  • Sufficient Battery: Ensure your device has at least 50% battery to avoid interruptions during the process.

Core Steps for Bypassing Play Integrity with Magisk

1. Enabling Zygisk and Enforcing DenyList

Zygisk allows modules to load code into the Zygote process, providing a powerful way to modify system behavior. The DenyList hides Magisk from specific apps, preventing them from detecting root.

  1. Enable Zygisk: Open Magisk Manager, go to Settings, and enable Zygisk.
  2. Configure the DenyList:
    • Go to the “Configure DenyList” section (usually found right below the Zygisk toggle).
    • Enable the DenyList for Google Play Services, Google Play Store, and any other apps that are failing Play Integrity. Click the three dots next to each app and select “Show System Apps” to find the necessary system processes associated with Play Services. Make sure to select all processes related to Play Services.
    • Consider adding other potentially problematic apps that might detect root.

2. Installing and Configuring the Universal SafetyNet Fix Module

The Universal SafetyNet Fix module is specifically designed to spoof the SafetyNet attestation, which is a precursor to the Play Integrity API.

  1. Download the Module: Obtain the latest version of the Universal SafetyNet Fix module from a reputable source, such as the Magisk Module Repository.
  2. Install the Module:
    • Open Magisk Manager.
    • Tap on “Modules” in the bottom menu.
    • Tap “Install from storage.”
    • Navigate to the downloaded module ZIP file and select it.
    • Magisk will flash the module.
  3. Reboot: After installation, reboot your device.
  4. Verify Installation: After rebooting, check the “Modules” section in Magisk Manager to ensure the module is enabled.

3. Using Shamiko: Hiding Root More Effectively

Shamiko is a Magisk module that enhances root hiding capabilities, making it more difficult for apps to detect root.

  1. Install Shamiko Module: Download Shamiko from a trusted source. Install it in Magisk Manager similarly to the Universal SafetyNet Fix module.
  2. Enable Shamiko: Ensure the module is enabled after installation.
  3. Reboot: Reboot your device after enabling Shamiko.
  4. Configure DenyList again: After installing and enabling Shamiko, revisit the DenyList configuration and ensure all relevant apps are still included. This is important because Shamiko can sometimes change how apps are detected.

4. Implementing MagiskHide Props Config (if necessary)

MagiskHide Props Config allows you to modify system properties to further spoof your device information. This can be helpful if SafetyNet or Play Integrity checks are failing due to incorrect device properties.

  1. Install the Module: Similar to the other modules, download and install MagiskHide Props Config from the Magisk Module Repository.
  2. Open a Terminal Emulator: Use an app like Termux.
  3. Gain Root Access: Type su and grant root permissions.
  4. Run the Module: Type props and press Enter.
  5. Follow the Prompts:
    • The module will present a menu. Choose the option to edit device fingerprint.
    • Select a certified fingerprint that matches your device’s brand (Redmi). You can find lists of certified fingerprints online or use a fingerprint from a device with similar hardware. Choose a fingerprint that corresponds to an Android version close to the one your custom ROM is based on.
    • The module will prompt you to reboot.
  6. Reboot: Reboot your device after applying the fingerprint.

5. Clearing Data and Cache for Google Play Services and Play Store

Sometimes, old data and cache can interfere with Play Integrity checks. Clearing this data can resolve these issues.

  1. Go to Settings: Open your device’s Settings app.
  2. Navigate to Apps: Find the “Apps” or “Application Manager” section.
  3. Find Google Play Services: Locate “Google Play Services” in the list of apps.
  4. Clear Cache and Data:
    • Tap “Storage.”
    • Tap “Clear Cache.”
    • Tap “Clear Data” (this will delete your Play Services data, so you may need to re-login to some Google services).
  5. Repeat for Google Play Store: Follow the same steps for the Google Play Store app.
  6. Reboot: Reboot your device after clearing the data and cache.

6. Re-registering your Device with Google (GMS)

Sometimes, the device registration with Google’s services can become corrupted. Forcing a re-registration can resolve this.

  1. Dial *#*#2432546#*#*: Open your device’s dialer and enter this code. This code triggers a Google Service Framework (GSF) registration.
  2. Tap “Register”: A menu should appear with a “Register” button. Tap it.
  3. Reboot: Reboot your device.

7. Checking and Updating Google Play Services and Google Play Store

Outdated versions of these apps can sometimes cause Play Integrity issues.

  1. Install a Logger Module: Search for “SafetyNet Logger” or “Play Integrity Logger” in the Magisk Module Repository and install one.
  2. Trigger a Check: Open an app that requires Play Integrity to pass.
  3. Collect Logs: The logger module will generate logs that you can access through a file manager or a dedicated app.
  4. Analyze the Logs: Look for error messages or specific failures related to attestation or device properties. This information can help you identify the root cause of the problem.

2. Customizing build.prop Manually (Advanced)

This method is more advanced and requires caution, as incorrect modifications to build.prop can cause boot loops.

  1. Backup build.prop: Before making any changes, create a backup of your build.prop file. You can do this using a file manager with root access or through ADB.
  2. Edit build.prop:
    • Use a text editor with root access to open /system/build.prop.
    • Modify the following properties to match a certified device:
      • ro.product.manufacturer
      • ro.product.model
      • ro.build.fingerprint
      • ro.build.version.release (Android version)
    • Be very careful when editing these values. Ensure they are accurate and correspond to a real, certified device.
  3. Save and Reboot: Save the changes to build.prop and reboot your device.
  4. Verify Changes: After rebooting, use a terminal emulator to check the modified properties using the getprop command (e.g., getprop ro.product.model).

3. Addressing Common Errors and Issues

  • CTS Profile Mismatch: This usually indicates that the device fingerprint is not valid. Try using a different fingerprint or double-check that the fingerprint you’re using is certified for your device.
  • Evaluation Type MISMATCH: This error suggests there is an issue with the SafetyNet attestation. Make sure you have the Universal SafetyNet Fix module installed and properly configured.
  • “Device Not Certified” Error in Google Play Store: Try re-registering your device with Google (GMS) and clearing the data and cache for Google Play Services and Google Play Store.
