Support appeared in r28078, so you can download an Attitude Adjustment (12.09 final)

Unfortunately, the firmware cannot be installed by factory web configuration utility. Someone may try to build the sources from ftp://opensource.zyxel.com/NBG-419N to check what is needed for it. Open the case, connect a TTL-to-RS232 converter cable (not the standard serial cable!) - see port.serial. I used Nokia CA-50 cable. Port speed is 57600, 8 databits, no parity, 1 stopbits, both hardware and software flow control must be disabled. The router does not power on when serial cable is connected, so you have to connect the cable after powering on. If you miss the bootloader (U-Boot) prompt, wait until ZyXEL Linux boots and issue
reboot. When you see U-Boot prompt, press 2:
Please choose the operation: 1: Load system code to SDRAM via TFTP. 2: Load system code then write to Flash via TFTP. 3: Boot system code via Flash (default). 4: Entr boot command line interface. 6: To emergency. 9: Load Boot Loader code then write to Flash via TFTP.

openwrt.bin. Connect one of the router's LAN ports and TFTP server to the same LAN.
Then press Y and enter IP for your device, TFTP server and firmware image file name:
