Hi All,

I was wondering whether its currently possible to downgrade back to EMUI 9? I received my Mate 30 Pro today (Model LIO-AL00), and it came with Android 10 out of the box. It has also applied a bunch of updates and I am now on 10.0.0.135.

I have tried the various guides to side-load Gapps via the backup method. Whilst the Gapps install, I can't open them. LZplay also doesn't want to start. I've tried all sorts of guides (including: https://www.gearbest.com/blog/how-t...ll-google-apps-gms-on-huawei-mate-30-pro-8639) but they all fail.

I also stumbled across the thread that talks about using Virtual Exposed (https://forum.xda-developers.com/mate-30-pro/how-to/microg-t3977821). I can get Virtual Exposed installed, and the play store installed, but it doesn't open either.

So, I was wondering whether its possible (somehow?) to downgrade back to EMUI 9, so that I can use the LZPLAY method?


Thanks!!

Don't need to go back to 9. You can still get playstore on emui 10. I did it yesterday. Guide section install Google Play guide works. Rithina is op

Thanks for the quick response! Could you tell me which method you used, and what version of EMUI you did it on? Feel free to send me a private message if you don't want to share it publicly. Thanks! :)

I had seen that post, and I had tried it yesterday without any luck.

This morning I reset the phone and started again. Following the link from this thread: https://forum.xda-developers.com/mate-30-pro/how-to/install-gms-google-play-store-t3992095

I managed to restore the HiSuite backup (only apps and settings)
Installed Google Apps fine
Started LZplay, but then get connection errors (see screenshots)
Do I need to VPN into China for this to work? Because the phone is trying to get to https://api.lzplay.net, which no longer exists.
It also tries to go to http://configdownload.dbankcdn.com/ which is also throwing an error.

Any ideas?

Lzplay is meant to not work. Now close it and install all the Google system apps and play store. Give them all permissions they ask for.

Hi Mate, I have done that, but none of them work. These instructions all follow the same pattern, and I have tried 4x different methods now. None work.

NOTE one thing: I cannot use HiSuite 9.0.3_300 to restore the LZplay backup. I am forced to use 9.1.0_309OVE because of the Android version on my phone. That is the ONLY thing that deviates from the instructions!

This one doesn't work: https://forum.xda-developers.com/ma...all-google-service-huawei-mate30-pro-t3992171

I can get the backup restored and all apps installed, but they just don't work . I made this video show the situation; https://youtu.be/BkAxzTzwPuQ

Should this still work with a later version of HiSuite?

So lzplay has admin rights? Have you tired istalling the Google apps again over themselves without uninstalling them first?

OK, I FINALLY managed to get it working. I followed these instructions:
Download and unzip the lzplay package (this contains the most important application data to be restored, please do not confuse with the newly downloaded lzplay package)
2, connect Hisuite (pc Huawei mobile phone assistant) click data recovery
3, find lzplay decompression package, only restore applications and data (only restore assistant application and application data, application data is the most important! application data is the most important! application data is the most important!) does not restore system settings!
4, restart the phone after data recovery
5, then download the corresponding version of the Google package and install (corresponding to the Google package and lzplay link below) Note: Install these Google packages based on all permissions
6. After the installation is complete, open the Google Service Assistant and activate the device manager.
7, restart the phone after activation is complete
8, open the settings drop-down to see if there is a google icon, if there is, then the installation is successful, if not, repeat the installation steps
MOST IMPORTANTLY: Open GMAIL first, register your account, and Google Play should then also start working.

The first couple of times I tried to either add a Gmail account or go directly to the Playstore, which didn't work. Now I opened Gmail, added my address, signed in and it all started working!

Thanks for all your input guys. Much appreciated!!
