I got my BV8000Pro in Oct 2017. It also reboots at least once a day, and is power hungry too - as per the other popular thread.
I am on v0.1_20170803_20171011-0929 package. I have updated to that using OTA.
It reboots itself at random, at least daily (sneakily when I have left the room) then sits quietly waiting for the startup unlock pattern. Meanwhile in that state, it doesn't receive calls.
Today, I began to attempt to update to one of the later patches. OTA does not detect a newer release than the one I have. I tried the manual process, and even as a seasoned IT professional, I gave up, it was too fiddly, downloading unsigned drivers, from webpages full of other decoy download buttons for toolbars and other nonsense. I felt sure I would break the phone or laptop or fill them with badware!
Thanks for working on these issues. I do hope they are resolved, because the phone is great other than the battery usage and reboot issue.
