The YIOS 5.1.1 custom ROM for the Redmi 2 has been developed by Aromer. The ROM is actually just an Unofficial CM 12.1 port, as YIOS simply means ‘unofficial CyanogenMod’. So this ROM is basically just plain vanilla CM 12.1 with no additional features or tweaks. The ROM is currently stable around but there are a few minor bugs and issues that need to be fixed.
However, even now you could use this ROM as a daily driver if you can live with the minor bugs and issues. Feedback on the ROM from users is quite positive so far, so this is one of the best ROMs currently available for the Redmi 2 if you wish to try out the latest Android 5.1 Lollipop version on your device.
