How to reset TP-Link TL-WR741ND on OpenWRT?

Question

network hardware

Out of ignorance, I changed the LAN settings (I mixed it up with wan and put the pppoe item there and entered the provider's data) and now I can't enter the settings for both the web interface and telnen Tell me
how to reset.
In general, I noticed the following positions of the bulbs.
1. When the reset button is pressed, I turn on the router, the turn and the lock light up, then just turn and the gear blinks. Then it doesn’t matter whether to keep the reset or let go, nothing will change anymore.
2. If you turn on the router and immediately hold down the reset, as usual, the turn light will turn on and wait a bit, the gear will start blinking, and as soon as it starts blinking, I release the reset and the gear starts blinking even faster.
In general, in different modes I tried to enter by telnet, to no avail.

Thanks for inviting me to the discussion, sorry for the delay in replying.
If I were you, I would:
1) connect to the LAN and WAN ports in turn, see (wireshark) what traffic is being sent by the device. You may find active IPv4 or IPV6 addresses, try using them.
2) tried to connect via Wifi (if you remember the SSID and password)
3) soldered to the serial port pins on the board and would connect via the console

Well, there should be a button on the back. Clamp it with a needle or something else thin thread when the router is turned on and wait 10-15 seconds. I don’t know, maybe on OpenWRT it should be done differently, but you never know.
Still, on tsiska for example, this button should be clamped Before inclusion of a piece of iron in a network. So try again :)
