LineageOS is a free, community built, aftermarket firmware distribution of Android 12L (Sv2), 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. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

Seriously, just don't use any other recovery

- Flash the recovery from fastboot with
fastboot flash recovery recovery.img- Reboot to recovery
- Go to Advanced > Enter fastboot
- Connect your phone to your PC and enter the following command:
fastboot wipe-super super_empty.imgIf you get an error like “Unknown command” you don’t have updated platform-tools, go back to the top of the guide
- Press “Enter recovery” on your phone
- Format data with Factory reset > Format data/factory reset
- Sideload the zip file with Apply update > Apply from ADB and on your PC enter the following command:
adb sideload <zip file>- Sideload any other addon you want like Google apps (these are the recommended ones)
