Tablet owners often are faced with a situation where the manufacturer stops releasing official updates for their device. Operating system remains on the old version, which leads to incompatibility with modern applications and security vulnerabilities. However, there are several ways to solve this problem and upgrade the software version.
The update process can vary from a simple click of a button in the settings to a complex flashing procedure using a computer. The choice of method depends on your model, the availability of rights, and the availability of custom firmware on the network. It is important to understand that any intervention in the system carries risks, so you must carefully study all the steps before starting work. gadget, availability of rights root and the availability of custom firmware on the network. It is important to understand that any intervention in the system carries risks, so you must carefully study all the steps before starting work.
In this article we will analyze in detail all available methods, from standard tools to advanced tools for enthusiasts. You will learn how to check the relevance of the software, where to look for third-party assemblies and what precautions should be taken so as not to turn the tablet into a “brick.”
Official update through settings (OTA)
The easiest and safest way to upgrade the version is to use the built-in function OTA (Over-The-Air). Manufacturers periodically send updates over the air if the device is still under support. First, make sure that the tablet is connected to a stable network Wi-Fi and the battery level is at least 50%.
Go to the menu Settings → About tablet (or System). Here you will find the item System update or Software update. Click the test button. If the server detects a new version, the download will begin. After the download is complete, the device will prompt you to reboot for installation.
If the system reports that you have the latest version installed, but you know that there is a newer Android for your model, perhaps the update comes in waves. In this case, you should wait a few days or clear the update service cache through the developer menu.
⚠️ Attention: Do not interrupt the OTA installation process. If the battery runs out during flashing, the device may stop booting and will require urgent recovery via PC.
Before running the OTA update, free up at least 5 GB of internal memory. The system needs space to unpack the installation package before installation.
Manual installation of official firmware
When the automatic update does not work, you can try installing the firmware manually. This method requires downloading a system image file (.zip or .img) from the manufacturer's official website. You will need a computer and a data cable.
Download the latest firmware strictly for your model. Check your device region and version bootloader. Version mismatches may result in signature verification failure. Place the file in the root of the internal memory or on a microSD card.
To start the installation, you must go to recovery mode (Recovery Mode). This is usually done by turning off the tablet and holding down a combination of buttons (for example, Volume up + Power). In the recovery menu, select Apply update from storage and specify the downloaded file.
- 📁 Download the firmware only from the manufacturer's official portal.
- 🔋 Charge the device to 100% before starting procedures.
- 💾 Make a backup copy of all personal data to an external storage device.
⚠️ Attention: Manual installation of official firmware often leads to a complete data reset (Wipe Data). Make sure that your photos and documents are saved in the cloud.
☑️ Preparing for manual firmware
Using custom recovery (TWRP)
If official methods have been exhausted, the only way to get a new Android is to install custom firmware. To do this, you will need to replace the standard recovery menu with TWRP (Team Win Recovery Project). This gives full control over memory partitions and allows you to install unsigned images.
The process begins with unlocking the bootloader (Bootloader). On many devices, this requires obtaining a special unlock code on the vendor's website or using commands fastboot. After unlocking, the TWRP image is loaded via the computer with the command fastboot flash recovery twrp.img.
After installing TWRP, download the appropriate custom firmware (for example, LineageOS, Pixel Experience) and the Google services package (GApps). Boot into recovery mode, make a full backup of the current system (Nandroid Backup), wipe partitions (Wipe) and install new files through the menu Install.
What is Nandroid Backup?
This is a complete copy of the current state of the system, including the bootloader, system, data and cache. Unlike a regular file backup, Nandroid allows you to restore the tablet exactly to the state before the firmware, even if it does not turn on.
Installing custom software gives access to functions not available in the stock version, but voids the device's warranty. In addition, some banking applications may stop working due to protection. SafetyNet.
Comparison of update methods
The choice of method depends on your technical skills and goals. A regular update guarantees stability, but limits the Android version to the latest available from the manufacturer. Custom firmware provides up-to-date software, but takes time to configure.
The table below compares the main characteristics of various methods for upgrading the system version. This will help you weigh the pros and cons before starting work.
| Method | Complexity | Risk of data loss | Available Android version |
|---|---|---|---|
| OTA (By air) | Low | Low | Official only |
| Manual (PC) | Medium | High | Official (any) |
| TWRP + Custom ROM | High | Critical | Newest (unofficial) |
| ADB Sideload | Average | Average | Official |
Using custom firmware is the only way to get Android 13 or 14 on devices that have officially settled on Android 10 or 11.
Work with ADB and Fastboot
For advanced users, indispensable tools are ADB (Android Debug Bridge) and Fastboot. They allow you to control the device from a computer at a low level. With their help, you can send commands to install updates, bypassing the tablet interface.
To use these utilities, you need to install Platform Tools on your PC and enable the “USB Debugging” mode in the developer menu on the tablet. Connect the device with a cable and check the connection with the command adb devices. If the device is displayed, you can proceed to the firmware.
To install the update via ADB, use the sideloadmode. In the recovery menu, select Apply update from ADB, and on your computer run the command:
adb sideload update_package.zipThis method is convenient because it does not require copying files to the internal memory of the tablet, which is important if there is not enough space. However, the data transfer speed is limited by the bandwidth of the USB cable.
⚠️ Attention: The developer menu interfaces and item names may differ depending on the manufacturer's shell (MIUI, OneUI, ColorOS). Always check the current documentation for your model.
Possible problems and their solution
Unforeseen difficulties may arise in the process of upgrading the Android version. The device may freeze on the logo, go into a cyclic reboot (bootloop) or stop responding to presses. Most often this is due to a driver conflict or damaged firmware files.
If the tablet does not turn on after the update, try entering the mode Recovery and performing a factory reset (Wipe data/factory reset). In more complex cases, you will need to flash the bootloader via mode Fastboot or use specialized software like Odin (for Samsung) or SP Flash Tool (for MediaTek).
Sometimes after the update the sensor or Wi-Fi stop working. This is a sign that firmware from another modification of the device was installed. In this case, it is urgent to find and install the correct stock firmware dump.
What to do if the tablet is stuck on the logo?
Try to perform a “hard reboot” by holding down the power button for 10-15 seconds. If this does not help, go to Recovery Mode and select Wipe Cache Partition. Do not delete user data right away, try clearing only the cache.
Is it possible to roll back the Android version back?
Yes, but it is more complicated than updating. You will need to find the archive of the old official firmware and install it via Fastboot or the manufacturer's tool. Please note that some devices have downgrade protection, which blocks the installation of older versions of the bootloader.
Will the warranty expire after updating?
Updating through official methods (OTA or the manufacturer's website) does not affect the warranty. However, unlocking the bootloader and installing custom recovery (TWRP) in 99% of cases will void the manufacturer's warranty.
Why do you need to update Android?
New versions bring fixes for security vulnerabilities, improve power consumption and add support for new Wi-Fi and Bluetooth standards. In addition, many modern applications require a minimum version of the API, which older systems do not provide.
