Rooting your OnePlus 12R can unlock a world of customization, allowing you to enhance performance, install custom ROMs, and access features not available on a stock device. However, rooting comes with risks like voiding warranties and potential security issues. Follow these instructions carefully to avoid bricking your device.
Why Root Your OnePlus 12R?
Rooting grants administrative access to your device’s operating system, enabling you to:
Install third-party apps requiring root permissions.
Customize the UI with tools like AdAway or Viper4Android.
Improve performance by tweaking system settings.
Install custom ROMs for a tailored Android experience.
However, rooting may void your warranty, break apps like Netflix (due to Widevine L3 downgrade), and risk data loss. Always back up your data before proceeding.
Prerequisites for Rooting OnePlus 12R
Before starting, ensure you have:
A OnePlus 12R with at least 60% battery.
A Windows, Mac, or Linux PC with a USB cable.
Enabled Developer Options: Go to Settings > About Phone > Build Number and tap seven times.
Enabled OEM Unlocking and USB Debugging: Settings > Developer Options.
A full backup of your data, as unlocking the bootloader wipes your device.
Downloaded tools: Android Platform Tools (ADB and Fastboot), Magisk ZIP (latest version), and OnePlus USB drivers.
Step-by-Step Guide to Root OnePlus 12R
Step 1: Unlock the Bootloader
Unlocking the bootloader is the first step, but it will erase all data on your device.
Install ADB and Fastboot: Download Android Platform Tools from Google’s official site and extract them to a folder on your PC.
Connect Your Device: Enable USB Debugging, connect your OnePlus 12R to your PC, and open a command prompt or terminal in the Platform Tools folder.
Check Device Connection: Type adb devices to confirm your device is recognized.
Enter Bootloader Mode: Run adb reboot bootloader. Your device will restart in Fastboot mode.
Unlock Bootloader: Type fastboot flashing unlock. Use the volume keys to select “Unlock the Bootloader” on your device and press the power button to confirm. Your device will wipe and reboot.
Step 2: Download Firmware and Extract Init_Boot Image
To root with Magisk, you need the init_boot.img file from your device’s firmware.
Find Your Firmware Version: Go to Settings > About Phone > Version and note your firmware version.
Download Firmware: Use a trusted source like Oxygen Updater or OnePlus’s official site to download the full firmware ZIP matching your device’s version.
Extract Init_Boot Image: Use a payload dumper tool (available on GitHub) to extract init_boot.img from the firmware ZIP. Alternatively, check XDA forums for pre-extracted images specific to the OnePlus 12R.
Step 3: Install Magisk
Magisk is a systemless root method that preserves your device’s integrity for most apps.
Transfer Magisk: Download the latest Magisk APK from its official GitHub page and install it on your OnePlus 12R.
Patch Init_Boot Image: Transfer the init_boot.img to your phone. Open the Magisk app, select “Install,” choose “Select and Patch a File,” and select init_boot.img. Magisk will create a patched image (e.g., magisk_patched_init_boot.img).
Move Patched Image to PC: Transfer the patched image back to your PC’s Platform Tools folder.
Step 4: Flash the Patched Image
Reboot to Bootloader: Run adb reboot bootloader again.
Flash Patched Image: Type fastboot flash init_boot magisk_patched_init_boot.img. Ensure the file name matches your patched image.
Reboot Device: Run fastboot reboot. Your device should now boot with root access.
Step 5: Verify Root Access
Install Root Checker: Download a Root Checker app from the Google Play Store.
Verify Root: Open the app and tap “Verify Root” to confirm successful rooting.
Step 6: Bypass SafetyNet/Play Integrity (Optional)
Rooting may break apps like Netflix or banking apps due to SafetyNet or Play Integrity checks. To fix this:
Enable Magisk Hide: Open Magisk, go to Settings > Magisk Hide, and select apps to hide root from.
Install Universal SafetyNet Fix: Download this module from GitHub, flash it via Magisk, and reboot.
Clear App Data: Clear data for affected apps (e.g., Netflix) to restore functionality.
Risks and Considerations
Warranty Void: Unlocking the bootloader voids your warranty.
Security Risks: Rooting exposes your device to potential malware if you install untrusted apps.
App Compatibility: Some apps (e.g., banking apps) may not work unless you bypass SafetyNet.
OTA Updates: Rooted devices may require manual firmware updates instead of automatic OTAs.
Unrooting Your OnePlus 12R
If you want to unroot:
Open the Magisk app, tap “Uninstall Magisk,” and select “Complete Uninstall.”
Reboot your device to remove root access.
To lock the bootloader, boot into Fastboot mode and run fastboot oem lock. Note: This will wipe your device again.
Conclusion
Rooting your OnePlus 12R opens up endless possibilities for customization but requires caution. Follow this guide to safely root and unroot your device, verify root status, and bypass app restrictions. For the latest firmware or community support, check XDA Forums or the OnePlus Community.
