You would need the correcponding correct TWRP, install it and root from there.
But unfortunately you need an account in the russian forum to download...

No need to register, I managed to download all the necessary packages, but still I do not work

How did you download?
Initially when I found it it gave me message that I don't have authorization, now it gives me 404 errors on the links...
Can you share the files'?

How about ...... I have the phone for at least a month, and I directly started looking for the procedure to rootearlo, and found this page. The Russians for these are very good, so I could rip the files, but after trying this option they mentioned, and did not work, in addition to others that I found on the web, and also be ineffective, I realized that with respect to this terminal The thing was still green, so delete the files although I assure you that they did not work at least on mine. In some ways, I'll look at my computer if I had them, but I think I got rid of them

this worked perfectly to install twrp on android 7.0 bv7000 pro with latest firmware, i used SP_Flash_Tool_v5.1724_Win though. TWRP is in russian but is easy enough to translate just looking at pictures on google translate. then i flashed SR3-SuperSU-v2.79-SR3-20170114223742 successfully. device is now rooted. thankyou very much

As I guessed, you just need a correct TWRP and then it's easy.
Now we need to find someone adapting this version to English language to make it usable as recovery.
Unfortunately I guess that OTA updates won't be working anymore, so you most probably would have to download the full ROM to flash with FlashTool...
