Connect your phone to your PC and enable Diagnostic Mode (usually via ADB: setprop sys.usb.config diag,adb ).

Fully compatible with dual-SIM configurations, allowing separate reconstruction of IMEI 1 and IMEI 2.

Your phone must communicate via a specialized diagnostic port. Connect your phone to the PC via USB, open a command prompt (ADB), and type the following commands: adb shell su setprop sys.usb.config diag,adb Use code with caution.

When dealing with cellular connectivity issues, network signal loss, or "IMEI null" errors on Qualcomm-based devices, specialized software is required to restore functionality. The is a widely utilized utility designed to back up, restore, and repair QCN (Qualcomm Calibration Network) files. Reinstall the Qualcomm USB drivers and check the

Rewrites missing or corrupted IMEI numbers back to the device's NVRAM/EFS partition (restricted to legal ownership restoration).

To understand the utility of the IMEI QCN Tool, one must first understand the technology it manipulates. QCN stands for Qualcomm Calibration Network . It is a file format used by devices with Qualcomm chipsets to store essential radio configuration data. This data includes the all-important IMEI (International Mobile Equipment Identity) number, which is the unique identifier used by cellular networks to authorize a device. If a phone’s QCN partition becomes corrupted—often due to a failed software update or improper rooting—the device will lose its ability to connect to mobile networks. In this context, the "IMEI QCN Tool" serves a legitimate purpose: it allows technicians to back up existing data or restore a functioning configuration to a device that has been rendered useless by software corruption.

: This is a binary file that stores all the critical configuration data for the baseband processor on a Qualcomm‑based device. It contains the device’s IMEI, MEID, ESN, radio calibration values, Wi‑Fi and Bluetooth MAC addresses, and many other network‑related settings. Think of the QCN file as the “identity blueprint” of your phone’s modem – without a valid QCN, the device cannot properly register on a cellular network.

The QCN file is stored inside the EFS (Embedded File System) partition of the phone, and it is created during the factory calibration process. When a user inadvertently wipes this partition (e.g., while flashing a custom ROM or using the wrong fastboot command), the IMEI can be lost, leading to a phone that can no longer make calls or connect to mobile data. A is therefore your insurance policy against such disasters. Small file size and low system resource consumption

The IMEI QCN Tool v1.0 is favored for its simplicity and direct functionality. Key features include:

Extract the downloaded zip file and run the tool executable as an Administrator. Step 3: Connect and Detect

Users must ensure they only restore the original IMEI belonging to their specific hardware unit. If you need help setting up the software, let me know: What is the exact of your device?

“IMEI QCN tools” is a general term for software utilities that allow you to read, backup, restore, or edit the QCN file on a Qualcomm‑based Android device. Most of these tools operate through the phone’s , which gives the PC low‑level access to the modem’s NV (Non‑Volatile) items.
