-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
Quote:

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
Quote:

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!

Thanks a lot!
Since I've already grabbed packages from August 2017 to January 2018, I'll ask Chinese users who want to downgrade Nokia 6 TA-1000 to Nougat to give it a try

Hold power button for like a second, then click volume up and release both.
