Read the whole OP! Be respectful to each other and don't ask for ETAs, it's considered as being rude!

Syberia Project (aka Syberia OS) is a custom ROM for MI 9 (cepheus) that implements various features. This project was designed by our "Syberia Team" from scratch based on AOSP source code with some CAF fixes and improvements. Our team: @DennySPB, @blinoff82, @alexxxdev. Also many thanks to our designer @rlshukhov for logos, wallpapers and bootanimation.

If you like our work you can buy us a cup of coffee or a glass of beer :p
