Firmware for the TP-Link TL-WR740N wireless router, hardware version 5.0, archived as a 3.33 MB RAR. Router firmware like this is used to recover a unit stuck in a boot loop or bricked after a bad update, either through TFTP recovery or by reprogramming the SPI flash with a programmer. Check the hardware version on the label under the router, since images for other versions are not interchangeable. Before writing the chip, read and keep its original contents, which hold calibration and MAC data, and confirm the image matches the chip size.
