Here’s my build of LineageOS 22.1 for Raspberry Pi 4 Model B, Pi 400, and Compute Module 4. It is unofficial and unsupported by the LineageOS team. It’s for advanced users only. Pi 4 model with at least 2GB of RAM is required to run this build.

Important! Raspberry Pi hardware specific implementation in this build is based on source code released on my Raspberry Vanilla project but this build offers various additional features and enhancements.

You may use this build freely in personal/educational/etc use. Commercial use is not allowed with this build! You can contact me by email to discuss creating customized Android builds for commercial purposes.
