LineageOS 24.0

Installing LineageOS is now more accessible with browser-based flashing tools.

LineageOS has released version 24.0, based on Android 17, ahead of its 10th anniversary on December 24, 2026. This update merges security patches from August 2025 through October 2026 for versions 18.1 to 24.0, and through November 2025 for legacy branches 15.1 to 17.1. Core applications have been updated, many adopting Material Design 3, and new features include a Canvas image editor, revamped Catapult launcher, and improved Twelve music app. Jelly browser now supports PWA-like apps, and the Updater app streamlines installations with default streaming. Notably, LineageOS introduces browser-based WebUSB flash tools for ADB Fastboot, Amlogic, and Samsung Odin protocols, simplifying installation. CI/CD improvements enhance testing and pre-review processes. An accessibility audit was completed, aiming to improve LineageOS's usability for all. The release also marks a shift, with new kernel versions required for LineageOS 23.2 and 24.0, while older kernel versions (4.4 and 4.9) will only be supported on LineageOS 22.2.

The introduction of WebUSB flash tools signifies a strategic move to democratize custom ROM installation. By abstracting away the need for separate desktop utilities, LineageOS lowers the barrier to entry for users less familiar with command-line interfaces or traditional flashing methods. This approach leverages modern browser capabilities to provide a more integrated and user-friendly experience, potentially increasing adoption rates for custom ROMs.

This release also highlights the evolving maintenance challenges of open-source projects. The decision to deprecate older kernel versions for newer LineageOS branches illustrates the increasing difficulty in backporting complex platform commits and maintaining compatibility with the latest Android versions. This signals a trend toward more stringent hardware and software requirements for future custom ROM development, potentially impacting the longevity of support for older devices.
