Firmware dump for the TP-Link TL-WR841N router, hardware version 9.3, read from an MX25L3205 flash chip. That Macronix part is a 32 Mbit, or 4 MB, SPI NOR device. The RAR is 3.46 MB. A full dump like this restores a router bricked by a failed update or bad configuration and is written in-circuit or on a socket with a programmer. Check the hardware version on the label, because firmware for other versions of the WR841N is not interchangeable, and keep the original image for its calibration data.
