Download/Install Lineage OS 18 for Xiaomi Mi Max/Prime (Android 11)

Xiaomi Mi Max/Prime was launched way back in 2016 and was running on the Android 6.0 Marshmallow out of the box. Later the device was upgraded to Android 7.0 Nougat officially. However, the device isn’t supporting the official Android 11 update, here we’ll be sharing the full depth guide on how to download and install the unofficial Lineage OS 18 [Alpha, Permissive] for Xiaomi Mi Max/Prime based on Android 11.

So, if you’re one of the Xiaomi Mi Max/Prime (Codenamed – hydrogen/helium) device users and want to use the newly launched Android 11 OS right away on your handset, this guide is for you. Needless to say that due to the Android’s open-source nature, most of the third-party ROM developers and even the Android users are always looking for unlimited possibilities to easily flash the custom firmware. Lineage OS is no exception here and you’ll be glad to hear that you’ll be able to customize the whole UI, lock screen, icons, fonts, themes, notification bar, navigation bar, launcher, etc apart from using the rooted apps (You can also install Root after flashing the Lineage OS on your device).

It’s also worth mentioning that you have to unlock the device bootloader first as all the Android devices do come with a locked bootloader from its manufacturer out of the box. Once you unlocked your device bootloader, you’ll be free to customize, install custom firmware, custom modules, enable root access, and more on your Android device without any limitation. Whereas Google has also uploaded the Android 11 Source Code to AOSP so that the custom firmware developers can easily build their third-party ROM for compatible devices.

Lineage OS 18 Features

LineageOS is a free, community-built, aftermarket firmware distribution of Android 10, which is designed to increase performance and reliability over stock Android for your device. LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community.

It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restores the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

So, we do recommend not to flash the ROM on your primary device.
