You need to have the serial to USB cable operating at 3.3 volt. Please do not try any other cable except the one specified in http://www.myopenrouter.com/article/10341/Recover-Your-WGR614L-Using-a-Serial... - this may brick your router..

So, I have bricked my router with the newest DD-WRT firmware posted on this site. Maybe I was in bad luck (because I flashed it successfully with tomato and MRO several times before.) The POWER LED of the router does not blink at all so I don't think that I can debrick it with TFTP. The router has solid POWER and CHECK lights solid and whichever port I connect my LAN cable to solid.
I wonder if I could use my serial port on my laptop which is a Dell D610 to connect the JTAG or the USB to serial 3.3Volts cable is strictly needed, because I will have to order it and wait for weeks to begin using my router which is a little bit silly.
Thanks.

That's not exactly true - you can use a serial level shifter too based on MAX3221.

So, I went ahead and tried to connect the JTAG pins with my laptop. Something was going on but they were all garbages (not readable characters) on my terminal. I tried with several different computers. So is that a sign to indicate my voltage rating is not correct?
