Step 1: Download Your Firmware

To ensure compatibility, download the exact firmware version your phone is currently running.

1. Go to Settings > About phone and note the full OS version (e.g. OS2.0.215.0.WNNMIXM). The letters before XM show the region.
2. Download the Fastboot ROM for exactly the same build and region your phone runs. The 14T Pro (Global/EEA) and the K70 Ultra (China) have different firmware, and using the other phone’s image can cause a bootloop.
3. Extract the downloaded .tgz Fastboot ROM (you may need to extract twice).

Step 2: Extract init_boot.img from Firmware

Step 3: Patch init_boot.img Using Magisk

1. Download and install the latest Magisk (v31.1 at the time of writing) from the official Magisk GitHub releases.
2. Open Magisk, tap Install, choose Patch firmware / image, then Select from storage. Patch the image on the same phone you will flash it to.
3. Locate and select the init_boot.img file.
4. Wait for Magisk to patch the file. It saves magisk_patched-[version]_[random].img in your Download folder. Copy it to the PC with adb pull /sdcard/Download/magisk_patched-…img.
5. Copy the patched file back to your computer.

2. Press and hold the Power + Volume Down buttons simultaneously until the Fastboot logo appears.
3. Connect your phone to your PC via a USB cable.

Step 5: Flash init_boot.img Using Fastboot

1. Copy the patched init_boot.img file to the ADB platform-tools folder on your computer.
2. Open Command Prompt (Windows) or Terminal (Mac/Linux) and navigate to the ADB folder: cd C:\platform-tools\
3. Verify that Fastboot detects your device by running: fastboot devices . If your device appears in the list, you can proceed. If not, check your drivers and USB connection.
4. …executing fastboot flash init_boot magisk_patched-[version]_[random].img (use your file’s exact name). Never flash it to the boot partition.
5. Reboot your phone by running: fastboot reboot

---

Step 6: Verify Root Access

1. Once your phone boots up, open Magisk to ensure installation was successful.
2. Open the Magisk app. If it asks for additional setup (environment fix), accept and let it reboot.
3. Open Magisk: the Magisk card shows the installed version when root works.

Troubleshooting Common Issues

Device Not Recognized in Fastboot Mode

• Install Google’s platform-tools and the USB driver bundled with Mi Unlock, then reconnect.
• Install or update Xiaomi USB drivers.
• Use a different USB port or cable.

Bootloop or Stuck on Logo

• Boot into Fastboot Mode and reflash the original init_boot.img from your firmware.
• If it still doesn’t boot, re-flash the original init_boot.img from the same firmware build (fastboot flash init_boot init_boot.img), then repeat patching on this phone with the latest Magisk. Never use a patched image shared by someone else.

Magisk Not Installed Properly

• Make sure you patched with the latest Magisk, on this same phone.
• Try re-patching and re-flashing init_boot.img.
