Since September 2018 until May 2020 developers Ivan Meler based on Android 9 Pie builds LineageOS 16.0 for Samsung Galaxy S7 - “herolte” and refers to the source code and local_manifests as well as roomservice.
Device codename “herolte” confirmed by:
adb shell getprop ro.product.device
herolte
The LOS 16.0 builds work well. I’ve installed them several times. Is it not possible to build a /e/ OS 9-pie ROM based on these findings?
