My BV6000 is running this release (20171011). It was quite long cause my previous one was 20160822. I had many problem installing MTK USB Drivers for Windows 10 64bits but it was ok after installing all the 5 drivers included in the Windows 10 x64 MTK USB Drivers.inf
With SP_Flash_Tool_v5.1728_Win, i Flashed 20171011 keeping my userdata (uncheck “userdata” so your data and setting may not be deleted), i got the green checkmark and i unplugged the phone.
On restart, i had many problem but the more annoying was with the continuous message « Launcher3 has stopped » « Launcher3 restarted » aso... I had to kill this app, delete all data used by this app, restart and everything is back normal.
My BV6000 is now proudly saying Android 7.0.
The last problem i have to solve is about WIFI cnx. This new version does not support WEP ... only WPA & WPA2.
Thanks to Blackview for the good work.
Regards from France.
