Thank you for the idea. Let me try it.
I'm using Huawei P50 Pro Global with SD 888 chipset with latest EMUI
Try this to your mobile device
1)install Lighthouse from xda only without Lighthouse x
DON'T SING IN YOUR ACCOUNT FROM THE LIGHTHOUSE
2) make your device nexus5 - and enable cloud messaning - enable secure network
,after exiting the application do not close
3)install playstore version 16.8.17
4) open the playstore and put your account and it will open - if not - go to setting and clear storage off playstore and return to open -100%open FOR SOME MINUTES THE APP IT WILL DO UPDATE TO LAST VERSION
this way i have native playstore - search any app i want - install or update almost 2 months now without any device certification notification - working without any interruption
5)i also install after this beacon from malaysia app collection - it's like an update - you already have your account from old beacon so you will see that the app doesn't serve your devices but do not care the playstore still operates
I DO NOT HAVE GOOGLE SERVICES FOR GMAIL OR YOUTUBE OR ANY APP NEED GSM - this is working to mate 40 pro china version with harmonyOS and kirin and i do not known if is wokring to P50pro with SD888 but you can try and tell us - i believe the SD888 probably let someone <secret door) for google apps....
