Modern smartphones, such as Honor 20, regularly receive software updates designed to improve stability, close security vulnerabilities and add new features. However, in practice, the situation is often different: after installing a new version EMUI or Magic UI users are faced with increased battery consumption, overheating of the case, or unstable operation of certain applications.
In such cases, the only rational solution is to return to the previous, more stable version of the operating system. The rollback procedure on Honor 20 is not a trivial task, like simply deleting an application, and requires careful preparation, since official methods often involve completely deleting user data.
In this guide, we will analyze in detail all the available methods of downgrading the software version. You will learn how to use the official software from the manufacturer, how to use the hidden functions of the recovery mode, and what risks manual installation of archived firmware packages entails.
Preparation of the device and risk assessment
Before you begin any manipulations with the system memory partition, you need to understand the seriousness of the upcoming actions. Firmware rollback is the process of writing data to protected memory areas, an error in which can lead to the smartphone turning into a “brick.”
The most critical point is the complete loss of personal information. Unlike a regular factory reset, when downgrading (downgrading the version), the system often requires formatting the partition data to prevent database conflicts between the old and new versions of Android.
⚠️ Attention: The process of rolling back the firmware is guaranteed to delete all photos, contacts, messages and installed applications from the internal memory of the device. Creating a backup copy is a mandatory step, without which further actions are pointless.
To work, you will need certain tools and conditions. Make sure the battery is at least 60% charged, as a sudden power outage during flashing will compromise the integrity of the bootloader. You also need a high-quality USB cable, preferably the original one that comes with the device.
Use only the original cable and USB 3.0 port on the computer to ensure stable data transfer speeds and minimize the risk of connection loss.
Download and install the latest version of the official utility on your computer. This app is a key ecosystem tool HiSuite latest version. This app is a key ecosystem tool Huawei/Honor for device management and software recovery.
Official method via HiSuite
The safest and manufacturer-recommended way to return to an old version of software is to use the system restore function in the application HiSuite. This method automatically selects a compatible firmware version and monitors the integrity of installed files.
First, connect your Honor 20 to your computer and run the app. In the main menu of the interface, find the section responsible for updating or restoring. It is usually labeled as “System Restore” or “System Recovery.”
If the automatic search does not offer a rollback, try using a key combination to enter a special mode. Hold down the volume down button and connect the cable to the PC, holding the key until the logo appears Fastboot.
- 📱 Make sure that USB debugging is enabled on your smartphone in the “For Developers” menu.
- 💻 Install the drivers Huawei USB Drivers on your computer in advance.
- 🔌 Do not disconnect the cable until the process is complete and reboot.
- 🔋 The battery charge must be above 50% before starting the procedure.
The “Roll back to previous version” option or a list of firmware available for installation may appear in the app interface. Select the desired package and confirm the action. The system will warn you about erasing data - agree if a backup has already been created.
☑️ Check before rollback via HiSuite
The process may take from 10 to 30 minutes depending on the speed of the USB port and the amount of data being installed. At this time, the smartphone screen may go dark and turn on several times - this is normal behavior when repartitioning memory partitions.
Using Recovery mode and the Dload method
If the software method via a computer does not work or gives an error, you can use the local update method, known as Dload. This method involves manually copying the firmware file to the phone's internal memory and starting the installation through the engineering menu.
To implement this method, you need to find the full firmware package (Full OTA) for your specific model and region. The file usually has an extension .zip and weighs several gigabytes. There is no need to unpack it.
Create a folder named dloadin the root of the internal memory or on the microSD memory card. Place the downloaded archive with the firmware inside this folder. Make sure that the file name does not contain Cyrillic characters or spaces.
⚠️ Attention: Using firmware from another model or another region (for example, firmware for CND-L29 on an L29 phone) may lead to irreversible damage to the bootloader and loss of warranty.
After preparing the files, turn off the smartphone completely. Then hold down three buttons at the same time: volume up, volume down and power button. Hold them until the logo appears Honor and the installation process begins.
What to do if the Dload mode does not start?
If the combination of three buttons does not work, try entering the Recovery menu in the standard way (Volume Up + Power), then select “Boot from SD card” or “Install from storage” if it is available in your menu.
The installation progress bar will appear on the screen. Do not interrupt this process under any circumstances. After completion, the phone will reboot automatically, and the initial system setup will begin with the rolled back version of the software.
Comparison of firmware rollback methods
The choice of a specific method depends on your technical training, the availability of a computer and the condition of the device itself. Each method has its advantages and disadvantages, which should be taken into account before starting work.
The method through HiSuite is preferable for most users, as it minimizes the human factor. The app itself checks the compatibility and integrity of the data, reducing the risk of errors.
The method Dload is more universal, as it allows you to install any firmware version, even one that the manufacturer’s servers no longer officially offer. However, it requires an independent search for files and carries great risks if you choose the wrong version.
| Criteria | HiSuite (PC) | Dload mode (Local) | TWRP (Custom) |
|---|---|---|---|
| Complexity | Low | Medium | High |
| Risk of error | Minimal | Average | High |
| Need a PC | Required | Not required | Desirable |
| Data safety | Full deletion | Full deletion | Save possible |
For the average user, the HiSuite method is the only correct solution that provides a balance between security and results.
Using custom recovery TWRP mentioned in the table for completeness, but on modern devices Honor with a locked bootloader, this method is often not available without complex unlocking procedures, which may be expensive or impossible.
Data recovery after a rollback
After successful completion of the rollback procedure, you will receive the device with factory settings and a clean system. The next step is to restore your digital life from a previously created backup.
If you used a cloud service Huawei Cloud or Google Drive, the restoration process will begin immediately after connecting to Wi-Fi and entering your account. The system will offer to restore contacts, calendar and settings.
To restore photos and documents saved on the computer via HiSuite, connect the phone to the PC again. Launch the app, go to the “Recovery” section and select the desired recovery point from the list.
- 📂 Check the presence of all important files before deleting the backup from your PC.
- 📞 Restore your contact list by synchronizing with your SIM card or account.
- 🔐 Enter passwords from Wi-Fi networks again if they were not saved in the cloud.
- 📲 Reinstall banking applications and reconfigure biometrics.
Please note that some applications may not work correctly immediately after restoration if their database version is incompatible with the rolled back version of Android. In such cases, it is recommended to delete the application and install it again from the store.
⚠️ Attention: app interfaces and menu locations may differ depending on the version of HiSuite and the regional firmware of your device. Always check the prompts on the screen in real time.
Possible problems and solutions
During the rollback process, users may encounter various errors. Understanding the reasons for their occurrence will help you quickly resolve problems without panic.
One of the common problems is a file signature verification error (Signature verification failed). This means that the firmware file was damaged during download or is not suitable for this model. Solution: download the firmware package from another source.
Another common situation is getting stuck on the logo after a reboot. This may indicate a file conflict in the partition data. In this case, you need to enter Recovery mode and perform step Wipe data/factory reset manually.
If the computer does not see the phone in Fastboot or HiSuitemode, try changing the USB port, installing drivers manually through the device manager, or using a different cable. Often the problem lies in the physical connection.
FAQ: Frequently asked questions
Is it possible to roll back Android without losing data?
Officially, no. The security mechanism of Android and EMUI requires the data partition to be cleared when downgrading to avoid errors in the operation of applications and system services. Unofficial methods can save data, but they are extremely risky.
Where can I find the old firmware version for Honor 20?
Official links are often removed from the manufacturer's website. The search should be conducted on specialized forums (for example, w3bsit3-dns.com or XDA Developers), indicating the exact model number (for example, L29, AL00) and the current region.
What to do if the phone does not turn on after a rollback?
Try to perform a “hard reset” by holding the power button for 10-15 seconds. If this does not help, you need to enter Recovery mode and reset the settings (Wipe Data). In the worst case, you will need to flash it via Fastboot mode from a PC.
Does rolling back the firmware affect the warranty?
Using official software and methods (HiSuite, Dload with original files) usually does not void the warranty. However, if the service center finds traces of tampering with system partitions or the installation of modified software, warranty service may be refused.
Is it possible to roll back several versions of Android?
Technically, this is possible if you find the appropriate firmware packages. However, it is not recommended to roll back too far (for example, from Android 10 to Android 9), since old bootloaders may not work correctly with new hardware or screen calibrations.
