Moving to a new version of the operating system is always an exciting step for the owner smartphone. Users stuck on Android 9.0 Pieoften wonder if they can get fresh features. Android 10. This update brings a dark theme, new navigation gestures, and improved privacy controls. However, the installation process is not always obvious, since device manufacturers implement support for their gadgets differently.
Before you begin, you need to assess the real situation with your device. Many budget models released in 2018–2019 may not have received an official update. In this case, the only solution is to install custom firmware, which requires certain skills. If your phone is on the list of supported ones, the procedure can be performed using standard means or through a computer.
The main goal of this article is to guide you through all stages of migration with minimal risks of data loss. We will look at both standard methods through the settings menu, and manual installation of firmware images for advanced users. Remember that any manipulation of the system software carries potential risks, so care is paramount here.
Checking compatibility and official update status
The first and most important step is to find out whether an upgrade is provided for your specific model by the manufacturer. Large vendors, such as Samsung, Xiaomi or OnePlususually publish lists of devices that will receive the new OS. You can find this information on the official brand support forum or in the news section on the website.
The easiest way to check for an update is to look at the settings of the smartphone itself. The system itself will contact the server and tell you if there is a new version available. To do this, go to section Settings → System → System update. If the device sees the update package up to Android 10, you are lucky, and the process will be as safe as possible.
⚠️ Attention: If the settings say that the system is up-to-date, but you know for sure that Android 10 has been released for your model, the update may be coming waves. In this case, you should wait a few days or check availability manually through the menu.
It often happens that the phone was purchased in another region or is a “gray” import. In such cases, official servers may not see your device due to regional firmware mismatch. Then the user has to look for global versions of the software or resort to more complex flashing methods, changing the region identifier.
Preparing the device for the update procedure
The success of any technical operation depends 90% on quality preparation. Before you begin downloading and installing a new system, you must complete a number of mandatory steps. Ignoring these steps can lead to the loss of contacts, photos, or even turning your smartphone into a brick.
Creating a complete backup of your data is critical. Even if the manufacturer promises the safety of files during updates, failures do occur. Use cloud services like Google Drive to synchronize contacts and calendar, and copy photos and videos to a computer or external drive.
- 🔋 Charge the battery to at least 60-70%, since the installation process can take from 20 minutes to an hour.
- 💾 Free up space in the internal memory for downloading and unpacking files may require up to 5-8 GB of free space.
- 📶 Ensure a stable connection to the Wi-Fi network so that downloading large amounts of data is not interrupted and does not exhaust mobile traffic.
It is also recommended to disable any installed ad blockers, VPN services or antiviruses that may interfere with the network connection while checking the integrity of files. After the update, they can be activated again without any problems for the system.
☑️ Ready for update
Automatic update over the air (OTA)
This is the most preferred method for most users, since it does not require a connection to a computer and deep technical knowledge. The OTA (Over-The-Air) mechanism will download the required package, check its checksum and offer to install.
The process is launched from the settings menu. After clicking the "Check for updates" button, the download will begin. The waiting time depends on the speed of your Internet connection and the size of the package, which for the transition from Pie to Android 10 can be 1.5–2.5 GB.
When the download is completed, the system will prompt you to restart the device for installation. At this moment, the phone will turn off and the android logo with a progress indicator will appear on the screen. Do not touch the device at all during this period. Any pressing of buttons or attempts to remove the battery may disrupt the process of writing system partitions.
If the update has been downloaded but is not installed, try clearing the "Update Downloader" application cache in application settings before trying again.
After the first turn on, you will see welcome screen of the new OS version. Initial setup and optimization of applications may take another 10–15 minutes. At this time, the phone may work slower than usual, this is normal, since the system rebuilds the application cache for new libraries Android Runtime.
Manual installation of firmware via a computer
If the automatic method does not work, you will have to act manually. This method requires a PC, a USB cable, and a downloaded firmware image specifically for your model. An error in choosing a file can lead to the device not working, so check the model and region three times.
Different utilities are used for different manufacturers. For example, for Moto and Lenovo is often used RSD Lite, for Samsung — Odin, and for Xiaomi — Mi Flash Tool. These apps should only be downloaded from official websites or trusted forums to avoid malware.
Usually the process is as follows: the phone is put into a special download mode (Download Mode or Fastboot). This is done by using a combination of buttons, for example, holding Volume Down + Power when the screen is off. Then the device is connected to the PC, and the app selects the firmware file to start recording.

fastboot reboot
After the process is completed, a success message (Pass or Success) should appear in the app log. The phone will automatically reboot. The first startup after manual firmware can be long, sometimes up to 5-7 minutes, until the desktop appears.
What to do if the computer does not see the phone?
Make sure that the ADB and Fastboot drivers are installed. Try a different USB cable (preferably the original one) and a different USB port, preferably USB 2.0 rather than 3.0, as some older boot loaders do not work correctly with high-speed ports.
Installation via Recovery Mode (Memory Card)
There is an alternative update method without using a computer, but using a microSD memory card. It is suitable for devices that have a card slot and an unlocked bootloader, or for those who use a custom recovery, for example TWRP.
You need to download the zip archive with the update and place it in the root of the memory card. Next, the phone turns off and turns on in Recovery mode. The standard menu is called by the combination Volume Up + Power. In the menu that appears, you need to select the item Apply update from SD card.
| Stage | Action | Risk |
|---|---|---|
| Preparation | Copying a zip file to SD card | Low |
| Enter mode | Load to Recovery (buttons) | Low |
| Installation | File selection and confirmation | Medium |
| Cleaning | Wipe Cache/Dalvik (recommended) | Average |
It is important to note that When using stock (factory) Recovery, installation of updates signed by the manufacturer goes smoothly. However, if you try to install custom firmware through the stock menu, the system will throw a signature error. In such cases, preliminary unlocking of the bootloader is required.
⚠️ Attention: Before installing via Recovery, it is strongly recommended to make a full backup of the EFS or NVData partition, where IMEI and network settings are stored. Their loss will cause the phone to stop receiving the cellular network.
Possible problems and their solutions
Even if you follow all the instructions, unexpected difficulties may arise. One of the common problems is the “bootlap”, when the phone endlessly reboots at the logo. This often happens if a data reset (Wipe Data) was not performed before installing a major update to the Android version.
Another common situation is an error when checking the integrity of the package. This may mean that the file was not downloaded completely or was damaged when written to the media. In this case, you should download the firmware image from another source and check its hash sum (MD5 or SHA1), if it is provided by the developer.
If after the update the phone begins to discharge quickly or overheat, give it a couple of days to adapt. The system performs background file indexing and database optimization. If the problem persists for more than a week, it may be worth performing a full factory reset on the new version of the system.
Most errors after the update can be resolved by a full data reset (Factory Reset), but remember that this will delete all information from the phone.
Frequently asked questions (FAQ)
Will the update delete my photos and applications?
When updating through official channels (OTA) or signed factory firmware, user data is usually preserved. However, if you manually flash it or switch between different regions (for example, from the Chinese version to the global version), the data will be completely deleted. Always make a backup copy!
Is it possible to roll back to Android 9?
Yes, it is possible, but the procedure is more complicated than updating. You will need to find the Android 9 firmware archive for your model and install it via your computer in Fastboot or Download mode. Often, this requires unlocking the bootloader, which will also erase all data.
Why does the update not arrive even though the phone is supported?
Manufacturers release updates gradually to reduce the load on the servers. The region where the device is sold and the telecom operator also have an impact. If you can't wait, you can try changing the region in the settings (if there is an option) or updating manually.
Can my old phone run fast on Android 10?
Android 10 is better optimized than previous versions, and often runs even faster on older hardware thanks to improved memory management. However, if the device has less than 3 GB of RAM, operation may be less smooth due to the increased demands of modern applications.
