Getting started

Linux is currently the best supported platform (tested with Ubuntu 20.04/22.04 LTS). Windows and MacOS are also well supported but you might experience more issues. So far there is no support for ARM-based systems.

Note, that Ubuntu 22.04 can be booted from a USB drive without installing it. This might be a simple solution if you face any compatibility issues.

How to run the application:

  • Download the .exe, flatpak or appropriate executable file for your OS. You might need to change permissions to run the executable. (On Windows, also install the Universal USB Drivers and other potentially drivers needed for your device.)
  • Start the desktop app and follow the instructions. You might need to allow or enable the execution of the software.

What to install?

You can use the OpenAndroidInstaller to install all kinds of custom Android ROMs and Addons like Google Apps, MicroG or the F-Droid-Store.

Adding support for new devices

Support for devices is managed by config files that describe steps and metadata of the installation process.

Finding issues to fix

The source code is hosted on GitHub. A number of the issues are marked with the "good first issue" label indicating they are suitable for someone new to the OpenAndroidInstaller code base.


Test the installer
