What is this link? Its real A7? Its safe?

I can't update via 'local update' to ROM version 20161025. When I try it, it stand 'restart' but nothing happened.
On my phone is ROM version 20161011 installed. Is there an version of ROM 20161025 to flash with SP-Flash-Tool?
Or can I maybe update the OTA version with Recovery-Mode?

How do we know if we recive it or not, depening on if OTA works?
Is there a download file or something? I really hope this fixes ALL of the problem this phone has.

I have the 20161025 ROM
I love the on going support

Blackview makes some good phones, I also have a A8 Max

What is any update or new feature on nougat?

Will I be able to disable built-in apps like clock and calendar?
Will it stop the WiFi being constantly on?

I've tested this update and only found one bug, no 4G o2 UK. The ROM appears quite messy, so may be beta ROM. Also you can not roll back to Android 6 without a format and download with flashtools, so make sure you have a full TWRP backup.
