radau viena posta intike apie atbrikinima, tik truksta adapterio, gal kas 
toki turi ar galima lengvai pasigaminti?

I bricked my TL-WR1043ND too a few times and recovered it successfully every 
time.
You can find the way to recover your unit on the OpenWRT site.

Here are the steps:

1. Download modified original firmware that has first 0x20200 cut off, or 
use firmware attached below.
2. Gain access to the serial port and hook it up to your computer using 
RS-232 / USB --> TTL adapter.
3. Install Putty, setup Serial connection, set COM port appropiately to your 
adapter in step 2 and do not click Open yet
4. set networkcard of computer to ip address: 192.168.0.5 , subnetmask 
255.255.255.0 and no gateway
5. Install TFTP32 server (google it) on your computer, connect computer with 
ethernet cable to LAN switch port on router.
6. Make sure the "Current Directory" in TFTP32 is set to folder with 
modified original firmware renamed to "code.bin"
7. In Putty, click open and plug in Power cord to router... you should see 
bootloader coming up now...
8. You will see something like this:

No valid address in Flash. Using fixed address
: cfg1 0xf cfg2 0x7114
eth0 up
eth0
Autobooting in 1 seconds## Booting image bf0200000...

Then type following fast: tpl

Now you will get into the command prompt and you're able to execute 
commands.

9. Erase the firmware before writing it again using following command: erase 
0xbf020000 +7c0000
10. Download new modified original firmware from computer to the router: 
tftpboot 0x81000000 code.bin
11. Write the downloaded firmware to flash using: cp.b 0x81000000 0xbf020000 
0x7c0000
12. Boot the original firmware again: bootm 0xbf020000

Your router should be unbricked again!
