I just received the Update which works good so far. But there is one thing missing for me. If I connected my Bv6000 to my pc (running an older Version of Ubuntu) I always used the option "use as USB-mass storage"(last option) because MTP never worked. Now this option is gone and I would like it back because I can't directly access the memory card from my pc otherwise. Maybe you could consider this in the next update.

You can try a newer (live) version if ubuntu to see if it helps. I have not seen usb mass storage in the usb options although i had the all the os versions starting from july 2016
