Troubleshooting Magisk Root Access Issues on Xiaomi 12 (Cupid)

The Magisk app on your Xiaomi 12 (Cupid) is indicating you're not rooted, despite other apps confirming root access. This can be a frustrating scenario. Let's troubleshoot this common issue and get your device fully rooted.

**Possible Causes:**

* **Magisk Installation Issues:** Perhaps Magisk wasn't installed correctly in the first place. Try reinstalling Magisk using the official Magisk Manager app (ensure you download it from the official source – [https://github.com/topjohnwu/Magisk](https://github.com/topjohnwu/Magisk)).
* **Bootloader Lock:** If your bootloader is locked, it might interfere with Magisk's ability to function properly. You'll need to unlock your bootloader to resolve this. Be aware that unlocking the bootloader will erase your device's data.
* **ROM Compatibility:** Some custom ROMs may have specific requirements or modifications that affect Magisk's root functionality. Consult your ROM's documentation or community forums for information on Magisk compatibility.
* **Insufficient Permissions:** Ensure that Magisk has the necessary permissions to operate correctly. Check your device settings and grant Magisk any required permissions.
* **Corrupted Files:** A corrupted Magisk file or system file can lead to root access problems. Try flashing a fresh copy of Magisk using a trusted recovery tool like TWRP.

**Troubleshooting Steps:**

1. **Double-Check Magisk Installation:** Reinstall Magisk using the official Magisk Manager app, verifying the installation process carefully.
2. **Check Bootloader Status:** Use the command `fastboot oem get_unlock_status` in a terminal to check if your bootloader is locked. If it's locked, unlock it using the instructions provided by Xiaomi or your custom ROM developer. If you are on Xiaomi.eu, your bootloader will already be unlocked.
3. **Review ROM Documentation:** Consult your ROM's documentation or community forums for any specific instructions regarding Magisk compatibility and setup.
4. **Grant Necessary Permissions:** Ensure that Magisk has all the required permissions to operate correctly. You can check and adjust permissions in your device's settings app.
5. **Flash Fresh Magisk Files:** If you suspect corrupted files, download fresh copies of Magisk and related files from the official sources and flash them using a recovery tool.

**Remember:** Rooting your device can void your warranty and potentially make your device more vulnerable to security threats. Proceed with caution and at your own risk.
