Building Android LineageOS: A Step-By-Step Guide

Android LineageOS on ODROID

This guide will show you how to download and compile the Android kernel for ODROID-XU3/XU4. If you have not built Android on your desktop yet, please read Google’s official build environment setup guide at Carefully review this before you proceed, or you may have unexpected errors and will need to read through long and complicated build logs to find the problem.

We used Ubuntu 14.04 64bit with 8GB of RAM since other newer versions of Ubuntu have had some issues while building the Android OS. If you want to build the full Android source tree, don't download and build the kernel source separately. A separated Kernel build might break the Android build process. Install the openjdk-8-jdk If your build environment is Ubuntu 14.04 or 12.40, enter the following:

$ sudo add-apt-repository ppa:openjdk-r/ppa
$ sudo apt-get update
And you can install the openjdk-8-jdk using apt:
$ sudo apt-get install openjdk-8-jdk
$ java -version
openjdk version "1.8.0_131"
OpenJDK Runtime Environment (build 1.8.0_131-8u131-b11-2ubuntu1.16.04.3-b11)
OpenJDK 64-Bit Server VM (build 25.131-b11, mixed mode)
If you have more the one Java versions installed, you can change the Java version:
$ sudo update-alternatives --config java
$ sudo update alternatives --config javac
Please note that we distribute the Linux kernel in different branches for Android and other Linux distributions.

Android platform and kernel

The repository is available for download at Android’s full downloaded source code size is around 70GB, so make sure to prepare enough space before building the Android platform:

$ mkdir
$ cd
$ repo init -u -b cm-14.1_5422
$ repo sync

Opengapps (optional)

To include Opengapps to the target image, create the “opengapps.xml” file in /.repo/local_manifests folder with this content:

<!--?xml version="1.0" encoding="UTF-8"?-->< manifest>
< remote name="opengapps" fetch="" />
< project path="vendor/opengapps/build" name="aosp_build" revision="master" remote="opengapps" />
< project path="vendor/opengapps/sources/all" name="all" clone-depth="1" revision="master" remote="opengapps" />
< project path="vendor/opengapps/sources/arm" clone-depth="1" revision="master" remote="opengapps" />
</ manifest>
Then, run the following commands:
$ cd
$ repo sync --force-sync
Before compiling, you must configure the ODROID-XU3 with the following commands.
$ ./ odroidxu3
Once you complete the long build process, the img files can be found in the “/tmp/odroidxu3/” directory. To use ADB over a TCP/IP connection, please refer to

Installation for ODROID-XU3/XU3-Lite

There are different instructions for installing a Linux kernel image for Android and Linux. Since Android loads both from a kernel partition, we have to use fastboot to install into the dedicated partition. Before beginning, please refer to the partition table at By contrast, Linux boots by the instructions described in boot.ini on the 1st FAT partition.

First, install the kernel image zImage-dtb, onto the boot board:

$ sudo fastboot flash kernel <path/of/your/zImage-dtb>
Next, install the android platform files system.img, userdata.img, and cache.img:
$ sudo fastboot flash system <path/of/your/system.img> $ sudo fastboot flash userdata <path/of/your/userdata.img> $ sudo fastboot flash cache <path/of/your/cache.img>
Finally, initialize the FAT partition:
$ sudo fastboot erase fat

Installation for ODROID-XU4

You can avoid using fastboot on an ODROID-XU4, because it doesn't have an USB OTG port. First, setup an ADB connection or copy an image to the FAT partition:

$ adb push xxxx.img /sdcard/
$ adb reboot
View the U-Boot logs by connecting to the ODROID-XU4 with a USB-UART kit:
