Bypass SafetyNet Issue: Resolving CTS Profile Mismatch Errors on Rooted Android Devices

Unlocking unmatched customizing by rooting an Android device often results in SafetyNet failures, which causes app incompatibility with services as Google Pay, banking apps or Netflix. Among the most often occurring mistakes is the CTS Profile Mismatch, which marks your device as “untrusted”. Using Magisk modules, we offer a clear method to avoid SafetyNet and fix CTS Profile Mismatch problems at MagiskModule, therefore guaranteeing your device stays both powerful and functional.

Understanding SafetyNet and CTS Profile Mismatch

Google’s anti-tampering mechanism, SafetyNet confirms device integrity. It makes two important checks:

Basic Integrity: Confirms the device isn’t rooted or running custom software.
CTS (Compatibility Test Suite) Profile Match: Ensures the device’s software matches a Google-certified Android build.

A CTS Profile Mismatch occurs when SafetyNet detects:

Custom ROMs or modified system partitions.
Unlocked bootloaders.
Active root access (Magisk, SuperSU).
Kernel-level tweaks or incompatible firmware.

This mismatch blocks apps reliant on Google’s security standards. Below, we outline proven methods to bypass these restrictions.

Requirements for Bypassing SafetyNet

Magisk v25.0+.
Universal SafetyNet Fix.
SafetyNet Spoofer.
Custom Recovery: TWRP or OrangeFox.
Backup: Safeguard data in case of unexpected issues.

Method 1: Universal SafetyNet Fix (Recommended)

Created from kdrag0n and kept up by Displax, the Universal SafetyNet Fix. The most dependable module to get across CTS Profile Mismatch.

Step-by-Step Installation Guide

Download the Module:
- Universal SafetyNet Fix.
Install via Magisk Manager:
- Open Magisk → Modules → Tap Install from Storage.
- Select the downloaded ZIP and swipe to install.
- Reboot your device.
Verify SafetyNet Status:
- Open Magisk → Settings → MagiskHide (if available).
- Use apps like YASNAC or SafetyNet Test to confirm Basic Integrity and CTS Profile Match pass.

Troubleshooting Failed Installations

Bootloop Risks: If the device fails to boot, reflash Magisk via TWRP.
Incorrect Magisk Version: Ensure Magisk is updated to v25.0+.
Conflicting Modules: Disable other modules (e.g., Xposed) before installation.

Method 2: Advanced Spoofing with MagiskHide Props Config

For persistent CTS mismatches, combine Universal SafetyNet Fix with MagiskHide Props Config to spoof your device’s fingerprint.

Install MagiskHide Props Config:
- MagiskHide Props Config.
Terminal Configuration:
- Open a terminal app (Termux) and type:
```
su  
props  
```
- Select Edit Device Fingerprint → Pick a certified fingerprint → Choose your device model.
Reboot and Test:
- SafetyNet checks should now pass.

Method 3: HiddenCore Module for Legacy Devices

Older devices (Android 7.0–9.0) may benefit from HiddenCore Module, which masks root at the kernel level.

Download HiddenCore:
- HiddenCore Module.
Flash via TWRP:
- Boot to recovery → Install → Select ZIP → Swipe to flash.
Configure DenyList:
- In Magisk, add target apps (e.g., Google Play Services, banking apps) to DenyList.

Fixing CTS Mismatch on Custom ROMs

Custom ROM users often face CTS issues due to unofficial build signatures. Follow these steps:

Use a Signed ROM: Opt for ROMs with valid signatures (e.g., LineageOS with MicroG).
Edit Build.Prop:
- Modify /system/build.prop to match a certified device’s values using a root file explorer.
SafetyNet API Spoofing: Enable MagiskHide and Zygisk in Magisk settings.

Troubleshooting Persistent SafetyNet Failures

If errors persist, consider these advanced fixes:

Enable Zygisk and Enforce DenyList

In Magisk → Settings → Enable Zygisk and Enforce DenyList.

Disable Hardware Attestation

SafetyNet may use hardware-backed checks on newer devices. Use modules like Riru-UnsafeKeystore to force basic attestation.

Clear Google Play Services Data

Navigate to Settings → Apps → Google Play Services → Storage → Clear Data.

FAQs: Addressing Common CTS Profile Mismatch Queries

Q: Why does CTS Profile Mismatch occur after OTA updates?

A: Over-the-air updates often reset bootloader states or modify system partitions. Reflash Magisk and SafetyNet modules post-update.

Q: Can I pass SafetyNet without Magisk?

A: Yes, using kernels with built-in hiding (e.g., KernelSU), but Magisk offers greater flexibility.

Q: Is Universal SafetyNet Fix compatible with Android 14?

A: Yes, but use v2.4.0+ for Android 14 Beta support.

Conclusion: Restore App Compatibility with Confidence
