Hello, XDA.
All smartphones I owned, SONY Xperia Ray (2013-2017), SONY Xperia M2 Aqua (2017-2019) and SONY Xperia XZ Premium (from 2019) I finally modded using XDA forum to extend their life.
SONY Xperia Ray - official 2.3.4 to 4.0.4, then rooted, installed Android 5.1.1 on 64GB microSD card using system dedicated 16 GB partition and the rest 48GB as standard card partition
SONY Xperia M2 Aqua - official 4.4.2 to 5.1.1, then rooted, installed Android 7.1.2
SONY Xperia XZ Premium - official 7.1 to Oreo 8 to Pie 9, unrooted, but using j4nn temp root on Oreo, modified Pie OEM settings to allow VoLTE a VoWiFi for a Vodafone CZ
I decided to give a small piece of a Pie back to the community of what I found and that is why I registered to write down a guide of figured and tested steps to allow VoLTE a VoWiFi for a Vodafone CZ SIM on XZ Premium single SIM on Android Pie.
