How to Install:
• Wipe data, dalvik-cache and cache.
• Flash Lineage zip and then dm-verity disabler.
• MAKE SURE YOU ARE INSTALLING LINEAGE OVER FULLY STOCK ANDROID 10 FIRMWARE.

If you don't follow these instructions, please don't expect support here.

We also don't support 3rd party addons (Magisk/XPosed/Dolby/Viper/etc.), so if you have any random reboots or problems caused by using these.


What won't work? :
• IMS services (VoLTE, VoWiFi, etc). Samsung has their own proprietary implementation. It is not really possible to easily port that to LineageOS.
• Rounded corners weren't implemented so use the following provided overlay.zip u til I update the rom.


Notes:
• Lineage OS builds will not pass CTS/SafetyNet -- due to the AVB flag's "red" status.
• Lineage OS builds requires official stock unmodded Android 10 OneUI2.5 firmware installed.
• If you want to use encryption then use lineage recovery provided below.

    I tested this Custom ROM, and I gotta say, that's probably the best one I used yet. Battery life as well as performace is like night and day compared to OneUI.
    That being said, I hope when 18.1 becomes stable we'll be able to get it as one package for M21 too.
