I had a problem with the Google services framework on my Mate 30 Pro.
The Huawei system kept telling me that this service framework drains the battery quickly.
Wanting to see a bit what was happening, I fiddled where I shouldn't have and deleted the data from the Play Services app ... and hat the Mate 30 Pro that I had with Google services installed since December 2019 has gone to hell !!!
My fault for doing what I should NOT do.
Following your last tutorial, and after a factory reset of the phone, when you want to install in STEP-1 the 2 apk files of the Backups (previously uninstalled following your video tutorial, the Mate 30 tells me that the Backup app exists a newer version on my device, and remove it.
And of course, I can't find it, and the Backup Copy doesn't appear in the Settings menu now to continue with the rest of the tutorial.
What can happen to me ??
Thanks and sorry for this
PS: I don't know if the new EMUI 11 version that it has causes it to generate any conflict.
The issue is that with this method, if I delete the Backup app that comes with the Mate 30 Pro, and I try to install the 2 apks that you provide in step-1, the phone won't let me install them because it already tells me that I have one latest version.
And then when I go to Settings, Backup is gone ... because I have uninstalled it as you mark in the tutorial.
ADDED: The message that I get after successfully uninstalling Backup, and installing the first Backup apk is:
Install failed
Reason: You already have a newer version of this application.
I asked to Eloy Gomez at a Spanish forum becuase he teached to me last december, 2019 how to install them following his tutorial but at the moment I don't received any reply.
