SafetyNet Fix Guide: Resolve CTS Profile Mismatch Errors on Rooted Android Devices

Even if your device passes Google’s SafetyNet checks, banking apps or streaming services like Netflix might still refuse to work due to advanced root-detection methods. At MagiskModule, we provide a definitive solution to bypass CTS Profile Mismatch errors and ensure app compatibility using Zygisk modules, Magisk DenyList tweaks, and kernel-level spoofing.

Some of your banking apps might not be working even if you are passing the safety net nowadays.

Understanding CTS Profile Mismatch and Modern Root Detection

A CTS Profile Mismatch occurs when SafetyNet detects:

• Unlocked bootloaders.
• Custom ROMs or modified system partitions.
• Active root access (Magisk, SuperSU).
• Zygisk modules or kernel tweaks.

However, modern apps employ deeper checks beyond basic SafetyNet validation, such as:

• Magisk App Detection: Scanning for the Magisk Manager package.
• Zygisk Module Tracing: Identifying modules like Riru or LSPosed.
• DenyList Bypass: Detecting apps exempted from root hiding.

Below, we outline advanced methods to address these issues.

Prerequisites for Bypassing CTS Profile Mismatch

Before proceeding, ensure your device meets these requirements:

• Magisk v25.0+
• Zygisk Enabled: Navigate to Magisk → Settings → Enable Zygisk.
• Custom Recovery (Optional): TWRP recommended for manual flashing.
• Backup: Safeguard data to avoid bootloops.

Method 1: Shamiko Module – Advanced Root Hiding

Shamiko, developed by the LSPosed team, is a Zygisk module that hides Magisk root, Zygisk, and related modules from apps. Unlike traditional DenyList methods, Shamiko operates stealthily without enabling DenyList Enforcement.

Step 1: Install Shamiko

1. Download Shamiko

2. Flash the Module:

   • Open Magisk → Modules → Install from Storage → Select Shamiko.zip.
   • Tap on ok to install → Reboot your device.

3. Verify Installation:

   • Post-reboot, open Magisk → Modules.
   • Confirm Shamiko appears in the active modules list.

Step 2: Configure DenyList Without Enforcement

1. Add Target Apps to DenyList:

   • Open Magisk → Settings → DenyList.
   • Select apps like Google Play Services, Netflix, or banking apps.

2. Disable DenyList Enforcement:

   • Ensure the “Enforce DenyList” toggle is OFF. Shamiko works without it.

3. Hide Magisk App:

   • In Magisk → Settings → Hide the Magisk App.
   • Rename the app to avoid detection (e.g., “Settings Manager”).

Step 3: Whitelist Mode (Advanced)

For granular control over root access:

1. Create a Whitelist File:

   • Use a root file explorer to create /data/adb/shamiko/whitelist.
   • Leave the file empty → Reboot.

2. Grant Root Access:

   • Only apps previously granted root in Magisk will retain access.
   • To grant new apps root, delete the whitelist file temporarily.

Method 2: Universal SafetyNet Fix + MagiskHide Props Config

For devices failing Basic Integrity or CTS Profile Match:

Step 1: Universal SafetyNet Fix.

2. Flash and Reboot:
   • Install via Magisk Manager → Reboot.

Step 2: Spoof Device Fingerprint

1.Install MagiskHide Props Config.

2. Terminal Configuration:

   • Open Termux → Run:

     su  
     props  
     

   • Select Edit Device Fingerprint → Pick a certified fingerprint → Choose your device model.

3. Reboot and Test:

   • Use YASNAC to confirm SafetyNet passes.

Method 3: Kernel-Level Hiding with HiddenCore Module

For legacy devices (Android 7.0–11), HiddenCore Module masks root at the kernel level:

1. Download HiddenCore Module.

2. Flash via Magisk Manager:

   • Install the ZIP → Reboot.

3. Disable Competing Modules:

   • Turn off MagiskHide or Xposed to prevent conflicts.

Troubleshooting Persistent CTS Profile Mismatch

1. Clear Google Play Services Data

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

2. Disable Hardware Attestation

• Flash Riru-UnsafeKeystore to force basic attestation checks.

3. Check for Modified System Partitions

• Reflash your ROM’s stock boot image if partitions are altered.

4. Use a Signed Custom ROM

• Opt for ROMs with valid signatures (e.g., LineageOS Official).

FAQs: Advanced CTS Profile Mismatch Fixes

Q: Why Do Banking Apps Still Detect Root After Passing SafetyNet?

A: Apps now scan for Magisk Manager, Zygisk, or /data/adb/modules. Use Shamiko and rename Magisk to evade detection.

Q: Can I Use Shamiko with Magisk Delta?

A: No. Shamiko requires official Magisk v24.1+.

Q: Does Shamiko Work on Android 14?

A: Yes, but ensure you’re using Shamiko v0.7.3+.

Conclusion: Restore App Compatibility with Confidence

Bypassing CTS Profile Mismatch errors demands a multi-layered approach, combining Shamiko’s stealth root hiding, Universal SafetyNet Fix, and device fingerprint spoofing. By following this guide, you can ensure banking apps, Google Pay, and streaming services function flawlessly on rooted devices.
