1. What is Trigger Anti-Crack Exceptions Error?

The “Trigger Anti-Crack Exceptions” error is a security feature implemented by Transsion Holdings on their newer Android devices (Tecno, Infinix, Itel). This error typically appears after:

• Flashing custom ROM or unofficial firmware
• Failed OTA system updates
• System modification or rooting attempts
• Corrupted system files
• Interrupted update process

When this error triggers, your phone becomes stuck in a boot loop. It boots into recovery mode, shows the error, and any attempt to reboot normally sends it right back to the same recovery screen. This makes your phone completely unusable until the error is resolved.

2. Error Symptoms

If your device has this issue, you will see:

• Android Recovery menu displayed on screen
• Red text message: “Custom Recovery UI”
• Red text message: “trigger anti-crack exceptions”
• Two options only: Shut Down or Reboot to Normal
• Reboot loop: Selecting Reboot to Normal turns phone off and boots back to same error
• Cannot access normal system: Phone is completely blocked

3. Devices Compatible with This Fix

This free method works on all Transsion devices regardless of processor type:

Processor Support:

• MediaTek (MTK) - All models
• Spreadtrum / Unisoc (SPD) - All models
• Qualcomm - All models

4. How This Fix Works (Meta Mode Method)

Unlike other solutions that require different tools for different brands, this method uses the official Aftersales Tool for Transsion devices. The tool automatically detects your device and uses Meta Mode communication protocol. You only need to select your CPU type (MTK, SPD, or Qualcomm), and the tool handles everything else.

The fix works by:

1. Booting your powered-off phone through the tool
2. Writing authentication parameters to the device
3. Resetting the anti-crack trigger flag
4. Restoring normal boot functionality

5. Tools Required (All Free)

Before starting, download these free tools:

Important: Visit the Aftersales Tool article above for complete installation instructions and how to use the tool without username/password.

6. Step-by-Step Fix Guide

Follow these steps carefully. Do not skip any step.

Step 1: Install Required Drivers

Before connecting your phone, install the correct USB drivers for your device’s processor:

• For Infinix/Tecno/Itel with MTK processor → Install MediaTek drivers
• For SPD/Unisoc based devices → Install SPD drivers
• For Qualcomm based devices → Install Qualcomm drivers

Step 2: Power Off Your Phone Completely

Press and hold the power button. Select “Shut Down” from the recovery menu. Make sure the phone is completely powered off. Do not connect it to the computer yet.

Step 3: Launch Aftersales Tool

Open the Aftersales Tool on your Windows PC. Run it as Administrator (right-click → Run as Administrator).

Step 4: Select Your CPU Type

In the tool interface, select your device’s processor type:

• MTK for MediaTek powered devices
• SPD for Spreadtrum/Unisoc powered devices
• Qualcomm for Qualcomm powered devices

The tool will use Meta Mode method automatically. You do not need to select any brand or model. The tool works the same way regardless of which Transsion device you have.

Step 5: Connect Your Powered-Off Phone

Connect your powered-off phone to the computer using a good quality USB data cable. The tool will automatically detect the phone and boot it completely. Wait for the tool to finish booting the device.

Step 6: Navigate to Set Parameter / Start Authe Tab

Once the phone is successfully booted by the tool, click on the “Set Parameter / Start Authe” tab. You will see three buttons in this tab.

Step 7: Click First Button - Start Parameter Writing

Click on the first button labeled “Start Parameter Writing” . Wait a few seconds. You will see some success messages followed by red error messages.

Ignore the red errors. The red errors appear because we did not select any file and we are not writing anything. This is normal behavior. The process is still working correctly.

Step 8: Click Second Button - Authentication 2.0 Writing

After the first step completes, click on the second button labeled “Authentication 2.0 Writing” . You will see a success message confirming the authentication has been written to your device.

Step 9: Disconnect Device

Click on the “Disconnect device” button in the tool. You can now safely unplug your phone from the computer.

Step 10: Power On Device Manually

Press and hold the power button on your phone to turn it on. This time, your phone will boot normally into Android. The recovery error and “Trigger Anti-Crack Exceptions” message will no longer appear.

Step 11: Complete Device Setup

Your phone will boot like a fresh device. Complete the initial setup and enjoy your fully functional phone. This fix works on Android 14 and Android 15 devices.
