While the LineageOS ROM was under development for some time for the Xiaomi Mi5s, now it’s available officially from the LineageOS website itself. That also means that the build has cleared the alpha stage, or even experimental stage, as a nightly is what that has made to downloads section.
Powered by powerful Qualcomm 821 processor, the Mi5s came with MIUI8 preinstalled, based on Android Marshmallow. No offence to Xiaomi, and their beautiful UI, but stock UI remain unbeatable even today — which is why many Xiaomi Mi5s users could hop to LineageOS to get the stock UI, that too on latest Android version which LineageOS is based on.
With LineageOS 14.1, you will not only get tons of customization options but performance also is great.
To install LineageOS, you will of course need to go through the whole waiting process of unlocking your device, after receiving Xiaomi’s permission. Once that is over and done with, you can flash TWRP custom recovery using this guide and then flash the ROM.
