Thanks.. Everyone knows I fix routers for fun, not for money. This is exactly why I ask:

1). What bricked the router?

2). Did you take the router apart?

3). If yes, did you pin short?

If the answer to # 3 is yes, I won't even look at the router.

What typically takes on a couple of beers to fix, this one took two cases of beer. I should'a just sent it back but the owner explained that they had never been inside the router and they had purchased it as I received it from e-bay.

I'm not saying I do not enjoy a couple of head scratchers from time to time, I just get emotional when I see needless damage caused by stupidity.

Then I started to feel bad and decided to give it a lash plus I like the challenge.

Here is the pisser... Not only do I have 6+ hours into this thing and two cases of beer Razz I got the return postage paypal'd to me and PP charged me a fee. They have never done that before.

So this one cost me two cases of beer, 6 hours, and 53 cents to fix. Evil or Very Mad

On a personal level, I pin shorted (pin 9) my Asus WL-500W and thanks to that I have a working router again.

redhawk is right in saying that pin shorting is a "last method" but it does work if you do it right and know what you are doing.

Ok I admin. I'm sorry. I'm dumb. I'm terrible. I was having boot problems on my fairly new WL-500W that I couldn't seem to repair using any of the many methods found here and in the wiki. So I resorted to the pin shorting after seeing some success by others. I followed the recommendations of using a needle, ensuring system is off and, just plain being careful.

It seemed to fix it (very very lucky) and I don't see any visible damages or faulty connections (via multimeter) around the board's area that was used. But I now REALLY worry that although the software works, the hardware may be botched somewhere else.

Are there any consistent hardware issues that are known as a result of the shorting that I can watch out for?

Thank you. And again, I am SORRY for not taking the patience to read more into safer methods such as serial and JTAG!

I pin shorted my WL500W about 2 months ago...No noticeable problems.... Been through several build upgrades, and I whore my bandwidth with it...


Still, it should only be used as a LAST ditch method..

What is pin-shorting supposed to do - is on the address or data lines? Is the idea to fail the nvram read so it just resets to defaults and sits on the CFE waiting for tftp?

The Asus RT-N16 CFE checks the reset or WPS button before reading the nvram - couldn't we get CFEs for other routers that are equally robust? Of course over-writing the CFE without JTAG is risky...

Actually, I did get by with doing the pin shorting on an old bricked WRT300N, but after reading this topic, I wouldn't do it again. Had it been a router that I actually cared about, I probably wouldn't have done it. I agree, if you don't care whether you fry one or not, what the heck, go ahead and do it; I just happened to get lucky lol.

It's worth being very clear on this: proper pin shorting is not the problem. Careless pin shorting is the problem. I realize anecdotal evidence only goes so far, but I have a WRT54GSv2 with the "sdram_init" value problem, causing it to brick when 30-30-30'd or when it tries to reset settings. I've pin shorted 15-16 over a dozen times to get it to take a firmware, with zero problems. I've found that a small jeweler's screwdriver, placed between the contact pads and angled just a bit, works just dandy.

Since everybody always rails against pin shorting, though, I finally decided to update the cfe, since that's the recommended fix. Now the router is truly bricked, and even a pin short won't help, so I'm relegated to installing a JTAG. Yes, careless pin shorting can cause permanent damage, whereas careless cfe editing can be fixed--with a soldering iron (as if THAT can't do any damage!).
