    Got it!

    May I ask the source of this file? The FTS_Update is digital signed by Fujitsu on 2017, though the update is from 2014 according to the readme.

    I'm asking as the tools (andy's and UEFITool) is not recognizing the BIOS file. The original one and the 2.06 one are opening but not this one.

    I don't want to flash it blindly and get a bricked system. Also reading the txt file, now I know I can't flash anything older than 2.08 as I will got out of BIOS...

    Thank you.

    Just an update...

    I unpacked the files and the looked legitime. So I tried the update, without luck. But the modified file didn't check the old bios version so it flashed.

    I need to disconnect the battery, with the button, forcing the restart and now I'm on 2.09.

    Everything working as espected.

    Thank you very very much.

    Regards
