I need help unbricking my Zyxel 2812 router after playing around a bit too much :-P

It looks like LAN3 is working on it, but im not getting any IP.

Tried varoius settings for network such as:
192.168.1.33/24 and gateway as 192.168.1.1

TFTP is unable to upload FW.

When i connect to serial port on it, it just loops:

ROM VER: 1.0.5
CFG 01

Tried with 30 second reset with power on and 30 second reset without power on.

Anyone got any other suggestion other than to JTAG it?

    Seems the way is to use UART load by high/low pin combination of CPU
