-Just download any zip OTA from December and before that, in my case I used this: https://yadi.sk/d/jfyLmpFH3Qomg8
-Put in on top of your sdcard and reboot to recovery
Turn off your phone. Charge it. Hold Vol up and Power for about 10 seconds. At No command screen briefly press Vol Up and Power again
-Flash that zip file you just downloaded. At some points it will say "Installation aborted"
-Congratulations! Now you are ready to reflash your phone with any Nougat nb0 rom as your sbl1 and aboot is downgraded
-Power off your phone and plug out. Open OST LA 6.0.4, load your rom and then proceed to flash it
-Links go here: https://mega.nz/#F!1ENgnThL!FyL9uYCC3Dq-16elThKAPg
-Open OST LA after patching with coressponding OnlineUpdateTool.exe, Next, select your nb0 rom, plug in your now turned off phone, Next
-Go have some coffee as it takes you for about 5 minutes
-As your phone boots up, wipe data then remove FRP the way you want
DO NOT USE 6.1.2 AS IT NEED AUTHENTICATON! PATCH THE OLD VERSION WITH NEWER EXE WON'T WORK!
Special thanks to @SimGa, @heineken78 and @the_laser for their discussion which made it available to downgrade this phone!

    It's not working. The links are down. It's not clear. The program needs authentification.
    This is a working version:
