My Linksys WRT54G version 5 suddenly stopped working over the weekend. On powering the router, all lights powered on and stayed that way. I had previously been running DD-WRT Micro.I tried holding the reset button for 30 seconds, powering the router, holding for another 30 seconds and then usnig TFTP tool to flash the router but that did not work. My situation was desperate and I was ready for desperate measures. So I used this guide : http://voidmain.is-a-geek.net/redhat/wrt54g_revival.html So I had to open up the router and short out pins 15-16 on the chip. The problem though was that in the pictures I saw, there were differences in the location of some of the components. So I’m posting a picture of what my board looks like just in case anyone has something similar to mine:

I won’t go into the details of the process since they are already documented elsewhere. All I’ll add is, funnily enough, after shorting out the pins, my router started working properly without me needed to reflash the firmware. Might work differently for you though.
