10/2021: The latest option for Redmi 2 is Lineage OS 17 which is based on Android 10.
Update 12/2018: New links added of MIUI 9 of both recovery and fastboot ROM. In July 2016, MIUI released MIUI 8 for Redmi 2 and prime.
Redmi 2/ Prime users waited longer for the official Android 5 update. Redmi 2 lollipop official update arrived now. Miui team recruited some forum members to test the Android 5 build on their Redmi 2 devices.
While it’s for Redmi 2 prime, but you can still install this in 1GB variants too.
The ROM is still in beta phase so that you might run into some bugs.
While if you need screenshots, I would like to tell you that they are just similar to old MIUI builds.
