I have a tp link archer C60 V1 router.
I installed openwrt, but then I wanted to reinstall the factory firmware, from tp link.
Now I have this problem: only the power light is on.
I have tried from TFTP but it doesn't give me any signal.
I have connected by usb UART. He responds to me, but I can't install the firmware.
Firmware gives me error over and over again.
How can I install openwrt again?
If you have a switch, try putting it in between. Did you already flash the OEM firmware? OEM firmware includes the bootloader often, you would need to strip that if you'd try to flash it from within OpenWrt.
