I unzipped the zip and through root explorer I put the necessary files into the system / app. Then I gave the rights to the files and rebooted! In the first phase I wanted to activate call records in the call menu but I had an error and the sims have restarted. I thought it did not work but then I deactivated volte and wificall. The surprise was that we were able to activate the call recording and called. At the end of several test calls we found that the recordings were made and appeared in the record menu.
After this episode I gave a reboot on the phone. I switched on volts first and went! Then I activated wificall and it was good.
It also records volts and wificall and the quality is very good.
So the patch works, but the volts and wifi call must not be activated on first use!
Thousands of thanks !
I did not use twrp because I installed the supersu through a direct write with adb!
My phone is Mate 10 Pro BLA-L29C432 Europe
