Method 1: Reset through the Android settings menu

The simplest and safest method is if the phone turns on and responds to touches. The instructions are suitable for all models ZTE Blade (including Blade A3, Blade A5, Blade V8 etc.), but the location of menu items may vary slightly.

Steps:

1. Open Settings (gear icon on the main screen or in the menu applications).
2. Scroll down and select System → Reset (on some firmware the path: Settings → Advanced → Restore and reset).
3. Tap on Reset settings (or Delete all data).
4. The system will prompt you to enter PIN code or pattern (if installed).
5. Confirm the action by pressing Erase everything or Reset phone.

The process will take 5-15 minutes. Upon completion, the phone will automatically reboot and will offer to configure it as new.

⚠️ Attention: On ZTE Blade with custom firmware (for example, from telecom operators), after the reset you may need to re-activate the SIM card by calling support provider.

Method 2: Reset via Recovery Mode (if the phone does not turn on)

If ZTE Blade stuck on the logo, does not respond to buttons or is blocked - this will help hard reset via recovery mode (Recovery Mode). This method works even without access to the Android system.

Instructions:

1. Turn off the phone (press the power button for 10-15 seconds if it freezes).
2. Hold the combination of buttons:
   • For most models ZTE Blade: Volume up + Power (hold for 10–15 seconds).
   • For ZTE Blade V40/V50: Volume up + Volume down + Power.

If the Recovery menu is in English, and you do not know the language, focus on order of items:

Method 3: Reset using a computer (for advanced users)

If the first two methods did not work (for example, the firmware is damaged), you can use utilities from ZTE or universal tools like ADB (Android Debug Bridge). This method requires a computer and a USB cable.

Step-by-step guide for ADB:

1. Download and install Platform Tools (official tool from Google).
2. Enable on phone USB debugging (Settings → About phone → Build number (tap 7 times) → return to Settings → For developers → Debugging USB).
3. Connect ZTE Blade to the computer and open the command line in the folder with adb.exe.
4. Enter the commands in order:

   adb devices

   (the name of your device should appear)

   adb shell

   su

   (if it asks for root access, allow it on your phone)

   wipe data

   reboot

For models ZTE Blade with a locked bootloader (bootloader) you may need official firmware and utility QFil or ZTE Flash Tool. These tools are difficult for beginners - if you are unsure, contact a service center.

⚠️ Attention: Using unofficial firmware or tools to unlock the bootloader will void the warranty ZTE and may cause permanent damage to the device.

   • 🖼️ Photo/video - copy back from your computer or cloud.
   • 🔑 Passwords - check the saved data in Settings → Google → Google account management → Security → Passwords.
