Cannot connect to router in failsafe mode

Installing and Using OpenWrt
1

Changed lan ip, had hardcoded gateway in firewall, lost access to openwrt router

when connecting via lan I get

ip route | grep default | grep -oE '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'
192.168.0.1
192.168.207.205

but I had disabled ssh :confused:

when I go to flash via tftp server I get

sudo /usr/sbin/atftpd --daemon --no-fork --logfile - /srv/tftpfire
Jul 19 21:28:26 debian atftpd[14163.139985222086400]: Advanced Trivial FTP server started (0.7)

and then it boots, the wifi shows up but the dhcp server does not asign any ip addresses to any device :confused:

Tried reset?

If you have, then this could help you to re-enable ssh The OpenWrt Firmware Selector - #341 by mwarning

the reset button on tplink tl-mr3020_v3 has not been configured

read some docs for failsafe and reset https://openwrt.org/docs/guide-user/troubleshooting/failsafe_and_factory_reset but besides the quick blinking light and getting the IP addresses mentiomed in the OP can't do much, can't mount/connect to do anything

can't flash a firmware as well

I read it as the flash works, but the settings are kept, might be wrong though.

If the LED is blinking rapidly, that should mean that failsafe mode is working. In this situation, you must connect your computer via ethernet, and it must have a static IP (such as 192.168.1.10, subnet mask 255.255.255.0). Make sure no other network conections are active on the computer (turn off wifi, unplug any other cables if you have more than 1 ethernet port). the LuCI web interface will not be running in this mode, so you must connect using ssh to address 192.168.1.1. Username is root and the password is blank.
