Full flash dump for the TP-LINK TL-WR840N router at hardware revision 6.20, sized for a 4 MB chip and marked as working, archived in RAR format. It serves to unbrick a router that hangs at boot or no longer accepts firmware through the web interface, by writing the image directly to the SPI flash with a programmer. Confirm the hardware revision on the device label and the chip capacity before writing, and keep a backup of the original contents, which store the unique MAC and radio calibration.
