Many mobile flashing tools trigger false positives in Windows Defender due to how they interact with USB hardware kernels. Ensure you download the zip archive from reputable sources, and temporarily disable real-time protection if the tool is blocked from launching.
You must enable Diagnostic Mode on your phone (usually via ADB command setprop sys.usb.config diag,adb or a dialer code) so the computer can communicate with the modem.
Use the application's file interface to load the target .qcn file. Step 3: Inject the Original Identity
The tool is typically part of a larger repair workflow. Technicians often use it alongside other software like (Qualcomm Flash Image Loader) or QPST (Qualcomm Product Support Tools) to backup an original QCN, modify it with the correct IMEI using the Tungtata tool, and then restore it to the device.

Once finished, restart your phone. Your network signal should return, and your IMEI should be restored to its original state. Safety Warnings
Often used in conjunction with other tools to rewrite or fix corrupted IMEI numbers by editing the QCN file.
