Don’t get us wrong here, it was more refined than the horrendous UI that was Touchwiz but it was still Samsung’s Android skin. That meant it quickly degraded over time. Samsung knew this would happen so they designed an all new UI called the ONE UI for their phones. But that too is Samsung’s Android. What if you want a stock Android experience that has no DNA of Samsung. Well now you can. XDA developers have successfully ported unofficial LineageOS 16 for Galaxy S9 and S9+ (only Exynos based models) So lets get your phone up and running with LineageOS 16..
Warning
Rooting and unlocking the bootloader are modifications that the device manufacturer didn’t intended. And as such these carry certain risks which involve unstable operation, partially working software or in some extreme cases the device getting bricked. So root your device at your own risk.
Prerequisites
Charge your phone up-to 70% before proceeding any further Root access on your device. A custom recovery like TWRP. Download the official TWRP for Galaxy S9 here and for the Galaxy S9+ here LineageOS 16 for the Galaxy S9 and Galaxy S9+
Step 1: Rooting Your Phone and Installing TWRP
The first step in getting LineageOS 16 for Galaxy S9 and the S9+ is to root your device and install a custom recovery. We prefer TWRP when it comes to custom recoveries. To root your device and install TWRP, follow our guide here. It was originally written for the Galaxy Note 9. The process is exactly same for Galaxy S9 series. Just remember to choose the TWRP image file that is specifically for your device. Download the TWRP images from the links given above and follow the guide we just linked.
