openwrt on tp link. How to install on tp link archer c59 v1.0ru router?

Question

TP Link

I uploaded openwrt via tftp to archer c59 v1.0 ru. Rebooted. But the tp link firmware also remained. Maybe he didn't do that?

these instructions

Downloaded wireshark
Connected the router. I looked at what IP and file I needed (there was the name tp_recovery.bin)
I downloaded the openwrt firmware. Renamed to tp_recovery.bin
Changed the IP gateway in the control panel (on the PC)
Launched the tftp program. Selected the folder with the tp_recovery.bin file. Selected a network card. Connected the router. Began to start it with the reset button. After 5 seconds, the download started. Lasted 1 second. Completed successfully. Then the router started to boot into the stock firmware
