Hi guys,

I was in the process of flashing a new build version of DD-WRT for my E3200 the other night by using the WebGUI method after a 30/30/30 reset.
I am now unable to log into the router after waiting for about 5 minutes for the flash process to complete to settle down.

I am unable to bring my router back to life unfortunately and have confirmed that I have bricked my E3200...

I have read some online guides (such as this one)

I'm not very confident in tinkering with the hardware side of things and I also don't have the required tools/components to perform it myself.

Can someone with experience and tools help me unbrick my E3200? Payment will be supplied for your services as well obviously.
Or can someone lend me the required tools so I can attempt to unbrick it myself? I would much prefer the former rather than the latter though.

Thanks,
Mazza

The hardest part is soldering pins onto the PCB if your soldering skills are average (like mine)

The USB <-> Serial adapter is only a few dollars. http://www.dx.com/p/pl2303hx-usb-to-ttl-converter-adapter-module-w-dubond-thread-blue-224704

http://wiki.openwrt.org/toh/linksys/e3200 has a picture of the PCB showing you where to solder the pins and what they are

I've done some more research and found out that I can just buy the converter locally (http://www.trademe.co.nz/Browse/Listing.aspx?id=756271143)

I'm no engineering major so I'm still a little confused as to what cables/pins I need to solder before the PC can communicate with the router...
I assume I need to wire the following:

Serial Cable - Router:
GND -> GND
TX - > RX
RX -> TX
Power (3.3v) -> Power (3.3v)

Can someone confirm if the above is correct?

According to http://www.dd-wrt.com/wiki/index.php/Serial_Recovery#Serial_Interfaces

Quote: "You need only grd, tx and rx connected properly for the serial interface to work." "Tx on the adapter goes to rx on the router and rx on the adapter goes to tx on the router."
