Firmware dump for the TP-Link Archer C80 AC1900 router, hardware version 1.0, as a 4.00 MB BIN file. The size suggests a full flash image rather than a web update file. It is written to the router SPI chip with a programmer to revive a unit that is bricked after a failed update or that loops at boot. Check that your hardware version matches v1.0, and read the original chip first, since it may hold the MAC address and calibration data unique to your device.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @hashmielecom. Enginerys does not host this file.
