[Huawei P40 Pro Guides, News, & Discussion] pepo.k:
Hello dear experts

Checked all 7 tutorial posts on first pages and also almost all the messages in this long thread. Many thanks to Badmania and others for all the efforts.

My phone is p40 (ana-nx9 / c432); EMUI12; I tried several ways for enabling native GSM, some were working longer, some shorter, but now not more. But by the time I get used to live without native google apps.

A few thoughts/feedback/open questions from my side:

1. - Am I correct when I say, that the approach to certify with "Google Services Framework Android ID" on the google page, is not working at all for Huawei Phones like P40?

1.a - After one tries to do this approach, and afterwards warnings like "device not certified" occur on the phone; am I correct when I say, that there is no other way to get native GSM working, than to start from scratch generate new "Google Services Framework Android ID?

1.b - To get new "Google Services Framework Android ID"? we need to do factory reset and start from the very beginning from 10.1.0.131?

2. - My latest trial was to once again proceed acc. to EloYGomeZTv as suggested in post #4 section 1-b-V1. But I get stuck at the point (time 4:48 in his video) where I should "Force to stop" the google-play-services. The button does not go grey for me. So I can not stop it properly. 30x times clicked it, but still remains active. Any Idea why?

2.a - Nevermind, if I proceed and delete the cache and all data and then uninstall google-play-services. And go for install his version named: "1.apk", I got once again stuck, with comment: "Unable to install. There is already a newer version of this app on your device.". Why, what is different at my device?

2.c - I have tried once more - in different way - to re-install with the "1.apk" over adb but also no success.

I do not know why not, because at least this I could remember - in the past I have successfully push the older version over adb. But somehow not now. Any idea why?

3. - Another problem, what I have seen during the process of settling native GSM - How to disable google play protect fast enough before the play store updates the services to recent version? Or in other words - how to avoid the update in the background?

4. - Is this whole process of installing, de-installing, purging all the native google apps (or at least critical parts of the process) possible to automate with script to issue over adb shell commands (like e.g. with nested adb commands like: "adb install -r 1.apk", etc.)?

5. - Question aside - is possible to install harmony os on our european phone version of P40? Is it reliably working?

Sorry for long post! Do not sacrifice me please if I missed some of the posts where my open question was already addressed and answered.

I am searching here for a free solution(s), not waiting for private messages with proposals to connect to my phone or PC with teamviewer or similar remote software. To be honest I DO NOT TRUST! anybody!, I will not let any person which I do not know to connect to my PC or phone with all the personal data on it.

I always prefer to donate in afterward to smart people, which come with working and reliable solutions here on XDA.

Regards

Peter
