Hi,
I brick my WNR3500Lv2. I try to make RS232 cable with 3 pins (GND, Rx and Tx). I set Putty to comunnicate with my COM port with 115200bps, 8,1,none,none. When power on my Router, console on putty display unreadable characters:

I press fwe time CTRL+C, but nothing. When I set my IP to 192.168.1.106/255.255.255.0, GW: 192.168.1.1, DNS: 192.168.1.1, ping replies 2 times when I turn on router.
I found in Google, I can short two pins when turn on router for WNR3500L, but in WNR3500Lv2 don't have this pins.
How I can unbrick my router?
Regards!
try to change you connection speed to 9600
Can you please tell how did you bricked your router ??
Have you tried a hard reset ??
I fixed my problem. The problem was that I did not use the USB-TTL cable, I used a standard serial cable. When using a USB-TTL cable everything was OK.
Good to know that things are working.
Thanks for that post!
I have the same problem with using RS232 cabel.
Router answers but it looks like at 1st post.
It seems that using USB-TTL cable is necessary :(
Well worth the investment. Once you have one and are familiar with how they work you are less concerend with making changes cause you can always fix something if it breaks.
when you receive the 2 ping replies the router will look for the file vmlinuz on tftp server on 192.168.1.2. You can use this method to unbrick if you forgot your ttl cable ;)
