How to switch to another version of Android: official and unofficial methods

Moving to a new version of Android is not just an interface update, but a complete transformation of the capabilities of your smartphone. New security features, improved performance, support for modern applications, and even extended device life all depend on keeping the operating system up to date. However, the update process often raises questions: why doesn’t the manufacturer offer a new version, is it possible to install it manually, and what risks does this carry?

In this article we will analyze all possible scenarios: from automatic updating through settings to manual installation of custom firmware. You'll learn how to check your device's compatibility, prepare it for upgrading to a different version of Android, and what to do if something goes wrong. We will pay special attention data security because incorrect actions can lead to loss of information or even “bricking” the phone.

It is important to understand that not all devices support the latest versions of Android. Manufacturers often limit updates for older models, and some brands (like Google Pixel or OnePluso) offer longer support than others. If your smartphone does not officially receive updates, this does not always mean a dead end - there are alternative methods, which we will discuss below.

1. Checking the current version of Android and compatibility

Before attempting to update the system, you need to understand what version of Android is installed on your device and whether the manufacturer supports upgrading to a newer one. This information will determine which update method is available to you.

To find out the current version:

• 📱 Open Settings → About phone (or About tablet).
• 📊 Find the item Android version —the number will be indicated here (for example, Android 13 or Android 14).
• 🔍 Scroll down to Build number —this will help with the search firmware.

Now check if your device supports the update:

• 🌐 Go to the manufacturer's official website (for example, Samsung Members, Xiaomi Community, Google Support).
• 🔎 Enter the device model in the search (for example, Samsung Galaxy S22 Ultra or Xiaomi Redmi Note 11).
• 📋 Study the "Software Updates" or "Support" section - there should be information about the latest available version. Some manufacturers (for example, on devices without Google services) use their own shells instead of standard Android. In this case, updates may arrive on a different schedule or at all. missing.

• 🔧 Ability to fine-tune the interface.

Risks:

• ⚠️ Loss of warranty (if the device is under warranty).
• 🔋 Possible problems with the battery or performance.
• 📱 Some functions (for example NFC or camera) may not work correctly.

Basic steps for installing custom firmware:

1. Unlock bootloader (bootloader) To do this, you need to enable Developer options (click on the build number in Settings → About phone), then activate OEM unlocking.
2. Install custom recovery (for example, TWRP). This is a special environment for installing firmware.
3. Download the appropriate firmware from the official website (for example, lineageos.org or forum.xda-developers.com).
4. Reboot into recovery, do full backup current system, then flash the new firmware.

Important: before installing custom firmware, be sure to check its compatibility with your phone model. Installing firmware from another model will cause the device to not work ("brick"). data-i="162">Before installing custom firmware, read the reviews on the forums (for example, XDA Developers or w3bsit3-dns.com).

2. Unlock the bootloader (if it is locked).
3. Install the firmware via Fastboot or Odion (for Samsung).

On some devices (for example, Google Pixel) a rollback is possible via Android Flash Tool without data loss, but this is an exception, not rule.

Why doesn’t the manufacturer release an update for my phone?

The reasons may be different:

• 📅 Outdated hardware - new versions of Android require more resources, and older processors may not be able to handle it.
• 💰 Economic feasibility —it is more profitable for manufacturers if you buy a new phone.
