LineageOS is a free, community built, aftermarket firmware distribution of Android 9.0 (Pie), 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. You will need to provide your own Google Applications package (gapps). 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 our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

LineageOS 16.0 Install Guide

Note: LineageOS for Galaxy S4 Active is provided with no warranty. You are installing this software at your own risk. You may be violating your warranty.

Download LineageOS and gapps zips and put in /sdcard

Latest build: http://www.mediafire.com/file/nxgfl6b9z545ql2/lineage-16.0-20190723-UNOFFICIAL-jactivelte.zip/file

Builds Archive

Google Apps (MindTheGapps is recommended. Pick ARM, not ARM64)

Before you install LineageOS: Preparation

(Optional. If you want to start fresh, these can be skipped)

Install Easy Backup & Restore from Market, run it and backup your stuff.

Boot into recovery. Make a full backup. You will need this backup later if you decide to go back to your previous ROM and data.

I suggest using this TWRP: http://www.mediafire.com/file/18vo85kssa8caqq/twrp-3.2.3-0-jactivelte.img.tar.md5/file

WARNING: Many apps will Force Close crash if you restore data from a previous ROM.

Install

Boot into recovery.

Wipe data and cache.

Flash lineage-16*.zip.

Flash gapps*.zip.

Reboot phone.

After you setup your Google account, reinstall Easy Backup & Restore from Market in order to restore most of your apps, call log and SMS history.

Warning: Do not restore backup data of system apps!

If you restore a bad backup with cached settings in telephony.db in data/data/com.*.*.telephony it can break MMS.

It seems that restoring backups can also break Calendar sync.

Upgrades

Upgrades from previous builds of LineageOS 16.0 are the same process as install, except you do not need to wipe anything. Contrary to popular belief, you do not need to even wipe cache and dalvik-cache when upgrading between LineageOS 16.0 versions. You only need to wipe if you are doing a major upgrade, switching to a different ROM entirely, or attempting to fix bugs caused by bad backups or corrupt app data.
