Rooting your Android device unlocks a world of customization and advanced features. However, the process can seem daunting, especially for first-timers. This guide provides a step-by-step, detailed approach to rooting your Redmi 12 5G using Magisk, ensuring a systemless root while minimizing the risk of data loss or bricking your device. We will cover essential precautions, detailed instructions, and troubleshooting tips to make your rooting experience smooth and successful. This guide focuses on achieving root access without wiping your data and addressing the specific concerns mentioned in the original user’s query.

1. Understanding the Basics of Rooting and Magisk

Before diving into the technical details, let’s establish a clear understanding of what rooting is and why Magisk is the preferred method for modern Android devices.

What is Rooting? Rooting grants you privileged control (root access) over your Android system. This allows you to modify system files, install custom ROMs, remove bloatware, and much more.
What is Systemless Root? Traditional rooting methods directly modified the system partition, making it difficult to receive official updates and potentially causing instability. Systemless root, pioneered by Magisk, modifies the boot partition instead, leaving the system partition untouched. This allows you to retain the ability to receive over-the-air (OTA) updates and pass SafetyNet attestation (required for some apps like Google Pay).
Why Magisk? Magisk is a powerful and versatile tool that not only provides systemless root but also offers a suite of modules for further customization. It’s also relatively easy to install and manage, making it ideal for beginners. Magisk Modules Repository is a great resource for enhancing your rooted device with custom functionalities.

2. Prerequisites and Essential Preparations

Before proceeding with the rooting process, it’s crucial to gather the necessary tools and take essential precautions to safeguard your device and data.

Unlock Your Bootloader: This is a mandatory step for rooting any Android device. Unlocking the bootloader allows you to flash custom images (like the modified boot image) onto your phone. Be aware that unlocking the bootloader will wipe all data from your phone. If you haven’t already unlocked your bootloader, you must do so before proceeding. Refer to Xiaomi’s official unlocking tool and instructions for the Redmi 12 5G. Magisk Modules can be useful in helping you customize your device once rooted.
Install ADB and Fastboot: ADB (Android Debug Bridge) and Fastboot are command-line tools that allow you to communicate with your Android device from your computer. Download and install the Android SDK Platform Tools from Google’s official developer website. Ensure that ADB and Fastboot are properly configured and added to your system’s PATH environment variable.
Download the Latest Magisk APK: Obtain the latest version of the Magisk APK file from the official GitHub repository or a trusted source. Install the APK on your phone.
Back Up Your Data: Even with systemless root, there’s always a small risk of data loss. Back up all your important data, including contacts, photos, videos, and documents, to your computer, cloud storage (as suggested in the initial query), or an external storage device. This step is non-negotiable.
Charge Your Device: Ensure that your phone has at least 60% battery charge before starting the rooting process. This will prevent unexpected shutdowns during flashing, which could lead to complications.
Gather Stock Firmware for Your Device: Download the stock firmware package for your specific Redmi 12 5G model from a reputable source like Xiaomi’s official website or a trusted firmware repository. This will be your safety net in case anything goes wrong. Extract the boot.img and vbmeta.img files from the firmware package.

3. Verifying vbmeta Integrity (Orange or Green State)

The vbmeta integrity check is crucial for avoiding bootloops after flashing a modified boot image.

Understanding vbmeta: vbmeta contains information about the integrity of the system partitions. If vbmeta verification is enabled, the device will check the signatures of the system partitions during boot. If the signatures don’t match, the device will refuse to boot.
Checking vbmeta State: The vbmeta state (orange or green) typically refers to whether the vbmeta verification is enabled (orange) or disabled (green). On some devices, this state may be indicated by a warning message displayed during boot. The easiest way to determine the state is by observing if a warning message appears during boot, indicating an unlocked bootloader, or if the device boots without any warning.
Flashing a Disabled vbmeta: If vbmeta verification is enabled (indicated by a warning message during boot), you’ll need to flash a modified vbmeta image to disable verification. If vbmeta verification is already disabled (no warning message during boot), you can skip this step. The modified vbmeta image can be created by zeroing out the contents of the original vbmeta image using a hex editor or a similar tool.
Command for flashing vbmeta:
```
fastboot flash vbmeta --disable-verity --disable-verification vbmeta.img
```
Replace “vbmeta.img” with the path to your vbmeta image.

4. Pulling and Patching the Boot Image

This is where the core of the rooting process takes place. We’ll extract the boot image from your phone and patch it using Magisk.

Pulling the Boot Image:
1. Enable USB debugging on your phone (Settings > About phone > Tap “Build number” seven times > Developer options > Enable USB debugging).
2. Connect your phone to your computer via USB.
3. Open a command prompt or terminal window on your computer.
4. Type the following command to ensure your device is recognized:
```
adb devices
```
  You should see your device listed.
5. Type the following command to pull the boot image from your phone:
```
adb pull /dev/block/bootdevice/by-name/boot boot.img
```
  This will copy the boot image to your computer.
Patching the Boot Image with Magisk:
1. Copy the boot.img file to your phone’s internal storage.
2. Open the Magisk app on your phone.
3. Tap the “Install” button next to “Magisk.”
4. Select “Select and Patch a File.”
5. Navigate to the location of the boot.img file and select it.
6. Magisk will patch the boot image and save the modified image as “magisk_patched.img” in the Downloads folder (or a similar location, depending on your Magisk settings).
Copy the Patched Image Back to Your Computer: Connect your phone to your computer and copy the magisk_patched.img file from your phone’s internal storage to your computer.

5. Flashing the Patched Boot Image

This is the critical step that installs Magisk on your device.

Reboot to Fastboot Mode: Turn off your phone completely. Then, press and hold the Power button and Volume Down button simultaneously until the Fastboot mode screen appears.
Flash the Patched Boot Image: Open a command prompt or terminal window on your computer. Navigate to the directory where you saved the magisk_patched.img file. Type the following command:
```
fastboot flash boot magisk_patched.img
```
Replace “magisk_patched.img” with the actual filename of your patched boot image.
Reboot Your Phone: After the flashing process is complete, type the following command to reboot your phone:
```
fastboot reboot
```
Your phone will now reboot. The first boot may take a bit longer than usual.

6. Verifying Root Access and Magisk Installation

After your phone reboots, it’s time to verify that Magisk is properly installed and that you have root access.

Open the Magisk App: Look for the Magisk app icon on your app drawer. Open the app. If Magisk is properly installed, you should see a green checkmark next to “Magisk” and “Installed.”
Verify Root Access: Download and install a root checker app from the Google Play Store. Run the app and follow the instructions to verify root access. The app should confirm that you have root access.
Install Modules (Optional): Once root access is verified, you can explore and install Magisk modules to further customize your device. Use the Magisk Modules Repository to find useful modules.

7. Troubleshooting Common Issues

Rooting can sometimes encounter unforeseen issues. Here are some common problems and their solutions.

Bootloop: If your phone gets stuck in a bootloop after flashing the patched boot image, try flashing the original boot.img file (that you backed up earlier) using Fastboot. This should restore your phone to its previous state. You may also need to flash the vbmeta image to disable verity if you flashed a vbmeta image before.
No Root Access: If the Magisk app shows that Magisk is installed but root checker apps fail to detect root access, try reinstalling the Magisk app or flashing the patched boot image again.
SafetyNet Failure: If you’re unable to pass SafetyNet attestation, try installing the SafetyNet Fix module in Magisk. This module can help to mask the rooted state of your device.
Brick: If after a mistake your phone is completely bricked, you may need to use Xiaomi’s Mi Flash tool to flash the stock ROM, returning your phone to a factory-fresh state. The process is delicate.

8. Maintaining Systemless Root and Updating Magisk

Keeping your Magisk installation up-to-date is crucial for stability and security.

Updating Magisk: The Magisk app will notify you when a new version is available. You can update Magisk directly through the app. In most cases, the app will automatically patch the current boot image before updating, ensuring that you retain root access.
