echo "All done!"

This is my code that bricked my router.

Now led stats like this. It’s not showing any response in recovery mode.

what recovery mode ?

you can always use serial.

3

Use tftp to flash a standard/default image.

4

Tried tftp, but no response. Will try in another client any deatailed guide

5

If you are using windows, disable the windows firewall. And remember - you need your computer to be setup as the tftp server the router is the client.

6

Any guide for that

7

Which version do you have?

8

tftp client or other

9

what serial please clarify

10

Sorry. I meant which version of the c6 do you have?

Edit - nvm. I see it in the first post. C6v3. One sec.

Here is the guide:

Nothing showing here firewall is off

12

Should be lan_ip_address="192.168.1.1/24" for 25.12. (CIDR notation)

13

Do you have a serial connection to imitate the tftp transfer?

14

Sorry I'm not following

Let me try again

16

Do you have the serial connection from the router to the c6v3?

17

Since you don't know what it is, try failsafe instead - https://openwrt.org/docs/guide-user/troubleshooting/failsafe_and_factory_reset

failsafe mode not working, not listening to the port… Ordered the UART for recovery.

The same issue happened with this guy TP-Link Archer C6 V3.2 EU: bricked after sysupgrade, no TFTP traffic - Installing and Using OpenWrt - OpenWrt Forum
