Yes, it works fine.

You need to freeze GSF for that but then you lose the Play store and enhanced Google location services.

Don't worry this has nothing to do with your system update, this is something else. This is a new security check added by Google in their fight against unofficial GMS installations. It would have happened even if you didn't update your system. Actually it is happening to EMUI10 users too so....

That is an invalidated Play Certificate that you need to regenerate. Yes, it was probably valid for a while, then it got invalidated.

No, you don't have to follow that tutorial exactly.

Well you just found out the issue. Your apps, more specifically ONE of them is just too new: Google Play Services. It has enhanced detection for these kinds of hacks it seems, and it will bust your play certificate.

Don't do that.

Don't do that either.

Yes, that's almost what you need to do. But you only need to downgrade one of them.

That is correct, Google Play Services tends to get updated and as such, this issue prevails. Prevent it from being so.

Guys, you are doing it totally wrong. There is NO NEED TO DOWNGRADE your system software if you already have GMS installed. This has nothing to do with your system software version and you don't actually have to re-trigger the GMS installation (rights elevation/lzplay) exploit.

You just need to fix your Play certificate to stop those annoying play protect messages.

Yes, they added additional verifications. Yes, that was probably targeted against this hack, among others.

What you need is simply to download this pack:

Install Google Play Store by ICTFIX.net

MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.

www.mediafire.com

And then uninstall Google Play Services

then install this one: 7-GSM Play Protect certified Fix.apk

Then reboot

And the spam notifications should be gone.

Replacing Google Play Services with this app will force-regenerate your Play certificate,

and this version of Google Play Services does not have the problematic check in question.

Still you should NOT update Google Play Services as the latest version DOES have the check that will trigger this event again.

You do NOT NEED to install anything else from this pack.

Actually you could reupload this with only this file present.

Yes, it is missing that option. It is not supported anymore, and if you force it, you WILL HAVE PROBLEMS.

If you REALLY want to downgrade you can use HiSuiteProxy and an older version of HiSuite. However I don't recommend this for 3 reasons:

- it is unneccessary

- it is dangerous. You WILL lose USB connectivity after the upgrade, and you can only regain it when you update again to the latest system software version. And you can only do it with OTA.

- You can very easily brick your phone if you use HiSuiteProxy as it bypasses many of the firmware validation checks

+1 Huawei is changing things around with the latest HiSuite. Older versions will not work for software updates/downgrades for much longer.
