[Huawei Mate X2] jsbutran:
Hello, Finally I was able to successfully install Google Play Services after looking at Youtube videos and other guides. And this is not through installing GSpace. But I was able to install built into the system. The Google Play Services on my HarmoneyOS 2 latest version works flawlessly with no security notification or problem whats so ever. All apps downloaded from the Google Play Store work perfect, All my accounts work perfectly. The device seems almost come with built IN Google play services.

All Guides/videos are availably in this forum. The problem with me and I think so many others are that we are not able to follow the sequence of the guide and troubleshooting videos. Having been able to successfully install myself, I would like to assist many more like me to install Google Play Services by just putting in the sequence already provided in the forum. Thanks to all of the experts for providing these do it yourself videos and guides. The only thing it requires is your patience and cool mind and of course, TIME because it may have to be repeated time and again to finally be able to achieve success. I take no credit and the entire appreciation and credit go to the original experts. The below guideline is just a sequence copy paste. Hope that will help everyone.
