A build system for EUI official ROMs for LeEco/LeTV devices.
A bunch of scripts, binaries and helpers built-in one repository that will download, extract, modify and repack the upstream operating system for distribution. It's planned and organized for any LeEco device, not only the Le Pro3 which is my personal device.
The build system approach shines on the lines of FreedomOS which is not intrusive and not as specific as the Android Kitchen build system, which needs to rebase the third party work on every major release and doesn't support a variety of devices in the same tree.
It's fundamental, though, to say that this build system only supports the GNU/Linux platform for many reasons we shall not describe here. So, all you'd need to build LibertineOS is a GNU/Linux distribution with the proper packages installed, more on that in the Building part of the Documentation section below.
This documentation is used for "compiling" supported devices and porting new devices by creating new configuration files for them under configuration folder. The configuration file is the main component needed for creating a new LibertineOS product, understanding the variables and how the scripts work is the only obstable you might find yourself in when porting LibertineOS your device. Fortunately, we have a great documentation in place, just for you.
They are all set in the configuration for the device and EUI version we'll be building. Check the following table to have a deeper knowledge on the main variables the build system supports.
| Variable | Description | Example |
|---|---|---|
| $IDENTIFIER | Automatically created by agglutinating two other variables $CODENAME and $ROM_ID | zl1_23s |
| $DEVICE | User's globally adopted device name convention | Pro3 |
| $CODENAME | Short term for the device set by the manufacturer | zl1 |
| $ROM_ID | Lowercase EUI minor release version | 5.9.23s |
| $ROM_NAME | Zip file produced by the OEM build system | LE_ZL1_LEX720-CN-FN-WAXCNFN5902303282S-5.9.023S |
| $ROM_LINK | Downloadable zip file from OEM servers | URL/$ROM_NAME |
| $ROM_MD5 | Hash for checking if the download is not corrupted | 0006f6ca49090764695186b36bc1acfe |
| $ASSERT | Build product and device safety check before flashing process | le_zl1 |
| $RELTYPE | Release type to complement the build ID property | release-keys |
| $SYSTEMIMAGE_PARTITION_SIZE | Amount of system partition's blocks ??? | 4294967296 |
Inspecting the configuration folder will give you the "officialy" supported devices and their respective EUI versions, a device can have multiple versions and variants that may change how we will handle the installer and the software that we'll remove from the system.img.
./liberty.sh -a ${device}-${version} # Download, extract and analyze the system.img file.
./liberty.sh -b ${device}-${version} # Download, extract, remove and modify the contents of system.img file to create a flashable zip file.
The following packages need to be installed on your GNU/Linux machine in order to "compile" LibertineOS properly.
sudo pacman -S aria2 cpio zip wget rsync python python2 python-virtualenv openssl ncurses
sudo apt-get install aria2 cpio zip wget rsync python python-virtualenv openssl libncurses-dev
It's also handy to have other software available such as adb, apktool and java installed.
First of all, make sure you have the needed dependencies.
Then, clone the repository somewhere, --recursive flag will pull the needed modules.
git clone --recursive https://github.com/GalaticStryder/LibertineOS.git libertine-os
Change directory to the folder libertine-os folder.
cd libertine-os
Run the liberty.sh script in build mode, indicated by -b flag with the configuration file right after.
./liberty.sh -b Pro3-23S
- xpirt: System convertion binaries.
- Nevax07: Most build scripts and organization idea.
- amarullz: Customizable aroma installer.
- Chainfire: SuperSU modification package.
