Potential Data Loss: Installing a custom ROM requires unlocking your bootloader, which will erase all data on your device. Back up your data before proceeding.
Warranty Void: Installing a custom ROM may void your device’s warranty.

Prerequisites for Installing HyperOS 3 on Redmi Note 9 Pro

Before you begin the installation process, ensure you have the following:

Redmi Note 9 Pro: This guide is specifically for the Redmi Note 9 Pro (codename: curtana). Do not attempt to install this ROM on other devices.
Unlocked Bootloader: Your device’s bootloader must be unlocked. Unlocking the bootloader will erase all data on your device, so back up your data before proceeding. Xiaomi provides an official tool for unlocking bootloaders, but the process may take several days.
TWRP Recovery: You’ll need to install TWRP (Team Win Recovery Project) custom recovery on your device. TWRP allows you to flash custom ROMs, kernels, and other mods.
HyperOS 3 ROM: Download the HyperOS 3 ROM for the Redmi Note 9 Pro from a reliable source. Ensure that the ROM is specifically designed for your device.
GCam Mod (Optional): If you plan to use the camera extensively, download a compatible GCam mod (e.g., Shamim’s GCam) to address potential video playback issues.
Magisk (Optional): If you want to root your device, download the latest Magisk APK from the official Magisk website.
USB Cable: A USB cable to connect your device to your computer.
ADB and Fastboot Drivers: Ensure that ADB (Android Debug Bridge) and Fastboot drivers are installed on your computer. These drivers are essential for communicating with your device in bootloader mode.
Backup Your Data: This is extremely important. Unlocking the bootloader and flashing a custom ROM will erase all data on your device. Back up your important files, photos, videos, and contacts to a safe location.
Charge Your Battery: Make sure your device is charged to at least 50% before proceeding with the installation process. This will prevent your device from turning off during the installation, which could lead to complications.
