Answer 1

I solved the problem for my Huawei P8 Lite Android phone like this:

1. I unlocked my bootloader like in this video
2. I rooted my phone like in this video
3. I succesfully checked with Root Checker Basic that my phone is rooted
4. I downloaded and installed System App Remover from the Google Play Store.
5. I put my device in Airplane Mode in order to prevent auto upgrade of GPS.
6. I opened System App Remover and select "System App" from the menu.
7. After I found Google Play Services in the list which was marked as "Should keep" I selected it and pressed "Uninstall". I ignored the next warning.
8. Using Settings/Apps, I saw that Google Play Services "Uninstall Updates", and "Disable" Buttons were no longer be grayed out.
9. I pressed "Uninstall Updates"

Here is the result: Downgrade of Google Play Services to 8.1.18
