Guide to Achieving Full Play Integrity on Custom ROMs

This post provides a detailed guide to achieving full Play Integrity verification (Basic, Device, and Strong) on devices running a Custom ROM. It is common for Custom ROMs not to meet all MEETS_INTEGRITY requirements, which can limit the functionality of certain applications, especially banking apps. This guide is designed to help you overcome these limitations.

1. Prior Considerations and Requirements

• Rooted Device: It is essential that your Android device is rooted.

• Root Manager: The use of KernelSU or KernelSU next is strongly recommended instead of Magisk. Magisk is more prone to detection by applications that verify system integrity, which can cause issues with sensitive services like banking applications.

• Kernel Compatibility: Please note that Custom ROM developers often optimize their ROMs for a specific kernel. Installing a different kernel than the pre-established one could lead to instabilities or operational problems. It is advisable to consult the ROM's support group to verify kernel compatibility and, if necessary, look for a KernelSU version that is compatible with the recommended kernel.

• Integrity Verification: To check your current Play Integrity status, you can install the "INTEGRITY CHECKER".

2. Initial Installation Process

Follow the steps below to set up the necessary modules:

1. Install KernelSU: Download and install the KernelSU or KernelSU Next application.

2. Modules:

   • Open the KernelSU application.

   • Install the [Tricky-Store] module.

   • Install the [YuriKey] module.

   • Install the [Zygisk-Next] module.

3. Reboot Device: Once all modules are installed, reboot your device.

3. Yuri Keybox Manager Config

After rebooting, proceed with the Yuri Keybox configuration:

1. Install KsuWebUI: Install the [KsuWebUI] apk.

2. Access Yuri Keybox Manager: Open the KsuWebUI apk and access the [Yuri Keybox Manager] section.

3. Security Configuration:

   
   Within Yuri Keybox Manager, navigate to "Menu" and select the following options to configure them:

   • Set Up Yuri Keybox

   • Set Up Target.txt

   • Set Up Security Patch

   • Set Up verified Boothash

   • Avoid modifying any other settings in this section.

4. Reboot Device: Exit the KsuWebUI application and reboot your device again.

After these steps, when checking with the INTEGRITY CHECKER, you should observe that your device has passed two of the three integrity verifications.

4. Obtaining the Third Integrity Verification

To achieve the third and final integrity verification, do the following:

1. Install PlayIntegrityFix: Install the [PlayIntegrityFix] module.

2. KsuWebUI Config:

   
   
   

   • Reopen the [KsuWebUI] application.

   • Access the [Play Integrity Fix [INJECT]] section.

   • Click on the "Advanced" option.

     
     
     

   • Select the Spoof Provider and Spoof Build options.

   • Important Note: To ensure the correct functioning of Google Wallet, it is necessary to disable the Spoof Provider option after completing these steps.

With these steps completed, your device should now pass all three Play Integrity verifications, allowing full use of applications that depend on this security feature.
