Rooting your device will void the warranty and may cause potential risks if not done properly. Ensure you back up all your data before proceeding and follow the steps carefully.

Prerequisites

Before you begin the rooting and flashing process, here are some things you'll need:

  1. Unlocked Bootloader: Necessary for rooting and flashing custom ROMs.
  2. Custom Recovery (TWRP): You'll need TWRP installed for flashing.
  3. Magisk for Rooting: A tool to root your device.
  4. Custom ROM: Choose the custom ROM you want to install (e.g., LineageOS, Pixel Experience).
  5. ADB & Fastboot Tools: Essential for unlocking the bootloader and flashing ROMs.
  6. USB Cable & PC: You'll need these to connect your phone.
  7. Backup Data: Flashing a ROM will erase your data, so make sure everything is backed up.

Step 1: Unlock the Bootloader

The first step in rooting the iQOO 12 Pro is unlocking the bootloader. This is a critical step that allows system modifications.

1.1 Enable Developer Mode

  • Open Settings > About Phone and tap the Build Number seven times to enable Developer Mode.
  • Go to Settings > Developer Options and enable OEM Unlocking and USB Debugging.

1.2 Enter Fastboot Mode

  • Power off your iQOO 12 Pro.
  • Hold Volume Up + Power together to enter Fastboot Mode.
  • Connect your device to the computer via USB.

1.3 Unlock the Bootloader

  • On your PC, navigate to where you have ADB and Fastboot tools installed.
  • Open a command prompt or terminal.
  • Enter this command to check the device connection:
    fastboot devices
  • To unlock the bootloader, type the following:
    fastboot oem unlock
  • Use the volume buttons on your phone to highlight the option to unlock the bootloader and confirm with the power button.

Unlocking the bootloader will erase all the data on your device, so your phone will reboot and reset after this.

Step 2: Install TWRP Custom Recovery

After unlocking the bootloader, you need to install a custom recovery like TWRP.

2.1 Download TWRP for iQOO 12 Pro

  • Head to the official TWRP website and download the TWRP image file for iQOO 12 Pro.

2.2 Flash TWRP

  • Reboot your phone into Fastboot Mode again by turning it off and holding Volume Up + Power.

  • On your PC, open the command prompt/terminal and navigate to the folder containing the TWRP file.

  • Flash the recovery using this command:

    fastboot flash recovery twrp.img

    (Replace twrp.img with the correct TWRP image filename.)

  • Once TWRP is installed, reboot into recovery mode using:

    fastboot reboot recovery

Now, your iQOO 12 Pro should boot into TWRP.

Step 3: Root the iQOO 12 Pro with Magisk

Rooting your device gives you superuser access and the ability to modify system files. Magisk is the preferred tool for this.

3.1 Download Magisk

  • Download the latest Magisk ZIP file and transfer it to your device’s storage.

3.2 Flash Magisk with TWRP

  1. In TWRP, select the Install option.
  2. Locate the Magisk ZIP file on your phone and select it.
  3. Swipe to confirm the flash.
  4. Once the installation is complete, select Reboot System.

Your iQOO 12 Pro will now reboot, and you will have root access. To verify root, download and install Magisk Manager from the official source.

Step 4: Install a Custom ROM

Once your phone is rooted and has TWRP installed, you can proceed to install a custom ROM for enhanced features and performance.

4.1 Download a Custom ROM

  • Download the custom ROM you want to install on your iQOO 12 Pro, such as LineageOS, HavocOS, or Pixel Experience.
  • Transfer the ROM file to your phone’s storage.

4.2 Boot into TWRP Recovery

  • Power off your phone and hold Volume Up + Power to boot into TWRP recovery.

4.3 Wipe Existing System

  • In TWRP, go to Wipe > Advanced Wipe.
  • Select System, Data, Cache, and Dalvik/ART Cache.
  • Swipe to confirm.

4.4 Flash the Custom ROM

  1. Return to the TWRP main screen and select Install.
  2. Locate the custom ROM ZIP file and select it.
  3. Swipe to confirm the installation.
  4. Once done, reboot your phone.

Your device will boot into the custom ROM you installed. The first boot may take several minutes, so be patient.

Step 5: Install GApps (Google Apps)

If the custom ROM you flashed doesn’t include Google apps, you’ll need to flash GApps to get access to the Play Store, Gmail, and other Google services.

  1. Download the correct GApps package for your custom ROM (based on the Android version).
  2. Boot into TWRP again and select Install.
  3. Locate the GApps ZIP file and flash it the same way you flashed the custom ROM.
  4. Reboot your phone.

Now your device will boot into the new custom ROM with Google apps available.

Post-Rooting and Custom ROM Setup

Once your iQOO 12 Pro is rooted and running a custom ROM, you have the freedom to tweak and modify your device.

  • Install Custom Modules: Use Magisk Manager to install modules that add functionality to your phone.
  • Remove Bloatware: With root access, you can remove pre-installed apps you don’t need.
  • Performance Tweaks: You can modify kernel settings to enhance performance and battery life.
  • Customize UI: Many custom ROMs allow for deep customization of the user interface, gestures, and other features.

Benefits of Rooting and Custom ROM Installation

  1. Complete Customization: Rooting and custom ROMs allow you to personalize every aspect of your phone.
  2. Better Performance: Custom ROMs can offer better optimization, removing bloatware and improving system performance.
  3. Advanced Control: Rooting gives you full control over your device, from advanced backups to firewall protection.
  4. New Features: Custom ROMs often introduce new features not found in stock firmware.
  5. Extended Device Lifespan: Even after official support ends, you can continue using your phone with up-to-date custom ROMs.

Conclusion

Rooting and installing a custom ROM on the iQOO 12 Pro opens up a world of customization and performance enhancements. Whether you're looking to improve battery life, get rid of bloatware, or try out new features, this process gives you the freedom to make your device truly yours. Just remember to proceed with caution, back up your data, and follow the steps carefully.
