About module

It injects a classes.dex file to modify few fields in android.os.Build class. Also, in native code it creates a hook to modify system properties. The purpose of the module is to avoid a hardware attestation.

Failing BASIC verdict

If you are failing basicIntegrity (SafetyNet) or MEETS_BASIC_INTEGRITY (Play Integrity) something is wrong in your setup. My recommended steps in order to find the problem:

• Disable all modules except mine.
• Check your SELinux (must be enforced).

Some modules which modify system can trigger DroidGuard detection, never hook GMS processes.

Certify Play Store and fix Google Wallet

Follow this steps:

• Flash my module in Magisk/KernelSU (if you already have my module, just ignore this step).
• Clear Google Wallet cache.
• Clear Google Play Store cache.
• Clear GSF (com.google.android.gsf) cache.
• Clear GMS cache.

Reboot and done!

Read module logs

You can read module logs using this command:

adb shell "logcat | grep 'PIF'"

Can this module pass MEETS_STRONG_INTEGRITY?

No

Play Integrity is now our problem, SafetyNet is deprecated

Make FCM Push back to work after cleared GSF data

Once you cleared GSF (Google Service Framework, com.google.android.gsf) data, a new DeviceID of Google Service Framework will be generated. So all the FCM tokens that have registered in the server of Apps will no longer work (it will point to your old DeviceID). You can follow these steps to make the Apps to generate a new FCM token.

The idea is to delete a file called xxx.gms.appid-no-backup (xxx usually is the package name) in the app's files folder. Once the file does not exist, the app will generate a new FCM token when it starts up next time.

Run the following commands to do that, you can use adb shell, Termux, some terminal apps, or whatever.

1. Get the root user

su

2. cd to /data/data

cd /data/data

3. Search for the files ending with gms.appid-no-backup firstly (without really deleting it), so you can review the list of the files that will be deleted, and make sure it will not delete something wrong (usually it should not. I don't think any other useful files named like this). If you don't really care, you can skip this step.

find . -type f -name '*gms.appid-no-backup'

4. Delete all the files end with gms.appid-no-backup

find . -type f -name '*gms.appid-no-backup' -delete

5. Reboot your device.

6. It is better to launch the apps that receive FCM push one time, to make sure it generates a new FCM token and registers with the server.
