Updating the operating system on Huawei smartphones is not just changing a number in the settings, but a significant improvement in performance and security. The transition to a shell EMUI 10based on the core Android 10brought users the famous dark mode feature, improved gesture control and processor optimization. Many owners of devices of previous generations are still looking for ways to activate these functions on their gadgets.
The firmware process may seem complicated for an untrained user, but Huawei has provided several official channels for distributing updates. Depending on the model of your device and the region of sale, the path to the desired software version may be through the standard settings menu, a proprietary PC utility, or recovery mode. It is important to understand that before starting any manipulations, it is necessary to assess the risks and prepare the device.
In this article we will analyze in detail all the legal methods of switching to Android 10. We will discuss the nuances of working with beta versions, features of installation via a computer and actions in case of errors. Follow the instructions sequentially to turn your smartphone into a modern device without losing personal data.
Preparing your smartphone before installation
The first step towards a new system is to thoroughly prepare the device. Ignoring this step can lead to the loss of photos, contacts, or even turning your phone into a “brick.” Make sure that the battery level is at least 50-60%. The update process is energy-consuming, and a sudden power outage while writing system files is fatal.
Back up all important data. Despite the fact that standard update methods usually preserve user information, human error or a glitch in the firmware files can play a cruel joke. Use Huawei Cloud services or copy files to your computer via USB cable. Free up internal memory: for correct unpacking and installation of the update package, a minimum of 5-8 GB of free space is required.
⚠️ Attention: If custom firmware is installed on your device or changes have been made to the system partition (root access), the official update may not install or cause a cyclic reboot. In this case, a full reset to factory settings is required with the restoration of stock recovery.
Check the stability of the Internet connection. To download large update packages, which often weigh more than 3-4 GB, it is recommended to use high-speed Wi-Fi. mobile data can be unstable and traffic can be expensive. Also disable any third-party antivirus or memory cleaners that may be blocking system processes from accessing installation files.
☑️ Ready for update
Updating via the built-in HiCare service
The easiest and safest way to get a new version of the software is to use the built-in application HiCare (in new versions of the shell it may be called Support). This method checks the compatibility of your specific serial number with available firmwares. Go to the application and find the section responsible for servicing the device.
Click on the icon Update or Upgrade. The system will contact Huawei servers and check for a new version for your region. If an update to EMUI 10 is available, you will see a download button. The process is automated: the phone itself will download the package, check its integrity and offer a reboot for installation.
Sometimes it happens that the official update does not arrive over the air (OTA), although it has already been released for your model. In this case, you can try changing the region inside the HiCare application. Go to My → Settings → Region and select the country where the update is being distributed more actively (for example, Russia or Germany). After changing the region, reboot your smartphone and check again.
You should remember that forcibly changing the region to receive updates may have consequences. After installing a new version, the interface of some system applications may remain partially in the language of the selected region. You can usually return the original region in the settings immediately after installation is complete, but some services may require additional configuration.
Before changing the region in the HiCare application, write down the current network and access point (APN) settings, since after returning the region they may be reset to the operator's standard values.
Using the HiSuite app on a computer
If the mobile application does not see updates, the desktop version of the proprietary software comes to the rescue - HiSuite. This method is considered more reliable, since the download occurs directly to the computer, bypassing potential mobile network errors, and the installation takes place over a stable USB connection. Download the latest version of the app from the official Huawei website for PC.
Connect your smartphone to the computer using the original cable. A request for permission to debug or install drivers will appear on the phone screen - confirm the action. In the app interface on your computer monitor, find the Update (Update) button. HiSuite will scan the device and compare the current firmware version with the server database.
If the Android 10 version is available, the app will offer to download and install it. During the installation process, the phone screen will go dark or display the Huawei logo. Do not disconnect the cable under any circumstances and do not close the app on your PC until a success message appears. Interrupting the process while writing data to flash memory may damage the partition structure.
| Parameter | Over-the-air (OTA) update | Update via HiSuite | eRecovery mode |
|---|---|---|---|
| Download speed | Depends on Wi-Fi | High (cable) | Medium (Wi-Fi) |
| Risk failure | Medium | Low | Low |
| Data saving | Yes | Yes (usually) | No (full reset) |
| Difficulty | Low | Medium | High |
Sometimes HiSuite may report that you have the latest version installed, even if you know about the existence of newer software. In such a situation, clearing the app cache on your PC or using the “System Recovery” function in the same menu helps. This function will forcibly download the latest firmware and reinstall it, correcting possible software errors of the current system.
Recovery via eRecovery mode
Mode eRecovery is an emergency tool built into the memory of Huawei devices. It allows you to download and install the latest official firmware directly from the company's servers, even if the main Android system does not load or does not work correctly. This method is often used when other methods do not work.
To enter this mode, you must turn off your smartphone. Then hold down the Volume Up and Power buttons at the same time. Hold them until the Huawei logo appears, then release the Power button, but continue holding the Volume down until the recovery menu appears. Select Download latest version and recovery.
The system will offer to connect to the Wi-Fi network. Select your network and enter your password. Once connected, eRecovery will contact the server, check the device model and download the full system image. This process may take a long time depending on the Internet speed. Once the download is complete, the phone will automatically begin installation and reboot.
⚠️ Attention: Using eRecovery mode in most cases implies a complete reset of user data (Factory Reset). All photos, contacts and applications will be deleted. Be sure to make a backup before using this method!
It is important to note that this mode only works with official Huawei digital signatures. An attempt to install modified firmware via eRecovery will be blocked. If after updating the phone asks for a Huawei account (FRP lock), you will need to enter the login and password for the account that was synchronized with the device earlier.
What to do if eRecovery gives a download error?
If the download process is interrupted or gives an error, try changing the DNS in the Wi-Fi settings to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare). Sometimes this helps to bypass problems with routing to update servers in your region.
Installation via memory card (dload method)
For advanced users or in situations where there is no Internet connection, there is a manual installation method via a microSD memory card. This method requires first downloading the complete firmware package (usually in the format .zip or an unpacked set of files) from a trusted source to your computer.
In the root of the memory card you need to create a folder named dload (all letters are lowercase). Copy the firmware file inside this folder. Insert the card into the switched off smartphone. Press three buttons at the same time: volume up, volume down and power. Hold them down for about 10 seconds until the update process begins.
This method is called force update. It ignores bootloader version checks and often allows you to install the firmware even if the official update is already closed for your model. However, using files from unverified sources carries a high risk. A mismatch between the region (CUST) or the bootloader version can lead to inoperability of the communication modules.
The dload method is the most powerful installation tool, but requires maximum caution: the firmware file must strictly match the model and region of your device.
After installation is complete, the phone will reboot. The first boot can take up to 5-10 minutes as the system optimizes applications and creates new caches. Don’t panic if the screen remains black with a logo for a long time - this is normal behavior after a deep system update.
Frequent errors and ways to solve them
During the update process, users often encounter various glitches. One common problem is a signature verification error or insufficient space. If the system reports low memory even though you have cleared the phone, try clearing the application cache HiCare or System updates through the app settings before trying again.
Another common situation is “bootloop” after installation. If the phone constantly reboots and does not log into the system, try entering Recovery mode (volume up + power buttons) and follow the step Wipe cache partition. This will delete temporary files of the old system that may conflict with the new one, without affecting your personal data.
- 🔋 Error 15%: Often occurs when the voltage is unstable. Use the original charger and do not use the phone during installation.
- 📶 Error networks: When downloading via eRecovery, change the Wi-Fi frequency from 5 GHz to 2.4 GHz, as recovery mode works better with older communication standards.
- 🔒 Locking the bootloader: If you previously unlocked the bootloader, returning to stock firmware may require re-locking it through computer utilities, otherwise banking applications will not work.
If nothing helps and the phone shows no signs of life, you need to contact an authorized service center. Specialists have access to proprietary firmware tools (for example, Huawei Tool) that can restore the device even if the bootloader is damaged. Independent attempts at resoldering or deep intervention in this case will only aggravate the situation.
⚠️ Attention: Menu interfaces and item names may vary slightly depending on the specific model (P30, Mate 20, Nova 5T) and EMUI version. Always check the visual design of your screen.
Frequently asked questions (FAQ)
Is it possible to upgrade to Android 10 if the phone was purchased in China?
Yes, but with nuances. Chinese versions (CN) receive updates before global versions. However, when changing the region to global (RU/EU), in order to obtain a stable version with Google services (if they are supported by the model), a complete data reset may be required. Make sure that the model supports the required communication frequencies of your operator.
Will the update delete my photos and contacts?
When updating through Settings, HiCare or HiSuite, the data is usually saved. However, if you use eRecovery mode or the dload method with full formatting, all data will be deleted. Always make a backup copy before starting the process, regardless of the chosen method.
Why did the phone run slower after the update?
In the first 1-2 days after installing a major update, the system performs background file indexing and database optimization. This may cause heating and poor performance. Usually the situation stabilizes on its own after a couple of days of active use.
Is it possible to roll back from EMUI 10 to Android 9?
Officially, Huawei prohibits version rollback (Downgrade) for security reasons. You can return to the old version only through a service center using special paid tools, or by completely flashing it with unlocking the bootloader, which will void the warranty.
Will Google services disappear after the update?
On devices released before US sanctions (May 2019), Google services (GMS) are retained and are updated regularly along with the system. On new devices without a Google license, updating to EMUI 10 will not add Google services, since they are not in the base firmware.
