Hello blackview user,
i have an  old blackview bv7000pro on android 6 for my work. i m looking for switch on 7.0
i would like to know if someone have passed his bv7000pro from android 6 to 7. 
is it stable? what issue did you have (like broken micro, gps, etc...). is it better on 7.0 or not really?
thanks for your info and sorry for my english

dear Admin, i think you could help yourself with info as the latest, standard offical ROM is on Android 7. My BV7000 (without PRO) is also Android 7 and from the same production timeframe. No issues with Android 7 although the screen-problems (probably GPU clcoked to high) still exist with high-res photo's
