Many users are faced with a situation where their smartphone stops receiving official updates from the manufacturer, although the hardware is quite capable of running a more recent version of the operating system. Android 10 brought many important changes, including a full-fledged dark theme, improved privacy controls and new gesture navigation. If your device is stuck on Android 9 Pie, but you want to get newer features, you will have to look for alternative ways to solve the problem.
The process of migrating to a new version of the system can range from a simple check of settings to complex manipulation of system files. It is important to understand that installing a newer version of Android on an unsupported device always carries the risk of turning your smartphone into a “brick.” Before proceeding with any actions, you need to be clear about the difference between an official update over the air (OTA) and manual installation of the firmware via a computer.
In this article we will analyze in detail all the available methods, assess the risks and prepare your device for the procedure. You should not ignore the preparatory stage, since data loss is the most common problem in unsuccessful software experiments. Let's determine which method is right for your case.
Compatibility assessment and official methods
The first step should always be to carefully check for official updates. Manufacturers often release updates in waves, and it’s possible that your Samsung Galaxy or Xiaomi Redmi update simply hasn’t arrived yet. Go to Settings → System → System update and click “Check for updates”. If the server responds that the system is up to date, but you know about the release of Android 10 for your model, you can try changing the region or using the official PC software.
For Samsung devices there is a app Smart Switchthat sometimes sees updates before they arrive over the air. Similarly, for Huawei and Honor it was used HiSuite, and for Xiaomi - Mi Flash Tool (with caution). These tools allow you to update the firmware by connecting your smartphone via USB cable to your computer. This is the safest method, as it does not require unlocking the bootloader and maintains the warranty.
⚠️ Attention: If the manufacturer's official website does not offer Android 10 for your model, this means that the processor drivers are not optimized for the new version. An attempt to force the installation of official firmware from another model will lead to a breakdown.
However, if the manufacturer has officially stopped supporting, no amount of dancing with a tambourine will force the phone to update through the standard menu. In this case, the only way left is to install custom firmware. This requires obtaining root access Root and unlocking Bootloaderwhich will automatically void the device warranty.
Device preparation and backup
Before you start any manipulations with the system partition, you need to secure your data. The flashing process is almost guaranteed to lead to the complete deletion of all files, photos and contacts. Backup is not just a recommendation, but a mandatory security requirement. Use Google cloud services or local saving on your PC.
You will need a high-quality USB cable, preferably an original one, since cheap analogues can cause connection breaks at a critical moment. Also make sure that all necessary ADB drivers and Fastboot are installed on your computer. Without them, the computer simply will not see the smartphone in download mode.
Special attention should be paid to battery charge. Lithium-ion batteries may behave unstable under load while recording data. If the process is interrupted due to discharge, restoring the system will be extremely difficult, and in some cases impossible without a programmer.
Unlocking the bootloader and installing Recovery
The bootloader (Bootloader) is a app that runs before the operating system and checks software integrity. It is blocked by default to prevent installation of uncertified code. To unlock on different devices, different methods are used: from entering a code on the manufacturer’s website to flashing a special file via Fastboot.
After unlocking, you need to install a custom recovery menu, for example, TWRP (Team Win Recovery Project). Standard Recovery can only reset settings or install official updates signed by the manufacturer. TWRP, on the other hand, allows you to install any ZIP archives, make full system backups and clean partitions.
fastboot flash recovery twrp-3.5.2-0-device.img
fastboot boot twrp-3.5.2-0-device.img
This command loads temporary Recovery for the initial installation. It is important not to reboot the system in normal mode immediately after flashing TWRP, otherwise stock Android will overwrite Recovery back to stock. You need to immediately boot into recovery mode by holding down a combination of buttons (usually Volume Down + Power).
Searching and selecting suitable firmware
The most critical stage is finding the correct firmware file. For Android 10, there are ports from independent developers for devices that have not officially received it. The main sources are forum XDA Developers and specialized sites like 4PDA. You need to search strictly by the code name of your device (for example, guacamole for OnePlus 7), and not by the marketing name.
There are two main types of custom firmware: AOSP (pure Android, like Google) and UI-based (modified versions of the MIUI, OneUI, ColorOS shells). AOSP firmware usually works faster and more stable on old hardware, but lacks the manufacturer's proprietary features. UI-based versions retain the familiar interface, but can be heavier.
| Type. firmware | Stability | Functional | Installation complexity |
|---|---|---|---|
| LineageOS | High | Basic (AOSP) | Medium |
| Pixel Experience | Very high | Google Pixel features | Low |
| Resurrection Remix | Medium | Maximum customization | High |
| MIUI/OneUI ports | Low/Medium | Proprietary functionality | High |
Read the firmware topic carefully before downloading. Developers mark the statuses: Stable (stable), Beta (there are bugs) or WIP (Work In Progress - not everything works). For daily use, choose only Stable versions with a note that critical functions (camera, calls, Wi-Fi) are working properly.
The process of installing Android 10 manually
After TWRP is installed and the firmware is downloaded, you can proceed to the actual installation. Copy the ZIP archive with the firmware and, if necessary, the Google Apps package (GApps) to the internal memory or SD card. First of all, you need to clear the data (Wipe). data-i="104">In the menu
On the menu Wipe select Dalvik / ART Cache, System, Data i Cache. Do not select Internal Storage, otherwise you will delete the firmware file itself. This step is called “Clean Flash” and is required when switching between different versions of Android or different firmware. to avoid file conflicts.
Next go to menu Install, select the archive with the firmware and confirm the installation by swiping. Wait for the process to complete. If you are using the firmware without built-in Google services, immediately after installing the system (until you reboot) install the GApps archive. Only then click. data-i="111">⚠️ Attention: The first launch after installing custom firmware can last from 5 to 15 minutes. Do not panic if the Android logo hangs for a long time - the system optimizes applications. If the phone freezes for more than 20 minutes, you will need to reinstall it. Reboot System.

Possible errors and ways to eliminate them
Even if you strictly follow the instructions, problems may arise. One of the most common is (cyclic reboot). If the phone constantly reboots, go to Recovery and try Wipe Dalvik/Cache. If this does not help, the firmware may be incompatible with your device revision or the boot file is damaged. Bootloop (cyclic reboot). If your phone keeps rebooting, go to Recovery and try Wipe Dalvik/Cache. If this doesn't help, the firmware may be incompatible with your device revision or the boot file may be corrupted.
Another common one. the problem is a broken camera or fingerprint sensor. This is due to the fact that proprietary drivers (blobs) from Android 9 may not work correctly in Android 10. In such cases, searching for alternative firmware or waiting for updates from the developer that correct the operation of the equipment helps.
If the phone has stopped responding to commands and is not included in Recovery, you may have locked the bootloader with inappropriate firmware. In this case, only flashing the stock image via the EDL (for Qualcomm) or Download Mode (for Samsung) using special utilities, such as QPST or Odin.
Frequently asked questions (FAQ)
Is it possible to upgrade to Android 10 without losing data?
When using official OTA update data is saved. When installing custom firmware via TWRP, complete deletion of data (Wipe Data) is a prerequisite for stable operation, so it is necessary to save photos and contacts in advance.
Can my old phone work normally on Android 10?
Android 10 requires more resources than previous versions. If your device has less than 3 GB of RAM and a weak processor, the system may be slow. In this case, it is better to stay on Android 9 or choose lightweight firmware (Lite).
Is it safe to use banking applications on custom firmware?
By default, an unlocked bootloader and the presence of root access block the operation of banking applications and Google Pay. However, using Magisk modules (Hide, Zygisk), you can successfully hide these changes and use applications without problems.
Where can I find ADB and Fastboot drivers?
The official Platform Tools package is available on the Android Developers website. There are also minimalistic installers that automatically install drivers into the system when the device is connected.
