1. USB enumeration: Device presents multiple interfaces – ADB, MTP, and Diag (Diagnostic) port (usually USB CDC or serial).
2. Handshake: Tool sends proprietary authentication tokens to the modem’s bootloader (some versions use leaked Huawei signing keys).
3. Low-level memory access: Using NV_RW commands, the tool reads/writes to NVRAM partitions (e.g., modem_secure, nvme).
4. Flashing: For firmware, it switches to fastboot and sends partition images (boot, recovery, system) via fastboot flash or over Diag using DOWNLOAD protocol.
5. Unlock: Reads bootloader lock status, calculates unlock code from device’s serial number + vendor’s secret key (old method) or uses an exploit in the bootloader (newer).
