Hello,
Can someone please help on how to fix that router from bricking?
First I don't remember which region was the stock tp-link firmware as I saw after flashing ddwrt firmware it says something about :wrong version of firmware was flashed:
After I tried with tftp64 to recover the stock firmware and the very annoing thing is it start to write the firmware but the transef speed is around 1kb/sec which is very weird and after 60 sec. it says timeout error occurs.
The label of the router is in attchment.

try with switch between the router and your PC ..if TFTP is working ok it should be ok...
you have to rename file, to the tftp name required/requested...you can see the log in TFTP for the file name requested...it would be something like TP-link-recovery-archerv2.bin...
Tp-Links TFTP is solid and you can unbrick it with ease ..
p.s. as looking at your pic your archer is non US nor IL version so use the other .bin files..(normal)
if you get the correct name, for the tftp it should work...100% _________________ Atheros

Set anticipation window to 1024 or 2048. _________________ "The woods are lovely, dark and deep,

i tried almost everything but without luck.
when i try to flash on the router during flashing there is main power light,that sun light and wifi light but not anz light from lan.
What I tried to flash is the those two images from the link above.

On the latter, I do not know if this is OpenWRT's bootloader or the stock OEM firmware bootloader. If using anticipation window of 1024 bytes on tftpd32/64, unmanaged switch in between PC and router, and static IP of 192.168.0.66 on the PC does not work with LAN or WAN ports, then the only options are serial or JTAG. _________________ "The woods are lovely, dark and deep,

So I tried to flash with tftpd64 and serial console. I cannot see right the words after start flashing in the putty console.
It is all gibberish words, and after flashing is done it just reboot it continuosly after 5 sec.
finally, there is a time window to interrupt the serial with tpl
than when in serial mode, you have to erase and re-write the recovery/firmware.bin again using tftp to upload the file.bin (read the openwrt link carefully... if its not responding on those moves...than its something very wrong...and it may be beyond recover... _________________ Atheros

It means you have to connect TransmitX to RceiveX and RceiveX to TransmitX...
As many people believe it should be TX to TX and RX to RX...and its wrong... _________________ Atheros

To clarify: The TX on the router PCB is connected to the RX on the USB-UART-TTL adapter and the RX on the router PCB is connected to the TX on the USB-UART-TTL adapter. And no, not kidding. Many people over the course of this forum's existence and elsewhere have gotten it wrong many times and couldn't figure out why it wouldn't work. Also, any bad connections will affect output in the PuTTY terminal. _________________ "The woods are lovely, dark and deep,

Change the cables from tx to rx exactly as you described above.In that case nothing happend in putty during flash while on adapter ttl/usb blinked two red lights which means is wrong cables connected.
Set it up putty to 115200,added vt100 in translation,parity none,flow control none,stop bit 1.
In tftpd64 i set it up also exactly as mention above the link.
And I tried almost all stock firmwares from tp link,ddwrt and openwrt without any progress.
All the time when I try to flash with tftpd,it goes to finish uploading with the image but after reboot it start to blinking the lights for 5 sec. and it restart the router and so over.
I think that bootloader is somehow broken because I cannot sent 'tpl' command in putty and I see only gibberish words.
