Can't login to TP-LINK tl-wr940n router after flashing OpenWRT. What to do?

Question

network hardware

Hello everyone, I ran into an unpleasant situation, after a thunderstorm the van port burned out, and since the standard firmware did not allow ports to be transferred. Changed to OpenWRT.
After the firmware, I went to the router and, according to the instructions ( goo.gl/uPBiWp) , performed the settings.
The port turned out to be transferred to 4 and everything worked on wi-fi, but the LAN ports recognized the network as without the Internet.
After changing the LAN settings, I chose Vlan Interface eth1.2 and WIFI.
Everything, after that I can not go to the router.
It connects via Wifi as an unidentified network and does not even ping, I already tried to manually register IP, it didn’t help, it’s the same through the wire.
I tried to enter in safe mode, it did not help.
Resetting by holding the "Reset" button does not work.
Maybe someone knows how to solve this problem?

Answer 2

you can try to restore your native firmware in a standard way via tftp
1. Download the firmware from the tp-link for your model, look carefully at the version!
2. Register the computer with IP 192.168.1.66
3. Download and run the tftpd32.exe server
4. Turn on the router with the reset pressed, release it after 5 seconds
5. Look in the tftp server log for the name of the file that the router requests.
6. Rename the firmware file to the name in the previous paragraph, put it in a folder with tftpd32.exe
7. Repeat step 4.
8. Wait for the firmware to finish, first in the tftp server log it will be seen that the firmware has poured, then wait 3-4 minutes until the end process.
9. Go to the router at home address 192.168.0.1
10. Mock the router further by rolling openwrt, etc...
