Install LineageOS 14.1 on Galaxy S8 (Exynos) – Nougat Custom ROM

Bringing AOSP Android on Samsung smartphone is much harder than other Qualcomm-based development as the OEM does not provide documentation of their chipsets. It’s pretty much hit or a missed game to work on these devices until everything works well. However Galaxy S7 got listed on the official support of LineageOS, and now it’s time for the Galaxy S8, Samsung’s early 2017’s flagship.

XDA Recognized Developer Fevax, who is also maintaining the official LineageOS 14.1 on Galaxy S7 and S7 Edge, has released an unofficial build of LineageOS for Galaxy S8. This Alpha-quality LineageOS is the first non-TouchWiz custom ROM for Galaxy S8. That’s quite an achievement: even it does have a couple of known bugs, the majority of essentials – Wifi, Bluetooth, and most sensors are working fine, only a matter of polishing until it’s finally official.

This Alpha build is based on Android 7.1.2 Nougat, and you would require a custom recovery like TWRP to flash the firmware. Just keep in mind, this ROM is only for Exynos model, as the US Galaxy S8 owners of Snapdragon-powered versions are not lucky to have it due to the factory locked bootloader.

As you continue reading below, we will guide you through an entire step-by-step tutorial with all necessary tools (download links are given below, keep reading to grab and install).

If flashing via TWRP Recovery is not a new task for you, this guide would not be much difficult. We have covered entire step-by-step tutorial so that a new user can perform the flash easily.
