At the end of 2017, team M.A.D finally fulfilled Coolpad Note 3 Lite user’s hunger for Oreo ROM. The ROM is madOS v2.1 based on Android Oreo 8.1.0. Previously on the same day, M.A.D had also released madOS for Coolpad Note 3 users, lite users were sure that they too would get a chance to taste Oreo.

madOS is based on pure A.O.S.P. with many additional customizations and MediaTek support. Since Team M.A.D don’t own Coolpad Note 3 Lite, they still managed to give a near stable build for the users. There are some major bugs that we will be hunting over a next few days.

Note: Do check the bugs listed at the end. Don’t simply flash the ROM without reading full instructions
