How to Make a Custom Recovery Image on EMUI 7
Creating a custom recovery image for your EMUI 7 device can be a rewarding endeavor, offering you greater control over your device’s software and potentially improving its performance. Whether you’re looking to flash a custom ROM, install a kernel, or simply backup your system, a custom recovery is a crucial tool. In this guide, I’ll walk you through the process step by step, ensuring you have all the information you need to create your custom recovery image.
Understanding the Basics
Before diving into the process, it’s important to understand what a recovery image is and why you might want to create one. A recovery image is a special type of firmware that allows you to access the recovery mode on your device. This mode is separate from the normal operating system and is used for tasks like installing updates, flashing ROMs, and backing up your device.
EMUI 7, the user interface for Huawei and Honor devices, uses a modified version of Android. This means that the process of creating a custom recovery image will differ slightly from the standard Android process. However, the principles remain the same.
Prerequisites
Before you begin, ensure you have the following prerequisites:
- A Huawei or Honor device running EMUI 7
- ADB (Android Debug Bridge) installed on your computer
- USB drivers for your device installed on your computer
- Root access on your device (optional, but recommended)
- Heimdall (for unlocking the bootloader, if necessary)
- Custom recovery image file (e.g., TWRP or CWM)
Make sure to back up all important data on your device before proceeding, as the process may erase all data on your device.
Unlocking the Bootloader
Unlocking the bootloader is a critical step in the process, as it allows you to install a custom recovery image. The process varies depending on your device, but here’s a general outline:
- Enable Developer Options on your device by going to “About phone” and tapping on “Build number” seven times.
- Enable USB debugging by going to “Developer options” and toggling the “USB debugging” option.
- Connect your device to your computer and open a command prompt or terminal window.
- Use the following command to unlock the bootloader:
fastboot oem unlock
This process may vary depending on your device and the manufacturer’s requirements. Be sure to follow the manufacturer’s instructions carefully.
Flashing the Custom Recovery Image
Once your bootloader is unlocked, you can proceed to flash the custom recovery image. Here’s how to do it:
- Download the custom recovery image file (e.g., TWRP or CWM) to your computer.
- Connect your device to your computer and boot it into fastboot mode by holding the volume down and power buttons simultaneously.
- Open a command prompt or terminal window and navigate to the directory containing the custom recovery image file.
- Use the following command to flash the recovery image:
fastboot flash recovery recovery.img
This process may take a few minutes. Once the process is complete, your device should reboot into the custom recovery mode.
Using the Custom Recovery Image
Now that you have a custom recovery image installed, you can use it to perform various tasks, such as:
- Flashing a custom ROM
- Installing a kernel
- Backing up your device
- Restoring your device
Each of these tasks has its own set of instructions, which you can find in various online forums and guides.
Conclusion
Creating a custom recovery image for your EMUI 7 device can be a challenging but rewarding process. By following the steps outlined in this guide, you can unlock the full potential of your device and take advantage of the many benefits that a custom recovery image offers. Remember to proceed with caution and always back up your data before making any significant changes to your device.
