Hi and thanks for support.
It's clear that BV6000 with Android 7 it's a wrong choice, cause tons of problems that everyone knows.
So, please, can you provide the exact guide to downgrade it to the latest Android 6 versione?
Thanks again in advance

1) For me the latest Android 7 ROM is working stable if you make a factory reset after the update!
2) Just use the flashing tutorial and flash an android 6 ROM

I've already installed latest 7 ROM but I've same old problems, better downgrade.
Wich kind of ROM I've to use? I see a lot of it
Tnx again for support
