Hi folks, I have trouble unbricking a WRT54G v3.1. Symptoms: No pings anwered at 192.168.1.1 even when pc network card is set at fixed ip and 10MB/half duplex. Blinking led. What I've tried and failed so far: - resetting 5secs or 30secs - Shorting pins 15&16, 5&6 and 16&17 of the flash while plugging the powercord in - I've modified a HP RS232<->USB cable to connect to the serial port of the router with success. It dumps the following repeatedly (after the exception it seems to reboot): Code: CFE version 1.0.37 for BCM947XX (32bit,SP,LE) Build Date: Fri May 27 13:33:52 CST 2005 (email@example.com) Copyright (C) 2000,2001,2002,2003 Broadcom Corporation.

I assume it could be a crc error or memory read error. How can I resolve this issue? Would building a jtag cable be a solution or is the board too screwed up? I've googled for a while now and can't seem to find an answer. TIA!
