Mobile operating systems based on Linux, such as Ubuntu Touch, have long ceased to be just a toy for enthusiasts and have turned into a full-fledged alternative Android and iOS those who value privacy and complete control over the device. Installing this system on a regular smartphone provides access to a unique interface with gesture control, native support for desktop applications and the absence of intrusive advertising. However, the process of replacing the firmware requires a deep understanding of the architecture Linux and preparedness for possible risks.
Before taking active steps, you need to realize that standard Android and Ubuntu Touch use different ways of interacting with hardware, which makes the installation process complex and not universal. You will need to unlock Bootloader, find or create specific system images for your model and be prepared for the fact that some hardware modules may not work. In this article we will analyze in detail each stage of migration, from preparing the tools to the first loading of the new interface.
It is worth noting right away that Not all smartphones support Ubuntu Touchsince the system requires ported drivers and an adapted kernel to work. Linux. If your device is not on the list of supported ones, installation may lead to complete inoperability of the gadget without the possibility of recovery using software methods. Therefore, a thorough compatibility check is the first and most important step that cannot be ignored under any circumstances.
Checking compatibility and preparing equipment
The first step is to accurately determine the model of your device and check its status in the official community repositories. There are many ports, but stable operation is guaranteed only by those devices that have the status "Stable" or "Candidate". To check, go to the official website of the project or to the database UBports and enter the code name of your smartphone, for example, bream or hammerhead.
If your device is not on the list, this does not always mean that installation is completely impossible, but requires advanced programming skills and knowledge of operation. Device Trees. In most cases, for unsupported devices, the system will either not start or will work with critical errors, such as no connection or a non-functioning touchscreen. It is best to use flagships that were popular in the past from Google, OnePlus or Xiaomi, for which there are ready-made assemblies.
⚠️ Attention: The installation process of Ubuntu Touch requires unlocking the bootloader, which automatically leads to the complete removal of all data from the device and may void the manufacturer's warranty.
To carry out the operation, you will need a high-quality cable USB, preferably original or certified, since cheap analogues often do not provide a stable connection when transmitting large amounts of data. You also need a computer running Linux, macOS or Windows with installed drivers ADB and Fastboot. Without these tools, interaction with the phone at a low level is impossible.
Necessary tools and software
To successfully install the operating system Ubuntu Touch it is necessary to prepare a specialized set of software that will ensure interaction between the computer and the mobile device. The main tool is the utility UBports Installerthat automates most complex processes, including unlocking the bootloader and writing system partitions.
You should download software only from official resources to avoid the introduction of malicious code or the use of outdated firmware versions. In addition to the installer, the environment variables must be correctly configured on the computer to work with ADB (Android Debug Bridge). This will allow you to execute debugging commands and manage the file system of your smartphone directly from the command line.
☑️ Preparing tools
An important aspect is the version of the operating system on the computer itself. If you are using Windows, make sure that all the necessary certificates and drivers for your chipset are installed, be it Qualcomm, MediaTek or Samsung. In some cases, you may need to manually install drivers through the device manager, especially for older smartphone models that are not detected automatically.
Unlocking the bootloader and Fastboot mode
The key step before installing any custom system is unlocking Bootloader. A bootloader is a app that runs before the operating system starts and verifies the digital signature of the loaded software. Manufacturers block it to prevent the installation of uncertified systems, so this barrier must be overcome.
The unlocking process varies depending on the manufacturer. For devices Google Pixel or OnePlus it is enough to execute the command fastboot flashing unlock or fastboot oem unlock after switching to the corresponding mode. On smartphones Xiaomi or Huawei the procedure is more complicated and often requires waiting from several days to a week after submitting an application through an official account.
adb reboot bootloader
fastboot oem unlock
After entering the command, a risk warning will appear on the smartphone screen, and to confirm the action you usually need to press a combination of volume buttons. Remember that from this moment all data on the device will be permanently deleted, and the security system Android will be changed. The device will enter a state where it is ready to accept any system images.
Before unlocking the bootloader, be sure to remove the SIM card and memory card to avoid accidental damage or data loss during the flashing process.
The installation process of Ubuntu Touch via UBports Installer
The most reliable and the recommended installation method is to use the app's graphical interface UBports Installer. This tool takes on the task of selecting the correct system image that matches your model and sequentially writing it to the desired memory sections. The user can only follow the instructions on the screen and connect the device via USB when prompted by the app.
During the installation process, the installer will prompt you to select an update channel: Stable for everyday use or Devel for testing new functions. For most users, the stable branch is recommended as it is pre-tested and contains minimal critical bugs. The development branch may be unstable and contain bugs that affect the operation of the main functions of the phone.
When writing files to the phone, the progress bar may freeze at certain percentages, for example, 30% or 70%. This is normal behavior as the process takes time and depends on the speed of the port USB and the type of memory of the device. Do not interrupt the connection or disconnect the cable until the app reports a successful completion or an obvious error.
| Installation stage | User action | Expected result |
|---|---|---|
| Connection | Connect the phone in Fastboot/Recovery mode | The app detects the device |
| Channel selection | Select Stable or Devel | Loading a list of available images |
| Record image | Do nothing, wait | Progress bar reaches 100% |
| Reboot | Disconnect the cable according to instructions | First launch Ubuntu Touch |
Initial setup and system interface
After successful installation and first boot, you will see a welcome window Ubuntu Touch, which is radically different from the usual one Android. There is no list of applications in the classical sense; instead the concept of Scope'ov (areas) and gesture control is used. Swipes from the bottom up open running applications, and swipes from the sides call up system menus.
System setup begins with choosing a language, connecting to Wi-Fi and setting up an account Ubuntu One. While having an account is not strictly necessary for basic use, it syncs contacts, calendar, and allows you to install apps from the store OpenStore. The interface adapts to the screen size, but some devices with non-standard aspect ratios may experience black bars.
⚠️ Attention: Unlike Android, there is no Google Play Services, so familiar applications (WhatsApp, Instagram, banking clients) will not be installed directly. Use web versions or look for alternatives in OpenStore.
One of the unique features is the ability to connect a monitor or TV via an adapter USB-C to HDMI. In this mode, the interface transforms, providing a full-fledged desktop environment with windowed mode, which turns the smartphone into a mini-computer. This feature may not work on all devices and is dependent on the chipset supporting video output.
What is Lomiri?
Lomiri (formerly Unity 8) is a graphical front-end for Ubuntu Touch designed with touch in mind. It uses the concept of “convergence,” allowing the interface to adapt from phone to desktop.
Installing applications and working with the ecosystem
The main source of software in Ubuntu Touch is the application store OpenStore. It features native applications written specifically for this platform, as well as web applications that are wrapped in containers. The quality and quantity of software is significantly inferior Google Play or App Store, so you need to be prepared for this.
To run Androidapplications there is a project Waydroidthat creates an Android container inside Linux. However, its installation requires command line and terminal skills, as well as sufficient free memory. Not all applications work correctly, and performance may be lower than native.
For web surfing and using social networks, it is often most convenient to create “web apps”. These are shortcuts that open sites in full screen mode without an address bar, simulating the work of a native application. This allows you to use Telegram, Twitter and news feeds with an acceptable level of comfort.
The Ubuntu Touch ecosystem is focused on web technologies and open standards, rather than proprietary applications, which requires changing your smartphone usage habits.
Typical problems and methods for solving them
During operation, problems may arise with drivers, especially with communication modules and the camera. If it doesn't work 4G/LTEcheck your operator's APN settings, as automatic configuration is rare on Linux systems. It is often necessary to manually configure the access point parameters in the network settings.
Power consumption problems are also common, especially on older devices where the kernel Linux is not optimized for managing the power of specific components. In such cases, turning off unused modules (Bluetooth, GPS) and reducing screen brightness helps. The community is constantly working on optimization by releasing kernel updates.
If the device is stuck in a bootloop, you need to return to the mode Recovery and perform a factory reset (Wipe Data/Factory Reset). As a last resort, re-flashing via Fastboot cleaning all partitions will help. Always have a stock firmware image on hand Android in case you need to revert to the original state.
Is it safe to use Ubuntu Touch for banking?
Using banking applications on Ubuntu Touch is difficult due to the lack of Google Play Services and SafetyNet certification. Web versions of banks may work, but the level of security depends on the specific site and browser. For critical operations, it is better to use a separate device.
Is it possible to return Android after installing Ubuntu Touch?
Yes, it is possible. To do this, you need to unlock the bootloader again (if it is locked) and flash the stock Android image via Fastboot. All data will be deleted, so backup is required before any experiments.
Does VoLTE and VoWiFi work on Ubuntu Touch?
Support for VoLTE and VoWiFi depends solely on the specific port for your device model. In most cases, these functions do not work as they require proprietary blobs and modem integration, which are difficult to implement in an open system.
