Qualcomm Imei Rebuilder Tool (LIMITED)
Many repair tutorials warn to "backup QCN before flashing." If a technician forgets this step and corrupts the IMEI, the rebuilder tool can manually inject the original IMEI (printed on the device box or under the battery).
The tool reads the device's QCN (Qualcomm Calibration Network) files and allows for the modification of the hexadecimal strings representing the IMEI. qualcomm imei rebuilder tool
