you can’t just remove everything by google that way. the google mobile services package is intehrated to the system in such a way, that uninstalling or even just disabling some of the core google packages will make it bootloop. I don’t know the specifics, but if you want to tinker, have a look at the opengapps installer. see what it is exactly doing in the package for your android version, and try to undo them manually with root. be aware though that its an unofficial project, manufacturers don’t use it, but trying to remove opengapps results in the same situation, so its installer can help you make sense of how is it installed.
