How to recover the board using a serial console is outlined in http://www.myopenrouter.com/article/10341/Recover-Your-WGR614L-Using-a-Serial...
The other option is to try the reset button.
The reset button is at the back of the router hidden besides the Antenna connector. You should keep the button while powering up the WGR614L and it should get you back the dd-wrt firmware unless some critical flash sections were overwritten.
Ok I bought 2 WGR614Ls with the intention of using them to network my 360/PS3/Dish Network reciever with my DSL modem.
I flash both with the version of DD-WRT that I got from here. So far so good, firmware up and running and everything seems fine aside from the removal of the "keep alive" functionality in the PPPoE "connect on demand" in v24 of dd-wrt. I work around that and get one router up and running with the DSL modem.
I operate my network on the IP range 10.1.1.XXX. My DSL modem was 10.1.1.1 with DHCP enabled. The host router was 10.1.1.2 with DHCP disabled.
Then I begin to set up the 2nd router in client bridge mode. I start by changing its IP to 10.1.1.3 subnet of 255.255.255.0 and gateway and DNS of 10.1.1.2 and hit save. I then disable DHCP and save. I then change my computers IP to a static IP of 10.1.1.100 with a gateway of 10.1.1.3 save and reset the router to make sure the changes took effect.
The process bricked the router. I get nothing on 10.1.1.3 and nothing on 192.168.1.1 which are the only two IP addresses it should have. I've tried multiple resets using multiple techniques and can't get anything. There's nothing pingable that I can find and even after a reset there's no DHCP, nothing at 10.1.1.3 and nothing at 192.168.1.1 which is the default. As near as I can tell there's not even any TFTP going on...
So I say to myself, ok thats a fluke. Something went bad in the reboot. So I pull out my trusty old WRT54G loaded with DD-WRT v23SP2 which has served me well for quite some time. I set it up on the DSL modem and proceed to try and bridge my second 614L to the WRT54G.
This time I don't have to change any IP addresses. My 54G is already set to 10.1.1.1 and the 614L is at 10.1.1.2 so it should work. I disable DHCP, save, make a change in the wireless setup to client bridge and change the channel to 10 and save. I then setup my computer with a static IP again. I then reboot the router and boom its bricked as well. Same story as the first.
#1 Does anybody have any clue WTF is going on that simple changes and reboots are bricking the router AFTER the flash is done?
#2 Can anybody give me some advice on how to unbrick these two?
Any help is greatly appreciated because if I can't fix this, I'm out $120....

Like I said, I tried the reset button. I've done it with power on, power off, power off to power on, power on to power off, power on to power off to power on and any other combination you can think of. I've even tried resetting in those combinations and letting the router sit powered down overnight as that once brought my 54G back to life once.
I guess my only option is to get the serial cable and unbrick it that way.
I'd still like to know exactly WTF happened where simple setting changes bricked the router and if anyone else has had this issue...

This seems to be an odd issue. I will check it out and see if I get the same problem.
This type of bricking (and the reset is not working) means something more than just nvram corruption happened.

Are you using Firefox when you preform the flash? For whatever reason if you flash using this browser it can cause problems. In this instance alone I would have to recommend that you use IE. I don't know if this holds true for other browsers out there but I do know that Firefox can glitch out DD-WRT firmware during a flash. Try checking your ethernet cable. Just some ideas...

I did use firefox for the flash but the firmware was up and running and had been for a couple days when I got around to trying to bridge the routers. From now on I'll make sure to just use IE, whether I'm flashing or adjusting.
Ethernet cables are good. I tried the 2 that came with the routers plus a few more I had laying around.
On the upside my serial cable should be here today. Now if I can only find my soldering iron...

1 router recovered to stock firmware, 1 to go. Thanks for the help guys...
ETA
Now 2 recovered. Now back to my original intention of bridging the routers...

I suspect the same happened to me.
My only way around was to login through the wireless interface and get rid of the gateway specification (bringing it back to "0.0.0.0").
I did get the web interface from my wireless machine.
