Updating the operating system on mobile devices is not just a tribute to fashion or a desire to get new icons. For smartphone owners ASUS this is a critical process that ensures the security of personal data, stable operation of communication modules and optimization of energy consumption. Many users put off installing patches for fear of losing data or encountering errors, but modern firmware methods have become extremely safe and intuitive.
In this article we will analyze in detail all the available methods for installing the new version Android on devices of the ZenFone i ROG Phoneseries. You will learn how to check for updates through the system menu, how to perform a manual installation via a firmware file, and what to do if the automatic search does not bring results. We will also look at the nuances of the transition between major versions of the OS, when the interface changes and new artificial intelligence functions appear.
Before taking active steps, you need to understand what type of update is available for your model. Sometimes the manufacturer releases minor security changes, and sometimes a full change to the system version. Proper preparation of the device ensures that the process will go smoothly, and your smartphone will work faster and smoother.
Preparing the device for the update procedure
Any intervention in the system software requires preliminary preparation. Ignoring this step may cause the process to abort in the middle, leaving the phone inoperable. First of all, make sure that the battery charge is at least 60%, or better yet, connect the device to power throughout the entire process.
The second critical step is to create a backup copy. Even if the update is over the air (OTA), there is always a risk of losing contacts, photos or notes. Use built-in tools Google or a proprietary utility MyASUS to save data to the cloud or external media.
⚠️ Attention: If your device has superuser rights (Root) or the bootloader is unlocked, a standard system update may not install or lead to “bricking” apparatus. In such cases, manual flashing with preliminary locking of the bootloader is required.
⚠️ Attention: The menu interface and item names may vary slightly depending on the version of the ZenUI shell and the specific smartphone model. If you do not find the specified item, check the "About phone" section.
☑️ Ready for update
It is also worth freeing up space in the internal memory. System update files can range from 2 to 5 gigabytes in size and require additional space to unpack and install them. Delete unnecessary application caches or transfer heavy media files to a memory card or computer.
Automatic update over the air (OTA)
The simplest and manufacturer-recommended method is to use the built-in mechanism OTA (Over-The-Air). This method does not require connection to a computer or special technical knowledge. The system itself will check the servers ASUS for the presence of a current build suitable specifically for your region and model.
To start the check, go to the settings menu. Find the section System or About phone. Depending on the firmware version, the update button may be located immediately on the main screen of this section or hidden inside the submenu System update.
Press the button Check for updates. If a new version is found, the system will prompt you to download the package. After downloading, a notification will appear indicating that it is ready for installation. All you have to do is confirm the action, after which the phone will reboot and begin the installation process.
During installation, the screen may go off and on several times. This is normal behavior and indicates a gradual replacement of system partitions. Do not try to interrupt the process or press the volume buttons so as not to violate the integrity of the file system.
OTA update is the safest method, since the system automatically checks the compatibility of the firmware version with your hardware before installation.
Manual installation of the firmware via the ZenUpdate file
Sometimes the automatic search does not find a new one version, although it has already been released for your model. This may be due to regional restrictions or failures in the update servers. In this case, you can download the installation file manually from the official support site ASUS.
The firmware file usually has an extension .zip and a name containing the device model (for example, ASUS_Z00RD_User.zip). The downloaded file must be placed in the root directory of the smartphone’s internal memory. Do not put it in folders with photos or documents; the system should see it immediately when you enter the root of the disk.
After copying the file, go to the system update settings, as described in the previous section. The system will automatically detect the downloaded file and prompt you to update. If automatic detection does not occur, you can use the hidden debug menu or rename the file in accordance with the requirements of a particular model, but most often simply placing it in the root is enough.
What to do if the file is not visible?
Make sure that the file is not unpacked. It should remain a .zip archive. Also check that the file has been downloaded completely and its checksum matches that indicated on the manufacturer’s website. The system will not accept a damaged archive.
This method allows you to update even if there is no stable Wi-Fi connection at the time of installation, since you could download the file itself via a computer or mobile data in advance. This is especially true for large updates, the volume of which exceeds 2-3 GB.
Updating via a computer and the ASUS PC Link utility
For those who prefer to control every step or have problems with a wireless connection, there is a method of updating via a PC. The company ASUS provides special software that allows you to manage your smartphone and update its firmware directly from your computer.
Download and install the utility PC Link or ASUS Sync on your computer. Connect your smartphone to your PC using the original USB cable. Make sure that USB debugging mode is enabled on your phone if the app requires it for deep access to the system.
In the app interface, find the section responsible for managing the device or updating the software. The installation wizard itself will determine the current version of Android and offer a new product available for download. This method often works faster than OTA, since the download speed is limited only by your Internet connection on the computer.
| Update method | Required hardware | Complexity | Risk of data loss |
|---|---|---|---|
| OTA (By air) | Smartphone only | Low | Minimum |
| Manual (ZIP file) | Smartphone + PC/Other phone | Medium | Low |
| Via PC Link | Smartphone + PC + Cable | Medium | Low |
| Recovery Mode | Smartphone + Memory Card | High | Medium |
Using a wired connection also eliminates the risk of losing the connection due to an unstable Wi-Fi signal, which makes this method one of the most reliable for installing major major system updates.
Actions in case of errors and failures
Despite the reliability of modern systems, sometimes the process can fail. Most often, users encounter the message “Failed to install the update” or an endless download. In most cases, the problem lies in lack of space or damage to the update system cache.
Try clearing the cache of the Google Play Services application and the system update section. To do this, go to Settings → Applications → Show system processes. Find the application responsible for the update and click Clear cache. After that, restart the phone and try again.
If the phone is stuck on the logo ASUS after an unsuccessful attempt, you may need to enter Recovery mode Mode). Press and hold the power button and volume up button at the same time until the menu appears. Select item Wipe cache partition. This action is safe and does not delete your personal files, but clears temporary system data that may have caused the conflict.
⚠️ Attention: Item Wipe data/factory reset in the Recovery menu completely deletes all data from the phone. Use it only as a last resort if other methods do not help restore the device's functionality.
If the update constantly gives a download error, try changing the DNS servers in the Wi-Fi settings to public ones from Google (8.8.8.8) or Cloudflare (1.1.1.1). This often solves problems with access to update servers.
System rollback and additional features
Sometimes a new version of Android contains errors or is unstable on a specific model. In such situations, users want to go back to the previous version. Officially ASUS rarely supports direct rollback (Downgrade) through the settings menu for security reasons, since new bootloaders may block the installation of old software.
However, for some models there are special rollback tools available on the support forum or in service centers. The procedure usually requires unlocking the bootloader and completely wiping the device. This is a complex process that is not recommended without good reason and experience.
In addition to security, updates often bring new interface features ZenUI. These could be new control gestures, improved one-handed mode, or camera settings. Regularly checking for updates allows your device to stay up to date longer.
Returning to an older version of Android (rollback) is not possible on all models and often requires complete loss of data, so carefully consider the need for this step.
Is it possible to update Android on ASUS through third-party firmware?
Technically it is perhaps if you unlock the bootloader and install a custom recovery (for example, TWRP). However, this will void the warranty, break the functionality of banking applications (Google Pay will not work without additional tricks) and carry a high risk of breaking the phone. For the average user, this path is not recommended.
Why doesn’t my old ASUS ZenFone receive an update?
Manufacturers support devices with updates for a certain period of time (usually 2-3 years for major versions of Android). If your phone is more than 3-4 years old, it may have reached its official support limit. In this case, the official update will no longer be released.
How long does it take to update the system?
The time depends on the volume of the update and the speed of the phone's memory. Downloading a 1.5 GB package on fast Wi-Fi will take 5-10 minutes. The installation itself and reboot usually last from 10 to 20 minutes. Do not touch the phone during this time.
Do you need to reset the settings to factory settings after the update?
Usually this is not required. The system saves all data and settings. However, if after the update you notice strange behavior, rapid battery drain, or errors in applications, a full reset (Factory Reset) can help eliminate software conflicts between old settings and the new system.
What should you do if there is no sound after the update?
This is a known software glitch that sometimes occurs. Try rebooting your device. If that doesn't help, check your sound effects settings in the sound menu. As a last resort, clearing the cache of the Recovery partition (without deleting data) often solves the driver problem.
