PIF forked to be more futureproof and develop more methodically

A Zygisk module which fixes "ctsProfileMatch" (SafetyNet) and "MEETS_DEVICE_INTEGRITY" (Play Integrity).

To use this module you must have one of the following (latest versions):

• Magisk with Zygisk enabled (and Enforce DenyList enabled if NOT also using Shamiko, for best results)
• KernelSU with Zygisk Next module installed
• APatch with Zygisk Next module installed

It injects a classes.dex file to modify fields in the android.os.Build class. Also, it creates a hook in the native code to modify system properties. These are spoofed only to Google Play Services' DroidGuard (SafetyNet/Play Integrity) service.

The purpose of the module is to avoid hardware attestation.

You can fill out the included template example.pif.json from the module directory (/data/adb/modules/playintegrityfix) then rename it to custom.pif.json to spoof custom values to the GMS unstable process. It will be used instead of any included pif.json (none included currently).

Note this is just a template with the current suggested defaults, but with this fork you can include as few or as many android.os.Build class fields and Android system properties as needed to pass DEVICE verdict now and in the future if the enforced checks by Play Integrity change.

As a general rule you can't use values from recent devices due to them only being allowed with full hardware backed attestation. See the Resources below for information and scripts to help find a working fingerprint.

Older formatted custom.pif.json files from cross-forks and previous releases will be automatically migrated to the latest format. Simply ensure the filename is custom.pif.json and place it in the module directory before upgrading.

A migration may also be performed manually with sh migrate.sh and custom.pif.json in the same directory, or from a file explorer app that supports script execution.

You can customize the included default example.app_replace.list from the module directory (/data/adb/modules/playintegrityfix) then rename it to custom.app_replace.list to systemlessly replace any additional conflicting custom ROM spoof injection app paths to disable them.

Make sure Google Play Services (com.google.android.gms) is NOT on the Magisk DenyList if Enforce DenyList is enabled since this interferes with the module; the module does prevent this using scripts but it only happens once during each reboot.

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

• Disable all modules except this one
• Try a different (ideally known working) custom.pif.json

Note: Some modules which modify system (e.g. Xposed) can trigger DroidGuard detections, as can any which hook GMS processes (e.g. custom fonts).

• Disable Zygisk Next
• Reboot
• Enable Zygisk Next
• Reboot again

• Check the kernel release string with command adb shell uname -r or uname -r
• If it's on the Known Banned Kernel List then inform your kernel developer/ROM maintainer to remove their branding for their next build
• You may also try a different custom kernel, or go back to the default kernel for your ROM, if available/possible

Follow these steps:

• Reflash the module in your root manager app
• Clear Google Wallet (com.google.android.apps.walletnfcrel) and/or Google Pay (com.google.android.apps.nbu.paisa.user) cache, if you have them installed
• Clear Google Play Store (com.android.vending) cache and data
• Clear Google Play Services (com.google.android.gms) cache and data, or, optionally skip clearing data and wait some time (~24h) for it to resolve on its own
• Reboot

Note: Clearing Google Play Services app data will then require you to reset any WearOS devices paired to your device.

You can read module logs using one of these commands directly after boot:

adb shell "logcat | grep 'PIF/'" or su -c "logcat | grep 'PIF/'"

Add a "verboseLogs" entry with a value of "0", "1", "2", "3" or "100" to your custom.pif.json to enable higher logging levels; "100" will dump all Build fields, and all the system properties that DroidGuard is checking. Adding the entry can also be done using the migration script with the sh migrate.sh --force --advanced or sh migrate.sh -f -a command.

No.
