HELP REZYGISK ALMOST BRICKED MY PHONE TOO AFRAID TO TRY ZYGISK NEXT

[HELP] ReZygisk Almost Bricked My Phone, Too Afraid to Try Zygisk Next

We understand the frustration and anxiety that comes when a modification to your Android device results in a near-bricking event. The experience of a prolonged boot sequence culminating in a black screen is a scenario that every advanced Android enthusiast dreads. When this happens while attempting to replace core root hiding modules like Zygisk, the hesitation to try alternatives like Zygisk Next is entirely justified. This comprehensive guide is designed to dissect the issue, provide robust recovery methods, and offer a stable path forward for users of the OnePlus 8 (IN2013) running crDroid 10.4 who are battling detection from banking applications like Crédit Mutuel and identity apps like France Identité.

Understanding the “Black Screen of Death” with ReZygisk

The specific issue where a phone hangs on the boot animation or presents a black screen after installing a module like ReZygisk is rarely caused by the module itself being malicious. Instead, it is usually a result of a conflict with the existing Zygisk implementation, the Magisk environment, or the device’s specific kernel configuration.

The Role of Zygisk in the Boot Process

Zygisk is the framework within Magisk that injects code into the zygote process, which is the parent process for all Android apps. When you install a module that modifies this behavior—such as ReZygisk or Zygisk Next—it attempts to unload the default Zygisk and replace it with its own implementation. If there is a mismatch in the systemless mount points or a conflict with the kernel’s init.rc scripts, the system can fail to mount the necessary partitions, resulting in the UI failing to launch.

Device-Specific Factors: OnePlus 8 and crDroid

The OnePlus 8 (IN2013) is a robust device, but running a custom ROM like crDroid 10.4 introduces variables that are not present in stock OxygenOS. Custom ROMs often have specific security patches or SELinux policies that may interfere with modules relying on specific Zygisk hooks. The “black screen” suggests that the surfaceflinger (the service responsible for the UI) is starting, but the zygote process is likely crashing repeatedly in the background, preventing the launcher from initializing.

Emergency Recovery: Regaining Access to Your Device

Before attempting to install any new modules, we must first recover the device from its current state. Since the UI is dead, we must rely on command-line access.

Accessing the Magisk Emergency Shell

When a device boots but the UI is unresponsive, Magisk’s built-in “Emergency Shell” is often accessible.

  1. Connect your OnePlus 8 to a PC via USB cable.
  2. Open a terminal or command prompt on your computer.
  3. Type adb shell.
  4. If the device is recognized (check with adb devices), you are in the shell.
  5. However, if the device is in a “black screen” state, the USB debugging authorization may not persist. In this case, the most reliable method is the Key Combination.

The Key Combination Method: Many custom ROMs allow access to the Magisk Emergency Shell by holding specific keys during the boot process or after the screen goes black.

  1. Force restart the device (Hold Power + Volume Up).
  2. Wait for the boot animation to start.
  3. Immediately after the boot animation begins (or when the screen goes black), press and hold Volume Up + Volume Down simultaneously.
  4. Keep holding until the device vibrates or a terminal prompt appears on the device screen (if the kernel supports it) or until your PC recognizes a new interface.
  5. Once in the shell, you can run commands to manage modules.

Disabling Modules via Terminal

If you successfully access the shell via adb shell or the on-device terminal, you can disable the problematic module without a full factory reset.

  1. Gain root access: su
  2. List active modules: magisk --list
  3. Disable the ReZygisk module. Since we cannot see the UI, we disable it by renaming its directory.
    magisk --remove-modules
    Note: The command magisk --remove-modules disables all modules. This is the safest nuclear option to ensure the device boots. If you need to keep other modules, navigate to /data/adb/modules and rename the ReZygisk folder (e.g., rezygisk to rezygisk.bak).
  4. Reboot the device: reboot

Root Cause Analysis: Why ReZygisk Failed

Understanding why the failure occurred is crucial to preventing it from happening again with Zygisk Next.

The “Basic Integrity” and CTS Issue

The user mentioned having only “Basic Integrity” but losing “Device Integrity.” This is a common issue with the OnePlus 8 on custom ROMs. Google Play Integrity API checks the device’s software state.

ReZygisk is designed to hide Zygisk hooks more effectively than standard Zygisk. However, if the module fails to initialize correctly due to a version mismatch with the Magisk version installed on crDroid 10.4, it can cause a boot loop. This is often seen when the Magisk app_process is modified incorrectly.

Conflicts with Shamiko and Zygisk Assistant

The user is running Shamiko and Zygisk Assistant. These are powerful tools, but they rely on a stable Zygisk foundation.

When installing ReZygisk, it essentially replaces the underlying Zygisk mechanism. If Shamiko is installed after ReZygisk, it might not detect the environment correctly. If installed before, the replacement process might break Shamiko’s mount points. This chain reaction is what likely caused the UI to die.

Zygisk Next vs. ReZygisk: Which is Safer?

The user is hesitant to try Zygisk Next due to the ReZygisk failure. It is important to note that while both modules aim to replace standard Zygisk, they are developed by different teams with different codebases.

ReZygisk is often considered a “fork” or an enhancement of standard Zygisk, focusing on stealth. Zygisk Next is a complete rewrite of the Zygisk module, aiming for better performance and compatibility with newer Magisk versions (v26+).

Should You Try Zygisk Next?

Based on the architecture of Zygisk Next, it is generally safer to try than ReZygisk in a post-ReZygisk failure environment because it does not rely on the same temporary file structures. However, the “black screen” error suggests a deeper compatibility issue with crDroid 10.4.

Recommendation: Before installing Zygisk Next, we must ensure the environment is pristine. The failure of ReZygisk might have left residual files in the /data/adb directory that conflict with Zygisk Next.

Comprehensive Guide to Hiding Root for Banking Apps

The primary motivation for these module changes is to bypass detection from Crédit Mutuel and France Identité. These apps use aggressive root detection methods that go beyond simple su checks.

1. The Importance of the DenyList (Magisk Hide)

Even with advanced modules, the Magisk DenyList is the first line of defense.

Critical Step: In Magisk settings, ensure “Enforce DenyList” is checked. However, standard DenyList is often not enough for these specific apps.

2. Shamiko: The Silent Partner

Shamiko is a module that works alongside Magisk’s DenyList. It hides the fact that the DenyList is active (which is itself a detectable trait). Shamiko is essential for Crédit Mutuel.

3. Zygisk Assistant (or similar modules)

Zygisk Assistant is crucial for France Identité. This app checks for the presence of Zygisk via specific library checks.

4. Native Detector and Systemless Hosts

The user mentioned Native Detector. This app checks for native root (Magisk in init_boot).

Step-by-Step Installation of Zygisk Next (Safe Method)

Since ReZygisk failed, we will proceed with extreme caution to install Zygisk Next.

Prerequisites:

The Procedure:

  1. Clean the Environment:

    • Open Magisk -> Modules.
    • Uninstall ReZygisk, Shamiko, and Zygisk Assistant.
    • Reboot.
    • Check if the device boots normally. If yes, proceed.

  2. Install Zygisk Next:

    • Download the latest Zygisk Next zip from the official GitHub repository.
    • Install it via Magisk -> Modules -> Install from Storage.
    • Do not reboot yet.

  3. Configure Zygisk Next (Crucial):

    • Open the Zygisk Next app (it acts as a configuration manager).
    • Enable “Zygisk” within the app.
    • Enable “Enforce DenyList” within the Zygisk Next app (this bypasses the need for Magisk’s native Enforce DenyList, which is often weaker).
    • Go to the “DenyList” tab inside Zygisk Next and add your banking apps and Native Detector.

  4. Reboot and Verify:

    • Reboot the device.
    • If the device boots, check Native Detector again. With Zygisk Next properly configured, “Native Access” should be hidden.

Specific Configuration for Crédit Mutuel and France Identité

These two apps require specific strategies that differ even between them.

Crédit Mutuel Work Profile Issues

The user noted that Crédit Mutuel works in the Work Profile but not the main profile. This is a classic sign of Zygisk detection.

France Identité and Device Integrity

France Identité is extremely sensitive to Device Integrity.

Troubleshooting the Black Screen (Post-Installation)

If you attempt Zygisk Next and encounter the black screen again, follow this recovery protocol immediately.

  1. Force Restart: Hold Power + Volume Down.
  2. Fastboot Mode: When the OnePlus logo appears, release Power but keep holding Volume Down until you see “Fastboot” on screen.
  3. Flash Magisk (Re-Install):
    • If you have TWRP, boot into Recovery.
    • Flash the Magisk APK (renamed to .zip) again.
    • This overwrites the current Magisk installation without deleting data.
    • Alternatively, use fastboot flash init_boot magisk_patched.img (if you have a patched image ready).
  4. Remove Modules via TWRP:
    • In TWRP, go to “Advanced” -> “File Manager.”
    • Navigate to /data/adb/modules.
    • Delete the zygisk_next folder.
    • Reboot.

Conclusion: A Safe Path Forward

The fear of bricking a device after a near-miss is a valid response. However, the solution lies in methodical isolation and testing. We recommend the following safe path for the OnePlus 8 user:

  1. Start Clean: Remove all Zygisk-related modules.
  2. Verify Boot: Ensure the device boots and passes basic integrity.
  3. Install Zygisk Next: As it is a newer, more stable codebase than ReZygisk.
  4. Install Play Integrity Fix: Essential for France Identité.
  5. Configure DenyList: Use Zygisk Next’s internal DenyList to hide Crédit Mutuel and Native Detector.
  6. Avoid Conflicts: Do not run Shamiko and Zygisk Next simultaneously unless specifically supported by the Zygisk Next documentation (usually, Zygisk Next replaces the need for Shamiko’s hiding capabilities).

By following this structured approach, you can minimize the risk of another black screen event and successfully hide root from even the most aggressive banking applications. The combination of Zygisk Next and a proper Play Integrity fix is currently the most effective method for users of custom ROMs on the OnePlus 8 platform.
