Unlock firmware for the Lenovo ThinkPad T440s, a patched image of about 3.7 MB in RAR form. Such patched dumps are commonly used to bypass a supervisor password on these models by flashing the modified file to the relevant SPI chip with an external programmer. Keep a backup of the original contents so serial and UUID data can be restored, check which chip the image targets by size, and follow the usual procedure documented for the T440s before powering the board.
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 @biosarchive. Enginerys does not host this file.
