Hi Checho,
I bricked my wr1043 when I was trying to restore the factory firmware. I see the router rebooting in loops when I watch the leds. Do you think I can debrick using the serial port?

No, I haven't. Couldn't get it to boot properly, my guess is that the bootloader is damaged, or the memory, and the solutions are too complicated (changing memory and/or chip). It's easier and cheaper to buy a new one.
Thank you.
I also can't stop running strings like
...U-Boot 1.1.4 (Nov 17 2009 - 11:56:26)
AP83 (ar9100) U-boot 0.0.11
DRAM:
sri
32 MB...
F..k look like my RS232-TTL adapter connected RX wire (recieve data) and can show this running strings. But no connected TX (transmit data) and can't stop this process. Because TX of TTL don't send my "tp" or "tpl" commands from keyboard.
copy 'tpl' to your clipboard, so that you can just hit ctrl-v to paste it into putty. you have less than a second to get 'tpl' typed correctly during the boot sequence
I used terminal console soft - "Termite"
It has history slider, as bash in Linux - just press "UP" and last command appears in command line. So you should just press Enter. But it didn't help too.

I usually use putty, right click ( same as ctrl v ).
I think your router's rx isn't working. Check if you connected properly.
No, you mean remove some resistor or capacitor FROM MAINBOARD of tp-link? I think if I remove any part of that - it will last day of flashing leds of router and death
On RS232 -> TTL (named "DB9 converter" from eBay) no has any resistor.
I have the problem with sending commands into router. I've managed to get information through serial port, but it seems like router doesn't want to react on my commands.
I was trying to type 'tpl' fast, then copy-paste, hotkey. It just do nothing and still reseting. The weird is that TX LED on USB<->TTL device is blinking while I'm typing tpl.
Do you have any ideas what to do?
