Minimalist design for quick navigation. How to Use the Tool

Open the IMEI QCN Tool V10 as an Administrator.

The IMEI QCN Tool V10 is a specialized utility designed for servicing Qualcomm-based smartphones. It is primarily used by technicians to repair or restore the handset’s Critical Network Data (QCN) files. When a device experiences "No Service," "Invalid IMEI," or "Radio Off" issues following a firmware flash, this tool is often the primary solution.

Latest drivers must be installed for port recognition.

To ensure the tool functions correctly, your system must meet the following requirements: Windows 7, 8, 10, or 11 (64-bit recommended).

Use a high-quality USB cable to connect your phone to the computer.
