Maybe in furure I will upgrade to higher FW,
but for now I feel very comfortable with 3.41 and flashing always means a little risk to brick, and until now I never needed a higher FW. And showtime runs without any dongle, so as I told I only need it for installing a new showtime version. I try to prevent upgrading until I really need to for now

Of course I understand that it is even more comfortable that I wouldn't need any dongle anymore.
