K2001N NWD Firmware: Enhancing Network Performance and Security

• Enable SSH or serial console for low‑level debugging and kernel logs (dmesg).
• Use a partitioned A/B flash layout when possible—supports seamless rollback.
• Enable and collect system logs (syslog) and network captures (tcpdump) when diagnosing issues.
• For custom development, build reproducible firmware images using OpenWrt or vendor SDKs when supported; test in a VM or spare device first.

• If firmware/bootloader supports it, use built-in backup or dump via serial/TFTP.
• Copy configuration files from the UI or CLI.
• Create image of internal storage (if accessible) using dd over serial/shell or vendor tool.

• Use vendor-specific serial flasher (e.g., RKTool, Rockchip, Amlogic loaders) to push image over USB in loader mode.
