How to Reach Device Integrity on MIUI 13 EU ROM (A12)

Understanding Device Integrity on MIUI 13 EU ROM (A12)

Device integrity is a crucial aspect for Android users who want to ensure their device is secure, unmodified, and trusted by apps requiring SafetyNet attestation. On MIUI 13 EU ROM (A12), achieving device integrity can be challenging due to Xiaomi’s aggressive security measures and the inherent nature of custom ROMs. Whether you’re aiming for basic integrity, device integrity, or the coveted strong integrity, the process involves a combination of Magisk modules, system modifications, and careful configuration.

Prerequisites for Achieving Device Integrity

Before diving into the steps, ensure you have the following:

• A rooted MIUI 13 EU ROM (A12) device with Magisk installed.
• A valid keybox from a device with strong integrity (e.g., Yuri’s keybox).
• Magisk modules such as MagiskHide Props Config, Universal SafetyNet Fix, and Lokie’s SafetyNet Fix.
• A custom kernel that supports FUSE (Filesystem in Userspace) and seccomp filters.
• TWRP or another custom recovery for flashing modules and backups.

Step-by-Step Guide to Achieving Device Integrity

1. Install and Configure Magisk Modules

MagiskHide Props Config

This module allows you to spoof device properties to match a device with strong integrity. Install it via the Magisk Manager and configure the following:

• Device fingerprint: Set it to a device known for strong integrity (e.g., Pixel 6).
• Security patch level: Ensure it matches the latest available patch.
• Bootloader state: Set it to “locked” to mimic a stock device.

Universal SafetyNet Fix

This module bypasses SafetyNet checks by modifying system files. Install it and ensure it’s active in Magisk.

Lokie’s SafetyNet Fix

This module provides additional fixes for SafetyNet attestation. Install it and configure it to work alongside other modules.

2. Flash a Custom Kernel

A custom kernel with FUSE support and seccomp filters is essential for bypassing Xiaomi’s security checks. Look for kernels specifically designed for MIUI 13 EU ROM (A12) that are known to work with device integrity.

3. Use a Valid Keybox

A valid keybox is critical for achieving strong integrity. Flash Yuri’s keybox or another trusted source using a custom recovery. Ensure the keybox matches the device fingerprint you’ve set in MagiskHide Props Config.

4. Configure Magisk Manager

Open Magisk Manager and:

• Hide Magisk from system apps and root detection tools.
• Enable MagiskHide and add apps that require device integrity (e.g., banking apps, Google Pay).
• Disable any unnecessary modules that might interfere with integrity checks.

5. Test Device Integrity

Use the Google SafetyNet Test app or Tricky Test to verify your device’s integrity status. If you encounter issues, revisit the steps above and ensure all configurations are correct.

Troubleshooting Common Issues

1. Only Basic Integrity Achieved

If you’re only achieving basic integrity, it could be due to:

• Incorrect device fingerprint: Double-check the fingerprint in MagiskHide Props Config.
• Invalid keybox: Ensure the keybox is valid and matches the device fingerprint.
• Kernel issues: Switch to a different custom kernel with better FUSE support.

2. No Integrity at All

If you’re getting no integrity, it could be due to:

• Conflicting modules: Disable all modules and enable them one by one to identify the culprit.
• Root detection: Ensure MagiskHide is properly configured and active.
• System modifications: Revert any system changes that might interfere with integrity checks.

3. SafetyNet Fails After Reboot

If SafetyNet fails after a reboot, it could be due to:

• Magisk modules not loading: Check the Magisk log for errors.
• Fingerprint reset: Reapply the device fingerprint in MagiskHide Props Config.
• Kernel issues: Ensure the custom kernel is properly installed and configured.

Advanced Tips for Maintaining Device Integrity

1. Regularly Update Magisk Modules

Keep your Magisk modules updated to ensure compatibility with the latest MIUI 13 EU ROM (A12) updates.

2. Backup Your Configuration

Always backup your MagiskHide Props Config settings and keybox before making changes. This ensures you can quickly restore your configuration if something goes wrong.

3. Avoid System Updates

MIUI updates can break device integrity. If an update is available, wait for the community to confirm compatibility before updating.

4. Use a Trusted Source for Keybox

Always use a valid keybox from a trusted source like Yuri. Using an invalid keybox can result in no integrity or even bootloops.

Conclusion

Achieving device integrity on MIUI 13 EU ROM (A12) requires a combination of Magisk modules, custom kernels, and valid keyboxes. By following the steps outlined in this guide, you can ensure your device passes SafetyNet attestation and maintains strong integrity. Remember to regularly update your modules, backup your configuration, and avoid system updates that might break your setup.
