Full flash dump for the TP-Link TD-W9970 modem router, EU version, hardware V4, for a 16MB chip, in a 12.6 MB RAR archive. Although labelled BIOS, it is the router's complete firmware image, including bootloader and calibration areas. It is used to recover a bricked unit by programming the SPI flash directly when the web or TFTP recovery fails. Check the hardware version on the label, read out the original chip first, and keep the wireless calibration data from your own unit if possible.
