.These instructions will hopefully assist you to start with a stock OnePlus Nord N200, unlock the bootloader (if necessary), and then download
the required tools as well as the very latest source code for LineageOS (based on Google’s Android operating system) for your device. Using these, you can build both
a LineageOS installation zip and a LineageOS Recovery image and install them on your device.
It is difficult to say how much experience is necessary to follow these instructions. While this guide is certainly not for the extremely uninitiated,
these steps shouldn’t require a PhD in software development either. Some readers will have no difficulty and breeze through the steps easily.
Others may struggle over the most basic operation. Because people’s experiences, backgrounds, and intuitions differ, it may be a good idea to read through
just to ascertain whether you feel comfortable or are getting over your head.
Remember, you assume all risk of trying this, but you will reap the rewards! It’s pretty satisfying to boot into a fresh operating system you baked at home :).
And once you’re an Android-building ninja, there will be no more need to wait for “nightly” builds from anyone. You will have at your fingertips the skills to
build a full operating system from code and install it to a running device, whenever you want. Where you go from there– maybe you’ll add a feature, fix a bug, add a translation,
or use what you’ve learned to build a new app or port to a new device– or maybe you’ll never build again– it’s all really up to you.
ccache
cd
, which stands for “change directory”, the concept of directory hierarchies, and that in Linux they are separated by /
, etc.Let’s begin!
If you haven’t previously installed adb
and fastboot
, you can download them from Google.
Extract it running:
unzip platform-tools-latest-linux.zip -d ~
Now you have to add adb
and fastboot
to your PATH. Open ~/.profile
and add the following:
# add Android SDK platform tools to path
if [ -d "$HOME/platform-tools" ] ; then
PATH="$HOME/platform-tools:$PATH"
fi
Then, run source ~/.profile
to update your environment.
Several packages are needed to build LineageOS. You can install these using your distribution’s package manager.
apt-get install
To build LineageOS, you’ll need:
bc bison build-essential ccache curl flex g++-multilib gcc-multilib git gnupg gperf imagemagick
lib32ncurses5-dev lib32readline-dev lib32z1-dev liblz4-tool libncurses5 libncurses5-dev
libsdl1.2-dev libssl-dev libxml2 libxml2-utils lzop pngcrush rsync
schedtool squashfs-tools xsltproc
zip zlib1g-dev
For Ubuntu versions older than 20.04 (focal), install also:
libwxgtk3.0-dev
While for Ubuntu versions older than 16.04 (xenial), install:
libwxgtk2.8-dev
Different versions of LineageOS require different JDK (Java Development Kit) versions.
openjdk-8-jdk
)openjdk-7-jdk
)** Ubuntu 16.04 and newer do not have OpenJDK 1.7 in the standard package repositories. See the Ask Ubuntu question “How do I install openjdk 7 on Ubuntu 16.04 or higher?”. Note that the suggestion to use PPA openjdk-r is outdated (the PPA has never updated their offering of openjdk-7-jdk, so it lacks security fixes); skip that answer even if it is the most upvoted.
You’ll need to set up some directories in your build environment.
To create them:
mkdir -p ~/bin
mkdir -p ~/android/lineage
The ~/bin
directory will contain the git-repo tool (commonly named “repo”) and the ~/android/lineage
directory will contain the source code of LineageOS.
repo
commandEnter the following to download the repo
binary and make it executable (runnable):
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
~/bin
directory in your path of executionIn recent versions of Ubuntu, ~/bin
should already be in your PATH. You can check this by opening ~/.profile
with a text editor and verifying the following code exists (add it if it is missing):
# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
fi
Then, run source ~/.profile
to update your environment.
Given that repo
requires you to identify yourself to sync Android, run the following commands to configure your git
identity:
git config --global user.email "[email protected]"
git config --global user.name "Your Name"
Make use of ccache
if you want to speed up subsequent builds by running:
export USE_CCACHE=1
export CCACHE_EXEC=/usr/bin/ccache
and adding that line to your ~/.bashrc
file. Then, specify the maximum amount of disk space you want ccache
to use by typing this:
ccache -M 50G
where 50G
corresponds to 50GB of cache. This needs to be run once. Anywhere from 25GB-100GB will result in very noticeably increased build speeds
(for instance, a typical 1hr build time can be reduced to 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan to build
for several devices that do not share the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this
into consideration.
You can also enable the optional ccache
compression. While this may involve a slight performance slowdown, it increases the number of files that fit in the cache. To enable it, run:
ccache -o compression=true
ccache
size can be lower (aim for approximately 20GB for one device).The following branches are officially supported for the OnePlus Nord N200:
Enter the following to initialize the repository:
cd ~/android/lineage
repo init -u https://github.com/LineageOS/android.git -b lineage-19.1
To start the download of the source code to your computer, type the following:
repo sync
The LineageOS manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. don’t add any options to sync).
For reference, our default values are -j 4
and -c
. The -j 4
part implies be four simultaneous threads/connections. If you experience
problems syncing, you can lower this to -j 3
or -j 2
. On the other hand, -c
makes repo to pull in only the current branch instead of all branches that are available on GitHub.
repo sync
command is used to update the latest source code from LineageOS and Google. Remember it, as you may want torepo sync
may wipe them away!After the source downloads, ensure you’re in the root of the source code (cd ~/android/lineage
), then type:
source build/envsetup.sh
breakfast dre
This will download your device’s device specific configuration and
kernel.
breakfast
Now ensure your OnePlus Nord N200 is connected to your computer via the USB cable, with ADB and root enabled, and that you are in the
~/android/lineage/device/oneplus/dre
folder. Then run the extract-files.sh
script:
./extract-files.sh
The blobs should be pulled into the ~/android/lineage/vendor/oneplus
folder. If you see “command not found” errors, adb
may
need to be placed in ~/bin
.
Time to start building! Now, type:
croot
brunch dre
The build should begin.
Assuming the build completed without errors (it will be obvious when it finishes), type the following in the terminal window the build ran in:
cd $OUT
There you’ll find all the files that were created. The two files of more interest are:
boot.img
, which is the LineageOS boot image, and contains the recovery-ramdisk.
lineage-19.1-20220726-UNOFFICIAL-dre.zip
, which is the LineageOS
installer package.
You’ve done it! Welcome to the elite club of self-builders. You’ve built your operating system from scratch, from the ground up. You are the master/mistress of your domain… and
hopefully you’ve learned a bit on the way and had some fun too.
