I went through updating the original software but power went off during update process and now the router is unusable. The power LED is blinking, but not even the reset button works Any way I can revive it? It's urgent. Thanks.

If you're handy with electronics, you could solder the header on the JTAG port and use that to reflash it (i.e. CFE.BIN, then you should be able to tftp the firmware over -- I'd use Tomato or DD-WRT instead).

Often TFTP works (assuming you have boot delay on), but not with the factory firmware...

I am handy with electronics (it was my hobby before pc's came around). Which one is the JTAG port? The router does NOT start at all and no connection can be made to it.

First pic found using Google (plenty more of them around)

Not a problem.

Which contacts should i solder in the JTAG port?

I'd just solder a full pin header in there. Then use a IDC connector on it (part of your JTAG cable). If you're in a hurry and don't have some parts on hand, look at typical JTAG cable schematics, you'll see what you need.

Now's a good time to solder the other pin header as well (for serial ports -- 3.3v though!)

Thanks! I owe you a coffee
