Thanks for the update.
TB v1.41.1379.0 didn't install for me. I did "Run As Admin" on Install.cmd, as usual and nothing happens. No install nor a reboot.
The only reason you "might" get lucky is because we all have been complaining to them the last 2 months about BIOS 2305, so we have a head start.
It's won't be because you are special.
