I'm in the United States and need VoLTE to continue using this phone. I'm relatively new at doing this so please try to take that into account.

I've tried DLOAD method for 9.0.1.193 (C636E7R1P8T8) & 9.1.0.252 (C432E7R1P8T8). I got a message both times about the update not compatible with current firmware.

I'm guessing that I need to update to Android 8.0 before trying 9.0 but I'm not sure. I would appreciate specific instructions on how to upgrade this phone if it's possible.

My wife also has a Mate 9 MHA-L29. But it is a C567 and has Android 8.0. I haven't tried to upgrade her phone. But I need VoLTE capability for it too.
