The newly generated, clean QCN file is written back to the device's EFS partition, restoring network capabilities after a system reboot. Major Technical and Security Risks
On Qualcomm-powered smartphones, IMEI data is not stored in the Android operating system. Instead, it resides in a dedicated hardware partition called and EFS (Embedded File System) . Specifically, the IMEI values are stored in NV items 5010 and 5011 (for IMEI1 and IMEI2).
