I have a lot of problems with the Thunderbolt FW Update Tool... I always get the error that there was no thunderbolt controller found, after I had to reinstall Windows for some other reasons, the tool worked for the first time right after the fresh install. I waited till 100%, shutdown the PC and pulled the power cord like I was told to do. After that I started the PC again, tried to start the upgrade program again with the expectation that I see something like "FW is up-to-date" or something like that... but instead the old error message reappeared! That there's no thunderbold controller! I didn't change anything between those 2 restarts... So now that there's a new version out there, Thunderbolt FW Update Tool B16.0201.1" I was hoping that the tool would work at least one time again... but no luck... Anyone else with similiar problems?
My bios version is F7K and my thunderbold software version is 15.3.39.250... so that shouldn't be the issue here.
