Unlock and Install a Custom Recovery on the Zenfone 2 (1080p)

Obtaining the Bootloader Unlock Application

If the Bootloader on the Zenfone 2 (1080p) has already been unlocked, you may skip this section.

From the drop-down menu, select Android.Expand the section titled Utilities.Download the Unlock Device App.If the downloaded tệp tin is packaged in a zip archive, extract it.Open a command prompt or terminal lớn the location where the UnLock Device App app android resides.Reboot the device.

Installing recovery using fastboot

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

Download recovery — you can directly tải về the recovery image using the link below, or visit the CWM or TWRP site to kiểm tra for the latest version of custom recovery (if your device can be found there). Be careful khổng lồ select the right image! Connect the Zenfone 2 (1080p) to lớn the computer via USB.Open a terminal on your PC & reboot the device into fastboot mode by typing adb reboot bootloader or by using the hardware key combination.If your stock ROM is a Jellybean release, this should drop you into fastboot mode. If your stock ROM is an ICS release, you will likely need lớn use the Vol Down key to highlight fastboot from a boot menu and then & press Power khổng lồ select it.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.img where the latter part is the name of the tệp tin you downloaded.Once the flash completes successfully, reboot the device into recovery to lớn verify the installation.Note: Some ROMs overwrite recovery at boot time so if you vày not plan to lớn immediately boot into recovery to lớn install CyanogenMod, please be aware that this may overwrite your custom recovery with the stock one.

The Zenfone 2 (1080p) should now be ready to lớn install CyanogenMod.

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 khổng lồ your device using any method you are familiar with. The adb method is used here because it is universal across all devices and works in both Android and recovery mode. If you are in recovery mode, you may need to 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 lớn recovery mode now.No direct key comboIn Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.Optional (Recommended): Select the Backup button to create a backup.Select Wipe và then Factory Reset.Select Install.Navigate khổng lồ /sdcard và 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 & then install any subsequent packages on đứng 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 to start with a stock Zenfone 2 (1080p), unlock the bootloader (if necessary), and 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 & CyanogenMod Recovery image from source code, & then install them both to lớn 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 & breeze through the steps easily. Others may struggle over the most basic operation. Because people’s experiences, backgrounds, và intuitions differ, it may be a good idea to 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 khổng lồ boot into a fresh operating system you baked at home :) and once you’re an Android-building ninja, there will be no more need lớn wait for “nightly” builds from anyone. You will have at your fingertips the skills to lớn build a full operating system from code lớn a running device, whenever you want. Where you go from there– maybe you’ll địa chỉ a feature, fix a bug, địa chỉ a translation, or use what you’ve learned to lớn build a new ứng dụng or port to lớn a new device– or maybe you’ll never build again– it’s all really up to lớn you.

What you’ll need

A relatively recent computer (Linux, OS X, or Windows) with a reasonable amount of RAM & about 100 GB of không lấy 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 Zenfone 2 (1080p) (typically micro USB, but older devices may use mini USB or have a proprietary cable) A decent mạng internet connection và reliable electricity :)

If you are not accustomed to lớn using Linux– this is an excellent chance khổng lồ learn. It’s free– just download 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 lớn use a 64-bit version of Linux. A 32-bit Linux environment will only work if you are building CyanogenMod 6 & older. For CyanogenMod 10.1, if you encounter issues with 64bit host binaries, you can mix BUILD_HOST_32bit=1 in your environment. This is generally not needed, though, especially with CyanogenMod 10.2 & newer.


Using a VM allows Linux to 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 & delete the whole thing. (There are plenty of places to find instructions for setting up Virtualbox with Ubuntu, so I’ll leave it to you to do that.)

So let’s begin!

Build CyanogenMod & CyanogenMod Recovery

Prepare the Build Environment


Note:

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


Install the SDKIf you have not previously installed adb and fastboot, install the game android SDK. “SDK” stands for Software Developer Kit, và it includes useful tools that you can use lớn flash software, look at the system logs in real time, grab screenshots, và 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 game android are adb & fastboot, located in the /platform-tools directory.


Install the Build Packages

Several “build packages” are needed to 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 lớn 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) & 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 lưu ý about OpenJDK 1.8 below) CyanogenMod 14.1: OpenJDK 1.8

Ubuntu 16.04 (Xenial Xerus) or newer và 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, showroom 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 khổng lồ 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 & 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 & 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 to lớn build và 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 tải về of all the source code khổng lồ your computer:

$ repo syncThe centimet manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. Don’t showroom any options khổng lồ sync). For reference, our default values are -j 4 and -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 lớn pull in only the current branch, instead of the entire cm history.

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

Helpful Tip

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


Get prebuilt apps (CM11 and 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 lớn be loaded & installed into the source code. Once completed, this does not need to lớn be done again.

Prepare the device-specific code


Helpful Tip – Errors during breakfast

Different maintainers thiết đặt their device inheritance rules differently. Some require a vendor directory khổng lồ be populated before breakfast will even succeed. If you receive an error here about vendor makefiles, then jump down to the next section Extract proprietary blobs. The first portion of breakfast should have succeeded at pulling in the device tree & the extract blobs script should be available. After completing that section, you can rerun breakfast Z00A


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

$ source build/envsetup.sh$ breakfast Z00AThis will download the device specific configuration và kernel source for your device. An alternative to lớn using the breakfast command is to lớn build your own local manifest. To bởi vì this, you will need to lớn locate your device on CyanogenMod’s GitHub & list all of the repositories defined in cm.dependencies in your local manifest.


Helpful Tip

If you want to lớn 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 lớn the root of the source code, here’s a short command that will bởi vì it for you: croot. Khổng lồ use this command, you must first run source build/envsetup.sh from ~/android/system.


Extract proprietary blobs

Now ensure that your Zenfone 2 (1080p) is connected to lớn your computer via the USB cable và that you are in the ~/android/system/device/asus/Z00A directory (you can cd ~/android/system/device/asus/Z00A if necessary). Then run the extract-files.sh script:

$ ./extract-files.shYou should see the proprietary files (aka “blobs”) get pulled from the device và moved lớn the ~/android/system/vendor/asus directory. If you see errors about adb being unable to lớn 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 to build for the extract-files.sh script to lớn function properly.


Note:

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


Turn on caching khổng lồ speed up build

You can tốc độ up subsequent builds by adding

export USE_CCACHE=1to your ~/.bashrc file (what’s a .bashrc file?). Then, specify the amount of disk space to dedicate khổng lồ ccache by typing this from the đứng đầu of your apk tree:

prebuilts/misc/linux-x86/ccache/ccache -M 50Gwhere 50G corresponds khổng lồ 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 khổng lồ 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan khổng lồ build for several devices that do not cốt truyện 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 android build environment initialization page.


Helpful Tip

If you are a very active developer, working on many other projects than just Android, you might prefer lớn keep your android ccache independent (because it’s huge & 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 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 & choose your device from the menu. If that doesn’t work, try breakfast and choose from the menu. The command make Z00A 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 khổng lồ fails while downloading Gello, you’ll need lớn import a missing certificate into Maven’s truststore. Detailed instructions on how to vì chưng 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 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), & 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 folder called system. The stuff that will become your ramdisk is in a folder called root. Và 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-13.0-20161225-UNOFFICIAL-Z00A.zip, which is the CyanogenMod installation package.

Install CyanogenMod

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

cm-13.0-20161225-UNOFFICIAL-Z00A.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 and should be titled similarly khổng lồ official builds.


Now you can flash the cm...zip tệp tin above as usual via recovery mode. Before doing so, now is a good time to 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 to 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… and hopefully you’ve learned a bit on the way & had some fun too.

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

Also, be sure to 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 new devices, và a lot more.
