Introduction

Flashing a ZTE phone refers to the process of modifying its firmware, which includes the operating system (OS), recovery image, and other essential components. This procedure is often performed to upgrade the device's software to a newer version, fix software glitches, or install custom ROMs and kernels for enhanced features and customization. This guide will provide a comprehensive tutorial on how to flash a ZTE phone safely and effectively.

Prerequisites
A compatible ZTE phone
USB data cable

Step 1: Enable USB Debugging

Before proceeding with the flashing process, it is crucial to enable USB Debugging on your ZTE phone. To do this:
Go to "Settings" and tap on "System."
Select "Developer Options" and tap on "USB Debugging."
If "Developer Options" is not visible, go to "About Phone" and tap "Build Number" repeatedly until it says "You are now a developer."

Download and install the latest version of ADB (Android Debug Bridge) and Fastboot tools from the Android SDK Platform Tools package. Extract the downloaded ZIP file to a convenient location on your computer.

Step 3: Connect Phone to Computer

Connect your ZTE phone to the computer using a USB data cable. Ensure that your phone is turned on and unlocked.
