This tutorial will show you how to install Lineage OS custom ROM on an Android phone.

What is Lineage OS?

If you have heard about custom ROMs, then I bet you have heard these 2 names – CyanogenMod and Lineage OS.

Although CyanogenMod discontinued in 2016, it was the most popular custom ROM in the world. After its discontinuation, the CyanogenMod developers forked and re-branded the cyanogen code into a new project called Lineage OS.

Now, Lineage is the most popular custom ROM in the world. It’s a free and open-source operating system for various devices based on the Android mobile platform.

One of the main reasons why people turn to custom ROM is that their phone manufacturers stop providing updates. Lineage OS extends the functionality and lifespan of mobile devices by providing users with the latest Android experience on their old devices.

Many other custom ROM devs use Lineage as a base for their ROM. It also has the biggest open source community in the world of custom ROMs.

Lineage OS Compatible Devices

The most popular custom ROM supports almost every Android phone officially or unofficially. As of writing this post, Lineage OS supports 25+ vendors and 150+ devices officially.

Here’s a list of all the vendors Lineage OS supports officially:

Note: The lineage OS team regularly updates the list of supported devices, so always check their official site for updated information. 

  • Asus
  • BQ
  • Essential
  • Fairphone
  • FxTec

  • Nubia
  • OnePlus
  • OPPO
  • Razer
  • Realme
  • Samsung
  • Sony
  • Wileyfox
  • Wingtech
  • Xiaomi
  • Yandex
  • Zuk

The above mentioned are the list of device manufacturers, if you want to know that your particular device supports this ROM, then head over to the Lineage OS official website.

Lineage supports almost every android phone out there. If there is no official build of Lineage OS for your phone, then you can try the following:

1. Go to XDA developers and find an unofficial port of Lineage for your device. There’s a high chance you’ll find an unofficial port for your device.

2. Wait for someone to create/port a build of Lineage OS for your phone. You can also build one yourself if you have enough knowledge. Lineage also offers an easy to follow build guide.

3. If you have no luck with the above 2, then navigate to my Best custom Roms for android post and pick another custom ROM for your device.

Features of Lineage OS

Unlike other custom ROMs, Lineage OS doesn’t provide you with loads of customizations. They tend to keep things simple and stable as possible.

Here’s the list of some additional features and customizations Lineage OS provides:

  • No Bloatware
  • Native theme support
  • LiveDisplay
  • Lock screen customization
  • Weather providers
  • System Profiles
  • ADB root
  • Expanded Desktop
  • LineageOS’s Privacy Guard
  • CPU overclocking
  • Option for root access
  • And some other enhancements.

Now, you’ll see play store and other Google apps in your app drawer.

Flash Magisk (Optional)

In Lineage OS, you can enable/disable root access via developer options without the need for flashing Magisk.

However, there are several benefits of flashing Magisk App to gain root access. Using Magisk you can hide root access from other apps and services.

This way you can run apps that doesn’t run on rooted devices.

Before you make up your mind on rooting your device, I recommend you to have a look at my rooting android phone post, in which I have mentioned the advantages and disadvantages of rooting an Android phone.

Steps to flash Magisk:

1. Change the extension of the Magisk file from “.apk” to “.zip”. This will make it flashable. 

2. Copy Magisk App (.zip file) to the phone.

3. Reboot to recovery.

4. Select install.

5. Choose the Magisk zip file.

6. Swipe to confirm flash.

7. Wait for the process to complete then Wipe Cache/Dalvik.

9. If it says to download and install the full Magisk package, then go ahead and do that.

10. Once it’s done, you can click on the “Check SafetyNet” option in the Magisk app.
