Installing CyanogenMod from recovery

Place the CyanogenMod .zip package, as well as any optional .zip packages, on the root of /sdcard:Note: You can copy the .zip packages to lớn your device using any method you are familiar with. The adb method is used here because it is universal across all devices và works in both Android and recovery mode. If you are in recovery mode, you may need lớn ensure /sdcard (sometimes called Internal Storage) is mounted by checking its status in the Mounts menu. If you have booted regularly, USB debugging must be enabled.If you are not already in recovery, boot to recovery mode now.With the device powered down, hold the Volume Up & Power buttons.In Team Win Recovery Project, select thực đơn choices by tapping on the appropriately labelled button.Optional (Recommended): Select the Backup button lớn create a backup.Select Wipe and then Factory Reset.Select Install.Navigate to lớn /sdcard and select the CyanogenMod .zip package.Follow the on-screen notices to install the package.Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod first và then install any subsequent packages on top of it).Once installation has finished, return lớn the main menu & select Reboot, then System. The device will now boot into CyanogenMod.

Introduction

These instructions will hopefully assist you khổng lồ start with a stock Redmi chú ý 3, unlock the bootloader (if necessary), và then download the required tools as well as the very latest source code for CyanogenMod (based on Google’s game android operating system). Using these, you can build both CyanogenMod và CyanogenMod Recovery image from source code, và then install them both khổng lồ your device.

It is difficult to say how much experience is necessary to lớn follow these instructions. While this guide is certainly not for the very very very 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 lớn read through just to lớn 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 lớn boot into a fresh operating system you baked at home :) & once you’re an Android-building ninja, there will be no more need to lớn wait for “nightly” builds from anyone. You will have at your fingertips the skills to build a full operating system from code khổng lồ a running device, whenever you want. Where you go from there– maybe you’ll showroom a feature, fix a bug, add a translation, or use what you’ve learned khổng lồ build a new ứng dụng or port khổng lồ a new device– or maybe you’ll never build again– it’s all really up to you.

What you’ll need

A relatively recent computer (Linux, OS X, or Windows) with a reasonable amount of RAM & about 100 GB of miễn phí storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives. A USB cable compatible with the Redmi cảnh báo 3 (typically micro USB, but older devices may use mini USB or have a proprietary cable) A decent internet connection & reliable electricity :)

If you are not accustomed lớn using Linux– this is an excellent chance to lớn learn. It’s free– just tải về and run a virtual machine (VM) such as Virtualbox, then install a Linux distribution such as Ubuntu (AOSP vets Ubuntu as well). Any recent 64-bit version should work great, but the latest is recommended.


Note:

You want khổng lồ use a 64-bit version of Linux. A 32-bit Linux environment will only work if you are building CyanogenMod 6 và older. For CyanogenMod 10.1, if you encounter issues with 64bit host binaries, you can phối BUILD_HOST_32bit=1 in your environment. This is generally not needed, though, especially with CyanogenMod 10.2 and newer.


Using a VM allows Linux lớn run as a guest inside your host computer– a computer in a computer, if you will. If you hate Linux for whatever reason, you can always just uninstall và delete the whole thing. (There are plenty of places to lớn find instructions for setting up Virtualbox with Ubuntu, so I’ll leave it to you to vị that.)

So let’s begin!

Build CyanogenMod và CyanogenMod Recovery

Prepare the Build Environment


Note:

You only need to do these steps the first time you build. If you previously prepared your build environment và have downloaded the CyanogenMod source code for another device, skip to Prepare the device-specific code.


Install the SDKIf you have not previously installed adb and fastboot, install the apk SDK. “SDK” stands for Software Developer Kit, và it includes useful tools that you can use to flash software, look at the system logs in real time, grab screenshots, & more– all from your computer.

Helpful Tip

While the SDK contains lots of different things– the two tools you are most interested in for building app android are adb & fastboot, located in the /platform-tools directory.


Install the Build Packages

Several “build packages” are needed lớn build CyanogenMod. You can install these using the package manager of your choice.


Helpful Tip

A package manager in Linux is a system used to install or remove software (usually originating from the Internet) on your computer. With Ubuntu, you can use the Ubuntu Software Center. Even better, you may also use the apt-get install command directly in the Terminal. (Learn more about the apt packaging tool system from Wikipedia.)


For both 32-bit & 64-bit systems, you’ll need:

bc bison build-essential curl flex git gnupg gperf libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libwxgtk2.8-dev libxml2 libxml2-utils lzop maven openjdk-7-jdk pngcrush schedtool squashfs-tools xsltproc zip zlib1g-devIn addition khổng lồ the above, for 64-bit systems, get these:

g++-multilib gcc-multilib lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-devFor Ubuntu 15.10 (wily) & newer, substitute:

lib32readline-gplv2-dev → lib32readline6-dev

For Ubuntu 16.04 (xenial) and newer, substitute (additionally see java notes below):

libwxgtk2.8-dev → libwxgtk3.0-dev openjdk-7-jdk → openjdk-8-jdk

Java versions: Different versions of CyanogenMod require different versions of the JDK (Java Development Kit):

CyanogenMod 7 – 9: Sun/Oracle Java SE 1.6 CyanogenMod 10.1: Sun/Oracle Java SE 1.6 or 1.7 CyanogenMod 10.2 – 11.0: Sun/Oracle Java SE 1.6 or 1.7 (OpenJDK 1.7 works fine, but the build system will display a warning) CyanogenMod 12.0 – 13.0: OpenJDK 1.7 (see note about OpenJDK 1.8 below) CyanogenMod 14.1: OpenJDK 1.8

Ubuntu 16.04 (Xenial Xerus) or newer and OpenJDK: Since OpenJDK 1.7 was removed from the official Ubuntu repositories, you have a couple options:

Enable experimental OpenJDK 1.8 support in CyanogenMod 13.0 (not available in earlier version). To enable OpenJDK 1.8 support, địa chỉ this line lớn your $HOME/.bashrc file: export EXPERIMENTAL_USE_JAVA8=true.

Also see http://source.android.com/source/initializing.html which lists needed packages.

Create the directories

You will need to set up some directories in your build environment.

To create them:

$ mkdir -p ~/bin$ mkdir -p ~/android/system

Install the repo command

Enter 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

Put the ~/bin directory in your path of execution

In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor và verifying the following code exists (add it if it is missing):

# set PATH so it includes user"s private bin if it existsif < -d "$HOME/bin" > ; then PATH="$HOME/bin:$PATH"fi

Initialize the CyanogenMod source repository

Enter the following to initialize the repository:

Note: Make sure the cm branch entered here is the one you wish lớn build and is supported on your device.

$ cd ~/android/system/$ repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0

Download the source code

To start the download of all the source code khổng lồ your computer:

$ repo syncThe cm manifests include a sensible mặc định configuration for repo, which we strongly suggest you use (i.e. Don’t địa chỉ cửa hàng any options to sync). For reference, our default values are -j 4 & -c. The -j 4 part means that there will be four simultaneous threads/connections. If you experience problems syncing, you can lower this lớn -j 3 or -j 2. -c will ask repo to lớn pull in only the current branch, instead of the entire cm history.

Prepare to lớn wait a long time while the source code downloads.


Helpful Tip

The repo sync command is used to update the latest source code from CyanogenMod and Google. Remember it, as you can vị it every few days khổng lồ keep your code base fresh và up-to-date.

Get prebuilt apps (CM11 & below)

Next,

$ cd ~/android/system/vendor/cmthen enter:

$ ./get-prebuiltsYou won’t see any confirmation- just another prompt. But this should cause some prebuilt apps to lớn be loaded và installed into the source code. Once completed, this does not need to be done again.

Prepare the device-specific code


Helpful Tip – Errors during breakfast

Different maintainers cài đặt their device inheritance rules differently. Some require a vendor directory to lớn be populated before breakfast will even succeed. If you receive an error here about vendor makefiles, then jump down khổng lồ the next section Extract proprietary blobs. The first portion of breakfast should have succeeded at pulling in the device tree và the extract blobs script should be available. After completing that section, you can rerun breakfast kenzo


After the source downloads, ensure you are in the root of the source code (cd ~/android/system), then type:

$ source build/envsetup.sh$ breakfast kenzoThis will download the device specific configuration và kernel source for your device. An alternative lớn using the breakfast command is to lớn build your own local manifest. To bởi this, you will need khổng lồ locate your device on CyanogenMod’s GitHub và list all of the repositories defined in cm.dependencies in your local manifest.


Helpful Tip

If you want to know more about what source build/envsetup.sh does or simply want to lớn know more about the breakfast, brunch & lunch commands, you can head over to lớn the Envsetup help page.


Helpful Tip

Instead of typing cd ~/android/system every time you want to lớn return back to lớn the root of the source code, here’s a short command that will vị it for you: croot. To use this command, you must first run source build/envsetup.sh from ~/android/system.


Extract proprietary blobs

Now ensure that your Redmi note 3 is connected to lớn your computer via the USB cable & that you are in the ~/android/system/device/xiaomi/kenzo directory (you can cd ~/android/system/device/xiaomi/kenzo if necessary). Then run the extract-files.sh script:

$ ./extract-files.shYou should see the proprietary files (aka “blobs”) get pulled from the device and moved to the ~/android/system/vendor/xiaomi directory. If you see errors about adb being unable to pull the files, adb may not be in the path of execution. If this is the case, see the adb page for suggestions for dealing with “command not found” errors.


Note:

Your device should already be running a build of CyanogenMod for the branch you wish lớn build for the extract-files.sh script lớn function properly.


Note:

It’s important that these proprietary files are extracted to lớn the ~/android/system/vendor/xiaomi directory by using the extract-files.sh script. Makefiles are generated at the same time to lớn make sure the blobs are eventually copied lớn the device. Without these blobs, CyanogenMod may build without error, but you’ll be missing important functionality, such as graphics libraries that enable you khổng lồ see anything!


Turn on caching khổng lồ speed up build

You can speed up subsequent builds by adding

export USE_CCACHE=1to your ~/.bashrc file (what’s a .bashrc file?). Then, specify the amount of disk space lớn dedicate to ccache by typing this from the vị trí cao nhất of your app android tree:

prebuilts/misc/linux-x86/ccache/ccache -M 50Gwhere 50G corresponds to 50GB of cache. This only needs to lớn be run once and the setting will be remembered. Anywhere in the range of 25GB to 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 vị not chia sẻ the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this into consideration. See more information about ccache on Google’s apk build environment initialization page.


Helpful Tip

If you are a very active developer, working on many other projects than just Android, you might prefer to keep your android ccache independent (because it’s huge and can slow down the efficiency of ccache in your other projects). Beginning with CyanogenMod 12.1, you can specify environment variables for the location and form size of CyanogenMod’s ccache. Some syntax examples: export ANDROID_CCACHE_DIR="$HOME/android/.ccache" & export ANDROID_CCACHE_SIZE="50G".


Helpful Tip

If the build doesn’t start, try lunch and choose your device from the menu. If that doesn’t work, try breakfast & choose from the menu. The command make kenzo should then work.


Helpful Tip

A second, bonus tip! If you get a command not found error for croot, brunch, or lunch, be sure you’ve done the source build/envsetup.sh command in this Terminal session from the ~/android/system directory.


Helpful Tip

A third tip! If the build to fails while downloading Gello, you’ll need khổng lồ import a missing certificate into Maven’s truststore. Detailed instructions on how to vì that can be found here


If the build breaks…

If you experience this not-enough-memory-related error…

ERROR: signapk.jar failed: return code 1make: *** Error 1…you may want to lớn make the following change to lớn ~/android/system/build/tools/releasetools/common.py:

Search for instances of -Xmx2048m (it should appear either under OPTIONS.java_args or near usage of signapk.jar), và replace it with -Xmx1024m or -Xmx512m.

Then start the build again (with brunch).

If you see a message about things suddenly being “killed” for no reason, your (virtual) machine may have run out of memory or storage space. Assign it more resources và try again.

Install the build

Assuming the build completed without error (it will be obvious when it finishes), type:

$ cd $OUTin the same terminal window that you did the build. Here you’ll find all the files that were created. The stuff that will go in /system is in a thư mục called system. The stuff that will become your ramdisk is in a folder called root. And your kernel is called… kernel.

But that’s all just background info. The two files we are interested in are (1) recovery.img, which contains CyanogenMod Recovery, và (2) cm-13.0-20161224-UNOFFICIAL-kenzo.zip, which is the CyanogenMod installation package.

Installing a custom recovery using fastboot

See All About Recovery Images for more information about custom recoveries và their capabilities.

Connect the Redmi chú ý 3 to the computer via USB.Open a terminal on your PC & reboot the device into fastboot mode by typingadb reboot bootloaderor by using the hardware key combination for your device while it is powered off.Once the device is in fastboot mode, verify your PC sees the device by typing fastboot devicesFlash recovery onto your device by entering the following command:fastboot flash recovery your_recovery_image.imgwhere the latter part is the filename of the recovery image.Once the flash completes successfully, reboot the device into recovery khổng lồ verify the installation.Note: Some ROMs overwrite recovery at boot time so if you bởi vì not plan lớn immediately boot into recovery to install CyanogenMod, please be aware that this may overwrite your custom recovery with the stock one.

Install CyanogenMod

Back lớn the $OUT directory on your computer– you should see a tệp tin that looks something like:

cm-13.0-20161224-UNOFFICIAL-kenzo.zip
Note:

The above tệp tin name may vary depending on the version of cm you are building. Your build may not include a version number or may identify itself as a “KANG” rather than UNOFFICIAL version. Regardless, the tệp tin name will end in .zip và should be titled similarly lớn official builds.


Now you can flash the cm...zip file above as usual via recovery mode. Before doing so, now is a good time lớn make a backup of whatever installation is currently running on the device in case something goes wrong with the flash attempt. While CyanogenMod Recovery doesn’t have a backup feature, there are other custom recoveries available that do. You can also use something lượt thích Titanium Backup (root required) as an alternative.

Success! So….what’s next?

You’ve done it! Welcome lớn 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… & hopefully you’ve learned a bit on the way và had some fun too.

Now that you’ve succeeded in building CyanogenMod for your device, here are some suggestions on what to vị next.

Also, be sure khổng lồ take a glance at the Dev Center on this wiki for all kinds of more detailed information about developer topics ranging from collecting logs, understanding what’s in the source code directories, submitting your own contributions, porting CyanogenMod to lớn new devices, và a lot more.
