LineageOS for the Echo Show 8 (2nd Gen), Kiosk Satellite Edition 2026.11.1

The first release for the Echo Show 8 (2nd gen) from 2021. It is jxlarrea's own port: LineageOS 18.1 with a kernel built from Amazon's source release in android_kernel_amazon_mt8183, the hardware drivers that are already on the Show and the Kiosk Satellite Edition layer on top. It requires Kiosk Satellite 2026.11.16 or newer.

What's included

• A raw microphone for Kiosk Satellite. Kiosk Satellite hears the microphones as captured, with no echo cancelling, noise suppression or gain control from Amazon's audio HAL or the image, so its own echo canceller sees the speaker's echo at a fixed delay. Kiosk Satellite 2026.11.16 and newer add the Show's base gain, the same as on the Echo Show 8 (1st gen).
• Amazon's wake word engine with files you install. The image includes none of Amazon's libraries or models. If you put Pryon's files in /data/pryon yourself, pryond runs them for Kiosk Satellite and "stop" works without the wake word. See Amazon's wake word engine.
• Kiosk Satellite on first boot. Once the Show is on Wi-Fi, ks-install downloads the latest Kiosk Satellite, installs it, gives it every permission it needs and makes it the device owner. Kiosk Satellite then makes itself the home screen and reports the Show's real Wi-Fi MAC address to Home Assistant.
• Nothing to tap through. There is no setup wizard and no lock screen. adb works over USB from the first boot, so a computer only has to be allowed on the screen once. Allowed computers do not expire. Android's screen timeout is set to never, so only Kiosk Satellite dims the screen or turns it off.
• Set up from adb. echo_service joins Wi-Fi, sets the time and time zone from your computer and changes the Show's settings without touching the screen.
• Privacy and the screen on separate presses. Press the button briefly to turn privacy on or off. Hold it for 3 seconds to turn the screen on or off.
• Double tap to wake. Double tap the screen while it is off to turn it back on. A single tap leaves it off.
• Volume that fits the speaker. The Show's amplifier is far stronger than its speakers need, so the image holds the speaker 6 dB under the amplifier's full output. A fresh install starts at 60% master volume, the recommended level.
• Bluetooth both ways. echo_service bt pair lets phones play to the Show as a Bluetooth speaker. echo_service bt connect [name] plays the Show's audio through Bluetooth headphones or a speaker instead. Kiosk Satellite's Bluetooth proxy for Home Assistant works in both.
• Steady Wi-Fi. Android keeps the access point it joined instead of moving between mesh nodes. It picks an access point by signal strength, preferring 5 GHz. The image also connects to a network in WPA2/WPA3 transition mode with WPA2, including one that also offers WPA2 with SHA256.
• System updates. EchoService finds, downloads and installs new releases of this image. Kiosk Satellite shows them in its remote admin and as a Firmware update in Home Assistant.
• The Kiosk Satellite boot animation and a plain wallpaper. The bars of the Kiosk Satellite mark bounce while Android boots, then the house fades in around them. A fresh install gets a plain #444444 wallpaper.
• More free memory. With Kiosk Satellite on screen, about 1 GB of the Show's 2 GB stays available. The image leaves out telephony, the LineageOS updater and the apps a kiosk does not use.
• The vendor, recovery and bootloader partitions stay as the unlock left them. An install or an update only writes the system and boot partitions.

Installing

Follow the Echo Show 8 (2nd gen) guide. The install erases the Show.

Requirements

The Show needs R0rt1z2's saiyaku unlock with TWRP 3.7.0_9-0. See Unlocking, which also covers getting the Show on a Fire OS version saiyaku supports. The image only writes the system and boot partitions and keeps the Show's hardware drivers where they already are. It is tested on a Show that was on Fire OS 7575.1 (PS75751/7809) when it was unlocked.

Kiosk Satellite needs to be 2026.11.16 or newer, the first version with the Show's base gain.
