[GUIDE] Downgrade from OFFICIAL Oreo to Nougat

[wolfyapl]

-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!

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

Yes, maybe Nokia think it will good for user. But I feel it is alarmist.
BTW, Can I share this method to Chinese forums (like dospy,ithome etc)?
