Replacing the operating system on a mobile device is a bold step that opens up access to a fundamentally new user experience. While tablets dominate the tablet market, alternative systems such as tablets offer a different philosophy of interaction based on gestures and convergence. Many users are looking for a way to install a full-fledged desktop environment on their gadgets, but it is important to understand the difference between terminal emulation and a native OS replacement. Android dominates the tablet market, alternative systems such as Ubuntu Touch, propose a different philosophy of interaction based on gestures and convergence. Many users are looking for a way to install a full-fledged desktop environment on their gadgets, but it is important to understand the difference between terminal emulation and a native OS replacement.
The process of installing a distribution on ARM architecture requires a deep understanding of the file system and bootloader. This article is dedicated specifically to the native installation of the UBports project, which is the successor to the original Ubuntu Touch. You will learn what technical barriers will have to be overcome and why not every tablet will be an ideal candidate for such a transformation. Linux-distribution for ARM architecture requires a deep understanding of the file system and bootloader. This article is dedicated specifically to the native installation of the UBports project, which is the successor to the original Ubuntu Touch. You'll learn what technical barriers need to be overcome and why not every tablet is an ideal candidate for this transformation.
Before taking active steps, you need to realize that by going beyond the standard firmware, you take full responsibility for the performance of the device. The process of installing a third-party OS irreversibly erases all user data and can lead to device failure if errors occur. However, for enthusiasts, this is the only way to gain control over the hardware and get rid of the pre-installed software garbage.
Technical requirements and compatibility check
The first and most critical step is to check the support of your device by the developer community. Unlike installing applications, replacing the system kernel requires ready-made drivers for a specific processor, screen, and communication modules. The project UBports supports a limited list of devices, and attempting to install the system on an unsupported tablet will only result in the creation of a "brick".
You will need to find the exact code name of your device, which often differs from the commercial name. For example, a popular tablet Nexus 7 has a code name grouper or tilapia depending on the year of manufacture. Without knowing this identifier, it is impossible to select the correct system image or use an automatic installer.
- 📱 Having an unlockable bootloader is a prerequisite for most devices.
- 🔋 A fully charged battery (minimum 80%) to prevent shutdown during firmware.
- 💻 A computer with the Linux, macOS or Windows operating system for working with firmware utilities.
- 🔌 An original or high-quality USB cable to ensure a stable connection.
It is worth noting that the processor architecture plays a key role. Most modern tablets run on chips, but older models can use chips, which require completely different system images. Check the specifications on the manufacturer's official website or in applications like ARM, however older models may use x86, which requires completely different images of the system. Check the specifications on the manufacturer's official website or in applications like CPU-Zto make sure the cores are compatible.
Preparing the working environment and tools
For successful installation, you will need specialized software that will ensure communication between the computer and the tablet in download mode. The main tool is UBports Installer, which greatly simplifies the process compared to manual firmware via fastboot i adb. This application automatically detects the device and suggests available firmware channels.
In addition to the installer, you need to prepare ADB and Fastboot drivers. On Windows this often causes difficulties, since standard drivers may not recognize the device in bootloader mode. It is recommended to use universal Google USB drivers or specialized packages from the chipset manufacturer, for example Qualcomm or MediaTek.
Create a separate folder on your desktop to store all the necessary files. This will help avoid confusion if during the process there is a need to manually download a recovery image or a specific kernel build. The directory structure should be simple and understandable so that in a stressful situation you can quickly find the file you need.
☑️ Ready for flashing
Do not forget about the need to enable USB debugging on the tablet itself. This feature is hidden in the "For Developers" menu, which is disabled by default. To activate it, you need to quickly click on the build number in the Settings → About phonesection seven times. Only after this will the item appear USB debuggingwhich needs to be switched to the active position.
Unlocking the bootloader and clearing data
Unlocking the bootloader is the process of removing manufacturer restrictions on installing unsigned software. This procedure is performed differently on different devices: from a simple command in the terminal to receiving a special unlock code through the manufacturer’s website. For devices Nexus and Pixel this is done as simply as possible, while Sony or Huawei may require complex manipulations.
⚠️ Attention: Unlocking the bootloader on most devices leads to a complete data reset (Factory Reset). All photos, contacts and applications will be permanently deleted from the tablet's internal memory.
After enabling developer mode and USB debugging, connect the tablet to the computer and put it in Fastboot mode. This is usually done using a key combination Volume Down + Power with the device turned off. In the computer terminal, enter the command fastboot devicesto make sure that the computer sees the tablet.
The unlock command itself looks like fastboot oem unlock or fastboot flashing unlock for new devices. A warning about data loss will appear on the tablet screen, which is usually confirmed by pressing the volume buttons. After confirmation, the device will reboot and wipe all data partitions.
What is OEM Unlock?
The OEM Unlock command sends a signal to the bootloader to remove the kernel digital signature verification. Without this, the system will refuse to boot any image that is not signed with manufacturer keys, making Ubuntu installation impossible. On some devices (for example, Samsung), this function is called "OEM Unlock" in the developer menu and requires account verification.
The installation process of Ubuntu Touch via UBports
When the bootloader is unlocked, you can proceed to install the operating system directly. Launch the previously installed UBports Installer on your computer. The app will offer to connect the device; Make sure the tablet is in Android or Recovery mode, depending on the installer's requirements.
The app interface will guide you through selecting the firmware channel. The Stable channel is recommended for everyday use as it contains proven builds. The RC (Release Candidate) or Dev (Development) channels may contain new features, but often suffer from instability and errors in the operation of drivers.
| Firmware channel | Stability | Relevance of kernels | Recommendation |
|---|---|---|---|
| Stable | High | Tested versions | For daily work |
| RC | Average | New functions | For testing |
| Devel | Low | The latest | For developers only |
| Edge | Critical | Experimental | Not recommended |
After selecting a channel, the process of downloading the image and recording it to the device will begin. At this moment, the Android or robot logo with an open hatch may be displayed on the tablet screen - this is normal. Under no circumstances should you disconnect the cable before the process is complete, even if the installation seems to be frozen.
If the installer freezes at the "Waiting for device" stage, try changing the USB port on your computer (preferably using a USB 2.0 port) or replacing the cable. Often the problem lies in poor contact or lack of power on the port.
Initial setup and interface of Unity 8
After successful installation and the first reboot, you will see the welcome screen Ubuntu Touch. The interface is radically different from what you're used to on Android or iOS. There is no Home button in the usual sense, and navigation is based solely on swipes from the edges of the screen.
A swipe from the bottom opens the application switcher, a swipe on the left opens the application menu, and a swipe on the right opens the notification and quick settings panel. This solution allows you to use the entire screen space for content, which is especially convenient on tablets with a diagonal of 7-10 inches. The system automatically adjusts the interface to the orientation of the device.
You will be prompted to set up your language, region, and connect to a Wi-Fi network. Please note that the application store here is called OpenStore, not Google Play. It offers native applications written specifically for Ubuntu Touch, as well as some web applications. Installing APK files from Android in this environment is impossible without complex emulators, which greatly reduce performance.
⚠️ Attention: The lack of Google services means that familiar applications like YouTube, Gmail or Maps will not work natively. You will have to use their web versions or look for alternatives in the OpenStore, such as uNav for maps or Morph Browser for web surfing.
The main feature of Ubuntu Touch is the concept of convergence: when you connect a keyboard and mouse, the interface transforms into something like a desktop environment, allowing you to work with windows applications.
Possible problems and ways to solve them
Like any custom firmware, Ubuntu Touch may not work perfectly on a particular device. The most common problems include audio not working, Wi-Fi issues, or battery draining quickly. These issues are often resolved by updating the firmware to a newer build or rolling back to a previous stable version.
If the device is stuck in a bootloop, you need to enter Recovery mode. In UBports Recovery, the menu usually allows you to perform a factory reset (Wipe Data/Factory Reset) or reflash the system again. Recovery is accessed using the key combination Volume Up + Power.
In case of complete failure ("brick"), you may need to restore stock Android firmware through the manufacturer's tools (for example, Odin for Samsung or SP Flash Tool for MediaTek). Always save a link to the original firmware of your device before starting experiments with Linux.
- 🔇 No sound: Check the mixer settings in the terminal or update the system kernel.
- 📶 Wi-Fi does not work: Try to forget the network and connect again, check the drivers.
- 🔋 Fast category: Disable unnecessary services, reduce brightness, check background processes.
Frequently asked questions (FAQ)
Is it possible to install a full-fledged Ubuntu Desktop (with GNOME or KDE) on a tablet?
No, Ubuntu Desktop is designed for architecture x86/x64 and requires resources that are rarely available on mobile ARM chips in native form. Ubuntu Touch uses the Linux kernel, but a completely different graphics stack (Lomiri) optimized for touchscreens. Launching a full-fledged desktop environment is only possible through emulation, which is extremely slow.
Will my data from Android be saved after installing Ubuntu?
No, the installation process involves a complete repartition of memory partitions and formatting of internal drives. All data will be deleted. It is recommended to copy important files to your computer or cloud storage in advance.
Is it possible to go back to Android?
Yes, if you have a saved image of the stock firmware (backup) or you can download it from the manufacturer’s website. The return procedure is called "unbricking" or runoff restoration. However, if the bootloader has been irreversibly flashed, a return may not be possible.
Does hardware video acceleration work in Ubuntu Touch?
It depends on the specific device and the quality of the drivers. On many supported devices, video playback works correctly thanks to the Android drivers (HAL) that Ubuntu Touch uses. However, heavy 4K videos or specific codecs can cause CPU load.
Is it safe to use banking apps on Ubuntu Touch?
Android banking apps do not work on Ubuntu Touch. You will only be able to use online banking through a browser. From a security point of view, the open Linux system is less susceptible to widespread Android viruses, but requires more literacy from the user in setting access rights.
