This paper explores the technical architecture and utility of an integrated diagnostic and reset tool designed for major mobile platforms, including Samsung, LG, HTC, Huawei, and Qualcomm-based devices.

Addresses the specific HiSilicon Kirin chipset requirements and specialized "Test Point" methods for EDL access.

Facilitates communication between the device and radio diagnostic software (like QPST or QXDM) for IMEI repair, network calibration, and band unlocking.

Provides legacy support for older security protocols and specific Diag-enable codes (e.g., ##DIAG#). Conclusion

Automates the removal of Factory Reset Protection (FRP) and user-defined locks across various security patch levels.
