Updating the operating system on smartphones ZTE is a process that many users put off due to fear of breaking something or not knowing the sequence of actions. Meanwhile, the current version Android not only expands the functionality of the device, but also closes critical security vulnerabilities, improves performance and compatibility with modern applications. In this article, we will analyze all available update methods - from official to alternative ones - and also dwell in detail on preparing the device, possible errors and ways to eliminate them.

It is important to understand that the update procedure may differ depending on the model ZTE (for example, Blade A7, Nubia Z50 or Axon 30), region of sale and version of the current firmware. Some devices receive over-the-air (OTA) updates automatically, others require manual installation via a computer. We'll look at both options, and also tell you what to do if official support for your model has already ended, but you want to install a more recent version Android.

1. Checking the current version of Android and availability of updates

Before you start updating, you need to make sure that a newer firmware version is actually available for your model. You can do this directly in the device settings: ZTE a newer firmware version is indeed available. You can do this directly in the device settings:

  1. Open the menu Settings on your phone.
  2. Go to the section About phone (or System → About phone on new versions).
  3. Find items Version Android and Build number —this is the current firmware.
  4. Tap on System update (or Checking for updates) to search for available updates.

If the system finds the update, follow the instructions on the screen. If the message “No update” or “Device has already been updated” appears, this may mean:

  • 🔄 Your model ZTE is no longer supported by the manufacturer (relevant for devices older than 3-4 years).
  • 🌍 The update has not yet been released for your region (sometimes firmware is released first for China or Europe).
  • 📵 The device has custom firmware installed that blocks OTA updates.
📊 Has your ZTE phone received official updates over the last year?
Yes, regularly
Yes, but only one
No, support has been discontinued
I don’t know, I haven’t checked

To check the support status of your model, visit the official website ZTE or forums like XDA Developers, where enthusiasts often share information about unofficial firmware. Device series Nubia (for example, Nubia Z40 Pro) usually receive updates longer than budget models Blade.

2. Preparing your phone for an update: backing up and charging

Updating the firmware is a process that can lead to data loss if something goes wrong. Therefore, the required step is to create a backup copy of important information. Here's what you need to save:

  • 📱 Contacts (can be synchronized with Google Account or exported to file .vcf).
  • 📷 Photos and videos (copy to your computer or to cloud: Google Photos contacts and media files|Charge your phone to at least 60%|Connect to a stable Wi-Fi|Make sure you have free space (at least 2-3 GB)|Disable antivirus and optimizers Google Photos, Yandex Disk).
  • 📝 Messages and notes (use apps like SMS Backup & Restore).
  • 🎮 Application data (for games - link progress to your account Google Play Games).

Make a backup of contacts and media files|Charge your phone to at least 60%|Connect to a stable Wi-Fi|Make sure you have free space (at least 2-3 GB)|Disable antivirus and optimizers

-->

Also check the battery charge - it should be at least 60-70%If the phone runs out of power during the update, this may lead to brick (inoperative state) of the device. Connect your phone to a charger or use Power Bankif you plan to update without connecting to an outlet.

⚠️ Attention: If your ZTE is installed root access or the bootloader is unlocked (bootloader), the official update may lock the device. In this case, first return the phone to factory settings or use alternative update methods.

3. over the air (OTA)

The simplest and safest method is updating through the settings menu (OTA). It is suitable for most users and does not require special knowledge. Here are step-by-step guide:
