Unlocked firmware for the UL50AT, compressed as a 698 KB RAR archive. The name does not give a version or chip model, and it does not explain what the unlock covers, so inspect the image after extraction. Use an SPI programmer to write it when restoring a board that will not boot or is locked. Check that the file size matches the flash chip capacity, read and save the original contents first, and confirm the board is a UL50AT before programming.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
