LineageOS is a free, community built, aftermarket firmware distribution of Android, which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for LineageOS is available in the LineageOS GitHub repo. And if you would like to contribute to LineageOS, please visit Gerrit Code Review.
MUST-READ BACKGROUND - Android 13 and the two approaches:
As some of you already know, due to various reasons, @phhusson , who kickstarted the GSI trend and committed to it over the years, is backing out from future development - there won't be any AOSP 13+ builds or patches directly from him. He did most of the heavylifting for fixing bugs and implementing features, and selflessly supported more than his AOSP GSIs and more than devices he own. For the situation of GSIs today, we owe him a big thank-you.
Earlier, inspired by @PeterCxy , I took the "light" approach, which starts over from AOSP's generic gsi_* target and adds the minimum amount of fixes needed for my own devices, intentionally leaving many legacy devices behind. For more details about it, visit its own thread.
Meanwhile, a number of existing builders incl. myself have formed the TrebleDroid organization, with PHH himself helping us in technical issues. TD will forward-port PHH's final patches (v415) onto Android 13 and attempt to fix new issues. This is still a new and ongoing process, but if done right, will have compatibility and feature-completion on par with past PHH-based GSIs. This thread contains LOS builds based on TrebleDroid's collective work, which supposedly suits legacy devices, Samsung, etc. better than "light".
No flashing instructions will be offered. If you're here in this forum, you should know what you're doing.
No guarantees that everything would work. This is a GSI, bugs are bound to happen.
MUST-READ - reporting bugs:
If you want to report a bug, then you MUST try reproducing on an AOSP reference build of around the same date from TrebleDroid, and ONLY proceed to report here when it's specific to this GSI. This filters out bugs common to all TD-based GSIs, which you should still let me know, but it might not be mine to fix. I might silently ignore your report if you skip this.

Stuff on GitHub (builders-only):
Most things should be self-explanatory. Not the cleanest code, but should help if you need some clues.
- lineage_build_unified - my unified script for building
- lineage_patches_unified - my unified patches for building
- The LineageOS team
- @phhusson - shaped the treble community, and still takes care of TrebleDroid at a higher level
- @PeterCxy - coded critical fixes such as sysbta
