Install GMS core Packages on brand-new Huawei
You can use YalpStore instead of google play store: 
https://github.com/yeriomin/YalpStore
https://github.com/yeriomin/YalpStore/releases
https://f-droid.org/packages/com.github.yeriomin.yalpstore

Just install the yalpstore zip as you would install a google zip. 

Please do not use androidapksfree.com . 
Apps from androidapksfree do not come directly via google and can therefore be maliciously modified, malware. Apps via yalpstore come directly and can't be modified. 

Also distributing apps via other channels like androidapksfree can be considered a copyright infringement (= crime) - apps from yalpstore come directly from google and can only be considered "violation of google terms of service". This is far less than a crime.
