Hi, I'm a new user.[ Sorry for my english, but I'm Italian ]
I bought a WR841N 2 months ago on ebay. I tryed it, and it worked very well. Last week I loaded the firmware ( openwrt compatible with router), but yesterday I want to change back to default. I have reset the NVRAM the router doesn't work now ! I have a USB-TTL converter connect to pc and the JP1 of router. I open Putty and the program show this:

The router doesn't connect to the ethernet board. All LEDs turn on and off repeatedly. What can I do ? The Putty's terminal doesn't send anymore to the router because the cycle isn't interrupt.
ok, type "tpl" (very quickly) when serial console prints "Auto booting in 1 sec".
make your pc's lan ip address 192.168.1.100/24. and fire some tftp server (such as tftpd 4.00). put dd-wrt.bin in the tftp server's root directory. and you can upload the firmware by tftp using something like this:

it should stop. make sure your ttl connection is ok (tx is sending singal to rx on the router). you can try ctrl-c the console should show something like '^C'.

I have the same problem as Piccox earlier. I have a serial connection ( used: screen /dev/ttyUSB0 115200,cs8 ) and I can see "tpl" when I type, but nothing when I type 'Ctrl+C'(soemtimes a weired � character appeares). Is this meaning the problem of soldering or wrong console parameters?

hello,
Sorry for my english knowledge
I have a wr841nd v8.1 router and I tried to change the firmware but unfortunately I get an error message:
"uncompressing Kernel Image ... Too big uncompressed streamLZMA ERROR 1 - must RESET board to recover "
I can read from the router with "putty" (usb ttl serial converter) but I can't read any command the ttl converter works good, but I think that When I soldered the pinouts on the board I burned one of them I think that the "RX" pinout near to the Rx there is a little diode or resistant I don't know. But I couldn't write commands on putty. I know I made a very big probleme but how can I repair this pinout ? Or is there any chance ? another pinout for tx ?
Please help me in this case
Thank you very much.
