Excuse me for my poor English.
I live in Argentina.

Well... I've a TP-Link TL-WR841N. I put the firmware DD-WRT but flash it will send another version (ie the one I've is the TP-Link TL-WR841N V8 and I will send V7.x.

The Power light is on. The other lights were flashing... it impossible to access the router on the LAN/WAN ports.

Here how I relive?
There is a procedure to revive without connecting with some additional wiring?

I am looking for the steps but cann't find it anywhere.

Give me a hand?

THX!

I already have the USB adapter that emulates RS232 Serial Cable.
The issue is that the router will flash all the lights except the Power...

I don't have Telnet access to it.

Solder the wires according to the diagram:



Ok... Now?

How do I access to flash it via serial?

The Router is bricked by DD-WRT.

OMG!

I don't understand...

I've no way of communicating the Router...

http://youtu.be/uE18QQ0HEF0


According to the video, I don't acced by Putty...
Not for Hyperterminal.

Then?

I don't understand those steps... I connect the router and quickly squeezed in Putty CTRL+C several times until it is what the tutorial?

In Hyperterminal I feel the same, it is the white screen...


Could you please explain step by step as if it were a baby?

RS-232 is +12V/-12V signal level, your routers serial port is 3V/0V TTL level.
You need to use a USB<->TTL serial adapter, not a USB<->RS-232

Don't use the wan port, use a lan port.

Well... Definitely the problem is the TFTP server.

Intented mount TFTP Server with various programs and nothing.
As no mounts can't upload OpenWRT to the Router.

If anyone knows how to mount TFTP Server is appreciated!

PS:

NIC


Config TFTP




Now when I open the TFTP Server, I get in default IP 127.0.0.1 software... I mean, don't grasp that I put in the options.

The TFTP Server directly doesn't work.





Operating System: Windows 7 Home Premium X64

Use this tutorial: http://wiki.openwrt.org/toh/tp-link/tl-wr841nd#tftp.install

After finished all the steps, the LOG throws the following:

Autobooting in 1 seconds
## Booting image at 9f020000 ...
Uncompressing Kernel Image ... Too big uncompressed streamLZMA ERROR 1 - must RESET board to recover


What do I do?
