Write At Command Station V1.0.4 is a specialized utility designed for mobile technicians and enthusiasts to repair or modify device identification data—specifically IMEI numbers—on MediaTek (MTK) powered smartphones and tablets. The "Fix" version often refers to a patched or updated build intended to resolve compatibility issues with newer Windows versions or specific chipset drivers. Core Functionality

The tool operates by sending AT commands to the device's modem through a COM port. Key features include:

IMEI Repair: Restoring original IMEI numbers lost after a firmware flash or "baseband unknown" error.

Backup/Restore: Saving existing calibration data before making changes.

Network Tuning: Accessing low-level modem settings to troubleshoot connectivity or signal issues. How to Use the Tool

Preparation: Ensure the correct VCOM or MTK USB Drivers are installed on your Windows PC to allow the software to recognize the device in Meta or Preloader mode.

Connection: Connect your device via USB while it is powered off or in a specific diagnostic state, depending on the model.

Command Execution: Use the interface to select the target COM port and input the necessary AT commands (e.g., AT +EGMR=1,7,"IMEI_NUMBER") to update the hardware registers.

Verification: After the process, reboot the device and dial *#06# to verify the changes have taken effect. Security and Safety

Downloads for this tool are frequently found on community-driven repositories like HalabTech Support or various Google Drive links shared in technical forums. Because it is a third-party modification tool, it is critical to:

Scan for Malware: Always run the .exe file through a security suite before execution.

Legal Compliance: Changing an IMEI number is illegal in many jurisdictions if the intent is to mask a stolen device's identity. Use this tool only for legitimate repairs of the original hardware ID. Write At Command Station V1.0.4 Download - Google Docs
