Try the serial recovery and got some reply as below but impossible to stop it with CTRL C, it just keeps rolling and rolling. Any idea guys?

Make sure your cable is hooked up correctly. You have to hook the cable's tx to the router's rx and cable's rx to the router's tx.

To make a long story short, I managed to convert my wrt-610n v2 to E3000 with the instructions found here, you guys really rock. <del>Then I followed the E3000 wiki and flashed the big firmware linked there. What a mistake!</del>(It's my own mistake, I downloaded the big image for wrt-610n v2, but my router has become an E3000 at that moment. I wish I was more careful, now it's too late). Now my wrt-610n v2 is bricked, and I tried everything suggested: timing the reset button, open it up and short the 8&9 pins, as well as the steps to tftp then flash wirelessly.
Nothing worked so far, so I think the only last resort for me is tht jtag. The problem is I don't know how-to.
Please, please, please...can someone from GTA kindly help a follow dd-wrter? A small fee will shold be ok 2.
Thans.
Rob

Which big build linked in the E3000 wiki did you flash? Being that i wrote a BIG chunk of that wiki, i do not recall ever linking a big build in the instructions..

Number 2, if you had converted your unit to an E3000 then how could you have bricked your WRT610N v2? After the conversion, you would no longer have a WRT610N v2, you would've had an E3000.. You didn't flash a BIG build meant for the WRT610N v2 onto your converted E3000, did you?

And the info will be important to know, de-brickers will want to know EXACTLY what happened.

You are 1000% right. Stupid me tried to flash a 610n image onto an already converted wrt-610n v2 (it's already an E3000 at that point). The wiki I followed was the wrt-610n v2 wiki.
Please don't be bothered by my silly comments about wiki. I was my mistake.
I am sorry.
Finally, thank you for the excellent work you have done for dd-wrt wiki. (I don't want to see other people make the same mistake, can we add some where on wrt-610n wiki in red: if you have converted the unit to an E3000, please follow the E3000 wiki here).

Possibly could be added as a redundant warning, though its covered many times, i'll try add it later at some point.

But as a future warning in general: if you convert your router from original to something else, it will no longer be in its original state, so you can no longer use the original instructions for what the unit once was..because it is no longer that.

have you performed a 30-30-30 reset prior to trying the serial connection? the CFE output doesn't look right no matter how you slice it, thats why i thought your cable is not hooked up correctly. even not being able to ctrl-c in time shouldn't have a CFE output looking like that (it should still look normal, which this does not) main times i have seen output look like that is either when the cable isn't hooked correctly, or a 30-30-30 wasn't performed or both..

So no one from GTA can do JTag on my bricked wrt-610n? Or is it because I have tried pin short a few times?

....aaaaand I bricked my e3000.

After updating firmware over wireless (absolutely fine!) multiple times, updating via VPN to the router that was the VPN host (safe as houses!) on al sorts of occasions, I go ahead and upload the mega build without the NV60K extention.

Now, to find a RS232/TTL level converter...

CA-42 clone cables are what i always use. Very cheap and easy to find on ebay or amazon, most times around $5-$7 a piece.
