Seamless OTA Updates for Realme 6, 6i (Indian Variant), 6s, and Narzo Series (“nemo”) with Magisk Modules

As dedicated developers and avid users ourselves at Magisk Modules, we understand the frustration of losing root access after applying an Over-The-Air (OTA) update on your Realme device. The Realme 6, 6i (Indian variant), 6s, and Narzo series, codenamed “nemo,” are particularly susceptible to this issue. Fear not! We’ve devised a comprehensive guide to ensure a smooth and persistent root experience even after updating your device.

Understanding the OTA Update Process and Its Impact on Root Access

Over-the-Air (OTA) updates are convenient methods for receiving the latest software improvements, security patches, and features directly from Realme. However, these updates often overwrite critical system partitions, including the boot image where Magisk is installed. This leads to the dreaded unrooted state. The “nemo” devices, like the Realme 6 series, are known for their robust community support, which means many users are actively seeking solutions to maintain root across updates. Our method leverages Magisk modules to circumvent the problems associated with traditional rooting methods, guaranteeing a seamless transition and preventing the loss of root functionality during OTA updates.

Prerequisites: Ensuring a Solid Foundation for OTA Survival

Before embarking on the OTA update journey, it’s crucial to have the following prerequisites in place:

• Realme 6, 6i (Indian Variant), 6s, or Narzo Series Device (“nemo”): This guide specifically targets these devices. Verify your device model before proceeding.
• Unlocked Bootloader: An unlocked bootloader is essential for flashing custom images and modules. Refer to Realme’s official documentation or trusted community guides on how to unlock the bootloader for your specific model (“nemo”). Be aware that unlocking the bootloader will wipe your data.
• Magisk Installed: You must have Magisk already installed and working on your device. If you haven’t rooted your device yet, search for a guide specific to your device model (“nemo”) and install Magisk before proceeding. The version of Magisk should be at least version 20.0 or higher to ensure compatibility with modern patching methods.
• TWRP Recovery (Recommended): While not strictly required, having TWRP recovery installed makes the process significantly easier and provides a safety net in case something goes wrong. It allows for flashing custom ZIP files and performing backups.
• Sufficient Battery Charge: Ensure your device has at least 60% battery charge to prevent interruptions during the update process.
• Backup Your Data: This is paramount. OTA updates, while generally safe, can sometimes encounter unforeseen issues. Back up all your important data, including photos, videos, documents, and contacts, to your computer or a cloud storage service.
• ADB and Fastboot Tools: These are essential tools for communicating with your device in bootloader mode. Ensure you have them properly installed on your computer and that your device is recognized.

Step-by-Step Guide: Performing OTA Updates While Retaining Root Access

This meticulously crafted guide ensures that your Realme 6, 6i (Indian Variant), 6s, or Narzo (“nemo”) device remains rooted after an OTA update.

Step 1: Preparing for the OTA Update

• Disable All Active Magisk Modules: Before initiating the OTA update, it’s prudent to disable all active Magisk modules. Some modules might interfere with the update process and cause boot loops or other issues. You can disable modules within the Magisk Manager app.
• Restore Stock Boot Image (If Needed): If you’ve modified your boot image in any way other than through Magisk (e.g., using a custom kernel), it’s recommended to restore the stock boot image before proceeding. You can find the stock boot image for your device on trusted forums.
• Uninstall Magisk (Optional but Recommended): In Magisk Manager, select “Uninstall” and then choose the “Restore Images” option. This will restore your original boot image. This step ensures the cleanest possible update and reduces the chance of conflicts.

Step 2: Downloading and Installing the OTA Update

• Download the OTA Update: Go to your device’s Settings > Software Update and download the latest OTA update. Do not install it yet.
• Locate the OTA Package: The downloaded OTA package is usually stored in the /data/data/com.android.providers.downloads/cache directory, but the exact location might vary depending on your device and Android version. You will likely need a root file explorer to access this directory. Look for a file with a .zip extension and a name that includes “OTA.”
• Copy the OTA Package: Copy the OTA package to your internal storage or a microSD card for easy access.

Step 3: Patching the Boot Image with Magisk

This is the most crucial step to preserve root access.

• Extract the payload.bin from the OTA Package: The OTA .zip package contains a payload.bin file, which holds the system and boot images. You’ll need a tool like Payload Dumper (available on GitHub) to extract the boot.img from the payload.bin.
• Transfer the Extracted boot.img to Your Device: Copy the boot.img file to your Realme device.
• Patch the boot.img using Magisk Manager: Open Magisk Manager on your device, and tap on “Install.” Choose “Select and Patch a File.” Navigate to the boot.img you transferred and select it. Magisk Manager will patch the boot.img and save it as magisk_patched.img in the Downloads folder.
• Transfer the magisk_patched.img Back to Your Computer: Copy the magisk_patched.img file from your device back to your computer.

Step 4: Flashing the Patched Boot Image

• Reboot Your Device to Fastboot Mode: Power off your device and then press and hold the appropriate button combination (usually Volume Down + Power button) to boot into fastboot mode.

• Flash the Patched Boot Image: Open a command prompt or terminal on your computer and navigate to the directory where you saved the magisk_patched.img file. Execute the following command:

  fastboot flash boot magisk_patched.img
  

• Reboot Your Device: After the flashing process is complete, reboot your device using the following command:

  fastboot reboot
  

Step 5: Completing the OTA Update and Verifying Root

• Install Magisk Manager (If Uninstalled Earlier): If you uninstalled Magisk Manager earlier, install it again by downloading the APK from the official Magisk GitHub repository.
• Verify Root Access: Open Magisk Manager and check if root access is properly installed. You should see the Magisk version and the green checkmark indicating a successful root.
• Re-enable Your Magisk Modules: Re-enable the Magisk modules you disabled earlier.
• Enjoy Your Rooted Device with the Latest Update: You should now have your Realme 6, 6i (Indian Variant), 6s, or Narzo (“nemo”) device running the latest software update with persistent root access.

Troubleshooting Common Issues

Even with careful execution, you might encounter some issues. Here are some common problems and their solutions:

• Boot Loop: If your device gets stuck in a boot loop after flashing the patched boot image, try flashing the stock boot image to recover. You can obtain the stock boot image from your device’s firmware package or from trusted online resources.
• Magisk Not Detected: If Magisk Manager doesn’t detect root access after the update, try re-installing Magisk Manager or flashing the patched boot image again. Ensure that you flashed the correct magisk_patched.img file.
• OTA Update Fails to Install: If the OTA update fails to install, it might be due to modified system partitions or other customizations. Try restoring your device to stock firmware and then attempt the OTA update again.

Alternative Methods for Maintaining Root

While the method described above is the most reliable, here are some alternative approaches:

• Using Magisk Modules for OTA Survival: Some Magisk modules claim to automatically patch the boot image during OTA updates. However, their reliability can vary, and they might not work with all devices or Android versions. We advise caution when using these modules.
• Manual Patching using TWRP (Advanced): Experienced users can manually extract and patch the boot image using TWRP recovery. This method involves more steps but offers greater control over the process.
