TP-Link help needed

harmeet_randhawa5 · July 18, 2016

I bought TP-Link modem last month from china. TL-WR941N V6. I wanted to change the language but after I flashed firmware of English version and it got bricked. Now all the LAN port lights are on and no other lights are on. When I power on the router only the WAN and LAN led's light up and are not blinking. No power led. Its also not broadcasting SSID. And when I connect it with LAN nothing shows. I cant use it now. I downloaded the Chinese firmware file but I dont know how to flash because the router is not detected in the computer. How can I revert it back to any firmware? Chinese also will work just it should start working. I tried to flash it with tftpd32 but nothing shows. Its like a dead router. Now I dont have access to serial cable also. Please tell a way to bring it back to life. Thanks for help.

Did you connect to the wan port and the correct IP address when you tried to flash the firmware via TFPT? Look here:

-----

Set up a TFTP server on your computer with the static address 192.168.0.66 - Put the image (without UBoot!) into the TFTP root directory and rename it to wr941ndv6_tp_recovery.bin

Now connect the WAN port of the router with your computer's ethernet port, power up the router and hold the reset button pressed (stop pressing the reset button when the lock symbol led turned on).
