The current (Does it say "Unknown" in settings?).
Modifying NVRAM data and repairing IMEIs carries risks. Legally, you should only write or restore the original IMEI numbers printed on your device's box or battery housing. Changing an IMEI to match a different device is illegal in many jurisdictions. Proceed at your own risk. Prerequisites A Windows PC. A high-quality USB data cable. Qualcomm USB Drivers installed on the computer. An Android device powered by a Qualcomm Snapdragon chipset.

Opens raw .qcn backups extracted from Qualcomm devices to modify internal values. Changing an IMEI to match a different device
Working with NV items and QCN blocks carries a risk of permanently breaking a phone’s radio capabilities if done incorrectly. Follow this general workflow to ensure a safe modification process. Step 1: Extract and Set Up
QCN (Qualcomm Calibration Network) files contain critical calibration data, including IMEI numbers, network configuration, and MAC addresses.
Kaelen was a relic diver—someone who hunted pre-fall engineering tools. QCN stood for Qualcomm Calibration Network , a protocol used to rebuild broken radio hardware. But “Tungtata”? That wasn’t in any dictionary. Some old-timers whispered it was the name of a dead language. Or a person. Or a scream.
Before diving into the tool itself, it’s important to understand the file. This file resides in the device's Non-Volatile (NV) memory. It contains essential calibration data for your phone’s radio frequency (RF) hardware, including: IMEI Numbers: International Mobile Equipment Identity.
