboot to system.
The resulting build eliminates dependency on Amazon services. The display supports sideloading APKs, VNC servers, and integration with open-source smart home ecosystems.
# Installing LineageOS via ADB sideload in TWRP

Risks, Limitations, and Prospects
The method is not universal: future Amazon OTA updates may patch BootROM vulnerabilities. It's recommended to disable auto-updates.
- Pros: Complete freedom from vendor lock-in, support for FOSS apps.
- Cons: Loss of Amazon's proprietary features (Alexa), risk of bricking, no official support.
- Alternatives: The method doesn't work for newer models (3rd generation+) due to enhanced protection.
Users note motivation from aggressive advertising on stock devices—full-screen banners reduce usability.
Key Points
- Support for three Echo Show models on MediaTek with bootloader unlocking via amonet fastbrick.
- Installing LineageOS 18.1 + TWRP to turn it into an Android tablet without Amazon services.
- Exploiting BootROM vulnerabilities; risk of bricking and patches in future updates.
- Ideal for Home Assistant, sideloading APKs, and open-source smart home.
- Recommended for mid/senior developers with custom ROM experience.
