LineageOS for the Echo Dot (2nd Gen), Kiosk Satellite Edition 2026.11.4

This release cuts down on writes to the Dot's storage: the nightly storage trim now runs and an error report that Android wrote every 30 minutes is gone. Nothing else changes on the Dot.

Changes

• The nightly storage trim runs. Android's storage maintenance, which trims /data and /cache, waited for the device to be idle and charging. An Echo is never idle that way and most report no charging battery, so the trim never ran. It now runs once a day at 3 AM. Regular trims tell the eMMC which blocks are free, which helps it spread wear.
• No more error report every 30 minutes. The kernel has no per-app network statistics, so Android's statistics poll failed every 30 minutes and on every network change and wrote an error report to storage each time. Android now reports empty statistics there. Data usage numbers were already empty on this kernel.
• New recommended volumes in the guide. With Kiosk Satellite's equalizer, which is on by default on the Dot, the guide recommends master volume 100%, Kiosk Satellite's assistant and intercom volumes at 100% and its media player volume at 85%. It recommended master volume 75% before.
• The Dot's layer is shared with the Echo Dot (3rd gen). BiscuitService, the ring daemon, the light sensor HAL, ks-install and the updater moved to a layer both Echo Dots build from. Nothing changes on the Dot.

Updating

Install it from the Dot's Firmware entity in Home Assistant or from Kiosk Satellite's remote admin. BiscuitService installs it into both slots and restarts the Dot twice. Kiosk Satellite and its settings stay. Keep the Dot on its own power adapter, not a USB hub, or TWRP may not start. If your Dot cannot get online yet, install this release by hand from TWRP with the steps in the Echo Dot guide, leaving out twrp wipe data.

Requirements

The Dot needs amonet v2.0.0 or v2.0.1 with TWRP 3.7.0_9-0. See Unlocking.

Kiosk Satellite needs to be 2026.11.1 or newer. Its echo canceller is built for the raw microphone the image gives it since 2026.10.18, so update Kiosk Satellite on the Dot too. Amazon's wake word engine through pryond requires Kiosk Satellite 2026.11.14 or newer.
