Problem: Xiaomi AX3600 Bricked After Flashing NSS Build (Orange LED, No Network Activity)

HI

I attempted to flash my Xiaomi AX3600 router with a custom firmware that includes Qualcomm NSS (Network Subsystem) support from this GitHub repository:

After flashing, the router no longer boots properly.

Symptoms:

  • The system LED stays solid orange after power-up.
  • No network activity — the router does not request an IP via DHCP (confirmed via Wireshark).
  • TFTP recovery does not work. No packets are sent from the router.
  • Static IP and properly named recovery image (e.g. C0A81F02.img) were used for TFTP recovery without success.
  • Tried holding the reset button during boot — no change.

Attempts:

  • Configured TFTP server on 192.168.31.100 with correct image name and static IP — no success.
  • Wireshark shows no packets from the router at all (no DHCP, no ARP).
  • Repeated recovery attempts on different LAN ports — still nothing.

With all due respect - the Qualcomm NSS builds are experimental, and as such, a bit of a hair shirt...

Expect things to be broken, and broken often - good for testing, not for production at the moment...
