The company's smartphones ZTE, despite the decline in their share in the global market, remain in use by millions of users due to their affordable price and functionality. However, device owners often face the problem of stopping automatic notifications about the release of new versions of the operating system. Updating software is not just a way to get new interface features, but also a critical measure for closing security vulnerabilities and optimizing battery life.
The process of installing new firmware on devices ZTE may vary depending on the model and regional version. While flagship series receive support longer, budget models may require manual user intervention to upgrade to the latest version. Ignoring updates can lead to unstable operation of applications and a decrease in the overall performance of the gadget. Android. Ignoring updates can lead to unstable applications and a decrease in the overall performance of the gadget.
In this article we will analyze in detail all the available methods for upgrading your device: from a standard over-the-air update to a complex flashing procedure via a computer. We will look at the features of the shell MiFavor, the nuances of using the mode Recovery and the tools necessary for the safe installation of system files.
Preparing the device for the update procedure
Before starting any manipulations with the system software, you must perform a number of preparatory steps. Neglecting this stage is the most common reason for turning a smartphone into a “brick.” First of all, make sure that the battery charge level is at least 60-70%. The process of writing data to flash memory is energy-intensive, and a sudden power loss in the middle of the process can damage the bootloader.
The second critical step is saving user data. Even if you plan to upgrade without data loss (OTA), there is always a risk of failure. Back up your contacts, photos and important documents. This can be done through cloud services Google Drive or by copying files to your computer via USB-cable.
⚠️ Attention: If your device has superuser rights (Root), a standard over-the-air update may fail or lead to a cyclic reboot. In such cases, a complete flashing with data clearing is required.
Also check the availability of free space in the internal memory. The update file can be between 1 and 3 GB in size, and additional buffering is required during the unpacking and installation process. If memory is low, delete unnecessary applications or transfer media files to a memory card microSD.
☑️ Checklist before updating
Method 1: Over-the-air (OTA) update
The simplest and safest method of obtaining a new version of the software is using the built-in mechanism OTA (Over-The-Air). This method is intended for ordinary users and does not require special knowledge. The system itself checks the manufacturer's servers for new packages and offers to download them.
To start the scan, go to the settings menu of your smartphone. The path may vary slightly depending on the shell version MiFavor, but usually it looks like this: Settings → About phone → System update. In some older models, the item may be located in the section General settings.
Click the "Check for updates" button. If the server finds a new version that is compatible with your hardware ID, the download will begin. After downloading, the phone will prompt you to reboot and install the patch. The entire process may take from 15 to 40 minutes.
Connect your smartphone to a Wi-Fi network before checking for updates. Downloading firmware via the mobile data can be extremely slow and use up your data plan.
It is important to understand that the manufacturer may distribute updates in waves. Even if a new one has already been released for your model, the notification may not arrive immediately. This is done to reduce the load on the servers and collect statistics about the first installations. Android, the notification may not arrive immediately. This is done to reduce the load on the servers and collect statistics about the first installations.
Method 2: Manual installation via the Recovery menu
If the automatic update does not arrive or fails, you can use the manual installation method. To do this, you will need to find the official firmware file with the extension .zip, intended specifically for your model (for example, ZTE Blade A7 or ZTE Axon). The file must be copied to the root of the internal memory or to a card SD.
After downloading the file, turn off the smartphone completely. Then hold down the key combination to enter recovery mode. On most devices ZTE this is the combination Volume Up + Power. Hold the buttons until the logo appears, then release the power button while continuing to hold the volume.
In the menu Recovery control is carried out with the volume buttons (up/down) and the power button (confirmation). Find item apply update from SD card or apply update from internal storage. Select the previously copied file .zip and confirm the installation.
⚠️ Attention: Do not select the item
wipe data/factory resetif you want to save the data. However, if you are moving between major versions of Android (for example, from 9 to 10), a full reset is often necessary for the system to function correctly.
What to do if Recovery does not see the file?
Make sure that the firmware file has the correct .zip extension and is not renamed. Also check that the file is in the root of memory and not in a folder. Some custom recovery requires that the file be digitally signed by the manufacturer.
After completing the process, which is displayed as a progress bar, select reboot system now. The first launch after manual installation may last longer than usual - up to 5-10 minutes, as the system optimizes applications.
Method 3: Update via computer (USB Update)
For advanced users or in cases where the phone does not boot normally, there is a method of updating via PC. The company ZTE provides special utilities, such as ZTE Update Tool or drivers for the mode QDLoader. This method allows you to restore the device even if the file system is damaged.
You will need to install drivers ZTE USB Drivers on your computer. Without them, the PC will not be able to correctly recognize the phone in a special firmware mode. Download the archive with the firmware for your model and unpack it into a separate folder. Usually inside there is a file with the extension .bin or a launch script.
Run the update utility on your computer. Switch the phone to firmware mode (this is often done by connecting the cable while holding down the volume button). The app should detect the device and begin automatically installing the software.
| Method | Complexity | Risk of data loss | Required equipment |
|---|---|---|---|
| OTA (Over the Air) | Low | No | Wi-Fi network |
| Recovery (SD/Internal memory) | Medium | Possible | Firmware file |
| PC Tool (Via cable) | High | High | PC, Cable, Drivers |
| EDL Mode (Qualcomm) | Expert | Yes (always) | Special. cable/box |
Using a computer is the only way to revive a phone that has stopped turning on after an unsuccessful update, but requires precise selection of the firmware version.
Typical errors and ways to solve them
During the update process, users often encounter technical failures. One common problem is the message "Not enough space" even when there appears to be free memory. This is due to the fact that the system partition has strict limits that do not depend on the total storage capacity.
The solution may be to clear the application cache before updating. Go to Settings → Applications → Show system processes, find the application System Update and clear its cache and data. This will reset temporary files that interfere with correct verification.
Another problem is freezing on the logo ZTE after a reboot. If your phone hangs on screensaver for more than 15 minutes, try to force restart by holding the power button for 10-15 seconds. If this does not help, you will have to go back to Recovery and do a full reset (Wipe Data).
Sometimes the error occurs due to an unstable Internet connection when downloading a file. In this case, the file may be damaged (broken packages). During manual installation, the system will check the checksum of the file and refuse to install it, giving a signature error.
⚠️ Attention: Interfaces and names of menu items may differ depending on the version of the MiFavor shell and regional firmware (Global, Russia, Europe). Always check the official documentation for your specific model.
Frequently asked questions (FAQ)
Is it possible to update ZTE to the latest version of Android if the manufacturer has stopped releasing updates?
Officially, no. If a model is no longer supported, OTA servers will no longer offer new versions. However, enthusiasts often create custom ROMs (for example, LineageOS), which can be installed through an unlocked bootloader and custom recovery (TWRP). This requires advanced skill and will void the warranty.
Will the update erase my photos and contacts?
When updating over the air (OTA) or through the Recovery menu without selecting Wipe Data, user data is saved. However, when moving between major versions of Android (major update), it is strongly recommended to make a backup copy, as the risk of failure is always present.
Why does the phone say “Installation interrupted”?
This often happens if the battery runs out during the process or the user accidentally presses the power button. The reason may also be a damaged firmware file. Try downloading the file again from a reliable source and check its checksum.
Where can I find the official firmware for my ZTE model?
Official files are usually posted on regional ZTE support sites. Also a reliable source is the 4PDA forum, where in topics for specific models, users post stock firmware dumps downloaded from update servers.
Is it safe to interrupt an update if it freezes?
No, this is extremely dangerous. Interrupting recording to the system partition may cause the phone to stop turning on altogether. If the process is frozen for more than an hour, try a forced reboot, but be prepared for the need to reflash via PC.
