Before you go JTAG crazy, you might have an easier option, which has
saved me in the past. On booting, the WRT54G will wait 1 second on
the most recently configured IP address for a TFTP PUT. On getting
one, it will accept a TFTP transfer and load it in to firmware. If
it doesn't receive one, it will attempt to boot via the traditional
method. I've successfully de-bricked a router twice using this
option.<br>
<br>
There is a more formal wiki introduction here:
<a href="http://oldwiki.openwrt.org/OpenWrtDocs%282f%29Installing%282f%29TFTP.html" target="_blank">http://oldwiki.openwrt.org/OpenWrtDocs%282f%29Installing%282f%29TFTP.html</a>,
but all you need to do is (on a linux and macos box)<br>
<br>
1) Hardcode your wired interface to something like <a href="http://192.168.1.2/24" target="_blank">192.168.1.2/24</a><br>
<br>
2) Type the following<br>
<br>
tftp 192.168.1.1 <br>
binary<br>
rexmt 1<br>
timeout 60<br>
trace<br>
<br>
3) Type this command but don't hit enter<br>
tftp> put $FILENAME.bin<br>
<br>
Hit enter and power up the router at about the same time; tftp will
constantly re-try.� It might take a few tries to win the race, so
don't get discouraged. I highly suggest using the vanilla Linksys
firmware for this :-).<br>
<br>
Best of luck!<br>

So I was trying to install DD-WRT on our router and managed to
brick it.� This wasn't entirely unexpected as it was pretty much a
last resort to try and get it working before buying a new one,
which I did.� But I thought if anybody knew how to unbrick it I
would love to learn.� From my cursory readings online it
apparently requires opening it and doing something related to the
acronym JTAG, but that's where things start to get fuzzy for me.�
Does anybody have any experience with this and is willing to teach
me?� It's a Linksys WRT54G.<br>
